It's Saturday, for Stiles that means a lot. It means a lot more when he wakes up in Derek's bed and not his own to a very much probable empty house.

Stiles had just accidentally challenged an alpha. Not just any alpha, but the Hale alpha. Oh God, and Scott had just stood by and let him do it. He was the worst best friend ever. Stiles was going to kill him. Except, oh right, the alpha was going to kill him first. Like beyond dead, ripped into tiny little pieces dead. So far dead that his dad would not be able to identify him, dead.
