I have this headcanon that when Jim gets older he starts feeling uncomfortable with people touching his hands and fingertips because although it means little in the human sense, he’d been using his hands to express his affection to Spock and Spock alone for so long that it kind of feels wrong when someone else tries to touch them.
Where freshly minted Captain Kirkreads up on stuff evenwhen he’s not on shift and nods off in random conference rooms on the Enterprise. Certain first officers who don’t require as much sleep take care of things.
Happy Valentine’s Day, I bear headcanons. Spock and Kirk, after retirement. They have an interview together because they’re famous starship captains, but Spock prefers to be known as the First Officer. They’re both past caring about decorum, so they show up dressed in civilian clothes. Kirk’s dug out his old green shirt and a jacket with a vintage NASA pin. Spock is bundled up. They’ve got a ton of in-jokes; the interviewer is bemused but entirely delighted over how affectionate they are. The vulcans are no longer scandalized—“It’s that science genius with his human again.”
