The Doctor: Come on then, you lot. Places to go!
Yaz: When you say 'Places to go!' where you thinking? Where to next?
The Doctor: I was thinking... EVERYWHERE!

The Doctor: It's shutting down the wi-fi, the phone signals... Woah, that Dalek just shut down the whole of Britain's Internet.
Graham: What, on New Year's Day? When everything's shut and everyone's hung over?
Ryan: What a monster.

Oh, you're good, Ryan's Dad. You're almost making up for your parenting deficit.

The Doctor

The Doctor: How are you feeling, Lin?
Lin: Shaky
The Doctor: I'm not surprised. You will for a while. But you kept fighting it, thank you. Take these. Three a minute for four minutes. Don't take with alcohol, you'll grow an extra head. That was an embarrassing party.

Yaz: How'd it go? What happened?
Ryan: Did you get rid of it?
The Doctor: Not quite.
Yaz: How much 'not quite'?
The Doctor: Not at all. Slightly riled it and let it get away. And now it's in a tank, trying to summon the fleet.

Dalek: Humanity will surrender!
The Doctor: They really won't, trust me. I've seen them in action. They've fought off so many things, including the worst of their own people. They're really stubborn. Have you not worked that out yet?

The Doctor: So that's what you've been doing. Reconstructing yourself from memory and remnants... and spare parts?
Dalek: I am rebuilt!
The Doctor: What do you call this look? Junkyard chic?

The Doctor: I'm going to find that creature.
Yaz: You can't do that on your own.
The Doctor: Always have done. Me and a Dalek? It's personal.

I wish I was better at life, Graham.

She once said to me,'If anyone ever asks about me after I'm gone, you tell them I was lucky. Tell them I gave someone life, I watched him grow, and I was proud.'

Graham

Lin/Dalek: Who are you?
The Doctor: I'm your secret conscience... not really, we both know you don't have one.

Lin/Dalek: Who has access to the archives?
Richard: Today, it's just me. Most secure digits in Yorkshire, that's what told me by a friend anyway. I probably shouldn't be telling you that. I'm new at this.
