Jackie hears the TARDIS coming and also runs down the street, and Jackie and Mickey fall into each other's arms yelling about Rose. Jackie: "She's alive, Mickey! I said so, didn't I? She's alive!" They look frantically around, wondering when the TARDIS will actually appear, and I'm all, "Wait, is that the sound? Like rusty cables?" And then abruptly the TARDIS jumps into the air above their heads, ricocheting from building to building, making a mess. Careening, like the Doctor, with his eyes like wild pearls.
The Doctor throws the TARDIS doors open and stares out, ranting: "Here we are, then! London! Earth! The Solar System! We did it!" He stumbles into the light, staring up at the buildings, and then notices Jackie and Mickey, looking at him, uncomprehending. He throws himself upon them and talks nonsense, mumbling and trying to remember what he wanted to tell them, leaning against them and holding himself up by their shoulders. "OH!" he screams, making them jump. "Merry Christmas!" And with that, he falls to the ground. Rose joins them and asks what happened to him; Mickey and Jackie are like, "Don't care, where's Eccleston?" Rose tries to explain about the Doctor and things, only instead of explaining, she's just like, "That's him, right in front of you. That's the Doctor." Nothing of him that doth fade but doth suffer a sea-change, into something rich and strange. Which gives Jackie the opening she needed for the credits break: "What d'you mean, that's the Doctor? Doctor who?"
After the credits, we join the Doctor in bed, where he is wearing striped pajamas, and Jackie joins Rose in the bedroom, carrying a stethoscope. This is the "healing of Albion" episode par excellence in a lot of ways, given that the world is saved by a cuppa, so it's nice to have this little scene where Rose doctors the Doctor. Even though they're playing Doctor, because a stethoscope -- even one ganked from "Tina the Cleaner's lodger," who is a medical student (a gorgeous black one with pineapple hair? Only time will tell) -- does not a Doctor make. But Rose hooks her ears in there anyway even as Jackie's complaining that they should take him to the hospital. Rose explains that they'd immediately lock him up and dissect him, which I guess gets over the plot hump except for how it's totally the Doctor and he would beat their asses, except maybe she's referring to his coma. "One bottle of his blood could change the future of the human race," Rose says. That's all there is this Christmas: blood, and words, and good English tea. Rose shushes her mum and checks both of the Doctor's hearts, which are beating. They discuss how the Doctor has two hearts, and then so that we know Jackie's kind of awesomely slutty, she asks if he's got two of anything else, and makes to peek at his Underoos. Rose tells her in no uncertain terms to stop molesting the alien life form, and first she and then worried Jackie leave the room. A little bit of God slips out of the Doctor's sleeping mouth, and up into the sky.
