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.
Chloe moves away from the window; Trish is downstairs telling somebody that Chloe's running a fever. Chloe sneaks out without Trish's noticing. "We've got a Doctor. He said he can help her."
Chloe follows the Doctor and Rose to the TARDIS, drinks in the image of it. "We can scan for the same trace we picked up from the scribble creature. Just need to widen the field a bit..." Inside, the Doctor fumbles with a device while Rose ponders: "You knew the Isolus was lonely before it told you. How?" The Doctor pushes Rose out of his chair and cutely sits down in it: "I know what it's like to travel a long way on your own. Give me the [technobabble technobabble]...thing in your left hand!" he says, nodding at it. She chews her gum and considers him: "Sounds like you're on its side." He admits that he can sympathize. "The Isolus has caused a lot of pain for these people," says Rose, and the Doctor gets fussy: "It's a child!" You wish. He blows on the device: "That's why it went to Chloe, two lonely mixed-up kids." Rose says it's more like a temper tantrum because it can't get its own way, and again, the Doctor gets defensive: "It's scared! Come on, you were a kid once." Yeah, but she grew up. What's your excuse? "Yes! And I know what kids can be like. Right little shiiii...terrors."
Back in her bedroom, Chloe has cleverly stashed some pencils down a dolly's neck. That was when I decided I looooved Chloe Webber. She takes them out, moving fast.
The Doctor, grotesquely, holds out his hand for Rose to spit her gum in it, and then sticks it onto his makeshift device. I don't know how you do things over there, but do not think that this behavior will fly in the States. Not on my watch, bucko. "I've got cousins. Kids can't have it all their own way. That's part of being a family." Please, please listen to her. "What about trying to understand them?" asks the Doctor. So not the point. Rose smiles, turning away: "Easy for you to say. You don't have kids." He shrugs: "I was a dad once." Predictably, Rose wigs about that and gets pretty useless for the next stretch. Ignoring her questions, the Doctor holds up the device, complete: "I think we're there!" He muses: "Fear. Loneliness. They're the big ones, Rose. Some of the most terrible acts ever committed have been inspired by them. We're not dealing with something that wants to conquer or destroy." Rose can barely hear him, but the Doctor keeps going: "There's a lot of things you need, to get across this universe. Warp drive, wormhole refractors..." Rose holds her hand out as he's speaking: "You know the thing you need most of all? You need a hand to hold." The Doctor notices Rose's outstretched hand and takes it, grinning. Even the TARDIS almost fucking pukes, but Rose just laughs at him -- the gorgeous laugh she only seldom lets loose. "No! Look, I'm pointing." There's a map on the screen, and a flashing white light on the street. "It's the pod! It is in the street! Everything's coming up Doctor!" he shouts. Um, it was obviously going to be in the street where the cars were dying. Did they really need to get their gross saliva all over the place to know that? Rose follows after a moment, still slightly distracted. Right little shits.
