Trish grabs all the pencils from around the house, explaining again that Chloe usually got the brunt of her father's temper: "When he'd had a drink. The day he crashed the car, I thought we were free..." Rose hands her a bunch of pencils. "I thought it was over," adds Trish. Rose asks if they ever talked about it, and Trish admits she didn't want to: "Maybe that's why Chloe feels so alone, because she has all these terrible dreams about her dad, but she can't talk to you about them," says Dr. Rose. The Doctor describes Chloe and the Isolus again as "two lonely kids who need each other." Which is the usual out he gives alien threats, but it's kind of stagnant this time. Kinda sour. "And it won't stop, will it, Doctor? It'll just keep pulling kids in." Jackie. Mickey. LINDA. "It's desperate to be loved. It's used to a pretty big family." Rose asks how big: "Say around...four billion?" Rose and Trish go quiet at this; Rose looks at the TV. The Olympiad.

Upstairs, Chloe's watching. "The queues started a week ago for those desperate enough to be inside, although lots of them expected a capacity crowd of eighty thousand..." There's another sound from the wardrobe; Chloe jumps and then stands up.

The Doctor shrugs into his coat, leaving Trish's house with Rose: "We need that pod." Rose asks if it wouldn't be destroyed by now, but he figures it's been sucking heat from the neighborhood all week, so maybe it's doing better. Rose sees Chloe looking down at them from the window. "It must be close. It should have a weak energy signature that the TARDIS can trace. Once we find it, then we can stop the Isolus." The Wolf, the gap, the loneliness? Reality, red in tooth and claw? The rules of the real world? You can try.
