TEXT: A recap of 1x04 "Aliens of London" and 1x05 "World War Three". Six month later. INT. LORD MAYOR'S OFFICE Mr Cleaver paces the office. MR CLEAVER (anxiously): I've checked the figures. I've checked them again and again. ALWAYS the same result. The design is not safe. It could result in the death of millions. I beg of you... stop the project right now, before it's too late. MARGARET: Well. Goodness me. Obviously, Mr Cleaver, you're the expert... MR CLEAVER: Then... you'll stop it? MARGARET: Seems I have no choice. (Stomach rumbles noisily, an apologetic smile). Oh... do excuse me. Civic duties leave little time for a sandwich. MR CLEAVER (urgently): But you promise you'll stop it, today? MARGARET: Well of course. Nothing is more important than human life... Her face hardens, and Cleaver looks slightly worried. She makes an effort to lighten her tone. MARGARET (CONT'D): What do you take me for? Some sort of maniac? MR CLEAVER: Why, no... MARGARET: Am I right in thinking you've shown your results only to me? MR CLEAVER: Just to you. No one else. MARGARET (smiles): Wise move. Mr Cleaver, clearly very relieved, takes off his glasses and wipes his eyes, fatigued. MR CLEAVER: I can't tell you Mrs Blaine, this is such a weight off my mind. I've barely slept. I couldn't believe my own readings. He whips a hanky out of his pocket, his backed turned to Margaret, who looks darkly at him and slowly raises a hand to her forehead... MR CLEAVER (CONT'D) The scale of it - destruction like the British Isles has never seen before. He cleans his glasses on the hanky
SUMMARY:
The Doctor, Rose, and Jack visit Cardiff to refuel the TARDIS at the rift, and Mickey meets them there. They discover that the Slitheen impersonating Margaret Blaine is now the mayor of Cardiff, and they capture her, suspicious of what she has done. The Doctor sees that she has created a nuclear power plant designed to open the rift and destroy Earth, and a device she would use to flee. Margaret objects to being taken back to her home planet, as she is considered a criminal there. After several failed attempts in killing the Doctor, Margaret requests to be taken to another planet. Jack sees the opportunity to use Margaret's extrapolator to speed up recharging the TARDIS, but this proves to be a trap as it was meant to send the nearest alien power source to the rift. As an earthquake strikes Cardiff, Margaret looks into the heart of the TARDIS, which gives her a second chance at life, restoring her back into an egg.
