Really? I didn't realize that. Even when this is a مقبول سوال for troll in yahoo answer, and a lot of people make a joke about it ALREADY. So tottaly didn't realize such GLARING evidence like that. It's must be conspiracy~
Yeah, Black is in both, like everyone else, I've noticed.
There's is also the surname 'Clearwater' which is used in both books. Leah and Seth Clearwater from Twilight, and Penelope Clearwater from Harry Potter. She isn't that known, cause she's only mentioned in the films a couple of times. - She was Percy's girlfriend from the سیکنڈ book.
Well, I don't think Stephanie Meyer was trying to copy Harry Potter. Thats like saying: "Look!! In this book there was a character named Lila and also in this book, but this book was out first!!" There just aren't that many names that sound right when آپ are an مصنف and Jacob BLACK sounded good to Stephanie Meyer. Its not that big of a deal.
