Doc is more prone to despair and melodrama when he's steeped in fear and uncertainty. He has outbursts, yes, but even then there is some amount of control leading up to them, and some amount of pushing is required to get him to snap. Maybe it is the century-long isolation or maybe it is how he has always coped when he was too sick to snap, but his preferred method of coping right now is to withdraw.

There is clearly no getting a word in sideways with Raylan unless Doc wanted to start a fight - he didn't; not with the guy with the knife and not when he knows they would both end up saying something they would regret - and there is not really a means to stopping him, either. In the end they split up, Doc staying behind as White Hat rolls on relentlessly ahead.

He hangs around beneath their house, pacing a bit before lighting up a cigarette in the dark. That little '1306' scratched into the stone is the only comfort they have down here. Not even Hurricane Raylan ripping on ahead and the receding echo of his determined footsteps could make Doc want to go closer to the sound of the water.
