Okay, so part two is confusing me. What's the deal with elderly Spock? Given the lack of goatee, references to the Federation, Starfleet, Kirk being a good man, and that the Terran Empire is something from an alternate reality he once encountered, he's obviously not from the MU from the other Trek episodes. However, he can't possibly be Spock Prime either, can he? After all, if he were, than how the hell could Nero be in this MU's Rura Penthe and killed by Kirk last month? My guess is this Spock is supposed to be from another universe similar to the Prime Universe.
Anyone else have thoughts/explanations?
