At first, the Doctor was tempted to examine Rose for damages she hadn't told him about. Then, briefly, he once more entertained the idea that none of this was actually happening and he'd gone completely around the bend, either from hitting his head too hard when he hit the floor or from the pain of the radiation tearing apart his body. Half of what Rose had just told him was impossible. More than half. Easily ninety percent of what she had said was completely and utterly outside the realm of possibility.
"You know, that Stephanie woman asked if I wanted her to come pinch me so I'd know this was real. I'm starting to seriously consider the possibility. You've just named how many fictional characters?

He flashed Rose a dim but genuine smile. "I'm having a bit of trouble taking it all in. It's brilliant, though. I mean ... It has to be. Harry Potter in the real world. Who wouldn't be impressed by that?"
He was rather more impressed by Rose, however. She'd become such a strong woman, and he was proud of her.
