Spock gets his Katra back, but he and McCoy end up with like, residual personality traits from each other. And they’re both Pissed Off about it.
Bones? is *marginally* quicker at Maths, which hey, not bad.He can also tell you a pretty accurate history of Vulcan if pressed. H o v e v e r; he uses the word “fascinating” in everyday conversation, and looks Pained every time . Alcohol never quite tastes the same which is an utter Devastation bc booze makes up a good third of his personality at this point. Like what, he’s supposed to deal with James T Kirk sober?? rip to this man.
and Spock? everyone on the bridge just about shits themselves when they realise who’s been humming ‘sweet caroline’ for the past 5 minutes. Including Spock. He’s no physician, but he can now tell you which alien species known to the federation have appendixes. What he meant to say to that poor cadet was “I fail to see the logic in your actions”; what came out was “what the Fuck was that?”
(Scotty’s never quite recovered from the time he brought up an embarrassing story from the 5 year mission, and was simultaneously flipped off by both the chief medical officer and the first officer. Legend says Jim is still crying with laughter to this day.)
