- Ruby Sunday: Is that a monster?
- The Doctor: No. No, don't be silly. Ruby there's no such thing as monsters - there's just... Just creatures you haven't met yet.
- Ruby Sunday: How do you keep going?
- The Doctor: For days like this, Ruby Sunday. I don't have a people, I don't have a home... But I don't have a job, either. I don't have a boss, or taxes, or rent, or bills to pay. I don't have a purpose, or a cause, or a mission, but I have... freedom. That's why I keep moving on, to see the next thing, and the next, and the next. And sometimes... It looks even better through your eyes.

- Ruby Sunday: Hey, but you said the TARDIS was like a chameleon - but it still looks like a police box.
- The Doctor: Oh, it's, uh, it's broken. Most of the universe is knackered, babes.
