Captain Reynolds: You will explain your presence, and the nakedness of this girl.
Doctor: Are we in Scotland?
Captain Reynolds: How can you be ignorant of that?
Doctor: I'm dazed and confused. I've been chasing this wee naked child over hill and over dale. Isn't that right, you timorous beastie?
Rose Tyler: Och, aye. I've been "oot" and "aboot."
Doctor: No, don't do that.
Rose Tyler: Hoots, mon?
Doctor: No, really don't. Really.
Face of Boe: I had grown tired with the universe, Doctor, but you have taught me to look at it anew.
Doctor: There are legends, you know, saying that you're millions of years old.
Face of Boe: That would be impossible.
Doctor: Wouldn't it just. I got the impression there was something you wanted to tell me.
Face of Boe: The great secret.
Doctor: So the legend says.
Face of Boe: It can wait.
Doctor: Oh, does it have to?
Face of Boe: We shall meet again, Doctor. For the third time, for the last time. And the truth shall be told. Until that day... (disappears)
Doctor: That is enigmatic. That... That is textbook enigmatic.
Doctor: What have you done to Rose? And I'm being very, very calm... you want to beware of that... very, very calm. And the only reason I'm being so very, very calm is that the brain is a delicate thing. Whatever you've done to Rose's head, I want it reversed.
Lady Cassandra (possessing Rose): I'm perfectly fine.
Doctor: These people are dying. And Rose would care.
Novice Hame: Legend says that the Face of Boe has watched the universe grow old. There's all sorts of superstitions around him. One story says that just before his death, the Face of Boe will impart his great secret, that he will speak those words only to one like himself.
Doctor: What does that mean?
Novice Hame: It's just a story.
Doctor: Tell me the rest.
Novice Hame: It's said he'll talk to a wanderer, to the man without a home, the lonely god.
Doctor: Planet gone, all rocks and dust, but the human race lives on, spread out across the stars. As soon as the Earth burns up, oh, they get all nostalgic, big revival movement. They find this place, same size as the Earth, same air, same orbit, lovely. The call goes out, the humans move in.
Rose Tyler: What's the city called?
Doctor: New New York.
Rose Tyler: Oh, come on.
Doctor: It is! The City of New New York. Strictly speaking, it's the 15th New York since the original, so that makes it New New New New New New New New New New New New New New York. What?
Rose Tyler: You're so different.
Doctor: New new Doctor.
Jackie Tyler: I reckon you're mad. The pair of you. It's like you go looking for trouble.
Doctor: Trouble's just the bits in-between. It's all waiting out there, Jackie. And it's brand-new to me. All those planets, creatures and horizons, haven't seen them yet. Not with these eyes. And it is gonna be... fantastic.
Doctor: I should have stopped you.
Harriet Jones: What does that make you, Doctor? Another alien threat?
Doctor: Don't challenge me, Harriet Jones, 'cause I'm a completely new man. I could bring down your government with a single word.
Harriet Jones: You're the most remarkable man I've ever met, but I don't think you're quite capable of that.
Doctor: No. You're right. Not a single word. Just six.
Harriet Jones: I don't think so.
Doctor: Six words.
Harriet Jones: Stop it.
Doctor: Six. (to Alex): Don't you think she looks tired?
(Harriet Jones orders an attack at the Sycorax's ship, making the ship explode over the Earth...)
Doctor: That was murder.
Harriet Jones: That was defense. It's adapted from alien technology. A ship that fell to Earth ten years ago.
Doctor: But they were leaving.
Harriet Jones: You said yourself, Doctor, they'd go back to the stars and tell others about the Earth. I'm sorry, Doctor, but you're not here all the time. You come and go. It happened today. Mr. Llewellyn and the Major. They were murdered. They died right in front of me while you were sleeping. In which case, we have to defend ourselves.
Doctor: Britain's golden age.
Harriet Jones: It comes with a price.
Doctor: I gave them the wrong warning. I should have told them to run as fast as they can. Run and hide because the monsters are coming. The human race.
Harriet Jones: Are there many more out there?
Doctor: Ooh, not just Sycorax. Hundreds of species. Thousands of them. And the human race is drawing attention to itself. Every day you're sending out probes, messages and signals. This planet's so noisy. You're getting noticed, more and more. You better get used to it.
(The defeated Sycorax runs after Doctor to attack him from behind, Doctor throws satsuma at a button, making the Sycorax fall from the ship...)
Doctor: No second chances. I'm that sort of a man. (to the Sycorax gathering): By the ancient rites of combat, I forbid you to scavenge here for the rest of time. And when you go back to the stars and tell others of this planet, when you tell them of its riches, its people, its potential, when you talk of the Earth, then make sure that you tell them this: It is defended.
