The second episode of the fourth season, "Six of One", set a couple of events in motion that will propel the saga forward in a big way as the season progresses.

For starters, we witnessed the resolution of Kara's assault on President Roslin, which ends, predictably, with Kara back in the brig. As expected, she elicits the maximum love/hate response from Adama, who nearly chokes her to death in her cell and then later... well, we'll get to that in a moment. One of the things you have to love about Adama is the depth of his feeling — he tends to be pretty hard on the people he loves the most, and in spite of the fact that he's disowned Kara before, the fact is that he does love her like a daughter and responds to this situation accordingly.

Kara's return from the "dead" — or wherever or whatever it is that she's returned from, if she is in fact the real Kara — has pretty much spun him out of control. He and Roslin argue about Kara's return and her insistence about having been to Earth. They take plenty of psychological swipes at each other along the way. While we know that Adama likes to kick back with a drink at the end of the day, in this scene he wavers uncharacteristically on the point of drunkenness. He's not only spinning out of control about Kara, he's also contemplating Roslin's impending death from her returned cancer, and Lee's departure from the military.

Speaking of Lee's departure from the military (he's been asked to take a seat on the Quorum and he's accepted), you'd think that, given the end-of-the-world-as-we-know-it thing, there'd be some kind of stop-loss policy in effect among the fleet. With a dwindling population and that whole "the Cylons are going to extinguish the human race" thing going on, you'd think that ace fighter pilots with command experience would be at a premium, but instead Lee gets to resign whenever the hell he feels like it. I don't find that scenario especially realistic, but I'm going to file it along with a lot of other things I like to wonder about (like why they were experiencing a food shortage but never seem to run out of stuff like booze or toothpaste).

Kara and Lee share a special farewell moment in the brig that feels like a real goodbye for them. I had the sense that they were simultaneously acknowledging their love for each other and recognizing that they had separate destinies to pursue at this point. The crew of Galactica turns out for a formal leave-taking ceremony as Lee (nattily attired in a god-awful pinstriped suit with a collarless shirt underneath — did I mention that the men on this show tend to look better in uniform?) departs the ship. He and Dualla have a scene here where they lay their dead marriage to rest in an amicable way, but that, too, feels as though it fell too neatly into place.
