Tyrol: You know, they're talking about shutting down the marketplace. It's a security risk.
Tigh: We'll shift targets.
Tyrol: You were gonna hit the marketplace? The market? Full of civilians. This is crazy. You know, we need to figure out whose side we're on.
Tigh: Which side are we on? We're on the side of the demons, Chief. We are evil men in the gardens of paradise, sent by the forces of death to spread devastation and destruction wherever we go. I'm surprised you didn't know that.

Adama: Sharon can penetrate the Cylon defences.
Lee: It's not about her.
Adama: The Centurions can't distinguish her from the other humanoid models. Did you know that?
Lee: Admiral!
Adama: They were deliberately programmed that way. The Cylons didn't want them becoming self-aware and suddenly resisting orders. They didn't want their own robotic rebellion on their hands. You can appreciate the irony.

Roslin: I don't care that it's effective. I don't care that the Cylons can't stop it. It's wrong. No more suicide bombings, Colonel. You understand?
Tigh: What, are you working for the Cylons now?
(Roslin slaps him)

Tigh: I got one job here, lady, and one job only. To disrupt the Cylons, make them worry about the anthill they've stirred up down here so they're distracted and out of position when the Old Man shows up in orbit. The bombings, they got the Cylons' attention. They really got their attention. And I am not giving that up.
Roslin: We are talking about people blowing themselves up.
Tigh: You know, sometimes I think that you've got ice water in those veins. And other times, I think you're just a naive little school teacher. I've sent men on suicide missions in two wars now, and let me tell you something. It don't make a godsdamn bit of difference whether they're riding in a Viper or walking out onto a parade ground. In the end, they're just as dead. So take your piety, and your moralising, and your high-minded principles, and stick 'em some place safe until you're off this rock and you're sitting in your nice, cushy chair on Colonial One again. I've got a war to fight.

Boomer: Hi, Cally. It's me, Boomer.
Cally: I wish I had a gun.

Cally: Can you get me out of here?
Boomer: I don't know. I have nothing to do with internal security --
Cally: Then frak you, Sharon, you stupid frakked-up toaster! How many times do I have to shoot you, anyway? If you can't help me, then just go away, and leave us alone!

(a Five shoots Caprica-Six)
Baltar: Dear God.
Cavil: She'll be back.
Second Cavil: But if he pulls that trigger now, you won't.

Number Six: (to Baltar) Sometimes you have to do things you hate so you can survive to fight another day.

Sharon: Can I ask you a question? How do you know? I mean, how do you really know that you can trust me?
Adama: I don't. That's what trust is.

Cavil and Ellen's post-sex conversation about "the twist" and "the swirl" is a reference to the Seinfeld episode "The Fusilli Jerry". In said episode, the title character Jerry has a specially developed sex move, the details of which are never stated other than that it ends with the option of a pinch or a swirl in an unspecified way.
