I for one don't understand how Kirk and crew could be encounter these same situations in 2258, when these things happened before in 2266/2267. Why is the plague that Enterprise responded to in Galileo 7 happening almost a decade earlier? Why is Deneva under attack from the mysterious parasites 10 years earlier? It doesn't make logical sense to me, and the writers don't offer any logical explanation in the comics, as far as I see... it really draws me out of the story, because it doesn't make sense. Also, why would Mitchell have been friends with Kirk back in the Academy... his history wouldn't have been changed by the Nero incident in 2233, so wouldn't he have already graduated the academy by the time nuKirk entered, in 2255?
