A New Breed (TVD/Teen Wolf)

My name is Julie McCall. Twin of Scott McCall, best friend to Stiles Stilinski. Our families decided to take a trip to Mystic Falls. Of course, we thought this was a normal town. Turns out, it's filled with vampires and werewolves. They call us, the New Breed. They thought there was only the werewolves that turned into actual wolves ONLY on a full moon were the only kind. But we turn whenever we want, and not just on a full moon. I didn't even know my bite was lethal to vampires till now, heck I didn't even know vampires existed. But hey, we learn something new everyday. Now Stiles has two more things to worry about. The werewolves in Mystic Falls, and the vampires.
Making friends with vampires is hard, when you're actually related to Elena Gilbert. Hey cousins are fun right? Until you get the enemies she has, which just sounds as fun as being cousins with a vampire! Stefan and Damon were easy to befriend because they wanted us on their side, and not whoever this Klaus is. Apparently he's an original vampire who's immortal, or you know SOMEONE WHO CANT DIE! Also his siblings are immortal, and if you kill them with this "White Oak Stake" thing then you have to be careful, because once they die, the people they've turned, and the people that were turned, turned people will die. It makes absolute no sense, but let's just go with that.
HEY, I mean if Stiles wants to, he can turn into a supernatural creature and be able to heal people and stuff. You know, becoming a vampire and stuff. Yeah, we can already do that ish. We as in, Scott and I, are "true alphas" we're not really sure how that happened because "True Alphas" are really rare, and a pack is only supposed to have one alpha, but I guess ours is an exception. Though our best guess is that our genes were so alike I guess. We're honestly not sure. But anyways, I don't think Stiles wants to live forever, end up being alone once me and Scott die. Yeah, no thanks.
