Paul....

Paul is a Quileute teenager who can turn into a werewolf. He was the third one to join the pack. He is most volatile member of the pack, he became so enraged when he learned Jacob told Bella about the pack that he turned into a werewolf and attempted to attack her. He currently seems to have no ill feelings towards Bella or Jacob. He is prone to angry outbursts, causing him to burst into his wolf form. In Book 2 of Breaking Dawn, we learn that Paul has imprinted on Jacob Black's older sister Rachel. This annoys Billy and Jacob because he is always at their house eating their food; however, Billy is happy that Rachel is sticking around longer because of Paul. By Breaking Dawn, Paul also seems to have gotten better control of his temper.
