"If Janus had told him to jump off a cliff, he'd probably have. Then again, Remus might have jumped off a cliff just for fun -but he'd have worn a clean shirt and a tie for him, and that had to mean something. Not that Janus would have asked. Maybe that was the reason Remus wouldn't have argued against it. He never tried to change him, not even a little."
And I'm done ! In case anyone asks where Remus' mustache is, I repeat, they're 13, and even his great willpower hasn't granted him facial hair yet. Janus has a lot of birthmarks, Remus has a black eye, they're matching.
