Once he captures her he explains that her father is responsible for altering his genes??? and now he has abilities. She also has abilities which he proves to her when she must stop her self from going into a propeller…the man has been searching for her father. She is able to track him down by his wife’s favorite flower. When they find him he is dying of cancer…there may be more but I may also have confused it for a different ending. Please help!!!!
