Classic Who Watch | The Daemons

Master: Doctor, why don’t you come with me? We’re both Time Lords, we’re both renegades. We could be masters of the galaxy! Think of it, Doctor. Absolute power! Power for good. Why, you could reign benevolently, you could end wars, suffering, disease. We could save the universe.
Doctor: No, absolute power is evil.
Master:  Consider carefully, Doctor, I’m offering you a half-share in the universe.

Doctor: You’ll never understand, will you? I want to see the universe - not rule it!

Brigadier: I have a lot of questions.
Doctor: It’s no good to ask me questions. I’ve lost my memory, you see.
Brigadier: How do I know you’re not an impostor?
Doctor: You don’t, you don’t. Only I know that. What do you think of my new face? I wasn’t too sure about it myself. It sort of grows on you. Very flexible, you know. Could be useful on planet Delphon, where they communicate with their eyebrows. That’s strange. How did I remember that?

Doctor: (looks at her and moves his eyebrows a lot) That’s Delphon for “how do you do”.
