There's a bright flash of light and several unconcious people appear in a room, "Here we go again." Someone says sighing although they're also smirking.

Being knocked unconcious was not in Kate's day plan, then again she didn't plan on meeting her dead bestfriend either. Her plan was to spend some quality time with her girlfriend while the latter rambled about climatology, so Kate Did not expect to see Chess, Farrah, Clark and Riley getting up off the ground looking just as confused and dazed as she felt. "Riley fucking Williams. Nice to see you again." She spat at the redhead once the two made eye contact.
"Kate." The former cheer captain spat back with equal hostility. 
"So.. how the hell did you escape from prison?!"
"I didn't, I was randomly telaported here." Kate was about to make a come back but then thought better of it since she was also randomly telaported into this theatre room so she just glared at her. "Kat...?" Another voice says, Kate reconizes it immediately, she turns around to face the direction that the voice came from. "Chess!?" Without thinking, Kate runs and tackle hugs her bestfriend who somehow wasn't dead anymore. "How!?" That was said by Cairo. 
"I don't know." Chess says honestly. She then turns to face Kate. "Listen, I'm so sorry, I betrayed your trust and-"
"Shut up, I shouldn't have said that to you, I should've stayed and helped you get better."
"Kate-" Chess is cut off by someone exclaiming;
"J.D!?" The rest of the Tigers plus Clark (since all of them were awake by now.) turned towards the direction of the voice.

Veronica's day had just gone from normal to exremely weird in seconds. First, she was telaported into a theatre room with her friends (Heather Mcnamara and Martha) and Heather Duke. Then she was face to face with the one and only Heather Chandler along with Kurt, Ram and of course, Jason Dean. "J.D!?" She exclaimed, staring in shock at her no longer dead ex-boyfriend. "Veronica..."
"How are you.. alive?"
"No clue." Veronica tried to resist the urge to hug him.
"Veronica, haven't seen you since you PUT DRAIN CLEANER IN MY HANGOVER CURE." Chandler says, raising her voice at the end of the sentence. "I didn't mean it-" Veronica starts saying and then launches into an explanation of what happened. Chandler looks slightly less mad but she still glares at Veronica. 

This had to be some sort of joke.
Janis was at Damian's house, watching a movie with him and Cady when all of a sudden, she was telaported to a theatre room. She looked around, there were a bunch of other teens there as well as the former plastics, Aaron, Cady and Damian. "Do any of you know what's going on?" Asks Cady. "Absolutely not." Damian says. 

All of a sudden, the sound of a bell is heard and everyone turns towards it.
