"Just things that need to get done." Honestly, Doc doesn't mind the alone time at all, but he doesn't necessarily duck out for those long hours just because he wants to be left alone. He's had quite enough of alone to last a few lifetimes.

"If anyone can glare that fog into submission I suppose it'd be you." They haven't had to fend off another bout of vicious fog. Strangely enough, the days where they were only worried about the fog seemed like a blissful window of their time in Mathias. Things had seemed so much less complicated than they are today. Or at least, they (naively, perhaps) only had fewer things to worry about back then.

That Doc is worried about Raylan having gone overboard already is left unsaid. Doc worries about a lot of things, even though he might brush them off or play them down. It's evident enough to see in his eyes and in his posture. They don't need to comment about it unless Raylan is feeling particularly defensive. Nobody would blame anyone for going overboard by now. Least of all John Henry. They shoulder more than anyone humanly should.

"I wouldn't mind the other distractions you come with. Small talk or... whatever else catches your fancy." They can save small talk for the porch, although one might argue that porch talks are far more important than just idle banter. Or pillow talk, if cowboys do anything other than sleep and snore on them. Empty another bottle of 'shine and Doc might start mentioning something downright scandalous.

"I'm not drinking you dry, am I?" He can always go fetch another crate bottle, but then he'd have to get up and leave the house.
