You wake up groggily, after a very long, but fun, night. There was a rave party in the common room, and all Slytherins were invited. You don't remember much, probably because you're stoned as hell.

You turn your head to the side and you see someone else next to you. You don't freak out, although you should, as neither of you seem to be wearing clothes. He's facing away from you, but you're almost certain you know who it is.
