So the child has a desire, and pictures on the walls, and always the same voice: "Are you my mummy? I want my mummy! Are you my mummy?" Rose and the Doctor have heard the voice; it's only the Doctor that knows what it means, at this moment. Rose: "Always 'Are you my mummy?,' like he doesn't know. Why doesn't he know?" The Doctor thinks, almost there, bending under its sad weight.
Mr. Lloyd shuts the door on himself and Nancy at the dining room table. He leans on the table: "The police are on their way. I pay for the food on this table. The sweat on my brow, that food is. The sweat on my brow. Anything else you'd like?" Nancy smiles, a Doctor-worthy smile, something bright and sharp underneath the goofy grin: "Yeah. I'd like some wire cutters, please. Something that can cut through barbed wire. Oh, and a torch." And the face on Mr. Lloyd! "Don't look like that, Mr. Lloyd...I've been watching this house for ages. And I'd like another look 'round your kitchen cupboards. I was in a hurry the first time. I wanna see if there's anything I missed." Mr. Lloyd starts with the "food on my table" speech again, and she shuts him up tight: "It's an awful lot of food, isn't it, Mr. Lloyd? A lot more than on anyone else's table. Half this street thinks your missus must be messing about with Mr. Haverstock the butcher. But she's not, is she? You are." It's a matter of context. Just ask old Algy, or Captain Jack: what's scary now isn't scary then. What's social poison, given twenty years, or fifty? There are so few absolutes that you can count on absolutely, but here's one that's strong for me: the future is always, always better. Captain Jack could tell Mr. Lloyd how it'll be later; but maybe Nancy knows a bit about this, too. About being stuck in your context, about keeping secrets. Maybe that's what makes her sensitive to Mr. Lloyd's not-all-that-terrible secret -- maybe there's a brotherhood here that earns her this leverage. Maybe she's already paid for this knowledge and we just don't know it yet. Triumphant now, Nancy goes on: "Wire cutters. Torch. Food. And I'd like to use your bathroom before I leave, please." And the biggest smile forms on her, again: "Oh, look! There's the sweat on your brow." I love this girl. It wasn't Captain Jack that doubled the Doctor; it was always her. This lioness. Nancy opens the dining-room door for Mr. Lloyd, and stands at attention.
