Yeah, it seems like the well-intentioned-yet-completely-idiotic kind of thing Sam would do. I sure as hell hope he doesn't. I saw someone, somewhere, suggest that Sam is kind of all jacked up from the demon blood still and maybe he is going to stay away from Dean because he is afraid of himself. That made sense to me. But man, if he is back and Dean thinks he is in Hell and then Dean finds out otherwise - oh boys, seriously.

I would "yes, sir" Bobby anyday.

Castiel getting emotions, like understanding them, but still all awkward, it's the best.
