Rebecca Gorin met Erin Gilbert and Abby Yates, after the team moved into the Firehouse, while she examined the Containment Unit. Erin tried to get her attention. Holtzmann kicked herself for not introducing Gorin to everyone then proceeded to. Holtzmann noted that Gorin is her mentor. Gorin assessed the Containment Unit's current state as "reckless" and informed Holtzmann that all someone had to do was sneeze too hard and everyone in the Firehouse would disintegrate. Holtzmann admitted it was completely unstable and laughed as she patted Gorin's right shoulder with her green rubber gloves. Gorin asked if they needed a certain safety light. Holtzmann quipped safety lights were for dudes. Gorin was amused. Holtzmann chuckled and high fived Gorin. Gorin shook her head and stated she hated doing that.
During the dimensional bleed incident, Gorin observed the whole city turned into what amounted to a living representation of Escher's Relativity. Two weeks after the two dimensions were separated and returned to normal, Peter Venkman and Ray Stantz paid their world a visit to rebuild their Containment Unit. Peter started to warm up the idea of giving Interspatial Teleportation Units to other Ghostbusters. He reckoned they could have a decent bowling league if they could avoid blowing up the universe. Gorin believed that would be extremely unlikely. Peter immediately noticed she was that dimension's version of Dana Barrett. Holtzmann introduced her. Peter asked her if she was ever turned into a dog. Gorin replied she never experimented with those sorts of pharmaceuticals. Peter and Gorin joked about the 'other kinds.'
Gorin seems to share some of the same mannerisms as Holtzmann but is not animated like her.

- Cineblog "Ghostbusters, Paul Feig in Rome: a report from the press" (retrieved through Google Translate) 6/27/16 Line reads: "Weaver was immediately enthusiastic, from day one. We had thought about a different role for her, but we realized that it was too little of substance, so we changed it. He loved the idea of doing the mentor of one of the four protagonists, because excited by the idea to fake a German accent."
- Yahoo! Movies "Screenwriter Katie Dippold on How 'Ghostbusters' Changed and Why 'The Heat 2' Isn't Happening" 7/20/16 Katie Dippold says: "Sigourney was probably the one that was most written for someone. And that one was the hardest one to figure out… God, I pitched on so many different versions of that cameo. One I wanted to do, but it was real hit or miss, when no one was believing them, as they're driving in the city, and then this woman walks up, Sigourney Weaver, and she's just like, "Hey, you know what? I don't care what anyone says, I think what you guys are doing is great, and I absolutely believe everything you're saying." And then they're like, "Oh my God, thank you so much." And there there's a couple options. One is she just walks away and then just lays down on the ground like a crazy person. Another one was she says that same thing to someone else on the street. Because she's just a crazy person who just says this to everyone."
