I have a recollection of somebody posting what they said was QT's story here somewhere. It didn't go down well. I think everybody thought it was a joke, or some fan fiction riffing off Pulp Fiction out of sequence storytelling. Which of course, it in all probability it was.
It seemed to mix Star Trek Generations nexus and Kirk's fate. The opening scene begins with presumably gangsters who are holding Kirk, Spock and McCoy prisoner. Somehow they are able to show each a glimpse of their own futures. My memory is a bit sketchy after that, but Kirk's is obviously some restaging of his death on Veridian III, and the way they wanted Shatner involved. It seems plausible looking back now, as QT readily admitted he really didn't get that whole Kelvin universe set-up and how Shatner-Kirk's ultimate fate isn't necessarily Pine-Kirk's.
