ROMANA: Yes, they taught me at school how to stop my hearts.

TYSSAN: Hearts? How many have you got?

ROMANA: One for casual, one for best.

DAVROS: I have failed!

DOCTOR: Yes. What does it feel like?

K9: coughs

DOCTOR: Do that again.

K9: coughs again

DOCTOR: Say "ah".

K9: scratchy "ah" sound

DOCTOR: Ah! Laryngitis! How can a robot catch laryngitis? I mean, what do you need it for?

DOCTOR: Hold it, hold it. Now, tell them what I've got here.

DAVROS: He is holding a primed explosive device.

DOCTOR: And one false move, and it goes right down inside his chair. I'll turn Davros and his life-support system into scrap metal. Now spack off!

DOCTOR: All elephants are pink. Nellie is an elephant, therefore Nellie is pink. Logical?

DAVROS: Perfectly.

DOCTOR: You know what a human would say to that?

DAVROS: What?

TYSSAN: Elephants aren't pink.

DAVROS: Bah. Humans do not understand logic.

ROMANA: They're not slaves to it like the Daleks or the Movellans.

DALEK: The workers have been released.

DOCTOR: Good, good. Now, I'll need one minute to get clear. Get back! I told you this was life insurance. I've adapted the device to explode by remote control.

(The Doctor sticks the bomb onto Davros' life support.)

DOCTOR: All I have to do is squeeze my sonic screwdriver and boom, boom, Davros.

DAVROS: You need not elaborate, Doctor.

DOCTOR: Just so long as you've got it clear.

DOCTOR: Well. Well, now we've a little time to ourselves, I'll fill you in on some of the events that have taken place during the centuries you've been, er, dozing.

DAVROS: Well?

DOCTOR: Well, Arcturus won the Galactic Olympic Games. Betelgeuse came a close second. The economy on Algo's in a terrible state due to irreversible inflation...

DAVROS: Doctor!

DOCTOR: What? Yes?

DAVROS: Do you believe your puny efforts can change the course of destiny?

SHARREL: Disfunction or death, as you know it, only occurs in us with massive circuitry disturbance. We are infinitely superior.

DOCTOR: Are you really?

SHARREL: We function logically.

DOCTOR: My condolences to you.

DAVROS: Since my entombment, I have no knowledge of the advancement of my Daleks. Of course they have achieved great things.

DOCTOR: Oh yes, oh yes. They've wreaked havoc and destruction, destroyed countless innocent lives

DAVROS: Only the beginning! Now I have returned, the campaign will begin in earnest. I have slept but now I have awakened, and the universe will be sorry.

DOCTOR: Davros, you. I have slept but now I have awakened and the universe will be. You're misquoting Napoleon! One day I'll tell you what happened to him, too.

DAVROS: Supreme Dalek. Pah. That is a title I shall dispute most vigorously. I created the Daleks. It is I who will guide their destiny. I am the Supreme Commander!
