Especially as two things become clear: number one, he has lost not only the thread but interest in the thread, and number two, as usual, he's going to seriously fuck everything up without even slightly trying. Maybe this time worse than the first time, if you think about it. Yes, every scene is about fathers, disappointment in fathers, and yes, you can bring that to Adama's door and I'm sure everybody's about to, but only Gaius Baltar could give an disinterested extemporaneous sermon about his personal religious disaffection that results not only in a riot but also in accidentally aims the Fleet's murderously profound religious and cultural disappointment squarely at Bill's head. He's like the anti-Zarek. One more reason to love him.
"What manner of forgiveness are you seeking? Is it that of disobedient children? Are you... Are you children? -- Well, obviously you're a child, we have some children here, but -- To the rest of you, in your mind's eye, are you all just children who've transgressed against your father's divine will? Are you being punished for your multitude of sins? Are you? Is this really our lot? To have been led by a father to the Promised Land?"
I think it's Lilly who says no, they shouldn't have to suffer. He leans over, way over, losing the plot as he's sitting there, drunk and stuck in his own pain, unredeemed for the sixty-sixth episode in a row... (Holy shit, do you realize we're exactly as far from breaking ground on New Caprica as we were then from the Miniseries? That's brilliant. How do we measure badass? 33 minutes, around and around, and start the clock again: 33 episodes from the Holocaust to New Caprica and the Second Exodus, 33 episodes thence to Earth and the Third Exodus. That is AWESOME. This show is so fucking good.) Anyway, he sort of fades, and the hot one with extra Jesus in her boobs is like, "Just keep talking." It doesn't really matter what he says. All they want to do is connect. That's all he's ever wanted, too. As far back as Cuffle's Breath Wash, as far forward as wanting to be Cylon.
"...To Paradise... Only to have Paradise cruelly smashed to bits before our very eyes? Are these the actions of a father towards his children? No! It's not right!"
Galen stands at the back of the ground, like he often does, and reconsiders his stance on the Nicky thing. First, he will find the dad and beat the shit out of him for cutting this last tie to his humanity. Even after the memories came back on Earth, he still had Nicky; when Nicky got sick he wept. Then, he will get very drunk. Then, he will do the thing that Galen does best, which is fix things. Naked and broken, he can still do that. He can keep going.
