VIZIER: Kowtow. Kneel upon the ground and touch your forehead upon the floor three times.

DOCTOR: (Outraged.) I shall do no such thing!

VIZIER: Kublai Khan is the mightiest man the world has ever seen. Not to pay him homage will cost you your head.

DOCTOR: Well, if it breaks my back, then he can take all of me! So why waste time on small items?

BARBARA: We failed.

DOCTOR: Yes, we did. We had to.

BARBARA: What’s the point of travelling through time and space if we can’t change anything? Nothing. Tlotoxl had to win.

DOCTOR: Yes.

BARBARA: And the one man I had respect for, I deceived. Poor Autloc. I gave him false hope and in the end he lost his faith.

DOCTOR: He found another faith, a better, and that’s the good you’ve done. You failed to save a civilisation, but at least you helped one man.

Dalek: You slaves will now have the privilege of hearing our great Emperor talking to you from our planet.

Dalek Emperor: Greetings from Skaro. You people of Venus have been freed from the bondage to your Earth masters!

IAN: Maybe you have succeeded. Maybe we are where you say we are. But I remember an occasion when you took us home once before.

BARBARA: Yes, and we met Marco Polo.

DOCTOR: Entirely different circumstances! I’m rather tired of your insinuations that I am not master of this craft. Oh, I admit, it did develop a fault, a minor fault on one occasion, perhaps twice, but nothing I couldn’t control.

IAN: I know that. Of course you’re in control. You’re always in control. And I’m sure you could revisit us at any time.

DOCTOR: Very simple. Quite simple.

IAN: Exactly, quite simple. But you have your important researches to complete. You may not find the time. There’s a chance that we won’t meet again. Don’t you think it would be better if we parted under more friendly circumstances, say over a drink?

DOCTOR: Yes. Yes, well perhaps, since you put it that way, an hour or two won’t come amiss. Susan, bring my stick will you?

SUSAN: Yes, Grandfather?

DOCTOR: I’m going to see Ian and Barbara back home safely.
