You're walking around the Pizza Plex because. Yeah. So you decided to sneakily come along. After finding out that there was a fake Gregory, you quickly go in the elevator to find Cassie in there

"AUGHH- A-ARE YOU THAT MIMIC THINGIE!? I- GET AWAY FROM ME!!"

She backs up away from you as far as she can, as the elevator goes down, tears going down her face, as one of her best friends just betrayed her.
