[Roslin changes Baltar's bandage]
Laura. There's been something I've been meaning to say to you. I wanted to thank you.
Essentially, for not murdering me. That can't have been an easy decision to make. But I love living. I love living, and I wanted to thank you for saving my life.
I wouldn't be so grateful if I were you. You should know that I told the Admiral that if D'Anna doesn't back down, he should blow the ship to pieces.
[Tigh comes to Adama's quarters just before the extremely risky attempt to rescue the Baseship hostages begins]
Bill, you gotta scrub this mission.
What the hell are you doing here? You're supposed to be in the CIC.
The Cylons will kill every godsdamn hostage before we put one pair of boots aboard their ship. Laura Roslin will be the next to die, Bill.
I'm looking for options. You got one?
Yeah. I should've told you when I first found out, but I didn't have the guts.
What's wrong with you, Saul?
You remember back at the nebula when I told you about that frakking music? I thought it was in the ship. I was wrong. It was a signal. Some kind of crazy, frakked-up Cylon signal switched me on. I can't turn it off.
[not wanting to understand] Switched you on.
Like Boomer. I'm one of the Five.
One of the Cylons D'Anna's after.
[rising from his desk] Quit frakking with me. Colonel, I've known you for 30 years. When I met you, you had hair. I've never heard of a Cylon aging.
Doesn't mean they don't. Before the attack on the Colonies, we didn't know the skinjobs existed. Turns out there's another kind of Cylon we didn't know about, and I'm one of them.
[desperate] On New Caprica, you were in captivity. They did something to you, they... An implant, a post-hypnotic suggestion that makes you feel this way. Let's go talk to Doc Cottle...
[grabs Adama by the shoulders] Listen to me! It is not a delusion. It is not a chip in my head. I am a Cylon. I've fooled you for months now. I didn't want to, but I did.
Get your hands off of me.
[releasing him] If I'd had the guts to airlock myself when I first found out, we wouldn't be in this mess. But that's the way out. Not this suicidal attack. I am one of the Final Five. D'Anna will back down if you threaten to flush me out an airlock.
[After learning that the truth about Tigh being a Cylon, Adama is reduced to a sobbing wreck in his son's arms]
Okay. Dad, Dad, Dad, listen. No one suspected. No one. Not with his record, what he did on New Caprica. His eye, what happened to his wife... [tries to haul his father back to his feet] Come on, let's get up.
What have I done? All the people I've sent to die, for what? For what?
AAdama
There is no Earth. It's a frakking joke. There is no Earth.
Okay, Dad, listen to me. Listen to me! Pull it together.
AAdama
I can't... I can't kill him. I can't kill the bastard. I can't. I can't.
Okay, Dad. It's gonna be okay. It's gonna be okay. I'll take care of it.
