Good line, rhetorically speaking, but useless in this context, because that's not what this fight is about, not even for Lee. It's not even true: the reason they have to depend on the 268s now is because human beings fucked up the Scrolls of Pythia, and Kara led everybody, Cylon and human alike, down an oracular cul de sac. Earth would be a frakload whether or not the Cylons did anything at all. This is meant purely to hurt Tigh's feelings, and it does, and that's the entire function of it: Tigh is beyond sad about it, even though it's not really his problem or his responsibility, and way to go Captain Apollo. You got self-righteous and hurt somebody that has nothing to do with what's going on. How Cally of you. No wonder Zarek loves you so much. Kara comes back and urges them forward to the next safe point.
Chief waits, nervous, with the prophets. Gaius stands in a corner, thinking nervously, and then suddenly pulls it together and picks up a phone. (Is that trackable? Should he just be blithely dialing CIC from their secret location?) Gage answers and looks at Felix, willing him not to get gay about this, and Gaeta makes a sour face even as his hand is heading for the phone of its own accord. "What do you want, Gaius?"
"What do I want? I want this to stop. Now. Right now. This is madness." Check out how he pulls out all the stops: "This doesn't become you, you know. Treason, or whatever they're gonna call it when this thing is through. I know you, Felix. I know you're a good man. You're an honorable man. You want to do the right thing." We love you, we love you, we love you. That is exactly how he gets to sleep with anybody he wants: because he is a player. However, that's only half the story with Gaius: "Even your failings have been understandable." Ouch. The tide turns, and this will not end well. Felix is like, "Oh, like serving in your corrupt administration?" Um, no. The thing I am always talking about in these conversations: Sweet Eight and the seduction of hope. "Our little secret? Sealed with a very special pen?" Felix loses the entire plot again, and waits for Gaius to hang up. Gaius doesn't even know how bad he fucked this up. "But I forgive you for that, Felix. I'm telling you... if you are hungry for redemption, this is not the way..." Gaeta hangs up on him and he talks to the air ("Felix, please...") before giving up. And the saddest thing about that is that he's all alone when he makes that call, and the only way he'd ever tell anybody he was willing to play the slightly queer Gaius/Gaeta card is if it worked out. So it's one more good thing Gaius tried to do, that nobody will ever know about. That's becoming quite a list.
