"No Harry," James said, shaking his head. "He's been here before... also as a teenager, but he disappeared." The smile disappeared. Until he pushed Sirius again. "And as for Bree... she came from... well, she used to stay with Remus - the older Remus. But he disappeared, too. And there's a lot more complicated shit that I don't really need to explain. Basically, she's living with us because she likes us and we like her and she deserves a home. She's not related to us biologically, but she's ours. And she's inside if you wanna meet her. She's a lot like Moony. Reads all the time, is a good student. S'weird."
