Know how there's the whole thing of Sirius suspecting Remus to be the spy and that's why he never told Remus they changed Secret Keepers? Well, someone pointed out in some pre-DH speculation about the humorphous (sp?) charm, that Lockhart's book mentioned, that in some way shape or form "cured" a werewolf. And since we know that the things that Lockhart wrote about happened (just not done by him), that charm really exists and can do that.

So... what if there were rumors going around at the time of the first Wizarding War, about this charm, and Sirius got to wondering just how far Remus would go to be "cured"...

That would make an interesting fic.
