Billy follows Teddy and stays in the doorway as he washes his hands, dimly aware that he's doing it because there's blood on them, and he can't forget the look in Tony's eyes as his face bled. He isn't even sure what that had been about, still doesn't understand, but he knows Teddy, and he knows he doesn't just up and punch people for no reason.

He likes to threaten them a lot, but that's usually when they're trying to hurt Billy.

"What happened?"
