or is he?
I don't read much of the surrounding non-screen materials of the Abramsverse, so I don't know what's supposed to have happened with nuSarek between Star Trek XI and STID. It seems like every other character who had a decent-sized role in the previous movie and didn't die came back in STID except Sarek.
So Spock Prime is off on the New Vulcan colony. Is Sarek there? And if not, why not? Spock Prime and Sarek Prime had a troubled relationship, but that seems to not be as much the case in the Abramsverse. Wouldn't Spock Prime appreciate the opportunity to get more time with Sarek? To look on it as a second chance at a better relationship?
