Darryl can't have gone sleepwalking according to his card. Unless we have some sleep fairy casting spells on another user, I am inclined to believe that sleepwalking claims are mafia making excuses for visiting folks with the intent to kill. Of course, I admit I'm assuming that "intent" part, given the lack of evidence.
I claim to have sleepwalked; does that make me scum? Obviously I was targeted by someone which made me sleepwalk, and either Darry was too, or he knew about it because it was one of his teammates who's making people sleepwalk.
I'm more inclined to think it was the first at this point. It'd be hard to think that scum can "move" people around yet can't manage to kill a single townie.
