Referring to twister's earlier comment, I happened to be thinking about that as I glanced at my Trek calendar. This month is Spock from Amok Time, and it gave me an idea. Maybe Spock is beating the crap out of Kirk in the trailer because he's pon farr-ing! He certainly had no trouble beating up Kirk in the series because of that. Granted, that would totally ruin continuity as well, but before I got pissed off because of it, I would certainly laugh heartily at the thought that Spock was choking Kirk on the bridge because Spock wasn't gettin' any!
