IDRIS: The Lord Mayor says thank you for popping by. She'd love to have a chat, but, er, she's up to her eyes in paperwork. Perhaps if you could make an appointment for next week?

DOCTOR: She's climbing out of the window, isn't she?

IDRIS: Yes, she is.

DOCTOR: You let one of them go, but that's nothing new. Every now and then, a little victim's spared because she smiled, because he's got freckles, because they begged. And that's how you live with yourself. That's how you slaughter millions. Because once in a while, on a whim, if the wind's in the right direction, you happen to be kind.

MARGARET: Only a killer would know that. Is that right? From what I've seen, your funny little happy go lucky little life leaves devastation in its wake. Always moving on because you dare not look back. Playing with so many peoples lives, you might as well be a god. And you're right, Doctor. You're absolutely right. Sometimes you let one go. Let me go.

CATHY: The deaths, The number of deaths associated with this project. First of all, there was the entire team of the European Safety Inspectors.

MARGARET: But they were French! Its not my fault if Danger Explosives was only written in Welsh.

CATHY: And then there was that accident with the Cardiff Heritage Committee.

MARGARET: The electrocution of that swimming pool was put down to natural wear and tear.

CATHY: And then the architect?

MARGARET: It was raining, visibility was low. my car simply couldn't stop.

CATHY: And then just recently, Mister Cleaver, the government's nuclear adviser.

MARGARET: Slipped on an icy patch.

CATHY: He was decapitated.

MARGARET: It was a very icy patch.

JACK: According to intelligence, the target is the last surviving member of the Slitheen family, a criminal sect from the planet Raxacoricofallapatorious, masquerading as a human being, zipped inside a skin suit. Okay, plan of attack, we assume a basic fifty seven fifty six strategy, covering all available exits on the ground floor. Doctor, you go face to face. That'll designate Exit One, I'll cover Exit Two. Rose, you Exit Three. Mickey Smith, you take Exit Four. Have you got that?

DOCTOR: Excuse me. Who's in charge?

JACK: Sorry. Awaiting orders, sir.

DOCTOR: Right, here's the plan. (pause) Like he said. Nice plan. Anything else?

MARGARET: We're in Cardiff. London doesn't care. The South Wales coast could fall into the sea and they wouldn't notice. Oh. I sound like a Welshman. God help me, I've gone native.

DOCTOR: Here she is.

ROSE: She's an egg?

DOCTOR: Regressed to her childhood.

JACK: She's an egg?

DOCTOR: She can start again. Live her life from scratch. If we take her home, give her to a different family, tell them to bring her up properly, she might be all right!

JACK: Or she might be worse.

DOCTOR: That's her choice.

ROSE: She's an egg.

DOCTOR: She's an egg.
