I have a LOT to add here, but no time. Gotta get to work, and today's a training day.
I'm convinced we're back to Mitchell and not Khan. Somehow, he didn't die this time. For most viewers, Kirk's history with him in 'Where No Man Has Gone Before' (recent Abramsverse comic adaptation) will be something that happened backstage, akin to the Countdown comics of the previous movie. See y'all soon.
