When the werewolves learn of Bella's ''death'', they attack the Cullens' house in an attempt to kill the baby as they fear it would become a threat. Edward, Alice, and Jasper, defend their home with the help of Leah and Seth, and are later assisted by Carlisle, Esme, and Emmett. Jacob then runs outside to stop the fight and phases into his wolf form. Jacob and Sam shortly communicate with each other telepathically. Edward reads Jacob's mind, announcing that Jacob has imprinted on Renesmee, and since it's the wolves' most absolute law not to harm anyone who has been imprinted on, they are forced to leave. After Bella is cleaned and dressed, Edward's venom heals her body, and two days later, Bella's body starts to regain and begins to resurrect, during her transformation, she begins to see memories while still dead. Her bite marks disappear, makeup is formed on her face, her cheek line shades fade, regular weight and chest size and normal skin. As the screen turns to Bella's closed eyes, they then consciously open up with blood-colored red eyes, appearing to be that she is now be a vampire.
