“Dalek: I will talk to the Doctor.
The Doctor: Oh will you? That's nice. Hello!
Dalek: The Dalek strategem nears completion. The fleet is almost ready. You will not intervene.
The Doctor: Oh really? Why's that, then?
Dalek: We have your associate. You will obey or she will be exterminated.
The Doctor: No.
Dalek: Explain yourself.
The Doctor: I said, "No."
Dalek: What is the meaning of this negative?
The Doctor: It means, "No."
Dalek: But she will be destroyed!
The Doctor: No! 'Cause this is what I'm gonna do. I'm gonna rescue her. I'm gonna save Rose Tyler from the middle of the Dalek fleet, and then I'm gonna save the Earth. And then—just to finish off—I'm gonna wipe every last stinking Dalek out of the sky!
Dalek: But you have no weapons, no defenses, no plan.
The Doctor: Yeah! And doesn't that scare you to death? Rose?
Rose: Yes, Doctor?
The Doctor: I'm coming to get you.”

“When you run with the Doctor, it feels like it'll never end. But however hard you try you can't run forever. Everybody knows that everybody dies and nobody knows it like the Doctor. But I do think that all the skies of all the worlds might just turn dark if he ever for one moment, accepts it. Everybody knows that everybody dies. But not every day. Not today. Some days are special. Some days are so, so blessed. Some days, nobody dies at all. (In the library, the Doctor walks back to the TARDIS. He stops, looking at the doors. Then he raises his hand, and stands there poised like that for a long moment. Finally he snaps his fingers. The doors open. He smiles slowly and walks in, joining Donna. Then he snaps his fingers again, and the doors close. River's voice continues over this.) Now and then, every once in a very long while, every day in a million days, when the wind stands fair, and the Doctor comes to call... everybody lives.”

“This was like no library I had ever seen because, well, there were no books. Actually, I take that back. There was one book, but it was the lobby of the building, encased in a heavy glass box like a museum exhibit. I figured this was a book that was here to remind people of the past and the way things used to be. As I walked over to it, I wondered what would be one book chosen to take this place of honor. Was it a dictionary? A Bible? Maybe the complete works of Shakespeare or some famous poet.
"Green Eggs and Ham?" Gunny said with surprise. "What kind of doctor writes about green eggs and ham?"
"Dr. Seuss," I answered with a big smile on my face. "It's my favorite book of all time."
Patrick joined us and said, "We took a vote. It was pretty much everybody's favorite. Landslide victory. I'm partial to Horton Hears A Who, but this is okay too."
The people of Third Earth still had a sense of humor.”

“I travelled across the world. From the ruins of New York, to the fusion mills of China, right across the radiation pits of Europe. And everywhere I went I saw people just like you, living as slaves! But if Martha Jones became a legend then that's wrong, because my name isn't important. There's someone else. The man who sent me out there, the man who told me to walk the Earth. And his name is The Doctor. He has saved your lives so many times and you never even knew he was there. He never stops. He never stays. He never asks to be thanked. But I've seen him, I know him... I love him... And I know what he can do. - Martha Jones”
