See how they play with her. See how they toy. They want her to run. They need her to run. Do you feel their need, Doctor? Their blood is screaming, "kill, kill, kill"! Hunter and prey, held in the ecstasy of crisis. Is this not life at its purest? [Clara runs]
Proposition. Davros is an insane, paranoid genius who has survived among several billion trigger-happy mini-tanks for centuries. Conclusion? I'm definitely having his chair.
Clara Oswald. I want Clara Oswald, safe, alive, and returned to me immediately! You bring her back -- you do that! You do that now! Unharmed, unhurt, alive.
There's no such thing as the Doctor. I’m just a bloke in a box telling stories. I didn’t come here because I'm ashamed. A bit of shame never hurt anyone. I came… because you're sick and you asked. And because sometimes, on a good day, if I try very hard… I’m not some old Time Lord who ran away. I'm the Doctor.
Or, even better, another relationship. Come on, you lot, you're bananas about relationships. You're always writing songs about them, or go to war, or gettin' tattooed.
I can't. Even the tiniest change, the ramifications could be catastrophic. It could spread carnage and chaos across the universe like ripples on a pond. Oh, well, I've had a good innings. This regeneration, it's a bit of a clerical error anyway. I've got to go sometime.
So break them. And anyway, you owe me. You've made yourself essential to me. You've given me something else to, to be. And you can't do that and then die. It's not fair. No, Doctor, I don't care about your rules or your bloody survivor's guilt. If you love me in any way ... you'll come back.
You will be a strong beacon. How many ghosts can I make of you?

You know, you've got a lot in common with the Tivolians. You'll both do anything to survive. They'll surrender to anyone. You will hijack other peoples' souls and turn them into electro-magnetic projections. That will to endure… that refusal to ever cease. It's extraordinary. And it makes a fella think! Because you know what? If all I have to do to survive is to tweak the future a bit, what's stopping me? Oh, yeah, yeah, yeah, yeah: the ripple effect. Maybe it will mean that the universe will be ruled by cats or something in the future. But the way I see it, even a ghastly future is better than no future at all! You robbed those people of their deaths; made them nothing more than a message in a bottle. You violated something more important than time: you bent the rules of life and death. So I am putting things straight! Here, now, this is where your story ends!
If the repair kit never stops working, then why did you give her two?
DThe Doctor
Immortality isn't living forever, that's not what it feels like. Immortality is everyone else dying. She might meet someone she can't bear to lose. That happens… I believe.
I saved your life. I didn't know that your heart would rust because I kept it beating. I didn't think your conscience would need renewing, that the well of human kindness would run dry. I just wanted to save a terrified young woman's life.
