DOCTOR: How much are they paying you?

ROSSINI: Come, come, Doctor. Gentlemen don't discuss money.

DOCTOR: Nonsense, gentlemen never talk about anything else.

ROSSINI: (Italian) Who the heck are you? Well?

MASTER: I am usually referred to as the Master.

ROSSINI: Oh? Is that so?

MASTER: Universally.

JO: It's all right. I've dealt with it.

DOCTOR: Dealt with it? You've ruined it!

JO: But your bench was on fire.

DOCTOR: Three months delicate work and now look at it, you ham-fisted bun vendor.

JO: But this whole place might have gone up in flames.

DOCTOR: My dear young lady, steady state micro-welding always creates more smoke than fire.

JO: A translucent polyhedron, eight and a half inches in diameter.

(The Doctor grabs the file.)

DOCTOR: Well, that's the Nestene's energy unit. It should never have left this building.

JO: Apparently they wanted it for a special display. The Brigadier signed the authorisation.

DOCTOR: The Brigadier's an idiot!

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.

DOCTOR: Do you know, Jo, I sometimes think that military intelligence is a contradiction in terms.

JO: I'm your new assistant.

DOCTOR: Oh, no.

JO: The Brigadier sent me along to introduce myself, Doctor. Josephine Grant.

DOCTOR: How do you do, Miss Grant? I really don't think you're suitable.

MASTER: I hope I'm not interrupting anything important.

DOCTOR: No, no, indeed not. You've come here to kill me, of course.

MASTER: But not without considerable regret.

DOCTOR: How very comforting.

MASTER: You see, Doctor, you're my intellectual equal. Almost. I have so few worth opponents. When they've gone, I always miss them.

DOCTOR: How did you get in here?

MASTER: Oh, don't be trivial, Doctor. I see you've been working on the Nestene autojet. My own small contribution to their invasion plan.

DOCTOR: Vicious, complicated and inefficient. Typical of your way of thinking.

MASTER: Now, come, come, Doctor. Death is always more frightening when it strikes invisibly.
