It didn't take long for Jill to go to her granny's house, who fortuitously lived on the house that was on the other side of the street. The teenage werewolf rang and patiently waited at the door.
Her maternal grand-mother, Juliana, had always knew her now deceased husband, Raymond, had been a werewolf, he had demonstrated it to her as soon as things became serious between them. It's probably because her dear Ray, that lovable goofball, had acted more like a dog than a wolf during his demonstration that she had accepted him. She's sad to admit it, but if he had acted as a wolf she might have thought he was the same kind of monsters found in horror stories.
While Ray loved to goof around, he could be serious when needed, and had explained to her how the curse came from his own father, a man he knew nothing of beside that he was a womanizer, considering Ray's mother like nothing else than and ‘used’ conquest, probably forgotten once she was too pregnant to abort, but not before trowing the bomb that he had been cursed to turn into a werewolf, and their future kid might share the curse with him. From what Ray's mother had said to her son, the man was totally flippant about it, like he didn't care. "Of course mom didn't believe it until my brother and me changed for the first time." had admitted Ray.
Then they had transformed and, after a bit of digging Amanda, Jill's great grand-mother, had discovered the curse was made to be transmitted to her ex-boyfriend's first-born, who would in turn transmit it to their own first born… Except that each time the mother was different, the counter war 'reinitialized', meaning that while the women of the family could only give birth to one werewolf, the men could have one for each women they have kids with. While Ray stayed faithful to Juliana, who know how much half-siblings he had, and how much of the male ones where sleeping around? And Ray didn't have much illusion that most of them were as accepting of his ‘curse’ than he was.
Paradoxically, his acceptance of the curse caused him to be rejected by his family who, height of stupidity, accepted and respected his brother for tying to get rid of it, ‘helping’ hin deal with it. As you could except, It didn't end well.
So Juliana knew about Ray's curse and its history, she also knew Jane and Jill were cursed too, she was even the one who pushed her grand-daughter to speak of it with her father. But Juliana didn't know Jane rejected the curse, just like her uncle, and never spoke of it with her husband. I'll let you imagine how surprised she was to see Jill on her doorstep, grumbling, with a duffel bag on her shoulder, and how terrified she was once the situation was explained to her.
While Juliana was happy to have her grand-daughter until things were resolved with Jane, she was a bit worried. While it had took time for her to recover after Ray's died of old age, she had finally found love again in Danyor, a man of gypsy descent, who even had with her a couple days back. But Dany didn't know about the werewolves in her family, how could she say it without making herself look like a madwoman? "Do you want me to demonstrate the curse to him, granny?"
