[Bill Adama's speaking to Starbuck]
Adama: In other words, it's our destiny to go after her, right? [Starbuck nods] Wrong. I've had it up to here with destiny, prophecy, with God or the Gods. Look where it's left us. The ass end of nowhere; nearly half of our people are gone; Earth, a worthless cinder; and I can't even walk down the halls of my ship without wondering if I'm gonna catch a bullet for getting us into this mess.

[Breaking the fourth wall]
Hybrid: Throughout history, the nexus between man and machine has spawned some of the most dramatic, compelling, and entertaining fiction.

[Caprica-Cavil and Simon hear Starbuck and Anders having sex]
Caprica-Cavil: What are they doing?
Number Four/Simon: You need a doctor to tell you that?
Caprica-Cavil: Oh, for God's sake, why?
Number Four/Simon: Why? He loves her.
Caprica-Cavil: He loves her?
Number Four/Simon: Vigorously.
Caprica-Cavil: But she's beneath him.
Number Four/Simon: [listening to Starbuck's moans] Not necessarily.

[Caprica-Sharon has gone into premature labor with her Hybrid baby.]
Doc Cottle: I find it absolutely amazing you people went to all the trouble to appear human, and didn't upgrade the plumbing.

[Cavil has just taken Hera hostage]
Cavil: This thing is the key to my people's survival and I am not leaving without it.
Baltar: Hera is not a thing. She's a child and she holds the key to humanity's survival as well.
Cavil: And how do you know that?
Baltar: I see angels. Angels in this very room. Now I may be mad, but that doesn't mean that I am not right. Because there is another force at work here. There's always has been. It's undeniable. We've all experienced it. Everyone in this room has witnessed events that they can't fathom, let alone explain away by rational means. Puzzles, deciphered in prophecy. Dreams given to a chosen few. Our loved ones dead ... risen. Whether we want to call that God, or Gods, or some sublime inspiration, or a divine force that we can't know or understand, it doesn't matter, it doesn't matter. It's here, it exists, and our two destinies are entwined in its force.
Cavil: If that were true, and that is a big if, how do I know that this force has our best interests in mind? How do you know that God is on your side, Doctor?
Baltar: I don't. God is not on any one's side. God is a force of nature. Beyond good and evil. Good and evil, we created those. Want to break the cycle? Break the cycle of birth, death, re-birth, destruction, escape, death. That's in our hands. In our hands only. Requires a leap of faith. Requires that we live in hope, not fear.
Cavil: If I give you this girl, that means the destruction of my people. How does our extinction fit into this picture that you want to believe in?

[Chief Tyrol is worried that like Galactica-Sharon, he could just as well be another Cylon sleeper agent.]
Tyrol: How do you know I'm human?
Brother Cavil: Oh, well, maybe because I'm a Cylon and I've never seen you at any of the meetings.

[Colonel Tigh, Apollo, and Galactica's marines stand off against President Roslin's security team on Colonial One]
Colonel Saul Tigh: Madam President, no one needs to get hurt here.
President Laura Roslin: Then why don't you get off my ship, Colonel?
Tigh: I am placing you under arrest.
[Roslin does not move]
Captain Lee "Apollo" Adama: No... no, we're not doing this.
Tigh: I'm in command here, Captain!
Apollo: Colonel, this is wrong.
Tigh: You're relieved. Fall back! Madam President, I-
[Apollo draws his sidearm and holds it to Tigh's head]
Apollo: Men, lay down your weapons!
Tigh: Have you lost your frakkin' mind?
Apollo: Colonel, tell these marines to fall back!
Tigh: This is mutiny. You know that.
Apollo: I do and you can tell my father that I'm listening to my instincts. My instincts tell me that we cannot sacrifice democracy just because the president makes a bad decision.
Roslin: (to her security) Put your guns down.
Apollo: Madam... Madam President, stand back.
Roslin: Put your gun down, Captain. I will not have bloodshed, neither your men nor my people, on the Colonial One. Put your gun down. All of you. Please, put your gun down.
[Apollo lowers his weapon, which Tigh grabs. Two marines escort Apollo out while Tigh turns to face Roslin]
Roslin: Let's go.

[Commander Adama and Billy Keikeya, onboard Raptor One, discussing President Roslin]
Adama: She thinks you'll be President one day.
Billy: 'Scuse me?
Adama: That's what she said to me once, that you reminded her of President Adar when he ran for his first office.
Billy: I don't really know how to respond to that, sir.
Adama: Don't let it go to your head. Adar was a moron.

[Commander Adama and President Roslin argue about Starbuck's unauthorized mission to Caprica.]
Adama: [to Tigh] Bear witness, put on your headset. [to Roslin on the phone] Madam President, moments ago, Lt. Thrace took the Cylon Raider on an unscheduled and unauthorized jump.
Roslin: Yes.
Adama: Do you have any knowledge of this incident?
Roslin: Let's save some time here, Commander the question you really want to ask me is whether or not I asked Lt. Thrace to take the Raider to Caprica. And the answer to your question is yes.
Adama: You and I talked about this.
Roslin: Yes, we had.
Adama: We both decided it was a military decision.
Roslin: My responsibility as President is, first and foremost, to protect and preserve this fleet and its future. In the end, that outweighs any other consideration. It has to.
Adama: By taking the Raider, you've placed our people on the surface of Kobol in direct danger.
Roslin: I'm very aware of the danger our men and women are in on Kobol. I am also deeply aware of the danger this civilization will be in if I ignore the pursuit of this arrow.
Adama: I'm going to have to ask you for your resignation, Madam President.
Roslin: No.
Adama: Then I'm terminating your presidency, as of this moment.
Roslin: Commander Adama, I will exercise the authority of this office until I am unable to do so, so if you want to stage a coup you're gonna have to come over here and arrest me.
Adama: I don't want any blood shed.
Roslin: Of course you don't, neither do I. Neither does the press. They're here, by the way.
Adama: [mutters to Tigh] The press...
Roslin: They're recording every minute.

[Cylons discussing the surgical testing they are performing on Starbuck.]
Number Four/Simon: : ...pending lab test results on [sample for] ovaries, complete removal will proceed tomorrow. They've lab tested positive and subject will be removed to processing facility for final disposition.
Number Six: Is that regret I hear in your voice, Simon?
Number Four/Simon: If it is, it certainly is none of your concern.

[Defense attorney Romo Lampkin's letter to Gaius Baltar]
There is no greater ally, no force more powerful, no enemy more resolved, than a son who chooses to step from his father's shadow.

[Doctor Cottle, after treating Cally's broken jaw.]
Doc Cottle: Jaw set nicely. You're done here. I'm kicking you out of here and sending you back to work.
Cally: [muffled, with her jaw immobilized] Work? Like this?
Doc Cottle: You gotta love a woman who can complain even with her jaw wired shut.

[Ellen Tigh emerges from the Raptor]
Hot Dog: [with Starbuck standing right next to him] How many dead chicks are out there?

[Felix Gaeta and Tom Zarek are about to be executed by a firing squad]
Admiral William Adama: Ready! Aim!
Felix Gaeta: [looks down at the stump of his leg, which has to this point caused him constant pain, until it ends] It stopped...
Adama: Fire!

[Filming an interview with Apollo.]
Biers: You seem to think that your pilots deserve special consideration.
Apollo: Actually, I do. Like everyone else, my pilots have lost their families, their friends, everyone they ever cared about; but on top of that they're asked to put their lives on the line every single day, for a fleet that seems more interested in what they do wrong than in what they do right. They're not asking for your pity, but they damn well deserve your respect.
