Don't mention Peter, Peter's not important, we never think of Peter, I forgot about - "Peter." The little bastard. Not Remus at all, not the obvious spy, of course it wasn't the obvious spy. They'd spent half an hour screaming at each other and it had been Wormtail all along, scurrying off, saying nothing. Not the werewolf (too much a librarian), not the Black (too much a Gryffindor). The boy who turned into a rat because he liked to know things, because he liked people's secrets, because he liked to be a spy ... how had they not noticed? How had they not seen -
