"Sorry," Doc grumbles quietly, flexing his hand. "I've been-- a little. Unnerved." Loathe as he is to admit even that much. "Since the fire." He's still not overly keen on touching Raylan, or being touched, but he does slowly extend his hand, turning it over slowly. At least this time Doc is prepared for it, and while he still won't like it, he can probably try to behave, without flinching.

"What happened? You look like you've seen a ghost." A ghost that must have done something to his hand, if Raylan is taking such a keen interest in it. The Marshal isn't usually this interested to look at his hand, even when they're alone and getting, well, handsy.
