Follow up to the post by @crystal-mouse, a friend found this on Ebay a while back. It's a 1960s Ken Doll but could also pass as a Soong prototype pre Data and Lore (maybe they needed a modesty subroutine too? lmfao)
Babe Spock is so autistic coded in this episode it hurts. And I LOVE that they show him both sure of himself, but also on the edge, unsure, he doesn't understand why it's not working, he's frustrated.
I think this episode shows well the complexity of Vulcan's relationship with feelings. Because so many emotions in this man! Oh boï.
