Clara: You. Now, you listen to me. You're going to be alone now, and you're very bad at that. You're going to be furious and you're going to be sad, but listen to me. Don't let this change you. No, listen. Whatever happens next... wherever she is sending you, I know what you're capable of. You don't be a warrior. Promise me. Be a Doctor.

The Doctor: What's the point of being a Doctor if I can't cure you?

Clara: Heal yourself. You have to. You can't let this turn you into a monster. So... I'm not asking you for a promise. I'm giving you an order. You will not insult my memory. There will be no revenge. I will die, and no-one else, here or anywhere, will suffer.

The Doctor: What about me?

Clara: If there was something I could do about that, I would. I guess we're both just going to have to be brave.
