Spock should have figured out he was a queer waaaaay sooner. Look at the women he's drawn to (not romantically) and with whom he has good relationship with.
Una (Broadway musical nerd with fantasies of being a star on stage to full houses every night). Pelia (should be self explanatory just by everything about her.)
As an autistic queer, Spock... Spock, baby, sweet summer idiot... im NOT gunna hold your hands when I tell you this... but you're a big ol' flaming Queen...
But we all gotta figure that out on our own. Luckily for Spock, he has now mind melded with Jim. So. He's basically 'doomed' at this point. XD the bond that formed was 100% an accident, and they won't, but I would LOVE for Spock to be freaked out about it. Even if just secretly in private to himself. Literally has no other plot relevance. Jsut occasionally him going into a corner and having a spazz before composing himself.
And then one day Jim surprises him by just... answering a question Spock didn't verbalize because Jim isnt psychic but the link is there, and the question sense likely filtered through (Jim 100% is clueless and thinks he's just observant af and noticed Spock's quizzical vulcan expression) and Spock has to either play it cool, or talk to Jim.
