Chapter 04 explores some of the history of Summerville.


Listed as they appear in film.



"Muddy Water" played inside Wertheimer's Hardware. Callie pulled a can of Behr Premium Plus Interior Eggshell Enamel from a shelf. The owner asked her if she was doing some painting. She confirmed. He asked where she was staying. She told him she was at that old apocalyptic ranch off of 99 and added it was her father's place. Callie grabbed two roller brushes. The owner was surprised the Dirt Farmer had a family. Callie started to understand everyone in Summerville called him the Dirt Farmer. Callie got a roller. The owner clarified he meant nothing by it. He explained Egon spent every week working a piece of land but never seeding, never watering, never growing anything. He rang up Callie's stuff. He found it curious behavior but reckoned Egon was a reat customer even thought what he bought was bizarre. Callie thought that sounded like him.

The "Cujo Attacks Car" scene played on the TV. Suddenly, there was an earthquake. The students looked around. Gary went to an instrument and watched it record data. Phoebe walked in and stared at his research on the wall. She asked what it was. Gary stood and tried to sway her to go back to watching "Cujo" in the other room. She asked about the seismic map. He asked her how she knew about that. She replied it was a map of seismic activity and realized he was a seismologist. He asked if that was so hard to believe. She figured him for a football coach. Gary was at a loss for words. She looked over his papers and noticed the earthquake was neither tectonic nor volcanic. Gary scoffed and went to the white board. He drew a volcanic and a tectonic earthquake and emphasized a little P-wave was followed by a large S wave. Phoebe knew that. He erased the waves and drew the pattern in Summerville. It was a large P-wave then a small S wave like an explosion. She asked where it was coming from. Gary had no idea. He admitted he even set up geophones, but was unable to triangulate the source. She asked him if he was using three. He confirmed he knew how many sides there were in a triangle. Phoebe joked she just thought he was being obtuse and winked. Gary paused then asked if that was a geometry joke. She confirmed it was and explained that was why she winked. Gary called it terrible but loved it. He directed her to the seismic map and explained to her that Summerville was not anywhere near a tectonic plate, had no underground volcanic activity, had no fault lines, no fracking was ever done, and there was no loud music even yet the town was shaking on a daily basis. Phoebe guessed it could be the apocalypse. He looked at her.

"Wait a Minute Girl" played at Spinners Roller Hop. Trevor was in the walk-in freezer counting patties and shivering and stuttering. He was at 25. Lucky referred to him as "no-skills" and asked how inventory was going. Trevor declared it was not good at all and asked if everyone did it. She assured him it was super important but noticed his lips were literally blue. He claimed he was fine. She offered her hoodie. He repeated he was fine. Lucky stated it was masculine and had a wolf on it. He conceded and stood up. She placed the hoodie on him. He was kind of surprised it fit him. She joked it was her boyfriend's. He switched to taking it off. The boys outside snickered. She ordered him to get back to inventory.

Podcast paused and readied his boom mike as he and Phoebe walked through town. He instructed her to just introduce herself and tell him what she ate for breakfast. She stated her first name and toast. Podcast asked for a little more and suggested a joke. She asked what you call a dead polar bear. Podcast had no idea. She replied anything you want since it can not hear you know. Podcast laughed and took his headphones off. He loved the joke and told her she was funny. She smiled and admitted it was a pretty hilarious joke. Podcast thought of a fun fact and revealed Summerville had more dead residents than living ones. She informed him that was how cemeteries work. He pointed out Wertheimer's Hardware and claimed it was run by the Illuminati and mentioned Lizard people. She keyed in on the latter. Podcast named Thomas Jefferson, Albert Einstein, and Beyoncé as examples of Lizard People. He asked rhetorically how she thought the pyramids came to be. She guessed slaves. Podcast told her the Napier Theatre was haunted. The signage advertised "Bingo" at 3 pm and "Cannibal Girls" at 7 pm. Phoebe revealed she did not believe in ghosts. Podcast stopped and turned around. He was shocked and pointed out all the evidence around. Phoebe believed humans were all just kind of meat puppets. Podcast got an idea. He stated there was something she needed to see and dashed off to grab his wheels. She followed after him.

They walked down the gravel road to the entrance to the Shandor Mining Company property. The broken fence was still not repaired from Egon ramming it. Phoebe asked if they were allowed to go inside. Podcast assured her it was totally okay. He informed her the mine was closed since the 1940s and the signs were put up because of hazardous chemical leaks and on account of dynamite. He demonstrated what he did and covered his nostril and mouth with his shirt. They walked towards a giant old cloth covering an entrance into the mine. Podcast told her the whole town was basically a mining operation and they bore out the mountain like a grapefruit and smelted everything into cold-riveted selenium girders. Phoebe wondered why they made a steel beam out of an electro conductor like selenium. Podcast agreed and found it weird. He continued and revealed they were forced to close down the operation. She asked why. He told her one by one, miners who had worked for years began leaping down the mine shaft to their death. They called it the Shandorian Curse. Podcast backed up behind the raggedy cloth and vanished. Phoebe peered in and followed. They look at carvings against a stone wall that matched those on New York City's Temple of Gozer. She asked who built it. Podcast replied it depended on who you believe. He claimed they just showed up one day without explanation. He remarked it was cool.

  • When Podcast and Phoebe walk to the Shandor Mining Company, the Dorothy Ferry Bridge was augmented with CGI to make the area look bigger.
  • Between trailers and the final version of the movie, the background behind Phoebe and Podcast as they walk to the bridge to the Shandor Mining Company was digitally modified.
  • It is revealed the Shandor Mining Company extracted selenium from the mines, a callback to the first movie, Chapter 20: Keymaster, when Ray Stantz noted 550 Central Park West was built with selenium girders.

  1. The Hollywood Reporter "Carrie Coon on ‘The Nest,’ Unanswered ‘The Leftovers’ Questions and Surreal ‘Ghostbusters’ Casting" 9/16/2020 Carrie Coon says: "The reason he's in Ghostbusters is because he happened to be in Canada with me and [our son] Haskell when they lost an actor due to a conflict, and so they just asked if he was around. So it worked out really well."
  2. CTV News Calgary "University of Calgary geoscience professor adds movie consultant to his title" 3/2/3022 David Eaton says: "I actually was just sketching on my whiteboard and some of the sketches that I made actually found their way into scenes in the movie.
