This is it. The darkest day. The blackest hour. Chin up, shoulders back. Let's see what we're made of, you and I.

The Doctor

Do you know the key strategic weakness of the human race? The dead outnumber the living.

Missy

The Doctor: That's a matrix data slice, the Gallifrey hard drive. Time Lord technology.
Missy: Imagine you could upload dying minds to that, edit them, rearrange them, get rid of all those boring emotions ready to be redownloaded. Meanwhile you upgrade the bodies. Download the mind, upgrade the body. Cybermen from cyber space. Now why has no one ever thought of that before?

Dr. Chang: There is one horrible possibility that has never occurred to anyone throughout human history.
Clara: Don't say it.
Dr. Chang: The dead remain conscious. The dead are fully aware of everything that is happening to them.

This isn't really an afterlife, it's just more life than you were expecting.

Seb

Danny: Wi-fi. You have iPads in the afterlife.
Seb: iPads. WE have Steve Jobs.

Missy: My heart is maintained by The Doctor.
The Doctor: Doctor who?
Missy: Doctor Chang!!!

The Doctor: Clara? You asked me what we're going to do, I told ya. We're going to go to hell, or wherever it is people go when they die, if there is anywhere. Whatever it is we're gonna go there and we're gonna find Danny. And if it is in any way possible, we're going to bring him home. Every culture has a concept of an afterlife. I always meant to have a look around, see if I could find one.
Clara: You're going to help me?
The Doctor: Well, why wouldn't I help you?
Clara: Because of what I just did, I just...
The Doctor: You betrayed me. You betrayed our trust, you betrayed our friendship, you betrayed everything that I've ever stood for. You let me down!
Clara: Then why are you helping me?
The Doctor: Why? Do you think that I care for you so little that betraying me would make a difference?

The Doctor: If I change the events that brought you here, you will never come her and ask me to change those events! Paradox loop. The timeline disintegrates, your timeline, and yes!
Clara: Yes?
The Doctor: I did just say no. Throw away the key.

You told me once what it would take to destroy a TARDIS key. That's what's so good about lava. All seven from all of your hiding places.

Clara

Danny I will never say those words again, not to anybody else. Ever. Those words from me are yours now.
