Here's something: What during TOS or TAS leads Spock to decide to pursue Kholinar and the purging of all emotion? I've always accepted it as given, but it's never been something I've ever been able to crack.
I'm sure it's probably explained in the Lost Years novels from the '90s, but I haven't read them.
