- Jillian Holtzmann; Ghostbusters

Dr. Jillian Holtzmann[1] (also known as Holtz[2] and Holtzy[3]) is Ph.D specializing in experimental particle physics,[4] is a former associate professor from the Kenneth P. Higgins Institute, and is a founder of the Ghostbusters in the 2016 movie, along with Doctors Abigail Yates and Erin Gilbert. Utilizing nuclear engineering, she designed and built their equipment, including the Proton Packs and Sidearms.[5]

HistoryEdit

Primary CanonEdit

Jillian Holtzmann attended MIT[citation needed] and was a brilliant engineer considered for a position at CERN, the European Organization for Nuclear Research.[6] However, there was a lab incident and a man went into a coma.[7] She worked with Abby Yates at Kenneth P. Higgins Institute where she was an associate professor of paranormal studies.[8] Abby and Holtzmann went to work actualizing theories from Ghosts from Our Past: Both Literally and Figuratively: The Study of the Paranormal like a hollow laser for the reverse tractor bream.[9][10] Holtzmann heard terrible things about Erin Gilbert from Abby.[11] The day before meeting Erin, Holtzmann heard the lab victim woke up but he screamed then went back into a coma.[12][13] Erin met Holtzmann after she confronted Abby about putting Ghosts from Our Past back into circulation online. Abby warned her not to get too close to Erin or she would ask her to write a book, and then squash her dreams. Abby boasted Holtzmann was brilliant and loyal, listed some of her accolades but mentioned the lab incident. Holtzmann suggested letting her listen to the EVP. Erin interrupted Holtzmann and told her she knew what it meant but none were ever substantiated. Annoyed by her cockiness, Abby played along and they told Erin a story about how they spent eight nights at the Chelsea Hotel a few months ago then found something when they reviewed their tapes. Abby started a tape on the Kudelski Nagra III Reel to Reel Tape Recorder. Holtzmann and Abby leaned in to listen. Erin approached and suddenly a recorded fart sound plays. Abby mocked her with a spooky "ooo" noise while Holtzmann laughed. They realized Erin was the first to come right over to the recorder. Abby was concerned when Holtzmann asked if it was more or less disgusting if the noise came from the front. The hilarity ended when Erin told them about Ed Mulgrave Jr.'s claim that the Aldridge Mansion Museum was haunted. Abby and Holtzmann performed an elaborate patty cake then grabbed some equipment.

Garrett called out to Erin, Abby, and Holtzmann from the sidewalk across from the Aldridge Mansion. After some confusion about which Ed Mulgrave Erin talked to Abby asked him when the last time the entity was seen and how he ranked it according to the Ghostly Interactions Rating System. Mulgrave answered Garrett saw it on Tuesday and soiled himself. Garrett denied it. Holtzmann speculated it was a T4 if poop was involved but she couldn't suss out if that was a result of the ghost or eating something weird. Abby was ready for the tour but Garrett threw his keys on the ground and told them they were going to die in there. Holtzmann went along with Abby and a reluctant Erin inside the Aldridge Mansion Museum. Holtzmann held a can of Original Flavor Pringles under one arm while filming the investigation with a Sony 4K Camcorder. After Abby tried unsuccessfully to open the basement door, Erin tried to push the camcorder away but Holtzmann pointed it back at her and asked where she got the world's tiniest bow tie from then what it was like to walk around in high heels all day. Abby called Holtzmann over to the library. Erin stepped on Ectoplasm then witnessed the basement door open. She thought she was being pranked again but both denied they opened the door. Abby and Erin experienced an AP-xH Shift. Holtzmann directed their attention to the door. They observed a blue glow coming from the basement, Abby took over with the camcorder and recorded Gertrude Aldridge. Holtzmann couldn't stop eating Pringles. Abby couldn't believe they were finally seeing a ghost. Holtzmann assured her they were. They watched as Erin was ecto-projected on by Gertrude at 2:09 pm. They hurried outside and Holtzmann spotted her first. They watched Gertrude fly away at 2:14 pm. They celebrated. Holtzmann danced and echoed they saw a ghost.

Erin returned to the Paranormal Studies Laboratory after she got fired. She grabbed the nearest thing, a Proton Grenade (Air Filter Prototype). Abby and Holtzmann freaked out and exclaimed they would all die and turn to ash from the inside out. Abby instructed her to put the grenade down slowly. Erin slammed it down on a pile of components. Abby and Holtzmann gasped. Erin couldn't believe she got fired after years of hard work and ass-kissing. Abby tried to spin it into a glass half full scenario since they saw a real ghost. Holtzmann agreed it was beautiful until she dislocated her jaw and ecto-projected all over Erin. Abby declared they weren't going to be quiet about in then asked who people were going to call for help. She felt like they were on the cusp of a real discovery and told Erin the Institute backed her and Holtzmann 100 percent. Erin became interested. All they had to do was go upstairs and ask for more money. Abby promised they would pumped if Erin joined. They met with Dean Thomas Shanks in his office. He had no idea Abby and Holtzmann's department still existed and fired them. Holtzmann, Abby, and Erin gathered everything they could and wheeled it outside the Institute. Abby stressed it was just a minor setback. Erin was undaunted and believed they could become the first scientists to prove the existence of the paranormal and all they have to do was find an entity and capture it and bring it into a controlled environment. Abby welcomed the "old" Erin back into the fold. Holtzmann was pleased. Abby warned they should leave quickly since they wanted it back. Erin thought it was all theirs. Holtzmann admitted it was all stolen school property. Shanks appeared at the front door with a bat and demanded it back. Abby ordered everyone to scatter. Erin gritted her teeth. They ran for it. Shanks started to run down steps after them

Abby, Holtzmann, and Erin started looking for a new place of operations. A Rental Agent claimed she found a fantastic spot for their business and introduced them to a firehouse in Tribecca at 14 North Moore Street. Abby and Holtzmann loved it, especially the height and the space. Abby and Holtzmann hugged one of the beams. Abby joked the fire pole was a stripper pole. Erin learned the rent was $21,000 a month and told the agent they needed to explore something a lot cheaper. They ended up picking a much more budget friendly location in Chinatown. During the unpacking, Holtzmann started dancing and lip synching to DeBarge's "Rhythm of the Night." She used a tool like it was a microphone. Erin smiled but realized Holtzmann now had two lit torches. She called for safety. Holtzmann lit some equipment on fire. Holtzmann danced back with an extinguisher and neutralized the fire. Erin thanked her then Holtzmann pretended to go walking down stairs behind her table. Abby couldn't resist using DeBarge as a pun and laughed. Holtzmann thought she was playing a Devo song and turned it off. Kevin Beckman passed by the doorway then peered in. He inquired about the job opening for a receptionist. Erin was instantly smitten with him. Holtzmann wondered if he was a robot. During the interview, Holtzmann asked Kevin what he had been doing with his whole life. Kevin scratched his eyes through his eyeglass frames and replied he had lots of different jobs like acting. Abby interjected and asked why his eyeglasses had no glass. Kevin told them they kept getting dirty, so he took them out so he didn't have to clean them anymore. Abby was speechless.

Kevin asked it was okay to bring Mike Hat to work sometimes because he had major anxiety problems. Abby revealed she had pretty severe cat allergy. Kevin corrected her and said he was a dog. Abby asked if the dog's name was My Cat. Kevin said it was Mike Hat. Erin realized his first name was "Mike" and his last name was "Hat." Kevin added his full name was Michael Hat. Abby admitted she wasn't allergic to dogs. Kevin replied it was all right because Mike lived with his mother. The first design was a female ghost with large breasts. They were speechless. Erin finally asked him if he saw how that might make them look bad. Kevin wondered if was the boobs they didn't like and offered to make them bigger. Abby and Erin remarked they saw them. Holtzmann revealed Ghost Tits was her nickname in middle school. Kevin replied nonchalantly. Kevin's favorite was a hot dog floating above a house. Erin thought it was a mistake. Kevin explained the floating hot dog implied that a ghost was holding it. Abby gasped in realization and admitted his work was more cerebral than she expected. Holtzmann asked why a hot dog. Kevin revealed he just like hot dogs because they were both food groups, all in one. Dogs and buns. After a short discussion, Kevin was hired. A woman named Patty Tolan, who was waiting outside, came in and told them some trivia about Zhu's then abruptly revealed she was chased by a ghost.

They went to the Seward Street Subway Station and talked to a Graffiti Artist who claimed he saw a ghost, too. He disobeyed Patty and spray painted a white ghost onto a wall then sprayed a red No logo around it after Patty told him she didn't want it anymore. Patty was annoyed and yelled at the trio to follow her to the tunnel. Holtzmann paused and took a picture of the graffiti art with her phone. She thought it was a good logo. She reminded the others she couldn't load the Proton Box off the platform by herself and it was both untested and highly unstable. Abby found scorch marks left by the Hyper-Ionization Device. Patty confirmed that was where she saw the "weird sparking thing." Holtzmann asked what it was. Patty remarked if she knew what it was, she wouldn't have called it "a weird sparking thing." Holtzmann liked how mouthy she was. Erin picked up a piece of the device and observed fission scorch. Abby didn't believe her then realized she was right. She guessed she smelled both electrical discharge and isotopic decay. Abby agreed. They smelled it again and both nodded. Abby called Holtzmann over for her opinion. She sniffed it. Patty reminded them they only had a couple of minutes left. Electricity cackled and the P.K.E. Meter spun rapidly. Holtzmann saw something. Erin thought she was messing with them. Holtzmann denied it. Erin and Abby saw it. The Electrocuted Ghost was back. Abby asked Patty for some illumination on the ghost. She complied. It looked scarier. Holtzmann walked back to the Proton Box and powered up the Proton Box, typing on a keypad.

Holtzmann cautioned the technology was in its early stages. At 4:21 pm, Holtzmann handed a bulky particle thrower to Erin. Holtzmann told her the thrower was going to shoot a proton stream at the ghost and instructed her to wait for her go ahead. Erin inquired why she was operating the untested nuclear laser. Holtzmann noted she had the longest arms. Patty advised them to hurry up. Holtzmann remembered she forgot the most important part and placed a collar around Erin's neck for a little bit of grounding so she didn't die immediately. Holtzmann asked Erin if she knew her iron level. She did not. Holtzmann told her it was fine. Abby chuckled. Patty asked them if they caught a ghost before. Holtzmann gave her the green light to aim and fire. The proton stream fired but stopped way short of the ghost and drooped into the ground. Abby suggested more power. Holtzmann tried again. Erin fired off a sustained stream and wrangled the ghost but it was still coming at them. Erin asked if the stream could get any stronger. The ghost growled and thrashed at them as the stream entangled it but it continued to close in on Erin. The ghost pawed at her. Erin gasped and fell on her back. Patty alerted them the train was coming and it was time to leave. Abby asked Erin to lure it back on the platform. The Proton Box fell on its side. They pulled Erin to the platform. The train closed in. Patty realized that was the express train, which meant it wasn't stopping at the station. Holtzmann quickly removed the collar. The train rammed the Proton Box and the ghost and drenched most of them in Ectoplasm. The ghost found itself inside the moving train away from the station. Holtzmann was excited. She had a clear idea how how to add more power and make the technology more mobile. Erin remarked she almost got killed. Holtzmann thought it was so awesome. Abby agreed.

With the results of the subway field test, Holtzmann worked on the Mark I Proton Pack while Erin and Abby went over the pieces of the Hyper-Ionization Device. Erin brought up the fact that the pieces looked like it was part of a miniature cyclotron. Holtzmann added whoever built it used a chromium alloy for the hull. She scoffed and admitted she would have used aluminum but that was because she was crazy. Patty wanted to join the team and pitched what she could contribute. She added she could borrow a car from her uncle so they wouldn't have lug all their heavy equipment around. Holtzmann loved the idea of getting a car. Some time later after being accepted to the team, Patty returned in a black 1984 Cadillac Fleetwood hearse and honked the horn. Abby, Erin, and Holtzmann came outside. Patty mentioned her uncle owned a funeral home to which Erin joked she hoped Patty checked to see there wasn't a body in the back. Patty admitted she didn't know. Abby was surprised she didn't check. Patty insisted she was in a hurry and only checked to see if the car had gas. Abby asked if there was a body. Patty retorted Holtzmann should check. Holtzmann thought of seven good uses of a cadaver right off the bat. Patty stated they had to turn in the body if there was one in there. Holtzmann made a face. Patty told her not to do that.

Holtzmann presented the finished Proton Pack and reminded Erin she almost got killed in the subway. Erin clearly remembered. Holtzmann informed them she added a booster using microfabricated radio-frequency quadrupoles to speed up particles before entering the DLA device and made it portable and wearable for maximum flexibility. Erin was impressed. Abby revealed they just had to add the reversible psychokinetic energy sink and Holtzmann's hollow beam to a canister and they would have something to hold a ghost. Abby held it up. Abby and Holtzmann performed a complicated patty cake then went outside to test the pack in the alley between Zhu's and its neighbor building. Erin proclaimed it was an exciting moment and told Holtzmann she was beyond impressed. Holtzmann instructed Abby to plant her feet firm and bend her knees to compensate for the extra kickback. Abby turned the pack on and liked the "purr." Holtzmann directed her to the practice target. It was a generic ghost cutout with a bulls eye drawn on its chest. She told Abby to put her thumb on the red trigger button. Abby fired and blew up the target but the kickback took her across the ground then up into mid-air. Holtzmann called her impression of a deflating balloon marvelous. She revealed all they could do was let Abby ride it out until the pack was out of power then she could make adjustments.

They settled back inside and ate Papa John's delivery pizza. Patty asked Erin and Abby how they met. Erin answered that Abby transferred to her high school during their junior year and they bonded right away but thought what all the other kids were doing like getting drunk and going to parties was stupid. Erin added they weren't invited to any parties. Abby believed they were terrified of them. Abby remembered something else and walked off to go get it. Patty then asked how they got into ghosts then if one of them saw one before. Erin admitted she did, when she was eight years old, the ghost of her mean neighbor Gretta DeMille stood at the foot of her bed, just staring at her for every night for almost a year. Patty and Holtzmann were surprised. Erin continued and revealed her parents never believed her and sent her to therapy for years, then the kids at school found out. They teased her and called her "Ghost Girl." Abby was the only person who believed her. Patty stated kids were mean and told Erin she believed her. Erin thanked her. Holtzmann had some questions. Patty reacted, "Seriously?" Holtzmann winked and smiled. Abby returned with a photo of teenage Erin and Abby with a science fair presentation. Erin wished they still had the presentation and bragged it was pretty great. Patty kinda wished she could've seen it. Abby hinted she might just get her wish. She ran off exclaiming. Erin realized she had it. Patty regretted speaking out. Abby and Erin, now dressed in all black turtle necks, reenacted their high school presentation and sang a song about the existence of ghosts. Holtzmann thanked Patty for requesting it. Patty was at a loss. They sang about a barrier that stopped served as the last line of defense between the worlds of the living and the dead. Erin and Abby chanted, "Protect the barrier!" or mankind would end. Holtzmann walked towards them doing a slow clap. She declared she so goddamn happy there were friends again then embraced them.

Holtzmann noticed they were on TV. NY1 dubbed them the "Ghostbusters" and did a piece on the video about the Electrocuted Ghost. Patty was shocked and declared they were famous. Pat Kiernan played a recorded clip with Martin Heiss from the Council for Logic and Data and a famous debunker. In the clip, Kiernan asked Heiss if the video was real. Heiss told him it wasn't and laughed. During Erin's speech, Kevin answered a call from the Stonebrook Theatre and informed them there was a goat on the loose. Holtzmann ran off to get the hearse. She pulled up in the hearse but it was fully decked out and repainted white, Ecto-1. Abby exclaimed. Patty was shocked at what she did to the hearse. Holtzmann claimed she fixed it. Patty found it inappropriate for a hearse. She couldn't take it back in its current state. Erin finished telling off her ex-boyfriend Phil Hudson when Holtzmann and Patty called out to her. Abby told Phil not to follow. Holtzmann drove a few inches forward when Erin tried to open the door. Erin played along. Holtzmann told her they had to go. Erin walked to door. Holtzmann drove forward. Holtzmann asked her to get in. Erin told her it wasn't the time to mess with her. Phil just stood there and stared. Holtzmann quipped to Erin, she was killing her then remarked they had fun then drove off.

They met Jonathan the Theater Manager and he told them about his encounter with Mayhem. The team split up downstairs and searched for the ghost. Holtzmann put on a purple wig and hat and spooked Erin. Erin wasn't amused. Holtzmann placed the wig back on the shelf and followed her. Abby found the Hyper-Ionization Device and radioed everyone. Patty arrived last. A possessed mannequin kicked a hole in the door near Patty's crotch. Patty screamed then ran over to the others. It kicked its way in through the door. Abby realized the ghost performed a full paranormal transferal embodiment and her and Erin's theories on spectral possession were true. Erin wanted that ghost. They opened fire on the mannequin. Mayhem emerged as they blasted the mannequin. They chased it down the hall and fired at it. Mayhem got away and flew up through the ceiling. The Ghostbusters ran onto the stage after Mayhem shoved the lead singer of the Beasts Of Mayhem into the speakers. They opened fire starting with Patty then Erin then Holtzmann and lastly, Abby. Mayhem dodged the streams and ended up perched on Patty's shoulders.

Abby signaled the others to shoot Mayhem. Erin told Patty to stay still. Abby asked everyone not to hit Patty anywhere important. Patty exclaimed. Erin, Abby, and Holtzmann shot Mayhem. It screeched and hopped off Patty's shoulders. Patty fired at it, too. Holtzmann remembered and warned Erin to never let their beams get entangled or there would be a counter reaction. The beam would shoot back into her body, and each atom will implode. Erin exclaimed. Abby told Holtzmann to open the Trap. Holtzmann turned off her thrower and reached for the Trap on the underside of her Proton Pack and threw it onto the stage. Holtzmann informed them she was going to open it on three. Patty exclaimed at Holtzmann. She swiped her remote trigger. The wired pedal shot out from the side of the Trap. Holtzmann counted down to two and rested her foot above the pedal. Patty yelled at her to open it. Holtzmann quickly counted down to one and stomped the pedal. The Trap opened. She resumed firing at Mayhem then told Erin and Abby they were doing great but asked Patty to try a little harder. The Trap pulled in Mayhem. Holtzmann stomped the pedal. The Trap closed. Patty ran back up to the stage. Erin asked if they caught it. Holtzmann declared they put a ghost in a box. She held out the Trap as steam hissed from it. The crowd cheered. The Beasts resumed performing their song. Holtzmann grabbed the guitar away from one of the performers and smashed on the stage. The crowd cheered. Holtzmann whooped. She tossed the guitar back and said she couldn't pay for it. Outside, a NY1 reporter asked they why there were ghosts in New York. Holtzmann declared they made magic and identified herself as Holtzmann then held the Trap up in the air.

Back at headquarters, the Ghostbusters celebrated to DMX's "Party Up (Up in Here)" single. Holtzmann got their attention and showed off her work on the Mark II Proton Pack. In one breath, she rapidly told them she installed some newly printed circuit boards, rebuilt the superconducting magnets, improved beam accuracy by adding a plasma shield to the RF discharge chamber, added a cryocooler to reduce helium boil-off, and a Faraday cage to attenuate RF noise and avoid quenching. Erin and Abby were impressed. Kevin interrupted and informed them there was a "Smartin Christ" to see them. Erin was confused and realized he meant Martin Heiss. Things started poorly with him asking why they were pretending to catch ghosts. Erin picked up Trap and told him it was inside it. Heiss pointed his cane at the Trap and wanted to clarify the ghost was indeed inside the "thermos." He poked it but Abby pushed the cane away, telling him not to touch it. Holtzmann remarked, "Booyah. Emphasis on the "boo"." Heiss replied he would really love to see it but Abby shot that notion down but Erin grabbed the Trap back and released the pedal. Holtzmann and Patty quickly strapped on their Proton Packs. Mayhem was released and he carried Heiss through the window and dropped him onto the street. Holtzmann broke the tension and quipped he wasn't really Ghostbusters material. Officer Stevenson took their statements and asked who threw Heiss out the window. Holtzmann replied a ghost threw him out the window. Agent Hawkins and Agent Rorke flashed their Department of Homeland Security badges and informed the Ghsotbusters that the mayor wanted a word with them.

Mayor Bradley welcomed them into his office, apologized for the drama, and asked them to take a seat. Holtzmann flopped onto the chair on the end near the agents, slouched, and put her feet up feet. Bradley scolded her. Abby tugged at Holtzmann's boots. Erin started with saying they didn't have a lot of time and they were not frauds. Bradley interrupted and stated they knew they were not frauds because they were monitoring the situation quite closely. Bradley asked the Ghostbusters what they knew. Erin revealed that they believed that someone was creating a device that attracted and amplified paranormal activity. Abby added that activity was escalating now and leading to an even larger scale event. Bradley joked that sounded terrible. Holtzmann gestured an explosion. Bradley complemented them on the great work but told them it was time to knock it off and let the government do their work. Lynch added they were worried that they were drawing a lot of attention to themselves. Bradley agreed. Holtzmann feigned surprise. Agent Hawkins pointed out they drove a hearse with a ghost on it, and used a distinctly un-American-sounding siren. Hawkins asked them if they had any idea how many federal regulations they broke on a daily basis. Holtzmann asked if it was one. Agent Rorke replied no. She asked if it was two. He replied no. She asked again if it was one. Rorke told her to just sit quietly. She made a face and reached for his chest. He brushed her away.

Bradley and Lynch explained that they planned to make the public believe the Ghostbusters were frauds in order to prevent mass hysteria. Erin agreed but felt like the cat was sort of already kind of out of the bag. Erin and Abby got into it about the meaning. Rorke intimated that the cat had been out of the bag before but people lost interest and put it back in. Lynch added people always moved on. Rorke told them about a sheriff in New Mexico who reported a UFO encounter, the crew of the SS Ourang Medan who died mysteriously, and the entire town of Langville, Montana who went missing. Holtzmann feigned shock. Abby explained they were talking about relocating and not about anyone being killed. Bradley stated they were turned inside out. Erin asked if their skin was on the inside of their body. Bradley confirmed that was true because their organs were on the outside. Abby asked if they were okay. Bradley curtly answered "sure." Holtzmann thought they were dead. Bradley thanked them for coming. Agents Hawkins and Rorke dropped the Ghostbusters off outside Zhu's. Rorke declared they were taking it from here and the US government doesn't need the help of hobbyists. He told them to go back upstairs to their little dim sum tea party and leave it to them because they were the big dogs. Rorke abruptly ran to the front passenger side door of the lead SUV. He gestured 'I'm watching you' and opened the door and partially sat on agent already seated inside. Rorke apologized to him. Abby called them meatheads. Rorke walked to the rear SUV. He tried to open the front passenger door. It was locked. He tapped on the window and asked Hawkins twice to unlock it. Hawkins told him to wait. Rorke got in. He lowered the window down and gestured and shouted repeatedly 'I'm watching you' as the SUVs departed. Holtzmann asked the others if they thought they had genitals in there or was it more of a Ken doll situation. Rorke repeated he was watching. Abby went with Ken doll situation.

Holtzmann stated they had to be prepared and presented new sidearms on a wooden table: three Proton Grenade (Air Filter)s, a Proton Grenade Launcher, a Ghost Chipper, a Proton Glove and a Proton Blaster. She invited Erin to pick any one. Erin picked up the Proton Grenade Launcher. Holtzmann freaked out and told her that one wasn't ready but when it was, she could have it. She handed her a Swiss Army Knife. Erin thought it was modified. Holtzmann revealed it was a normal one and no woman should walk around unarmed. Holtzmann handed her a Proton Grenade. She instructed her to throw it and it would send up a "little poof" only dangerous to ghosts. Erin armed and threw it. It exploded by some trash. Everyone was dazzled. Holtzmann corrected herself, it was a medium poof. Holtzmann handed the Ghost Chipper to Patty. She revealed its name was the Ghost Chipper and it used hollow-laser technology that sucked in the ghost and neutralized it. Patty told Holtzmann she truly scared her. Patty activated it. A trash can tipped over and the Chipper drew in the trash through it. The shredded trash exited the rear of the Chipper and went all over Erin and Abby. Abby wore the Proton Glove. Holtzmann explained the Proton Glove maximized flexibility during hand-to-specter combat. She instructed Abby to give it a punch because it was motion-activated. Abby gave it a try. The burst from the Proton Glove zig-zagged between the alley. It bounced off a blue dumpster towards them. They ducked. It took out a motor bike. It is launched straight up in the air then crashed into the ground. Abby declared that was awesome. Erin tried to high five Abby. Patty and Holtzmann shook. Abby pulled away and told her that would have been a deadly high five. Holtzmann declared that was a successful test. Bennie stepped outside and saw the wreckage then looked at them in dismay.

After Lynch's press briefing labeled the Ghostbusters as frauds, Erin slammed her head on the table but a beaker of Hydrochloric Acid dropped onto the floor, broke, and the acid hissed. Holtzmann was sad to see her favorite acid go. Kevin walked in to the lab area and offered to get it. Kevin asked them what that thing was that threw out that man out the window the other day. Holtzmann was dismayed by his question, told him it was a ghost, and asked him if he knew what their business was about. Kevin proposed a plan to sell the restaurant since they haven't had customers. He stepped forward right into the acid. Holtzmann told him it was Hydrochloric Acid then instructed him to get the baking soda. Kevin sprinkled the baking soda over the acid. She commended him. Kevin soon remarked he could not see. Holtzmann informed him that was the effects of the acid fumes. Abby told him to go in the back to the eyewash station. Kevin asked where that was. Abby told him to go back by the bathroom then go left until he hit something. They soon heard a thump then Kevin groaned.

They took note of all the recent ghost sightings and marked them down on a map then realized Ley Lines were involved. Holtzmann understood and emoted. Patty asked what it was. Holtzmann walked over and grabbed a "Ley Lines: of North America" book from a cardboard box while they explained it was a hidden network of energy lines that ran across the Earth. Holtzmann laid the book down, took her glasses off, and flipped through the pages. She smoothed a page down and placed Erin's map half on the book then slid it forward. She implored them to dismiss Ley Lines then patted the book. The two maps, the one Erin marked and the one in the book were identical. Abby admitted that it looked like it had some merit. Erin realized Rowan was using the devices to charge the Ley lines and create a vortex. Abby pointed out if he got one of his machines in intersection and it was big enough, he would be able to rip a hole right through the barrier. Holtzmann demonstrated with her hands how whatever was on one plane of existence would then crash down onto another plane of existence as a result of the machines then she smacked the center of Erin's big "X" on the map. Erin wondered what was at the intersection between 7th and 8th. She grabbed the laptop and typed. Holtzmann read aloud, it was the Mercado Hotel. Patty recognized the name. Patty revealed the Mercado had one of the weirdest histories of the buildings in New York. Holtzmann thought she meant it was a standard-issue haunted building. Patty explained its history extended before there was a building. All sorts of massacres happened at that spot. Patty mentioned the peaceful trade between the Lenape Indians and Captain Warren suddenly ended with everybody dying in an instant. Patty stopped and recognized Rowan in the employee photo. Abby rallied everyone to gear up for the Mercado. Holtzmann drove.

The Ghostbusters went down to the boiler room and confronted Rowan. He revealed his plan was to break the barrier between worlds then an army of the undead would return to pester the living. Erin didn't think "pester" sounded so bad. Rowan clarified they would pester the living with unspeakable pain and torment, children would be pestered limb from limb in front of their own parents, the parents would be pestered in half and pestered in half again then pestered into the ground until their bloody, pulpy bodies were nothing but meat. Erin admitted that was a different definition than what she was thinking. Holtzmann offered up the word "apocalypse." Abby to tried to appeal to him by listing the terrific things in the world but she could only think of soup. Rowan tried to continue on. Abby yelled at him to stop and informed him the police were already on their way and he was going to jail. Rowan told them goodbye then grabbed hold of two pylons and electrocuted himself to death then his body dropped to the floor face first. Holtzmann commented that was a weird move. Abby asked Holtzmann to shut the machine down. Holtzmann jogged over to where they found Rowan. The electricity powered down. The ghosts vanished from the mirrors. Erin asked if they were good. Holtzmann believed so, except for Rowan. She admitted it was never good to see the smart ones go bad.

Holtzmann found a copy of Ghosts from Our Past and swiped it before the police noticed it then presented it to Abby and Erin. They were mortified but oddly flattered he bought their book. Lynch, Hawkins, and Rorke thanked them for stopping Rowan but still staged a fake arrest. The Ghostbusters walked down the sidewalk away from E 45th Street. Abby declared it was mission accomplished and proposed getting some drinks to celebrate. Patty held out her right arm to Holtzmann for a high five. Holtzmann grabbed Patty's arm and kissed her hand instead. Patty pulled away. Blogger Chris Gethard caught to them and asked obnoxious questions, offended Erin, and got punched out. Erin was mortified the New York Post late edition covered in incident. Holtzmann placed the Ghost Chipper down and scooted into the booth from the other side. She asked Erin to guess whose desk she just set on fire. Holtzmann got no answer and presumed she would guess when she saw her desk later. Erin told her to just read it. Holtzmann saw an article about how a Midtown movie theater owner claimed a Basset Hound regularly attended matinees by himself. She was amused by the hound's ears. Erin clarified she meant the article about her. Holtzmann turned the pages. The article revealed cellphone video of the fight was uploaded to Youtube and Gethard later tweeted that he was "feeling fine with the help of an ice pack and a nice glass of Merlot" then he thanked his followers for their words of support. The article also mentioned the Ghostbusters were just in trouble two days ago when Martin Heiss was hospitalized after falling through a window in a freak accident. Holtzmann proclaimed the article was devastating. Erin sighed. Holtzmann noticed Erin was on TV, too. Fox 5 News played clips of Dean Harold Filmore and Dean Shanks commenting on Erin. Abby clicked the TV off in disgust. Patty advised Erin to shake it off and reminded her of the lives she helped save. Holtzmann recommended they leave and get something to eat then look for the Basset Hound. Erin was still down and went home to her apartment instead.

Holtzmann and Patty returned to headquarters with sandwiches. Patty called out to Abby to eat since her moods had been real bad. Holtzmann walked towards the restroom. She called out to Abby then sang to her to get her sandwich. She tapped the restroom door and was about to knock but it opened. Abby greeted Holtzmann by her first name. Holtzmann asked her if she was okay. Abby replied she was fine and walked to the lab. Holtzmann was puzzled. Abby picked up tubing from a pile, put it back down, and picked up a pipe. Holtzmann told her she got it at the dumpster the day before. She revealed she was going to use it to make a proton shotgun or just swing it around and break stuff. Abby attacked the Proton Packs mounted on the wall. Holtzmann dashed over and grabbed the pipe. Abby shoved Holtzmann across floor. She walked over and picked Holtzmann off the floor by her throat. The window was shattered as Abby walked Holtzmann through it and dangled her outside. Patty charged. Abby dropped Holtzmann but Patty shoved her to the ground and grabbed Holtzmann's right arm just in time. Abby leaped onto Patty's back but got shoved into the wall. Abby stood back up. Patty held her back by pressing against her head. Abby pushed her hand aside and ended up on her back on the window frame. Holtzmann pleaded for some help. Abby's head twisted around like in "Exorcist" and faced Holtzmann. Holtzmann and Patty naturally freaked out. Abby's head twisted back to its original position and said, "Boo." Patty screamed. Abby stood up. Patty referred to her as a hellion and tried to vanquish her. Abby stopped in mid-air then they tussled again. Patty pulled up Holtzmann back inside and all three fell to the floor. Rowan left after Patty slapped Abby but they watched as he possessed Kevin outside and drove off.

Holtzmann once again took the wheel and drove Abby and Patty to Times Square. They got stuck on West 38th. Holtzmann declared they hit an impasse. Abby elected to clear a path elsewhere but there were Sabrett Hot Dog Carts all over. Holtzmann remarked it looked like her kitchen. There was a green glow coming from the one on the left. They slowly approached. The lid popped open. Slimer roared and scarfed more hot dogs. They gasped. Abby asked what the hell that thing was. It flew towards them. They side stepped him and he flew right into the driver's seat of Ecto-1. The engine started and Slimer reversed out. Abby was annoyed at Holtzmann for leaving the keys in the car. He charged Ecto-1 towards them. Abby ordered everyone to light him up. Holtzmann interjected and revealed the equipment on the roof rack was basically a nuclear reactor. Patty cast her vote that they don't shoot at it. They gasped and jumped out of the way. Ecto-1 barreled past the carts. Abby realized they gave a ghost a nuke and proposed they should probably run.

The Ghostbusters ran past people and paused to look to West 38th Street and 6th Avenue. They saw a ghost balloon parade. One of the balloons doubled back and peered at them. Holtzmann admitted she just made eye contact. Abby asked if she meant with the balloon. Holtzmann confirmed and added she looked straight down the barrel. The balloons chuckled and started floating towards them. Abby guessed they looked like chew toys to him. They blasted the balloons and they popped one by one as they slowly drifted towards them. They popped and puttered away. The last one was of the Stay Puft Marshmallow Man. It landed on and smothered them against the street. It chuckled. Abby groaned. Patty pointed out how absurd it was. Abby stated she couldn't reach her trigger. Holtzmann told them it was exactly how she pictured her death. Erin found them and popped it with her Swiss Army Knife. Holtzmann yelled welcome back then asked if she was shouting. Erin confirmed. Holtzmann yelled the balloon popped her ear. Abby announced it was time to go save the city and get their terrible receptionist back.

Holtzmann reminded everyone they had Proton sidearms to use. Abby told everyone to power up. The Ghostbusters opened fire with their throwers on the ghosts that emerged from the P.K.E. mist. The Ring Leader growled. A ghost hurled a tomahawk. Patty yelled at Holtzmann to get down. Patty and Holtzmann landed on the street. The tomahawk struck the chest of another ghost. Abby wrangled it and hurled it into other ghosts. She called it a slap shot. Mayhem eyed Holtzmann. Patty holstered her thrower and got out the Ghost Chipper. Patty remarked it was chipping time and proclaimed he was getting what was coming to him for sitting on her. Mayhem was chipped. Erin sidestepped the remains that exited the Chipper. Holtzmann thanked Patty. A ghost shoved Patty into a van. The Ghost Chipper was stomped to pieces. Abby and Holtzmann chucked grenades at ghosts. The Ring Leader pointed and deeply growled. Ghosts charged out of the mist at Holtzmann. She holstered her Particle Thrower and twin Proton Pistols emerged from her pack. She licked one. Holtzmann took down several ghosts by herself. The Ring Leader had enough and advanced on her. She blasted it continuously with both pistols and dispersed it right before it could grab her. She released the pistols and they automatically went back into her pack like a seat belt being released. Holtzmann declared the ghost just got Holtzmanned.

The Ghostbusters stepped into the lobby of the Mercado Hotel. After sending a civilian named Frank, Rowan invited them to take a seat. Chairs glided to them. Holtzmann took him up on the offer. The chair was yanked away and she fell on her butt. Rowan laughed. Holtzmann admitted she appreciated the joke because it was a classic. Abby told Rowan it was time for him hop out out of Kevin's body. She admitted they liked him, despite his many, many frustrating quirks. Holtzmann added he just started figuring out the phones. Rowan eventually tired of Kevin and left his body. Abby ordered nobody to let Rowan get away. They traded insults with Rowan as they blasted at him. Patty shot the hotel up. Holtzmann reckoned she broke it. Rowan asked Abby what form she preferred he take. Patty took the lead and wanted something nice and cute, like a friendly little ghost. Rowan appeared as the Ghostbusters' logo and asked them if it's what she wanted. The No sign morphed into a tiny red bow tie and landed onto Rowan. His form became sinister and started expanding in size. They were sent flying outside by a flood of green energy and the shock wave knocked the police, agents, and soldiers on their backs.

Abby prioritized the need to reverse the portal but it required an insane amount of energy. Erin wondered what to do. Abby believed they just had to shoot directly in the portal with more power to cause a reverse reaction. Holtzmann suggested they cross the streams. Erin remembered that was the thing that was so powerful that would make all of their atoms implode. Holtzmann corrected her and thought it would be more violent than that. Abby believed they had an extremely good shot at pulling all the ionized ecto-matter back into the dimension of its origin by crossing their streams into the portal. Erin saw the pro was they saved the world but the con was they experienced the most painful death conceivable of all time. Abby admitted it was hard to shine that penny. Erin agreed to do it. They returned to the portal and crossed the streams into it. They fell on their backs from the recoil. Abby realized the portal was too strong and they didn't have enough power to reverse it. Ecto-1 returned again. Patty asked about the roof rack equipment. Holtzmann theorized if they could get the reactors super-critical inside the vortex, the beta radiation could reverse the polarity. Erin realized it would cause a total protonic reversal. Abby equated the plan to turning the portal into a giant ghost trap and called Patty a genius. Patty stated she was a Ghostbuster. Abby told everyone to focus on narrowing the car's path. They blasted one pole at time. Ecto-1 swerved away from each one. Holtzmann directed them to aim for the silver canisters. They side stepped Ecto-1 and fired. Ecto-1 launched in mid-air into the portal. They nailed the canisters as it descended into the Portal. The Portal turned red. All the ghosts around the city were pulled in by red streams of energy shooting out of the Portal. Rowan grabbed Abby as he was pulled into the portal.

Patty and Holtzmann watched as Erin dived into the portal. Patty and Holtzmann pulled on Erin's wire from outside the hotel. As Erin and Abby reached the red zone of the divide, their hair turned white. Patty and Holtzmann lost their balance. Abby and Erin emerged just as the portal closed and they burst through the doors. Holtzmann and Patty exclaimed. Patty noticed their hair was white. Erin looked at Abby's hair and vice versa. Erin asked what year it was. Holtzmann joked it was 2040 and the president was a plant. They fell for it. Holtzmann told them she was kidding. They realized they saved the world. Kevin joined in and ate a sub sandwich. Patty asked Kevin what his contribution was. Kevin claimed he did a lot and explained he walked over to the power box, pushed a bunch of buttons, everything got sucked into the portal, then it closed up. Holtzmann told him the two things were unrelated.

The Ghostbusters waited for Lynch in a Jacob Wirth Co. Restaurant. Erin fidgeted with her hair, nervous about the dye job. Holtzmann quipped she would talk to her at an AA meeting. Patty snickered and drank. Erin admitted she thought the color was Garfield like the cat but it was the president from the Dead Presidents Color Collection. Holtzmann warned her to stay away from Taft because that was her mother's color and she didn't want to see that on anyone's head. Holtzmann decided to make a toast and tapped her glass with a utensil. The others were concerned. Holtzmann talked about how physics was the study of the movement of bodies in space, and it can unlock the mysteries of the universe. But it cannot answer the essential question of what is our purpose here. And, to her, the purpose of life is to love. And to love is what they have shown her. She didn't think that she would ever really have a friend until she met Abby, and then she felt like she had a family of her own. She ended telling them she loved them and thanked them. Holtzmann clinked glass to glass with Patty then Abby then Erin and sat. Abby was surprised and thanked her back. Erin, Abby, and Patty clinked drinks. Patty was moved. Holtzmann cleared her throat loudly. Lynch pulled out the fifth chair and apologized for being late. She thanked them for their discretion even though it was not working at all then chuckled and revealed the Mayor wanted them to continue to study the paranormal, fully funded, so the city can be better prepared just in case of another event. She emphasized they can have anything at all. Erin got an idea to ask for the Firehouse.

The Ghostbusters walked to the Firehouse. Holtzmann claimed the second floor for herself. Patty disputed that she can claim a whole floor. Holtzmann retorted she just did. Patty ran after Holtzmann. She began work on equipment aimed at disposal and containment. Some time later, Abby and Erin approached the lab and got Holtzmann's attention. She turned around to them. Erin asked how things were going. Holtzmann told them it was going really good and she was working on some kind of next-level stuff. Holtzmann pushed a button on her Keysight FieldFox Microwave Analyzer. The Ghost Transporter, a giant device resembling a bear trap, activated. It clamped shut then released. Erin gasped in shock. Abby was impressed. Erin asked what it was for. Holtzmann stated it caught ghosts and it transported them somewhere else. She admitted she doesn't know where but had a feeling it was Michigan then apologized out loud to the city of Lansing. Abby asked about the Containment Unit. Holtzmann replied that was going real smooth but warned them to not be in the room with it for more than an hour at a time, because she was thinking there may be a lot of hair loss. Dr. Rebecca Gorin walked around the Containment Unit, assessing it and not paying them any attention. Erin tried to greet Gorin. Holtzmann kicked herself and introduced Gorin as her mentor. Gorin commented it was reckless and all someone has to do was sneeze too hard and everyone in this building would disintegrate. Holtzmann admits it was completely unstable. Holtzmann laughed as she pats Rebecca's right shoulder with her green lab gloves. Gorin addressed a safety light and asks if it was needed. Holtzmann remarked safety lights were for dudes. Gorin was amused. Holtzmann chuckled and high-fived Gorin. Gorin shook her head and stated she hated doing that. Patty came down from the stairs and told everyone to come up to the roof. Buildings across Manhattan were lit up thanking the Ghostbusters. One read, "NY S2 GB" while another read, "I love GB", and another read, "NY Loves Ghostbusters." Patty was happy some people actually knew what they did. Holtzmann placed her arm around Abby. Abby grabbed her hand. Erin and Patty linked up to them.

Some time later, Erin and Holtzmann inspected a new device in the back while Abby tinkered with something and Patty, headphones on, listened to a recording. The device Erin was inspecting clanked. Holtzmann called it the Nutcracker. Erin assumed it crushed ghosts. Holtzmann quipped it was for walnuts. It clanked again. Erin nodded and commented "Smart." Patty revealed she heard something really weird and asked them what "Zuul" was. Everyone was silent. Erin and Abby couldn't think of anything and both shook their heads. Holtzmann contributed a new section to Erin and Abby's revised edition of Ghosts From Our Past: Both Literally & Figuratively: The Study of the Paranormal. She wrote about the basic equipment the Ghostbuster used, like the Proton Pack, P.K.E. Meter, and Trap.[14]

Secondary CanonEdit

IDW ComicsEdit

Growing up, Jillian Holtzmann didn't identify with people and faked her way through social interactions. She took comfort in being able to make sense of what she built and fixed. That was "home" to her.[15] A teenage Holtzmann decided to use St. Paul's Chapel as the site to conduct her first weapons test despite others urging her not to.[16] She chose the night of Friday the 13th.[17] Holtzmann managed to push her hefty weapon and its cart upstairs into a room. She realized she needed to either start going to a gym or develop a lightweight polymer substitute. She started the weapon but something went wrong. She ran for it and yelled out for anyone to run for their lives. Abby, Erin, Patty, and Holtzmann fled to the cemetery and hid behind headstones. The chapel partially exploded. They noticed each other and ran away in opposite directions. In the end, Holtzmann learned so much and felt the incident was worth it in the end. As part of an experiment at Higgins, Holtzmann tried to implant a memory into Abby. As a result, Abby developed a strong love for soup.[18][19] Holtzmann later met, Erin, Kevin, and Patty. They all got her and it felt like a family. Her life changed.

Patty and Holtzmann went to Queens in search of a ghost to trap for study. After spending a great deal of time there, they encountered Ralph and gave chase. Unaware of a portal that was briefly open in a park, they caught up to the ghost and fired. Patty admonished Holtzmann for blowing up another car. Holtzmann insisted the ghost used its psychic powers to do it. The ghost turned around and charged them. Holtzmann was over it and pulled out one of her Proton Pistols then blew up the ghost. Patty was not too pleased to be drenched in ectoplasm again. Patty called up Abby and informed them they came up short again. Abby told Patty to inform Holtzmann she couldn't blow up anymore ghosts until they trapped at least a Class 5. Patty also informed her Holtzmann blew up more cars. Abby also placed a moratorium on blowing up cars since they were being threatened with the costs.

Abby, Holtzmann, and Patty responded to a call from the Stryker Beach Golf Course in Brooklyn. Holtzmann couldn't resist and asked who had a problem with their balls. Abby chided her but Holtzmann pointed out the expression on a patron's face. She proposed a $20 bet that she could make him fall over. An employee dissuaded her. Holtzmann changed the bet to not make him fall over. He directed them to the 13th green, where the ghost was sighted. Holtzmann didn't like its face and neutralized the ghost with the Ghost Chipper. Abby was dismayed. Holtzmann insisted the ghost's P.K.E. readings were too skewed to be a decent test subject. She declared it was time to head to Queens and marched off. Upon returning to headquarters, Abby fretted about building an observation tank. Holtzmann told her to relax and posited she had maybe three ideas about building one.

A couple weeks later, Holtzmann was woken up in the afternoon by her roommates, Cal and Jim. She emerged from her bedroom half asleep and poured some coffee. She was jolted awake upon hearing the Ghostbusters were on the scene. She ordered Cal to turn up the sound on the news. She watched as Peter Venkman, Winston Zeddemore, and Ray Stantz were interviewed about the appearance of a second Statue of Liberty next to the other. Holtzmann quickly suited up and took off. Cal asked her to pick up milk on the way home but she replied she couldn't because of the metaphysical crisis at hand then suggested Jim handle it since he was good at small tasks. Jim declared she was the worst roommate ever. Cal reminded him she did save the world once and that should buy her some leeway. Jim admitted he would if she didn't pull that sort of excuse on his days off. Holtzmann found the others standing outside the Firehouse. Patty suggested everything was happening like the Star Trek episode that involved the Mirror Universe. Holtzmann reminded her that was just a TV show. They discovered the layout of the interior and its contents were different. Holtzmann scanned the Vigo portrait while she ate some Pringles. They were reunited with Kevin Beckman, who was upstairs with Egon Spengler. Holtzmann raced up the stairs, grabbed Egon by his tie, and asked about his hair-do.

Holtzmann looked at the Paranormal Containment Research Tank and realized it was using ionized glass to keep Slimer inside. She figured she never thought of it because it was a simple design. Abby mistook Slimer as the one they encountered in Times Square but Holtzmann reminded her they blew that one up. Abby wondered if they were in "ghost hell" but Holtzmann pointed out that would just be Hell. Abby told her to be quiet. Holtzmann volunteered to wear the Aura Video-Analyzer helmet and studied the Giga meter in the meantime. They showed them the Interspatial Teleportation Unit in the basement. Holtzmann looked at the Containment Unit and asked who was overcompensating for what. She turned to Ray. Peter implored him to tell her. The teleportation unit was turned on. Holtzmann stuck her hand in but it emerged from the portal well above her arm. That was enough for Egon to be convinced their dimensions were overlapping. Abby wanted more proof. Egon opened a portal to the dimension occupied by the Ghostbusters they helped with against Proteus. Holtzmann stuck her head through and saw versions of Peter Venkman and Egon Spengler talking about stolen cheese. Holtzmann told Egon to lose the rat-tail then pulled back. She noticed the same No Ghost logo, too. Holtzmann declared she wanted a magic doorway, too. Ray started to explain how they seeded the Ghostbusters concept into the subconscious of the Multiverse when they crossed the streams on Gozer's portal. Holtzmann remarked they weren't shy with each other. Ray clarified he meant proton streams. Patty wondered if her team was going to end up fighting Gozer, too, after she remembering hearing "Zuul" during EVP duty. Kylie Griffin speculated they would only be fighting a weaker echo but Holtzmann pinched her cheek and told her the adults were speaking. As they walked back upstairs, Ray stated they were going to need the "usual samples" from them. Holtzmann didn't think that line possibly worked then she answered the front desk's phone and took some information down. Abby didn't think it was the time for them to be working but Holtzmann wanted to zap something and clear her head. She asked who else was up for a boat ride.

Holtzmann was beside herself and was in awe of Marine Ecto-8 and all the equipment the Ghostbusters had. She picked up the Proton Bazooka and asked what the yield was then rescinded on account of wanting to be surprised. Peter Venkman asked Erin and Patty if they ever tried Adderall with her. They tried it to see if it would help with her focus but revealed she put them in a Pez dispenser and popped them like candy but it did little to slow her down. After Erin had a panic attack about Winston Zeddemore looking like Uncle Bill, Peter Venkman looking like Martin Heiss, and Ray Stantz looking like the Cabbie, Holtzmann slapped her. After they arrived on Ellis Island, Holtzmann started dispersing ghosts with her Proton Pistols. Ray grabbed her right arm and told her to stop. He cited the First Law of Thermodynamics and warned her the P.K.E. would reintegrate quickly in the presence of the tear. Holtzmann told him he was worrying too much. There was a boom. Holtzmann told him to not say I told you so. The dispersed ghosts formed into a single powerful entity and attacked them. Holtzmann was annoyed and recalled it never happened when they shredded ghosts in the past. Erin theorized sealing Rowan's breach sucked up a lot of the psychokinetic matter. Holtzmann was more annoyed. She opened the floor to suggestions since they couldn't trap or blow it up. Erin suggested an explosion and ran off with Ray. Patty and Holtzmann got into a debate about what a Kraken looked in relation to the entity. Holtzmann tossed a Proton Grenade at it. Patty brought up the Kraken from "Clash of the Titans" had legs. Holtzmann noted Harry Hausen wasn't worried about accuracy. She dodged a chunk of earth thrown by the entity. Erin weakened the entity with a blast from the Proton Bazooka then Ray captured it with a Megatrap he rigged to explode then swung it from Ecto-4 into the seal. The concentrated explosion sealed the breach. Holtzmann was fuming. She told Erin there would be reprisals for her violating the sacred rules of dibs by using the bazooka before her. She turned to Ray, in a tree, and demanded to know where he was hiding the mini-helicopter. She then asked why he said explosions weren't the answer if an explosion was the solution. Ray corrected her that a ghost would reintegrate unless the P.K.E. was dealt with in some way and an explosion was often the answer in ghostbusting as well as in life. Holtzmann was still mad about the bazooka and helicopter.

While Walter Peck was in the garage bay with Janine demanding a comprehensive update from a Ghostbuster, Holtzmann couldn't help herself. She appeared from behind a column and stated they were on top of everything then reminded him to tip the server. Peck mistook her for one of the fantasy campers from Ghostbusters 101 and asked Janine if it was the time to let them roam free. Holtzmann stated she was from another dimension and could steal a soul with a kiss. She grabbed Peck and told him to pucker up. Peck flinched and told Janine to keep her away from him until things were resolved and to be kept in the loop then left. Holtzmann joked he had nothing to worry about since redheads didn't have souls. Janine told her to watch it but mused she would fit in with that attitude then told her about a call that just came in from the Bronx. On the drive to the Bronx, Holtzmann modified several Traps to open wirelessly through her Upper Arm Remote Trigger. She still couldn't believed they used wired manual traps. Peter couldn't believe she still had energy after a dozen busts in two days. She joked her secret was caffeinated suppositories and patches.

After they parked at Woodlawn Cemetery, Holtzmann skipped ahead of everyone with the modified Traps. She hid them amid graves then found Peter, Winston, and Patty struggling to rein in the Moby Dick Ghost. She fired a Proton Pistol at one of its eyes and proceeded to antagonize it further by whistling and calling it Willy. The ghost took the bait and chased after her. She managed to run back to the spot and opened the Traps. They pulled the ghost apart and trapped it. Upon returning to the Firehouse, Holtzmann flipped out at the sight of the Containment Unit being taken apart. Ray explained it was Abby's idea to repurpose it for their Ultimate Mobile Trap prototype and promised to rebuild it after the incident was resolved. She was eager to know the entirety of the plan. Abby, Holtzmann, and Kylie put the finishing touches on the Ultimate Mobile Trap just as Special Agent Melanie Ortiz arrived. Melanie mistook Holtzmann for her dimensional counterpart in the FBI. Abby was amused at least one of them had a doppelganger. Holtzmann told her she was very mistaken. Melanie remembered Janine told her about people from an alternate universe. Holtzmann asked if her other self was into alien abduction and had a red-headed partner. Melanie hinted she was less "alien abduction" and more "damn fine cup of coffee." Holtzmann declared she needed to meet her then explained some of what was going on with the overlapped dimensions. She was elated to hear Kylie had programmed the horn to sound like Debarge like she asked. Melanie asked what was going on with the Ley Lines, annoying blondes, and duplicate monuments. Holtzmann retorted she wasn't annoying then suddenly popped up between them. Melanie dialed Agent Holtzmann and give the phone to her. Abby introduced herself to Melanie and told her not to worry about Holtzmann since she couldn't resist trying to annoy a federal agent.

Kylie estimated it was time to depart. Abby stated the trap was a two-seater and Holtzmann stated they were the professionals. Holtzmann promised herself she would visit her if she was ever in her dimension again then tossed the phone back to Melanie. Kylie concluded she was worse than Ron Alexander. Abby and Holtzmann stopped in Duffy Square. Abby triggered the trap and the ghost soon manifested from a breach in the sky. After the ghost was trapped, Holtzmann declared they were two for two. The breach remained so the Ghostbusters had little choice but to Cross the Streams on the breach to seal it and separate their dimensions. Holtzmann felt like she was being pulled in a million directions and admitted she was panicking and it hurt. Two weeks later, Peter and Ray visited their dimension to rebuild their Containment Unit as promised. Holtzmann asked if he was going to build them a teleportation unit next. She believed she could build one herself and realized she had some of Ray's memories, including schematics and what it was like to make out with a ghost. Ray inquired about what her actual doctorate was in but Holtzmann asked him to pretend they never talked about it. She introduced Rebecca Gorin and Peter Venkman to each other. Holtzmann and Special Agent Holtzmann became quite close ever since. The Ghostbusters felt their friendship could open new doors in the field of psychology. Peter took the initiative and chose a book title.[20]

Holtzmann was inspired and added some of her tweaks to the design of the Trap the other Ghostbusters used.[21] She couldn't wait to employ the newly modified trap at the at the Yorkville Brownstone case. Abby tried to downplay the situation and stated they did it 100 times before. Holtzmann pointed out it was their 82nd case. Abby retorted she was rounding up. The Ghostbusters were surprised by the sudden manifestation of the Timothy Ghost. Erin and Abby pointed out it was just a child. Patty got wound up and went on a stir about children in horror movies. Erin noticed the ghost had a hoop and stick. Holtzmann added it kept calling them "Mommy." Before they opened fire on it, Holtzmann antagonized it by stating its mom was definitely dead. Timothy transmogrified and attacked them. They took cover by some furniture and used the "Hi-Lo" maneuver to trap the ghost. Holtzmann enjoyed it then revealed she had something cooking back at the Firehouse lab and they had to get back by 5 pm or things would get messy.

Erin asked Kevin to order the usual from Zhu's but resigned herself to the inevitable and the food would never show up like Holtzmann pointed out. Holtzmann placed a diode on Erin's forehead for an experiment while she asked where Abby went. Patty suddenly burst in and shared her discovery of an entry on the brownstone. Patty read out loud a Doctor Kruger lived there in the 1900s and conducted fear experiments. Holtzmann found the name very tacky and too on the nose. She wanted to put a diode on Patty's head, too, but she declined. Holtzmann promised it would only hurt for a second. Patty held her back with one hand then continued with reading the entry. Holtzmann jumped on her back but Patty continued to resist. They realized Abby was possessed again. Holtzmann predicted Abby would be pissed and wondered if there was a susceptibility after someone was possessed for the first time. Erin and Patty yelled at her. Holtzmann reminded herself to conduct a study later then hopped across a table and grabbed her De-Possessor. She went on explaining how she was inspired by Abby's first possession and designed it to reach in and separate the two essences. Holtzmann warned she had to be careful to pull out the ghost but they yelled at her to just use it. Kruger was pulled out of Abby and Holtzmann declared it was all in the wrist. Kruger attacked and drained them of energy. They fell to the floor. Holtzmann felt oddly terrified, too. Abby implored her to use the Ghost Zamboni and allowed her to skip safety testing. Holtzmann was stunned and quickly pulled off the tarp. Kruger resisted its pull, burst through the upper floors, and escaped into the city. They ran to the roof and saw him at the Empire State Building. Holtzmann declared she was going to need so many new weapons to take out Kruger.

Holtzmann liked Patty's idea of a making a new weapon but she wanted more field data from Kruger in order to build something that would be effective. Even though they would get their butts kicked again. Holtzmann tried putting her spin on the St. Crispin's Day Speech but Patty wasn't having any of it. The Ghostbusters attacked Kruger at full power but he resisted. Holtzmann noticed there were multiple streams of an unidentified energy powering him up. Kruger sent their consciousnesses into the Nightmare-Scape. Holtzmann found herself in a office cubicle in a room adorned with signs repeating the message of "Obey," "Consume," "Reproduce," and "Conform." The rows of cubicles seemed endless. A robot manager droned on about TPS reports. Holtzmann jumped out of the cubicle, went back for a printer, then ran to the unisex restroom. She attempted to disassemble the printer and invent something but her hands and fingers suddenly went limp, flat, and curled, unable to create anymore. Holtzmann's fears were of corporate America, conforming, and not being able to create.[22]

40 minutes after their defeat at the hands of Kruger, Erin broke the silence inside Betty's Diner and spoke up but Patty got irritated and confirmed it was too soon. Erin agreed what they experienced was awful but refused to give up and took solace they got away. Abby disagreed and pointed out they didn't know anything. Erin was sure they would figure it out. Holtzmann clarified Kruger let them go because they had nothing to offer and were unimpressive. She left the diner sullen. Erin found her in the alley with her Proton Pack and for once, she didn't want to talk. Erin went first and admitted she was more afraid to see Holtzmann unwilling to overcome a challenge than her fear of bees. Holtzmann started laughing. Patty and Abby joined them. Holtzmann continued to laugh at Erin's expense. She clarified she was laughing at her fear, not her, but the others weren't catching on. Holtzmann clarified someone's fear was dumb to someone else and the reason they lost was the specificity. She theorized it could free them, too, and was ready to get back to work. The others were glad she was back. They drove back to the Firehouse. Kevin Beckman was used as a test subject after he promised to be very quiet. She bypassed aspects of the device so Kevin wouldn't wet himself. The Dream Machine gave mixed results but through a freak discovery, Holtzmann learned it made perfect scrambled eggs. She admitted it still had a long way to go before it could be of any help.

Patty couldn't believe Holtzmann considered Erin and Abby screaming a partial success and called her definitions weird. Holtzmann also used the Dream Machine at the same time to make scrambled eggs for Erin and Abby. Kevin brought her a record and frisbee instead of plates. Patty believed he wasn't even trying but Holtzmann classified it as creative problem-solving. She admitted she found it inspiring and wanted to study him the next time they had a break. Holtzmann was at an impasse. She could create a dream merge but couldn't control it. Holtzmann wanted to implant memories but nobody would agree to it. After several hours, they made little progress. Abby suggested more power but Holtzmann cited she would need a Neutron Bomb as a power source and recalled a man she knew in Brighton Beach that could supply her. Erin struck down the idea. Holtzmann reiterated without any leads from the journal, she couldn't figure out a way to stop Kruger from putting them back in the Nightmare-Scape so they needed a way to control their dreams and hide. Holtzmann further explained a common memory that was buried and attached with guilt or shame would be sufficient. Since there wasn't one, Holtzmann circled back to a memory implant. She was turned down again. It reminded her of her first weapons test that partially blew up St. Paul's. They realized they were all at the chapel on the same night. Holtzmann couldn't believe the odds of that happening and was glad she didn't accidentally kill them all. 90 minutes later, they departed for the Empire State Building again. Before Erin could debate semantics with Abby, Holtzmann declared it was time.

Holtzmann ordered everyone to activate the neural connections on their Dream Machine head bands and reminded them not to forget the plan. In the Nightmare-Scape, Holtzmann plummeted down a black void. She reassured herself the plan worked. Holtzmann went on a little detour and arrived late at the shared memory of St. Paul's Chapel. She quoted "Die Hard" then joined the others in blasting Kruger. They were blown back to the real world then Kevin captured Kruger. Holtzmann admitted she was starving and was craving more of the nightmare-induced scrambled eggs. Erin and Patty turned her down in unison. Holtzmann pointed out they were so good. Abby admitted she was right. Holtzmann declared nightmare science eggs for everyone.

Holtzmann helped trap all of Connla's Army on Liberty Island in the prime dimension weeks away from Halloween. Ron Alexander was jealous of Egon's Remote Portal Access Band and wanted the technology. Holtzmann cited she had first dibs on it. Two days later, Holtzmann met with Ron at a Pequod's and agreed to his proposal to team up and build their own teleportation unit. They agreed they wanted their own just enough to work together. Holtzmann saw it as an opportunity to blow the doors off even the presumption of human limitations. With the teleportation unit, she could go everywhere and discover everything.[23] They shook on it and she wanted to get down to what exactly they would need to build one. She assumed coffee was on him and ordered a quad-shot. Ron still had his key to the apartment owned by his friend's uncle and used the space for the construction of his and Holtzmann's Remote Access Teleportation Unit. However, it wasn't exactly like the Ghostbusters' version. Unable to duplicate an autonomous trans-dimensional portal, they essentially built a larger version of a Remote Portal Access Band they stole and piggybacked off the original unit.[24] Holtzmann claimed she even figured out how to make the interdimensional transition smoother and prevent an open portal from attracting ghosts.[25][26] Jimmy was annoyed Ron didn't even give him a head's up he was in town. Ron filled in Jimmy on how the Ghostbusters came to have teleportation technology but Jimmy suspected he stole something and was back to puttering about in his uncle's apartment. Ron introduced Jimmy to Holtzmann. Holtzmann explained she came from beyond. Jimmy was naturally confused. Holtzmann confirmed she was a woman with several degrees, and only two were made up. Ron informed him she was a Ghostbuster from another dimension. Jimmy was aghast she probably had a God complex too. They proceeded to test their unit. It was a success but they were unaware the Ghostbusters were conducting an experiment observing the inside of the Containment Unit. Ron and Holtzmann's unit piggybacked off the original in the Firehouse basement and thus, activated it as well. Peter deposited a ghost at the same time and inadvertently set off a chain reaction.

Ron and Holtzmann went to Tip-Top for lunch. They ordered and sat at a table outside the cafe. Holtzmann noticed weird readings on the prime universe's P.K.E. Meter and her P.K.E. Meter that weren't ghost-related. Ron could care less but he soon was hailed on the walkie talkie by Jimmy, who alerted him the teleportation unit was acting weird. Ron and Holtzmann bolted and teleported back to the apartment. The waiter returned to an empty table and swore. They watched as their invention generated several portals at once. Holtzmann referred to it as a full nine on the Sanchez Scale. She knew the unit lacked the power to make so many at once and threw a big switch but nothing happened. Ron pulled the plug on the unit and turned it off. He guessed Holtzmann turned off the refrigerator instead then insisted they could fix the glitch. Jimmy prayed.

Ron and Holtzmann were reprimanded, for their part in the explosion, by Egon, Ray, and Winston on the third floor. Holtzmann emphatically apologized but Ron told her to speak for herself. Ray admitted he understood their drive but they stole and reverse-engineered the technology then failed to check if their experiment would be compromised by any number of outside factors. Ron tried to claim he was forced to make matters into his own hands because Ray and Egon were never going to share the dimensional technology and pinned the blame on them. Winston ran up to Ron, grabbed him by the collar, and encouraged him to repeat himself. Holtzmann asked him to stop. Ron sarcastically chimed in. Winston let go and asked if she was going to claim it was all for science. Holtzmann admitted she would have abused the chance to travel the multiverse but revealed her real reason was to find more people she could identify with and make her "family" bigger. Ron asked Winston if he was buying it and if so, claimed that his reason, too. Winston told Ron to shut up.

Ray inspected the Containment Unit console but Egon discovered several major entities were missing from it. Suddenly, the unit opened and Gareth Dibello escaped. Holtzmann ran to a gurney where a sole Proton Pack lay but Dibello lifted the pack and fired it. Dibello manifested and grabbed Holtzmann. Ron recognized him and promised Holtzmann they would avenge her death. The Interspatial Teleportation Unit activated and several miniature portals were generated. Egon thought it was Ron's doing but he feigned innocence and believed their technology had a glitch. Dibello flew into one of the portals with Holtzmann but she became stuck halfway through. Ray implied things would get "real messy" for her if the portal closed. Holtzmann implored them to pull harder. Egon and Ray pulled her back into the basement with part of Dibello's arm. Dibello became agitated and charged but the portal closed, leaving him in a parallel dimension. Holtzmann was unaware and kept screaming until Ray informed her Dibello was gone. She told them not to tell her teammates what happened because she had a reputation to maintain. Egon stopped Ron from finishing his sentence and asked Ray to check the records with him. The missing entities took portals like Dibello did to a parallel dimension. Two days later, teams of Ghostbusters, from both the prime dimension and beyond, gathered at the Warehouse. Egon opened up the floor to questions and Holtzmann raised her hand immediately.

A P.K.E. spike near the George Washington Bridge went unnoticed and a Doom Ghost manifested then enveloped the area in a purple fog. Special Agent Ortiz was notified and she asked for volunteers to help her. Holtzmann enthusiastically raised her hand and added she already had a grasp on the dimensional technology Ray and Egon were going to talk about. Peter wondered if someone dumped an upper in her coffee. Winston remarked she was guilty about the accident. Melanie, Winston, Holtzmann, Rookie, Dani Shpak, and Lou Kamaka drove to Fort Washington Park. Holtzmann left her headset on channel one and the Warehouse radio picked her up and Kevin Tanaka listened to everything, even her singing. Dani picked up two readings with Holtzmann's P.K.E. Meter. Rookie verified with his meter. Holtzmann speculated there was a "turf war" going on and suggested splitting up. She chose Lou and Dani for her team. She wanted to go west but Lou pointed out west would take them right into the Hudson River. Holtzmann admitted she liked Lou and congratulated her for passing the test. Melanie ordered everyone to stay in contact but Holtzmann made light of it. Rookie asked where Holtzmann was from. Winston wanted to say Mars but he only said the jury was still out. Holtzmann started spouting Law of Attraction rhetoric about how her vibrational energy was strong and she was pulling all the desired outcomes her way. Lou and Dani weren't supportive. Holtzann claimed it was parapsychology and was the first to sight the ghost. She claimed she was going to write a paper about it then fired but the ghost receded and the Proton Stream passed harmlessly through a hole in the fog. Lou and Dani found Holtzmann but panicked and Lou asked where the ghost was. Holtzmann yelled back they had equipment to track it themselves. The ghost formed tentacles and held Dani and Lou in midair. Holtzmann attacked it with the Proton Glove but it vanished again. Dani checked the meter again, saw the ghost was still present, and thought the P.KE. Meter was wonky. Holtzmann took offense. She hugged the P.K.E. Meter and insisted it was never wonky. She looked at the screen and changed her mind. The ghost whacked them with a tentacle soon after. Melanie, Rookie, and Winston provided cover fire but the ghost vanished again. Holtzmann realized the fog was the ghost and broke into the Lighthouse. She activated the searchlight and fog horn. Holtzmann's theory was correct and the ghost revealed its true form after its senses were rattled. They soon trapped it.

A field team consisting of Peter Venkman, Special Agent Melanie Ortiz, Bridget Gibbons of Dimension 50-S, Jillian Holtzmann of Dimension 80-C, Roland Jackson of Dimension 68-E, and Egon Spengler of Dimension 68-R arrived in a Comic Strip Dimension. Holtzmann panicked about the teams being shuffled around and wondered if they absorbed their teammates like evil twins in a womb. She tried to talking to hers. Egon 68-R found that unlikely and pointed out there were no ill effects physically but admitted the shuffle was something to be concerned about. He and Roland checked their meters. Peter sent a message back to the prime dimension to inform the team there of what happened. Roland picked up a trace of a Class 7 on his P.K.E. Meter. Egon 68-R concurred. Melanie reminded them they weren't after a Class 7 and they didn't have the firepower to fight one. Egon 68-R decided to err on the side of caution and made a note of the signature for further monitoring. Holtzmann grabbed Bridget and declared she came around to being careful. She was eager to find the missing ghost. Melanie remarked she got stranger. Peter pointed out she built something that almost killed him and it was part of a guilt-based mania. Melanie didn't buy her as the guilty type. Peter stated she wore her heart on her sleeve and those types got around to guilt eventually. Roland eventually locked onto the right signal and announced the ghost was close by. Peter feigned relief they wouldn't break into another wrong house. Holtzmann remembered the poor cat they encountered. Egon 68-R noted they weren't told what the ghost looked like. Roland registered a spike and ran off with Bridget. They stopped outside of a typical looking suburban home. He confirmed a positive match coming from inside the house. Holtzmann wanted to play if safe for once and go in first while the others waited outside just in case the ghost tried to escape. Melanie suggested they all stay together since only Peter had a Remote Portal Access Band to summon a portal home. She kicked the door in after a three count. Peter recognized the interior as the manifestation of Wander Hills Orphanage and realized they were after Ellen Gold.

Holtzmann found it freaky it was sunny and cheery outside but it looked stormy and gloomy from inside. Peter told the others what he knew about the orphanage. Melanie teased him for pretending he didn't. Peter claimed he was known to lie. Ellen Gold called him naughty but called out Holtzmann for being the naughtiest among them. Holtzmann was freaked out and blasted at Ellen with her Proton Pistols. Ellen dodged and started throwing children around. Two wrapped around Holtzmann and immobilized her but the pistol kept firing wildly. Bridget ducked and yelled at her to stop shooting so she could get close enough to use a Trap-Gate. Ellen grabbed Holtzmann and thought about punishing her. Ellen told Holtzmann she was very naughty and didn't care about who she hurt. Melanie couldn't get a clear shot and called out for options. Bridget asked if it was a "needs of the many" situation and Roland got too literal, explaining they couldn't map the consciousness like in "Wrath of Khan". Bridget called him a nerd. Egon 68-R came up with a strategy to blast the orphanage at a new frequency and power setting based on Ellen's P.K.E. signature since she shared it with her construct. Ellen felt it and fled upstairs with Holtzmann. Peter went after them with his own plan. Egon 68-R and Melanie felt uneasy about that. Peter found them in the kitchen, re-introduced himself, and asked for Holtzmann's release since he was naughtier than her. Like "catch and release." Holtzmann didn't think she would know what that was since she predated it. She covered Holtzmann's mouth then reacted to the orphanage being blasted. Peter recalled the others were still blasting up the house. She vowed she would endure and punish. Peter noted she was more talkative than their last encounter and proposed they talk. Holtzmann mumbled something in protest. He told her to relax because it was in his wheelhouse since Ellen used to see a shrink. She mumbled something again. Peter pointed out it wasn't like he would have to prescribe anything and boasted he exorcised himself before.

Ellen deemed Holtzmann guilty. Peter admitted she felt that way and was about as good as hiding it as a puppy but contended that things happen and punishment wouldn't prevent it. He argued it made the situation worse and taught people to associate pain with guilt then a psychopath gets made. Ellen repeated Holtzmann was chaotic. Peter retorted there were pills for that. The others blasted the house again and Ellen recoiled. They apologized for taking out a whole wall. Peter pointed out forgiveness was an important concept in self-healing. He forgave Holtzmann for hurting him. Ellen stated she had to learn. Peter believed she did already and was very sorry, and even got a whole mess of gray hair over it. Holtzmann mumbled something. Peter repeated he forgave her. Ellen released Holtzmann and threw her at him but she didn't forgive him for hurting her in her house. Peter held up his pedal and trapped Ellen. Wander Hills vanished and the team found themselves on an open lot. Roland asked if that was it. Holtzmann confirmed it was then asked Peter why he didn't do so sooner. Peter asserted it was better to take things slow when dealing with a ghost with a bad attitude. He also told her she was welcome for the save.

The field teams were whisked away by Tiamat to the Collectors' Limbo. Rather than serve her, they fought back. Tiamat broke through 23 streams. Holtzmann stated she didn't like her. Winston asked Holtzmann for her Proton Glove then told her to tell everyone with a functioning Trap-Gate to switch on the random destination toggle and stand by. She asked how he was planning to distract Tiamat. Winston charged and socked Tiamat with the Proton Glove. Seven Trap-Gates were opened and siphoned off Tiamat's P.K.E. to random dimensions then she was trapped. Back in the prime dimension, the Containment Unit was still unstable and was about to blow up. Jenny Moran sacrificed herself and went into the unit to stabilize it. Overcome with anger, Ray shot the teleportation unit. Holtzmann objected but Peter asked if she heard what just happened then reckoned Egon could fix it in a couple of hours. Egon claimed less. Holtzmann rescinded her panic then reminded Ray about the Containment TV Monitor he and Egon were working on.

After a day's worth of work, Egon, Ray, Egon 68-R, and Holtzmann of 80-C finished work on the Containment TV Monitor. Once the grid was stable and the monitor was ready, it was turned on. It worked and Ray inputted Jenny's P.K.E. signature. Jenny was found but a Mail Fraud Ghost charged her. Ray was aghast but Holtzmann told him to slow down. Jenny punched out the ghost. Holtzmann declared they were locked in there with her. Ray was relieved and hugged everyone at once. Ray vowed to make sure Jenny's promise they would see each other again would come true. Holtzmann was eager to head to her home dimension and getting working. Before Holtzmann left, Egon asked for her thoughts on a new application to old research of his. Holtzmann read his strip of paper but it made no sense. Ray inquired what that was. In reality, it was Egon's subliminal messaging code. He reworked it to interrupt any memory of the transdimensional technology. Ray asked if there were any side effects. Holtzmann was confused why the Chicken Dance was suddenly stuck in her head. Egon didn't think there were any side effects as far as he knew and planned to show it to Ron next.

You imagine her room is just this enormous pile of clothes she's found in dumpsters and Goodwill and bought at garage sales. The glasses, I liked the idea of her wearing glasses and Kate liked the idea of having something to play with. When those goggles were brought out that was a home run. She goes through a few different eyewear looks, but that one in the trailer is my favourite look of hers."
