MONK: This is your plan? You want to rob an intergalactic master criminal?

MISSY: Well, excuse me. I am an intergalactic master criminal too, y'know. The clue's in the name.

MONK: Come off it.

MISSY: Who threatened the whole universe with destruction using the science of Logopolis? Who overwrote all human DNA with their own? Who hijacked a Concorde dressed up as a sort of, you know, dodgy looking magician?

MONK: Yes, why did you do that?

MISSY: Well, not every plan is a winner. But if we play this one right, we'll get a tank full of plutonium and I'll have got hitched to one of the universe's most terrifying gangsters. I mean think of the size of the divorce settlement!

STEVEN: Good day. We're looking for...

MONK: Indeed, we're all searching for something. Some like myself seek it in the peace and solitude that repose behind these monastery

STEVEN: We are looking for a friend of ours!

DOCTOR: So that's it! You're a time meddler! No wonder you wanted to get rid of me. And what are you trying to get up to this time?

MONK: I'm sure you'll approve, Doctor.

DOCTOR: Are you quite mad? You know as well as I do the golden rule about space and time travelling. Never, never interfere with the course of history.

MONK: And who says so? Doctor, it's more fun my way. I can make things happen ahead of their time.
