You can't fight them Doctor. There's no point. They're the future. A new life form. A better life form. It's very clear to me now, they made me understand. And we're to be their food.

Rassmussen

24 hours ago this station fell silent. No comm signal, nothing. Dead. We've come to find out why.

Nagata

The Doctor: But sleep is vital. Sleep is wonderful. Even I sleep.
Clara: When?
The Doctor: Well, when you're not looking.

What used to be sleep in your eye, has turned into a carnivorous life form.

The Doctor

Clara: What now? We can't stay in here, we're going to freeze to death. We can't go back out there because the sandmen will get us.
The Doctor: Sandmen?
Clara: Yeah it's a good name. Fits, like the song.
The Doctor: No no no no you don't get to name things. I'm the Doctor. I do the naming.

Clara: Ashildr?
Ashildr/Me: Ashildr?
The Doctor: That's your name. I keep telling you that.
Ashildr/Me: Do you? Infinite lifespan, finite memory. It makes for an awkward social life.

Rigsy: You're serious? You actually expect me to give you my death sentence?
Clara: I've always wanted a tattoo. You know, something small. Discreet.
Rigsy: Clara, cut it out.
Clara: Why aren't you listening? I'm under the Mayor's personal protection and it's absolute, apparently. Look she controls the raven, so I will never have to face it.

Ashildr/Me: I don't want your TARDIS. That's not what this is about. Rigsy come here, I'll remove your chronolock.
The Doctor: What is this Ashildr? You can't possibly think this is going to keep me here.
Ashildr/Me: It's not a restraint. It's a teleport bracelet.
Clara: What?
Ashildr/Me: I'll give you time to say goodbye, don't worry. No one will be hurt.

Clara: Okay, we split up. Cover more ground. I'm good cop, you're bad cop.
The Doctor: No no no we don't have... Can I not be the good cop?
Clara: Doctor we've discussed this; your face.
The Doctor: Oh yeah yeah.

Clara: That man's wife, she said something. Give it to me. Tell me I can have it. What did she mean?
Rump: Two ways to survive a quantum-shade. The shade's master removes the chronolock or you can give it to someone else.

You will not insult my memory, there will be no revenge. I will die, and no one else here or anywhere will suffer.

Clara

You’ll find that it’s a very small universe when I’m angry with you.

Doctor Who Quotes

There's a horror movie named Alien? That's really offensive. No wonder everybody keeps invading you.

The Doctor

The Doctor: It's a risk.
Graham: Oh, like none of our other trips have ever been risky.
The Doctor: I have apologized for the Death Eye Turtle Army! Profusely.
