"You want to break the cycle?" Gaius literally says, with Saul and Ellen staring down at them. "Break the cycle of birth, death, rebirth; destruction, escape, death? Well, that's in our hands, and our hands only. Requires a leap of faith. Requires that we live in hope, not fear." He actually says that, like the first college freshman to ever drop acid he says it.
"If I leave you this girl, that means the destruction of my people. How does our extinction fit into this picture that you want us to believe in?" Seeing Cavil's point, and how it is actually relevant in a way Gaius's awkward bullshit isn't, Saul blurts, "We'll give you resurrection!" Ellen and Caprica are appalled. "You give us Hera and we will give you resurrection. But the war ends here. You leave humanity in peace and give up the pursuit, now and for all time." And Cavil agrees, because for once that is exactly the point. Whatever happens now, the 145s can't reproduce, and frankly if pulling it out of Hera's brain is the only answer, they're screwed anyway. Let them retrograde, and the rest of us will actually progress.
Bill's like, "On the other hand, you're a snake, so how do we know?" Cavil squints at him and says, completely out of character except for the nastiness and irony he brings to it, "You don't. You have to make a leap of faith." Saul says it's Bill's call, but he'll back the play, and Bill's like, "You are killing my doodz." Cavil asks for the phone and I guess Sam links him right up, because suddenly he's telling the whole Colony force to stand down, and they do. The dogfight ends, and Hotdog reports it; Bill orders everybody in CIC to chill out, and Hera runs into Caprica's arms. "I'm as good as my word," Cavil says, and Bill stares him down.
The Vipers return home; the Raiders go home too. Doral looks down at his dead brother, shoots a bitchy look at the Final Five, and then hovers near Cavil accusingly. Simon stands way close to Lee as he and Kara get the reports from the fighter wings: Four Vipers down, and seven Raptors. This is the least effective battle of all time. Nobody died in the melee except some extra Dorals and Simons, not a single one of our guys, and four Vipers? The Colony unleashed hell and they got four whole Vipers total? Maybe that's God too, since he's in charge of everything and nothing now. Athena holds her daughter tightly; Caprica strokes her arm and smiles with Laura, as if to say, "That was awesome how I walked down the hall, no? Glad everything turned out okay. And stupid."
