Love the story! Have you considered the possibility that the new strain of the werewolf curse/disease could be like the super!vampire virus in the Blade movies? In other words, not only could Harry/Ginny infect humans but they could infect existing werewolves with the new strain. If they were then able to learn some measure of control without the use of the wolfsbane potion, it could lead to a real revolution in the way werewolves are treated.

I think the new strain is more of a retrograde virus, a disease that actually somehow evolved back closer to the original strain. As for what the original strain is, you'll have to read the story. In regards to the abilities of the new werewolves, it goes back to the source of the werewolf disease.
Thanks for the review!
