I do have this question. In the prime universe, he was betrothed to T'Pring, which by Vulcan law made her his wife. Is that the situation in this new universe, and if so, does that make Spock an adulterer for having a relationship with Uhura?
Depends on a couple of things:
One, was Spock ever betrothed to T'Pring in the new timeline?
Two, was Spock an adulterer for having a relationship with Leila Kalomi from This Side of Paradise
Three, is T'Pring still alive. I'm just saying, with only 10'000 Vulcans left she very well maybe dead.
