I wonder if he was young, not much older than her.

I remember when I used to go out with people from school and you'd have so many people coming from different areas you'd end up with friends of friends of friends so you'd end up with people you don't actually know.

Maybe he charmed his way in by pretending to be mates with her mates from school or whatever. They haven't caught him so he might turn out to be from an extended group of friends.
