[ Castiel can tell at once that his savior is not Dean or Sam. They'd take up most of the doorway, and this lithe figure does not. Fortunately, he doesn't have to wonder as to their identity for long.

Ruby, of course. Because between three different kinds of abduction, his luck couldn't possibly be about to change. He strains against the chains instinctively, but there's only enough give in them for him to flex muscles, for the wings on his back to stretch and quiver, and fall still again. Fighting is a waste of his energy; he'd established as much days ago. And he can tell that when it comes to Ruby, his energy is far better conserved. She has no reason to torture him for information, he supposes, but he had stood in her way, stood between her and Sam on more than one occasion. He wonders if she holds that against him. Probably. Demons are, if anything, less predictable than humans, and Castiel has had enough difficulty with them.

If his expression had been tired before, it takes on a new effort of resistance, gathers his strength to look defiant for a moment or two. His head still aches, but if he can squint through the sparking lights behind his eyes, he can defy her, no matter what her reasons are. Perhaps she will kill him, he wonders. He doubts she'll set him free, considering what he might have to tell Sam and Dean. He could stop them, prevent this. Perhaps she doesn't know, in which case he's not in a hurry to tell her. There might be a fight here after all.

[ But perhaps he shouldn't have implied that there was anything to tell. ]

Have you come to cut me down?
