the wolf blood was strong enough that, if every grown werewolf is half full of it—half man, half wolf—and they throw pups with some human, then that kid should just be a quarter wolf, right? Wrong. Because the wolf blood, it’s hungry. Even a quarter is enough to really be half. That’s just the way it is. But if a werewolf and a werewolf try to start a family, well. The pups live, but they never shift up to two legs. Being born half full of wolf blood, it’s like being nearly all the way wolf. There’s not enough man in there to rise.
