[ The flush of warmth Castiel feels from Dean's sudden tight grip on his wrist isn't just due to the fever he can feel racing through Dean's skin. With the shiver passes, Castiel looks away, recognizing with guilt for the first time that he's put himself into a position, not only of authority, but as a caregiver, with Dean, and that it would be very easy to abuse that power. He gently pulls his hand out of Dean's grip, expression and voice going softer with a stiffness that might come across as forced, or poorly learned. What are people skills? Looking back, that joke was probably inappropriate, and Castiel's tone is as close to abashed as he can make it. ]

Dean... I wasn't actually going to get a saw, though I would like to get you antibiotics, along with some clean clothing, if that's okay.

[ After a moment, though, Castiel's forced embarrassment gives way to more natural concern again as he feels forced to ask, for clarity's sake. ]

You can feel your toes, right? I thought we were both joking, before.
