He glowers angrily. He's wrong. Wrong, wrong, wrong. This guy knows Bobby, knows he gave him the necklace, but — but that's not right at all. He takes a step forward, face a little flushed. "This is mine. Bobby gave it to me — I'd never give it to John. And don't you fucking talk about my mom!!"

He grabs a book and throws it hard, the fear replaced with blind rage. He's not allowed to hit Dean, certainly not allowed to hit John, but this isn't either of them — can't be, just can't be. He grabs anything he can get his hands on and flings it at his head, and then he makes a mad dash for the door. If he can get out, get away, he can run.

(And find John and Dean

No, he should run away, he could do it if he wanted to

But they're all that stops him from being evil

He hates them so much he could die.)
