You were stuck in a killing game. You're not sure if you should trust anyone yet so you decide to stay alone for now. It's pretty calm in the cafeteria right now so you go there. After a bit, Hibiki and Kanade walk in but they didn't notice you...

Kanade: You're so stupid!

Hibiki: flinches S-sorry...!

Normally Hibiki is pushing Kanade around...that's weird.
