Here's the million galleon question - what was her name? The only reason he even bothered to stop was because he recognized her since she was also in Ravenclaw.

So what was he going to do? Wing it.

"Pretty good," he said, leaning in the doorway while he watched her stretch out and look bored with being on the train. "I mean, it could've been better. It's hard talking to your family about what goes on since they don't really get it. I love them, I just find the Muggle world so BORING now." She said something about being jetlagged, so obviously she had done some Muggle traveling this summer too. "Where were you off to?"

Ashley? No, too common. Riley? No. But it definitely ended in "ley", he knew that much. Maybe he'd just make up a nickname for her.
