After a bunch of previouslies reminding us about the Slitheen, a worried man tells someone off screen that he's looked at the plans for something and they're unsafe. He pleads with Mystery Person to put a stop to it immediately before millions of people die. The camera pans around to show us Margaret, now in some position of authority. After establishing that he hasn't shared this information with anyone else, he turns away and says that the plans are almost as if someone wants the project to go wrong, wants to wipe the entire city off the map. He turns and screams because Margaret has taken off her skin suit and is all Slitheen-y. She attacks and we throw to the credits.
