It felt... wrong, in a way, seeing Charlie like this. The fact he's all but ass-naked doesn't necessarily bother him, but for the fact it's seeing Charlie vulnerable, seeing all his scars and vulnerable splayed against John's chest.

But still, the shivering going down is promising, and he breathes a sigh of relief when he puts a hand on Charlie's chest, feeling his pulse fluttering less weakly beneath his fingers.

"Better," he says, with no small relief. "Good job, John." He brushes the folds of his cloak aside to expose Charlie to the fire more. "Try and catch some of the warmth in here, i-it'll help. When he stops shivering we'll start adding blankets again."
