(stopped it there because it gets a bit too much for my taste)
seriously, you can’t convince me that Spock didn’t start to truly beat the shit out of Khan WHEN Uhura got there and Khan was advancing to her. He wanted to kill him already before, that was his mission (and pretty much what she meant too with her ‘go get him’) but he was loosing the fight and he didn’t even seem to have much of a chance to win against the dude (and really, the biggest thing he did was attempting to nerve pinch him) but after she gets there Spock starts to break things and bones.
Just the moment when he realizes Uhura is there and his eyes widen like that? In a fraction of seconds he goes from amazement, because she saved him, to panic when he looks around for something to use to stop Khan who is advancing to her and she won’t distract him for long (she like had zero chances against him, which further makes me love her. She went there with a phaser set to stun only against a superhuman who could kill her with a blink of his eyes, she risked her life to save both Spock AND Kirk and she doesn’t get enough credit for that.)
Spock is like a living definition of what happened when that fucking last straw broke the camel’s back.
