. The fates of the Number Ones, Fours, and Fives are uncertain, .
It's also revealed that
, the score can be heard playing the theme from the original series.
In addition to the Raiders seen in "Islanded in a Stream of Stars", the colony also has Centurions left over from the first Cylon War. Their absence until this point is most likely due to being an obsolete model and would have been inadequate in combat.
In a sort of fitting bookend, the museum that had been set up in Galactica is seen for the first (and last) time since the miniseries. However, the Centurion in the display case has been retconned to fit in line with the design of the original Centurions as seen in "Razor".
However, director Michael Rymer thought the line was milking it too much and eventually dropped it.
It was Edward James Olmos's idea to have
Roslin: Thank you, Doctor.
Cottle: I'm just doing my job.
Roslin: No. You've done much more than that. You've taken, uh, a patient that should have died years ago, and you've given her a chance, despite cancer and the Cylons and her own obstinate nature. And you've... you've given me the little time I have left, and for that, you... you have my... my heartfelt... gratitude and my thanks.
Cottle: Well, I - I - I don't know what to say.
Roslin: No, no, don't, don't. Don't spoil your image. Just light a cigarette and go and grumble.
Adama: We'll be in too close for nukes. Same thing goes for missiles. No, this is going to be strictly a gun battle. Like two old ships on the line, slugging it out at point-blank range. I want the gun captains to do their job and start firing immediately and to continue to fire until they run out of ammo. Then, I want them to start throwing rocks.
Adama: Just so there'll be no misunderstandings later, Galactica's seen a lot of history, gone through a lot of battles, this will be her last. She will not fail us if we do not fail her. If we succeed in our mission, Galactica will bring us home. If we don't, it doesn't matter anyway.
Number One: This thing is the key to my people's survival, and I'm not leaving without it.
Baltar: Hera's not a thing. She is a child, and she holds the key to humanity's survival, as well.
Number One: And how do you know that?
Baltar: I see angel, angels in this very room. Now, I may be mad, but that doesn't mean that I'm not right. Because there's another force at work here. There 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 prophesy. 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 destines are entwined in its force.
Number One: If that were true - and that's a big "if" - how do I know this force has our best interests in mind? How do you know that God is on your side, Doctor?
Baltar: I don't. God's not on any one side. God's a force of nature, beyond good and evil. Good and evil, we created those. You wanna break the cycle? Break the cycle of birth? Death? Rebirth? Destruction? Escape? Death? Well, that's in our hands, in our hands only. It requires a leap of faith. It requires that we live in hope, not fear.
Number One: If I leave you this little girl, that means the destruction of my people. How does our extinction fit into this picture that you want us to believe in?
Tigh: We'll give you resurrection.
Tigh: 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.
Number One: Agreed.
Adama: How do we know we can take your word for it?
Number One: You don't. You have to make a leap of faith.
Cottle: Their DNA is compatible with ours.
Baltar: Meaning we can breed with them.
Adama: You got a one-track mind, Doc.
Baltar: What? Listen, I'm talking about the survival of the human race, actually, not some get-together with the natives.
Adama: You also have no sense of humour.
Roslin: It's a very beautiful world. Does it have a name?
Roslin: It's not Earth.
Adama: Earth is a dream, one we've been chasing for a long time. We've earned it. This is Earth.
Lee: You know, my very earliest memory of my father was him flying away on a big plane and wondering when he was coming back. He's not coming back this time.
Kara: No, he's not. Neither am I.
Lee: Where are you going?
Kara: I don't know. I just know that I am done here. I've completed my journey and it feels good.
Kara: So what about you? What are you gonna do? Today is the first day of the rest of your life, Lee.
Lee: Well, I always thought when this was all done I would, uh, kick back, relax, spend the rest of my days doing the absolute minimum humanly possible.
Kara: And now that you're here?
Lee: I want to explore! I wanna climb the mountains. I wanna cross the oceans. I wanna... Gods, I can't believe I'm saying this. It sounds so exhausting. I must be crazy.
(Lee turns around to see that Kara has completely vanished)
Lee: Goodbye, Kara. You won't be forgotten.
Roslin: (last words) So much... life.
Number Six: Commercialism, decadence, technology run amok. Remind you of anything?
Gaius Baltar: Take your pick. Kobol, Earth - the real Earth before this one - Caprica before the fall.
Number Six: All of this has happened before --
Gaius Baltar: But the question remains, does all of this have to happen again?
Number Six: This time, I bet no.
Gaius Baltar: You know, I've never known you to play the optimist. Why the change of heart?
Number Six: Mathematics. Law of averages. Let a complex system repeat itself long enough, eventually something surprising might occur. That, too, is in God's plan.
Gaius Baltar: You know it doesn't like that name. (pause) Silly me. Silly, silly me.
