The Doctor: Smile for me. Go on. Clara Oswald. One last time.
Clara: How could I smile?
The Doctor: It's okay. Don't worry. I'll remember it.

Me: You know why we run, doctor?
The Doctor: Become it's fun!
Me: Because we know summer can't last forever.

Clara: 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.

The Doctor: Don't run. Stay with me.
Clara: Nah. You stay here. In the end, everybody does this alone.
The Doctor: Clara...
Clara: This is as brave... as I know how to be. I know it's going to hurt you, but... please... Be a little proud of me. Goodbye doctor.

Pink: Do you know why people get together at Christmas? Because every time they do, it might be the last time. Every Christmas is last Christmas. And this is ours. This was a bonus. This is extra. But now it's time to wake up.

The Doctor: As you come into this world, something else is also born. You begin your life, and it begins a journey... towards you. It moves slowly, but it never stops. Wherever you go, whatever path you take, it will follow. Never faster, never slower, always coming. You will run. It will walk. You will rest. It will not. One day, you will linger in the same place too long. You will sit too still or sleep too deep... And when, too late, you rise to go... You will notice a second shadow next to yours. Your life will then be over.

The Doctor: If you think because she is dead, I am weak, then you understand very little. If you were any part of killing her, and you're not afraid, then you understand nothing at all. So, for your own sake, understand this. I AM THE DOCTOR. I'm coming to find you, and I will never, ever stop.

The Doctor: Never trust a hug. It's just a way to hide your face.

River: If this is the last night, I expect you to find a way round it.
The Doctor: Not everything can be avoided. Not forever.
River: But you're you. There's always s loophole, you wait until the last minute and then you spring it on me.
The Doctor: Every night is the last night for something, every Christmas is the last Christmas...
River: But you will. You'll wait until I've given up hope, all will be lost, then you'll do that smug little smile and then you'll save the day- you always do.
The Doctor: No, I don't, not always. Time's end, River, because they have to. Because there's no such thing as happy ever after. It's just a lie we tell ourselves because the truth is so hard.

The Doctor: Once, long ago, a fisherman caught a magic haddock. The haddock offered the fisherman three wishes in return for its life. The fisherman said, "I'd like my son to come home from the war and 100pieces of gold." The problem is, magic haddock, like robots, dont think like people. The fisherman's son came home from the war in a coffin and the King sent 100 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 your city proves anything, it is that granting all your wishes is not a good idea. In fact, the fisherman wished, that he hadn't made the frist two wishes.The Doctor: Once, long ago, a fisherman caught a magic haddock.

The Doctor: The nice thing about life is however bad it gets, there's always one last option available -- Dying well.

The Doctor: I don't believe much. I'm not sure I believe anything. But right now... Belief is all I am. Virtue is only virtue... in extremis.

The Doctor: The end of your life has already begun. There is a last place you will ever go, a last door you will ever walk through, a last sight you will ever see, and every step you ever take is moving you closer. The end of the world... is a billion, billion tiny moments. And somewhere, unnoticed... In silence or in darkness... It has already begun.

The Doctor: Winning? Is that what you think it's about? I'm not trying to win. I'm not doing this because I want to beat someone, or because I hate someone, or because I want to blame someone. It's not because it's fun. God knows it's not because it's easy. It's not even because it work, because it hardly ever does. I do what I do, because it's right. Because it's decent. And above all, it's kind. It's just that. Just kind. If I run away today, good people will die. If I stand and fight, some of them might live. Maybe not many, and maybe not for long. Hey, you know, maybe there's no point in any other of this at all. But it's the best I can do, so I'm going to do it. And I'll stand here doing it till it kills me. You're going to die too. Some day. How will that be? Have you thought about it? What would you die for? Who I am is where I stand. And where I stand... is where I fall.
