Meanwhile, the Doctor is supervising the guys valeting the TARDIS: "Oi now, careful with that. Park it properly. No scratches." One of them squeaks and hands the Doctor a redemption card, on the back of which is written "Have a nice day" in an alien-looking but readable script. He watches them leave as though they are crazy, and stalks off. Behind him, several metal spiders scurry up the wall behind him. Cut to a few more running along the air vent, one of which jostles the camera. Good job and a nice detail, considering they're CGI.

Rose's spider scans her hand, but she's oblivious. The Doctor enters, sending the spider back into a vent, and sits down near her on a low wall: "What do you think, then?" Having just now processed the grandfather-as-tree, she moves on to the "slightly psychic paper," and jokes that she's getting there. The Doctor laughs, and she pauses before trying to express her discomfort: "They're just...so alien. The aliens? Are so alien. You look at 'em...and they're alien." The Doctor cracks, "Good thing I didn't take you to the Deep South." (I'm told her accent is Sarf Landen, or a good try at it anyway.) Rose considers the Doctor, trying to put him into the context of this universe where there are no people, only aliens: "Where are you from?" She doesn't know it's the one question the Doctor can't ever answer again. He swallows and says in a light tone, "All over the place." He won't look at her.

"They all speak English," Rose says of the revellers, but the Doctor explains that it's "a gift of the TARDIS" -- a "telepathic field" that translates inside the brain. Rose is not at all cool with the TARDIS being in her brain. She's been on this adventure for, like, a half-hour, remember. She just made her choice and the drawbacks keep appearing like this; you'd freak, too: "Your machine gets inside my head. It gets inside and it changes my mind, and you didn't even ask?" The Doctor's thrown: "I didn't think about it like that." Now she's pissed. "No! You were too busy thinking up cheap shots about the Deep South! Who are you then, Doctor? What you called? What sort of alien are you?" Stop it. Stop it. Stop it. "I'm just The Doctor," he tells her. He sits up and turns his back on her. "From what planet?" she presses. Stop. "Well, it's not as if you'll know where it is!" he tells her. She presses and he presses back, both of them getting more and more intense. She's understandably curious, but Rose: could you please read the room? "This is who I am, right here, right now, all right?" he tells her. "All that counts is here and now, and this is me!" That's the answer. He just answered her and she doesn't even know it. I don't even know if he knows it -- I think he'd say he's being defensive, if you were watching it with him, but that usually ends up being more true anyway. "I'm here too because you brought me here, so just tell me!" she demands. He gets up and goes to the window, stomping petulantly. Earth Death in twenty minutes.
