T'Pring is not going to want his half breed DNA. They don't need their breeding program diluted with humans. She didn't want him in Amok Time when this wasn't even an issue on a global scale as it is now. I'd be surprised if the Vulcan Powers That Be would even allow this to proceed.
This is a new time-line--we don't know what this T'Pring will want.
The Vulcan planet has been obilterated...billions of vulcans gone....New Vulcan has a small colony...she as well as the elders may be more open to inter-mixing (word?
) as they are a very logical bunch. Spock wouldn't be ideal if she had an entire planet to choose from but in this new situation ....he's not a bad choice by a very long mile
She didn't want him in Amok Time...but this is not TOS ....so who knows except the next writer
<<<Upon re-reading this sounds a bit snarky---but it's not meant to be. I don't want to change it though because hopefully my meaning is plain and direct and I prefer that>>>
