[ Sam's in the kitchen, pacing as he waits for some kind of response on the screen, and while he's not really used to angels suddenly dropping in on him, as much as that's been happening lately, he's too distracted to do much except to stop short before he walks right into Castiel. His clothes are bloody in several spots, some of it his own, and his jeans are torn, but that's also pretty low on his list of priorities right now. If he was in pain before, he's not feeling it now.

On the other hand, he's between Cas and the front room where Jack is and there's a flicker of hesitation. He doesn't know the angel as well as Jack does, as well as his older self apparently does, but the fact that Jack has gotten as close to him as he has to him and Dean counts for something. He just hopes he won't regret this later. ]

Can you help him? I think... I think he'll bounce back, but I'm worried he's not strong enough to hold out that long.

[ That's the impression he's gotten from talking to Jack, anyway. ]
