Nowhere Man
Commodore
what i mean is, we could see Spock overseeing his younger self and a young Kirk in the movie, sort of protecting them from the shaddows like Obi-Wan did in Episode 4 Star Wars. al the while trying to Stop Nero. I think then at some point he will introduce himself to his self, formaly or informaly. Then towards the end he will be doing all the technicall work, like Obi-wan did in " A New Hope" , and much like Spock would anyway. Then finally sacrificing himself once agian , so the others can live, but this time he dies for real real and not for play play
