why did rita die in dexter season 4
Rita Bennett In the fourth season opener, Rita and Dexter are living happily together in a suburban neighborhood with Astor, Cody, and new baby Harrison. In "Remains to be Seen" Dexter is in a terrible car accident, and Rita demands that he give her his keys so that she can drive him. In "If I Had a Hammer," friction begins to develop in the couple's relationship, and Dexter seeks guidance from Arthur Mitchell (John Lithgow), a family man who appears to balance his responsibilities with his secret life as the "Trinity Killer". In "Hungry Man," Rita works hard to prepare Thanksgiving dinner. She shares a kiss with the next door neighbor, Elliot Larson (Rick Peters), when she asks if she can use his stove. Dexter arrives for an appointment with Rita for marriage counseling, but gets called to a crime scene as soon as he arrives. Soon after, Rita confesses that she and Elliot kissed, although Dexter tries to brush it off. Rita later admits that she felt hurt that he did not seem to care about her indiscretion. Dexter then punches Elliot and warns him to stay away from Rita, which reassures her that Dexter loves her.[40] In the fourth season finale, Dexter asks her to go out of town so they can have a belated honeymoon; in reality, Dexter wants to keep her safe from Mitchell, who has learned his real identity and threatened to kill him and his family. After killing Mitchell, Dexter returns home and finds a message from Rita that she returned to pick up her identification for the flight. Dexter finds her dead in the bathtub â€” Mitchell's last victim.[41][42] In the fifth season premiere "My Bad", Dexter realizes, much to his own surprise, that he genuinely loved Rita and is devastated by her death. Julie Benz reprised her role as Rita as a special guest star in a flashback to her and Dexter's first date,[43] and as a corpse.[44]
