The Doctor tries to answer Rose's first question before she rushes on. "No."

But it came out so quietly, that he doubts she heard him.

"I'll be fine."

Nothing can be worse than his Confession Dial. But Rose is still going on... and on. And he doesn't know how to stop her. He wonders how young she is. Given the way she's talking, and how she accepted his new face, he figures she's sometime after the Sycorax, but he can't just know by looking at her.

"Rose. I'd like a tour, but stop trying to fix me."

He's pretty broken at this point and the only thing that will fix him is the TARDIS.
