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?
Brigadier: If I accept all that, there are still a lot of things… By the way, this is Miss Shaw.
Doctor: (looks at her and moves his eyebrows a lot) That’s Delphon for “how do you do”.
