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!
