"I think I have hypothermia," he pointed out, when it occurred to him that Adam's breath was staining the air, but his wasn't. That and, of course, the fact that he suddenly couldn't stop shivering, despite how heavy his limbs felt. "It's--I'm healing, but not fast enough."

Probably because of all the trauma from killing himself again and again and again. Or, maybe, as Adam had pointed out, because he was still wearing his coat, wet and cold and not helping.

He made a face, reaching up to peel it off sluggishly, only to drop it on a long abandoned chair a moment later. His clothing was still wet, but no where near as saturated as the coat had been, and even if that was making things worse? It wasn't as though he could simply strip--then the cold would bite at him, just as surely as the wet had been, a moment before.
