Lol. This is one issue I'm of two minds on. On the one hand, yes, Kirk could've used his position and pulled rank and say "Hey, you two, if you don't knock it off, I'm gonna turn the ship around!" But, OTOH, Kirk and Uhura basically came up through their classes together as classmates (if not, at first, as friends)...so their relationship, rank notwithstanding, is fairly informal. This is another thing I like about the Abrams Treks in that, even though I'm inclined to believe that Starfleet IS a military organization, the JJ films often avoid the military trappings on the Enterprise, especially since some of Kirk's crew are former fellow classmates and peers. Kirk and Uhura, in their more private moments, can speak more as friends, rather than CO and subordinate. (a dynamic that exists often in the real-world military). (witness the turbolift scene where Uhura let's Kirk know "it's not you." for an example.). Later, in the K'normian transport, when they are about to enter Ketha Province on Q'onoS, the "friends" relationship is a bit more prevalent rather than the Captain and crew dynamic. I thought it rather charming. I also liked the brief dynamic between Kirk and Mr. Hendorf (aka Cupcake). You can see the sort of Captain/subordinate dynamic between them (even though they both are/were also classmates), but it is not a grudging distinction from Hendorf...rather it comes across as a matter of heartfelt respect. Kirk got them through the Nero/Narada incident, and Kirk has a solid grip on the situation to try and avoid war with the Klingons, from Hendorf's POV. Something tells me that Hendorf would ferociously defend the life of his Captain not just as a matter of duty, but a matter of friendship. Personal opinions only.
