Bill: What is that?
The Doctor: *That* is my theme tune, otherwise known as a distress call!
Bill: You *like* distress calls?
The Doctor: You only really see the true face of the universe when it’s asking for your help.

Space, the final frontier. ‘Final,’ because it wants to kill us.

The Doctor

You don’t have to go to outer space to find monsters. There’s plenty of things that wanna kill you right here on Earth!

Nardole

All right, you lot. Back to the estate agents. Better luck next time!

The Doctor

What’s the point of surviving if you never see anyone, if you hide yourself away from the world?! When did you last open the shutters?

The Doctor

Hope is its own form of cruelty.

The Caretaker

Harry: I’m scared.
The Doctor: Don’t be.
Harry: Why?
The Doctor: It doesn’t help.

Honestly, Doctor, there’s nothing going on! Nothing weird, nothing alien! Just an old house and a dodgy landlord, which is pretty standard for students.

Bill

The Doctor: Did you hear the tree squeaking when you arrived outside?
Bill: Yeah. It was the wind!
The Doctor: There wasn’t any wind...

The Doctor: I told you, you don’t steer the TARDIS, you reason with it.
Bill: How?
The Doctor: Unsuccessfully, most of the time.

Bill: Doesn’t anybody ever notice the TARDIS?
The Doctor: Your species hardly notices anything.

Bill: How is *that* a screwdriver?
The Doctor: In a very broad sense!
Bill: Oh, and how’s it sonic?
The Doctor: It makes a noise!

Doctor Who Quotes

Only in darkness are we revealed. [...] Goodness is not goodness that seeks advantage. Good is good in the final hour, in the deepest pit, without hope, without witness, without reward. Virtue is only virtue in extremis. This is what *he* believes, and this is the reason above all I love him, my husband. My madman in a box. My Doctor.

Nardole [quoting River Song]

Once, long ago, a fisherman caught a magic haddock. The haddock offered him three wishes in return for its life. The fisherman said, “I’d like for my son to come home from the war. And a hundred pieces of gold.” The problem is, the magic haddock, like robots, don’t think like people. The fisherman’s son came home from the war, in a coffin. And the king sent a hundred gold pieces in recognition of his heroic death. The fisherman had one wish left. What do you think he wished for? Some people say he should have wished for an infinite series of wishes, but if your city proves anything, it is that granting all your wishes is not a good idea. [...] In fact, the fisherman wished he hadn’t wished the first two wishes.
