DOCTOR: Come on, please. Give us this. It's all right, it's me! Stabilise. Come to Daddy. I mean Mummy.

DOCTOR: Want to borrow my shades?

GRAHAM: Oh, ta.

DOCTOR: Like an old pair of mine. I say mine. Can't remember who I borrowed them off now. It was either Audrey Hepburn or Pythagoras.

GRAHAM: Eh? Pythagoras never wore shades.

DOCTOR: You obviously never saw him with a hangover.

DOCTOR: Do you two know what that is?

EPZO: It's a tent.

EPZO: Listen to me. Nobody is jettisoning anything. This is the Cerebos, all right? She's the envy of millions.

DOCTOR: Really?

EPZO: Yes, people have written songs about her.

DOCTOR: They'll be writing operas about our pointless deaths if we don't take drastic action right now.

EPZO: Whatever happened here is in the past. What does it matter to you?

DOCTOR: This was a living, breathing planet once. With an ecosystem, organic life, and a population. There was a catastrophic event here. And as hard as it is for you to understand, you are not the only lifeform in this universe. Some of us feel a duty to others who might be in trouble. So fix your wound, take one of your heroic naps, and we'll wake you when we leave – if you're lucky.

DOCTOR: (looking down a hatch leading underground) I want answers about this planet and I think they're down there.

GRAHAM: You sure about that?

DOCTOR: Nope! Come on.

ANGSTROM: How did you even do that?

DOCTOR: Did I not mention? I am really smart.

DOCTOR: Venusian aikido. I'm a Grandmaster Pacifist.
