Additionally in the movie the relationship between Aiden and Vivian has a drastically different outcome. Instead Aiden discovers the existence of werewolves from Rafe, not Vivian and he does not reject her for what she is. After rescuing Aiden from being hunted by the pack they take off to hide, heal Vivian from the silver poison and escape the city as well as the pack and start a life together elsewhere. In the end of the film Aiden and Vivian end up together after killing Gabriel together and flee the city - the future of the pair and whether Vivian takes place as alpha is hinted at but uncertain.
