"Yeah. Dad made it for me when I was little." She touched the picture of her dad. "He and mum don't have a very safe job, and if something happened to them, he wanted me to have something of them to remember. And I travel with them more now, and I have to keep with me anything I really want to keep. So I always carry the book." She flipped it to the next set of pictures.
"And there's Uncle Jack, and Uncle Doctor, and then there's Aunt Solfi and Aunt Ami next, and then Ewythr Ianto and Aunt Tosh, and then Doctor Brat and Aunt Gwen. And I need to get a new picture of Uncle Doctor, 'cause he doesn't actually look like that any more, but Mum wouldn't get a new one, 'cause she's really, really upset he went and changed his face and didn't tell her before showing up with it."
