But here s something a bit different—tucked into a second response addressing George Takei s disappointment, co-writer Simon Pegg has shared his explanation for this change, given that the movie timeline only diverged from the original Trek universe upon Nero s arrival in the 2009 movie.
Seeing as Nero went back in time and created the Kelvin timeline in 2233, it s hard to see how his arrival would have changed the sexual preference of young Hikaru Sulu, born on Earth in 2230.
The implication is that since Sulu hadn t been shown as gay in the original Star Trek TV series and movies, this felt like saying he had been closeted, which is where Takei s major problem lay.
Pegg has a different thought, one rooted in the alternate universe theory paragraph breaks added for clarity :
With the Kelvin timeline, we are not entirely beholden to existing canon, this is an alternate reality and, as such is full of new and alternate possibilities.
Well, the explanation comes down to something very Star Treky; theoretical, quantum physics and the less than simple fact that time is not linear.
