Maybe the new werewolves will understand what people are saying and can react to what is said (higher than human intelligence). The number one priority is their mate then leadership in the pack.
Have the new werewolves only able to infect another person if they want to. In others you can't take the blood and infect others to create a whole new army.
Eventually able to change at will as they slowly come to acceptance and better self control.
Love the story.

I do have some plans for the werewolf strain that Harry and Ginny has. It's kind of based on the AIDS/HIV virus or rather how it got passed on from chimps to humans. I've been trying to mesh the pack social structure seen in real wolves to the werewolves JKR hammered out.
As for the werewolves infecting those they want to, that's already been dealt with due to the event surrounding Ginny's infection. If there's a way for them to actual gain control over it is something I have to think about rather if the virus is in the blood or other bodily fluids.
For the third thing, that goes back to how the werewolf strain started but you're heading on the right track.
Thanks for the reviews!
