The TARDIS intimidates him, with its huge levels and confusing corridors and the slightly unnerving fact that it's bigger on the inside. Rose concludes the tour where they began, at the main level.
"So," Rose says. "You and him, you just...travelled through time together?"
Ando thinks the question rather forward for two relative strangers to discuss, but he decides to answer anyway. "Yes. But not in something this special. Not in a ship. A real UFO!"
"Ship's not really that special. Sometimes the Doctor needs to smack the console a bit to make it work. It's not like thinking your way there. Just close your eyes and whoosh, that's amazing!"
"No, not very amazing. I did not believe him, at first. I doubted his power and his mission, because I was stuck in my life. My job, my computer. That was my life. Every day, doing the same things, and I thought I had a good life. That was all I knew, back then."
"And then one day," says Rose, "Something happened. He showed you things that you thought were once impossible. Showed you his life and his world and he said 'come with me'. And you did."
"Yes. He had a comic book from five weeks into the future, and there, inside, was us. Our faces. Our words. Printed on paper."
She laughs. "Living shop-window dummies tried to kill me."
"I think," Ando says with a half-grin, "It was easier to convince you than it was to convince me."
