I've never liked this episode. I dislike parallel Earth stories and the flag jumped the shark right off the Edge of the flat Earth. Good call about the Exeter orbit. Thrusters should be enough to adjust orbit for quite a while even without engine power. Very odd. I know people often claim that Janeway is madly contradictory but I guess Kirk assumes Tracey doesn't know he's a hypocrite. Whatever works on the mission at hand, that's our Kirk. Flirting with a minor, shagging an alien, calling Spock a half-breed and so on. It's interesting that the Yangs seem to have devolved so much. I wonder what kind of policies could have led to that outcome ;-p. There are some shades of Planet of the Apes in the overall dynamic.
