Time Lords... cowardly, vain curators who suddenly remembered they had teeth and became the most warlike race in the galaxy. But you... You! You are curious. You've seen the words, too -- I can hear them tick inside you. But, you are still locked in your history. Still slavishly protecting time. Willing to die rather than change a word of the future.
Before the Flood
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!
The Girl Who Died
People talk about premonition as if it's something strange. It's not. It's just remembering in the wrong direction.
Winning is all about looking happier than the other guy.
[to Clara] I'm sick of losing people. Look at you, with your eyes, and your never giving up, and your anger, and your kindness. One day, the memory of that will hurt so much that I won't be able to breathe, and I'll do what I always do. I'll get in my box and I'll run and I'll run, in case all the pain ever catches up. And every place I go, it will be there.
I'm the Doctor, and I save people. And if anyone happens to be listening, and you've got any kind of a problem with that, to hell with you!
It won't stop, the repair kit I put inside Ashildr, not ever. It'll just keep fixing her.
Well, good.
I'm not sure, but it's entirely possible she has lost the ability to die.
The ability?
Oh, dying's an ability, believe me. Barring accidents, she may now be functionally immortal.
If the repair kit never stops working, then why did you give her two?
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.
The Woman Who Lived
Kill me.
Why?
If you intend any harm to this planet or its people, then killing me is by far your best move.
You invite your own death?
No. I just want you to attack first. Then my conscience is clear.
Of what?
You.
Why should I be responsible for you?
You made me immortal!
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.
You didn't save my life, Doctor. You trapped me inside it.
People like us, we go on too long. We forget what matters. The last thing we need is each other. We need the mayflies. You see, the mayflies, they know more than we do. They know how beautiful and precious life is because it's fleeting.
The Zygon Invasion
You left us with an impossible situation, Doctor.
Yeah, it's called peace.
I thought you didn't like being President of the World.
No, but I like poncing about in a big plane.
[points to the question marks on Osgood's lapel] Oh, I see you've accessorized it.
Yes.
The old question marks.
You used to wear question marks.
Oh, I know, yes, I did.
They were nice. Why don't you wear them anymore?
Oh, I do. I've got question mark underpants.
Makes one wonder what the question is.
Which one are you? Human or Zygon?
I don't answer that question.
Why not?
Because there is no question to answer. I don't accept it. My sister and I were the living embodiment of the peace we made. I will give all the lives that I have to protect it. You want to know who I am, Doctor? I am the peace. I am human and Zygon.
Like a hybrid.
A hybrid? If you like.
Well, I'm proud to know you, Osgood. And I promise that I won't tell anyone… that you're a human. Zygons need to keep the human original alive to refresh the body print. If you were a Zygon, you'd have changed back within days of your sister's death.
Those were the old rules. Before Zygons could pluck loved ones from your memory and wear their faces. Zygons only need to keep the original alive if they need more information from them. If the interrogation is over… then the original can die.
We want the truth of who we are to be acknowledged! We want to live as ourselves, at any cost. We want a home.
Well, you can't have the United Kingdom. There's already people living there. They'll think you're going to pinch their benefits.
