BRIGADIER: Nonsense. What you need, Doctor, as Miss Shaw herself so often remarked, is someone to pass you your test tubes and to tell you how brilliant you are. Miss Grant will fulfil that function admirably.

BRIGADIER: Still sceptical?

LIZ: Of course. I deal with facts, not science fiction ideas.

BRIGADIER: Miss Shaw, I'm not a fool. I don't chase shadows. What you don't understand is that there might, there is a remote possibility that outside your cosy little world other things could exist.

LIZ: No need to get tetchy.

BRIGADIER: Well, sometimes you can be very aggravating.

LIZ: Me? What about you? You really believe in a man who's helped to save the world twice? With the power to transform his physical appearance?

BRIGADIER: I'm not sure yet. It may not be the same man.

LIZ: An alien who travels through time and space in a police box?

BRIGADIER: Oh well, at least he won't get very far.

LIZ: You mean, before your men shoot him again?

BRIGADIER: I don't find that funny. Without this machine, the Doctor's stuck. He can't leave Earth.

LIZ: You were about to open it?

BRIGADIER: Yes.

LIZ: I think you should. There might be a policeman locked inside.
