After a bit, Rose follows the Doctor down to the window: "All right, as my mate Shareen says: don't argue with the designated driver." The Doctor smiles, but not in his secret back-turned way; more bitterly than that. It still stings. Rose -- when it doubt, all that -- pulls out her cell phone and makes a joke about how she can't call for a cab. The Doctor -- on a dime, this guy -- takes the phone and mumbles, "With a little bit of jiggery pokery..." He takes off the phone's back panel and does stuff to it. Rose joshes him: "Is that a technical term, 'jiggery pokery'?" He jokes that he "came in first in jiggery pokery," and asks how she did: "Nah, failed hullabaloo." He hands the phone back to Rose, and nods at her confusion.

Rose dials her mum, and we find ourselves back in Jackie's kitchen in 2005 (And, as an eagle-eyed poster pointed out, hours or days before the first episode began, not "now." Which is interesting, because: time travel. There's no "now" to be had anymore. Wherever Rose is, that's "now.") Jackie's putting laundry in the machine as she natters at her daughter: "Oh, what is it? What's wrong? What have I done now? Oh, this red top's falling to bits! You should get your money back." Rose laughs, again, to hear her mother's voice. "Go on!" Jackie demands. "There must be something, you never phone in the middle of the day!" Rose just smiles and giggles, loving her mother from so far away. "What's so funny?" Jackie asks. Rose shakes her head: "Nothing! You all right, though?" Of course she is. Rose asks what day it is, and Jackie's a scream: "Wednesday. All day. You got a hangover? Oh, I tell you what, put a quid in that lottery syndicate, I'll pay you back later." Rose mentions that she might be late coming home, and when Jackie asks if she's okay, Rose responds that she's "Fine! Top of the world!" The Doctor laughs, and the Tylers ring off. Rose lowers her phone, stunned. The Doctor: "Think that's amazing, you want to see the bill." But Rose is having deep thoughts. "That was five billion years ago. So...she's dead now. Five billion years later, my mum's dead." The Doctor calls her a "bundle of laughs," but before she can process how alone they both actually are, Platform One gives a shudder. The Doctor, nervous and ecstatic in equal amounts, relishes it: "That's not supposed to happen!" I like the Doctor, don't you?
