So if JJ's take on Trek ends with a third film, I have an idea for the ending. Spock Prime ends up finding a way to get back to his own timeline. He goes back to Vulcan...yay, it's there. Then, he goes to earth, knocks on a door. A lady answers, we don't see her face. Spock hands her a rose. She says, "I always knew you'd come back to me." Then it's revealed to be Uhura (Nichelle Nichols). They kiss. Oh snap! So it happened in the prime timeline too! Non-S/U-shippers everywhere are eternally pissed! Fade to black.
