Among some of the STB-based fic I'd love to see would be an exploration of Kirk not objecting once Spock explains "Lt. Uhura is in that facility, Jim." He's not just addressing his captain, he's addressing his friend who he KNOWS knows how much Uhura means to him. I love stories that show us S/U through another's eyes, and one that shows us why Jim so easily complied and why Spock knew he would could be amazing! With bonus Jim and Spock girl talk!!
I know, right?
I love that little bit because at first, he’s tries to rationalize it with faux logic like… Mister Chekov’s would be more useful on the ship I should go instead of him (can we just talk about the fact that he had probably tried his best to look like he was fine while they were making a plan to rescue the crew? and yet, when he walks around the table he has to place his hands on the back of Scotty’s chair for stability) but when Kirk, of course, outlogics him by mentioning his injury Spock gives up about even trying to hide the fact he wants to go just because SHE is there and.. fuck logic! It’s not logic but you gotta let me go there because you know I’m going anyway.
Bones also should be the first to stop him because, well, he’s a doctor, he knows what Spock is risking.. and yet, even Bones makes that face like.. of course he wants to go, we can’t stop him. Maybe the old romantic in him even wants him to go save his girl and it transcends his grumpy doctor self finding it stupid.
And Kirk’s ‘understood’ is simple like that, he doesn’t even try questioning him further, just the mere mention that lt Uhura is there is enough, Spock doesn’t need to explain it more.
Maybe other times he had argued with him, but he now knows it’s useless and he would go anyway. I think he saw stuff before, it’s years that they are in space and he works with them.. he knows, probably from previous experiences too, what happens when S/U are in danger. He knows what they mean to each other and respects that. Like
(comics above is from the after darkness ones, they had to leave a sick spock on new vulcan and kirk goes to uhura and is understanding it’s hard for her)
