"I'm probably going to call you James and Jamie sometimes by accident even if I try to go back to Elizabeth."
"I don't have a pen right now but if there's anything you're worried about forgetting I can write it down as soon as I do."
"I might just want eight hours with your notebook to write down everything in the Narnia files. If I'd written down everything in the Earth files right when you got the notebook, we'd have it in front of us now."
James realizes that she managed to forget what Chris's car looked like. Since Chris's car is a black-and-white Mini Cooper, it should really have been harder to forget than that. It comes back to her as soon as she sees it, but... she sighs unhappily.
"I'm annoyed that I forgot what kind of car Chris had," she says, getting up and proceeding to the car. Her hand remembers how to open the door even if she doesn't.
"Now, I know it's been a while, but I seem to remember you kids having backpacks when I dropped you off," says Chris.
"It's kind of a long story," says James. "I'm not sure if we should save it for when we get - home or not."
"About half an hour's drive," says Chris. "Is that enough time to explain what's going on?"
"We went through a magic door and saved a kingdom from an evil witch-queen and then spent the next fifteen years ruling it," says James. "I'm twenty-six now."
"Whatever spat us back out let me keep my magic notebook. So there's that for proof if you don't want to put us in separate rooms and get coherent too-complicated-to-be-rehearsed matching stories of the last decade and a half."
