I can't remember is I've asked this before but here goes.
If the Abramsverse is only supposed to be like an alternate timeline from the point that Nero arrives, why does Khan look different than the Khan of the Prime Universe?
Ok, chime in and please try to avoid "because it's J J Abrams" or similar. I would like a good reason as to why this would be the case or even an official one, if such exists.
Apparently a comic series they're coming out with actually is supposed to explain this discrepancy. It'll still be completely stupid, but there's something to be said for actually recognizing it.
(Of all my issues with Into Darkness though actually having a guy who looked like Khan was admittedly low on the list.)
