DOCTOR: You have to be invited into my TARDIS, Conrad. To be special. But you? You're special, for all the wrong reasons. You see, I am fighting a battle on behalf of everyday people... who just want to get through their day, and feel safe, and warm, and fed. And then along comes this... Noise. All day long, this relentless noise. Cowards like you, weaponising lies, taking people's insecurities and fear, and making it currency. You are exhausting. You stamp on the truth, choke our bandwidth, and shred our patience. Because the only strategy you have is to wear us down. But the thing is, Conrad, I have energy to burn and all the time in the universe.

TEGAN: If you're trying to fob us off with shopping, it's working.

PARS: That’s what Time Lords have always done, Bevvakk. Build a great many doors. Then lock them all, and hidden the keys.

DOCTOR: Planets die! Planets die and species fall. Creation blinks once, billions of lives gone! You see if often enough, you start to understand. The greatest godlike power is useless, defenseless against it. All you can do, all you can ever do, in a million and one ways, in variation upon variation, is to improvise. Like a mad musician unable to stop hammering at the keys of a broken instrument, that's me!

(Returning to his car, Owen spots a young man.)

OWEN: Bernie Harris.

(He chases him through the streets.)

MARGARET: We're in Cardiff. London doesn't care. The South Wales coast could fall into the sea and they wouldn't notice. Oh. I sound like a Welshman. God help me, I've gone native.

OMEGA: The price we both paid for our ambitions was exile. Is that what you were going to say Doctor?

DOCTOR: Yes. Yes, I was.

OMEGA: I languished in the heart of a black hole for millennia. What did you have to endure?

DOCTOR: Um. The Brigadier, mostly.

VORG: Our purpose is to amuse, simply to amuse. Nothing serious, nothing political.
