On the way to school, Jon thought about how much different Sabrina and Tiffany could be now. Was Sabrina as fat as Gladys? Was she still a punk Goth? Was Tiffany still a slut? Did nerdy sluts exist?
When they finally got to the high school, Jon and Karyn decided to search for Tiffany. Assuming she'd be a nerd/geek in her new life, they decided to check the labs. Of course, she might not be there. But they had to start somewhere.
