- The Doctor: But the Master tracked me down, and now he wants me dead, whereas I am a big fan of being alive.
- The Doctor: I know you think I'm mad, but give me five minutes and you'll think I'm the sanest person alive. Okay, that was an overstatement.
- Daniel Barton: Today, I'm here to say thank you to those of you all round the world who've made our achievements possible, to everyone who, over the years, has given us everything. We gave you pieces of plastic and circuitry and games and you handed us, me, my company, total access to your lives, what you buy, where you go, who you text, what you text, every thought and photo and post, every credit-card number, every birthday, every memorable place and all your mothers' maiden names. So thank you for carrying our cameras in your pockets and putting our microphones in your bedrooms, for signing up your kids, handing them our devices. We told you, "Of course your lives are private, of course your data's safe. And you believed us. You kept clicking Agree. And now we can do anything. I can send a text to every device on this planet.
- The Doctor: What are you? Pathways? Signals? Synapses? I could be inside something. Oh, I hope it's not a liver. I hate being inside livers. People always get so offended. "What are you doing in my liver again?"
- Graham O'Brien: Ryan's right. We carry on doing what the Doc would want us to do.
- Ryan Sinclair: I'm sorry, did you just say, "Ryan's right"?
- Graham O'Brien: Yes, I did! Enjoy the moment, son. You won't hear it often.
- The Doctor: These are the dark times. But they don't sustain. Darkness never sustains even though sometimes it feels like it might.
- Ryan Sinclair: Your boss thinks we're stupid. She made the call knowing that you'd come for us. And now we're taking your phones and we're going to raid your GPS. How's that for smart?
- Yasmin Khan: Ryan! Don't tell them the plan!
- Ryan Sinclair: Oh, yeah. Sorry, I got a bit carried away.
