Number Six: All of this has happened before. All of this will happen again.
Dr. Gaius Baltar: Everyone knows that verse. What are you getting at?
Number Six: Remember this one? Led by serpents numbering two and ten.
Dr. Gaius Baltar: The Vipers, they're the serpents?
Number Six: There's a later verse, Gaius. You should read it. Though the outcome favoured the few, it led to a confrontation at the home of the gods.
Commander William Adama: [Adama finds Lee sitting alone in the Viper hangar the night before a big mission. He sits next to him] Can't sleep? I couldn't either before a big op.
[Looks at Viper]
Commander William Adama: Mark II. Good ship. Got me out of a lot of tough scrapes. Got something for you. Belonged to your grandfather.
[Hands Lee a cigarette lighter]
Commander William Adama: My mom bought it for him when he was in law school. See the engraving on it?
Captain Lee 'Apollo' Adama: [the lighter reads 'Joseph Adama'] Yeah I can barely make it out but...
Commander William Adama: He was a better father than I was. Dad used to carry that into court cases. Claimed he never lost unless he left it behind.
Captain Lee 'Apollo' Adama: So you're worried too?
Commander William Adama: About what?
Captain Lee 'Apollo' Adama: You know sometimes it feels like the whole ship thinks uh, Starbuck would do better.
Commander William Adama: I don't.
Captain Lee 'Apollo' Adama: How can you be so sure?
Commander William Adama: Because you're my son.
[the two stare quietly at each other for a moment]
Commander William Adama: Get some rest. You're gonna need it.
[Gets up to walk away]
[Holds up lighter]
Captain Lee 'Apollo' Adama: I'll bring it back.
Commander William Adama: You better, or I'll kick your ass. That's a good lighter.
Elosha: Three thousand six hundred years ago, Pythia wrote about the exile and the rebirth of the human race. And the Lords anointed a leader to guide the caravan of the heavens to their new homeland. And unto the leader they gave a vision of serpents, numbering two and ten as a sign of things to come.
President Laura Roslin: Pythia wrote that?
Elosha: She also wrote that the new leader suffered a wasting disease and would not live to enter the new land. But you're not dying.
Elosha: Are you?
Commander William Adama: There are no reserve Vipers. Everything is on the board already. Now we play for all the marbles. Starbuck, it's your plan.
Lt. Kara 'Starbuck' Thrace: Mr. Gaeta will you please tell D to get on the scrambler and inform Apollo the back door is open?
Lt. Felix Gaeta: Aye, Lieutenant.
[on comm set to Dualla]
Lt. Felix Gaeta: D, please send a scrambler to Capt. Apollo. Message reads, The back door is open.
Officer Anastasia Dualla: Apollo, Galactica. Back door is open. Back door is open. Godspeed, Apollo.
