Spock is a character who lives in my mind to such a degree that I have headcanons I will fully forget if I've posted about before or are canon or widely accepted fanon or not because to me it's just a given. It is known. <- made it up
Anyway one ☝️ of which is that Spock's a little extra telepathic (melding with anything, melding through walls, mind controlling someone from across the room in that one episode everyone ignores because it was bad) Specifically because of his human ancestry making him lack some sort of inhibitor gene Vulcans usually have. Like ligers for psychics
I came to this conclusion like years ago because of the number of "what the fuck? Spock can do that?" Moments that happen in tos when the plot demands it & because it frequently goes against more established Rules for how Vulcans work it has to just be a Spock thing. From there the answer to "why is Spock built different" is kind of obvious. "Why does being half human make you more telepathic" is where the real specbio fun starts
Also! Implies the mechanism for Vulcan telepathy is different from Betazoid telepathy, as Deanna has weaker telepathy than average, also because of having a human parent. OR it depends on which parent is human. But I think the former makes more sense than having the genes divided up by chromosomes in the same way when they may or may not even Have the same chromosomes
That being said ☝️ if it's ligers for psychics (lion/tiger hybrids continually growing larger because they miss the Stop Growing gene) the Vulcan telepathy off switch would have to be carried on whatever Vulcan female typical chromosome Spock didn't receive from his mother. So. Keeping our terminology simplified so we're not here all day getting distracted by potential differences in sexual development, let alone Gender, this wouldn't happen with a Vulcan mother & human father. So even future mixed aliens may or may not be Like That, making it still Just Spock, depending
If a (m)vulcan/(f)human makes a Spock, a (f)vulcan/(m)human could be either telepathically normal or possibly stunted by Vulcan standards. And I just think that's neat
