There are some really good character moments here, too. I love watching how each member of the crew comes to the realization that Kirk isn’t Kirk. With Spock, he’s completely skeptical right up until he reads “Lester’s” mind and realizes that, yeah, that’s the captain, and from that point on, he’s completely on Team Jim. McCoy is actually the first to notice that something’s wrong, but he also is insistent that there be evidence (so is Spock, but he can get his by touching his fingers to someone’s nose and cheekbones), and he hasn’t gotten any yet. Scotty doesn’t come around until he sees Lester being all binky bonkers, and he eventually manages to convince McCoy. Chekov doesn’t come around until Lester calls for the death penalty. And most interestingly, Sulu doesn’t seem to give a damn one way or the other because the only thing that matters to him is that three people have been ordered to their deaths, and there is no way he’ll let that stand, no matter who’s giving the order. And good for him.
