"Well," the angel began with a slight tilt of his head, inspecting the man in the bed, "Physically you look like you've been through a meat grinder." Ah yes, there it was. But it was rare Castiel worried much about physical things.
A hand lifted some, the seraph taking on a more serious look-- as if Cas could get much more serious. "I could heal you." An offer between the two of them. It would get Sam up and moving around again, it would put a halt to all that pain. Of course, it would cause some questions with the doctors and other patients.. it wasn't like this was some random town that they could pass through and just be some strange story the locals tell.
But neither Dean nor Castiel wanted to see Sam in such pain, so the offer was there. It was always there.
Cas had promised to take care of the youngest Winchester. And he would.
