ok so at the fight scene in twilight whilst bella is lieng on the floor bleeding jasper stays calm yet one paper cut in new moon and he try to kill her? wat do u think to destracted by the killing of james?
I guess he was really distracted by james killing!! plus the living room in bella´s birthday must be smaller then the ballet studio and all the atention was focused at bella, including jasper´s and in the ballet studio no, the point was killing james... i don´t if you are understading me!! i guess i can´t explain better! sorry :)
Think about Edward later on...Jasper was cooped up with her alot before hand in the hotel. He was used to her scent. But he stayed away from her after. So he became less immune to her. Therefore, when she bled, he attacked.
Ha ha it has been asked by many, so many that Stephanie provided an official answer, which can be found on her website, I believe. But some things still don't add up.
