The fifth season of Dexter premiered on September 26, 2010, and consisted of 12 episodes. The season focuses on how Dexter comes to terms with the aftermath of the Season 4 finale, stopping a group of serial rapists and avoiding a corrupt cop who learns his deadly secret.
As the police arrive at Dexter's house, he is obviously in shock and, either because he feels guilty that his relationship with the Trinity Killer, Arthur Mitchell, caused Rita's death or because he is answering a question ("Sir, did you say that you called this in?") asked by one of the police officers, admits "it was me". Quinn is already suspicious about the circumstances surrounding Rita's death, considering it did not follow Trinity's modus operandi. He is also suspicious of Dexter's unemotional manner after the incident. Astor takes Rita's death particularly hard, and blames Dexter for it. Unable to reconcile, Astor decides that she wants to live with her grandparents in Orlando, Florida, and she and Cody leave Miami.
Miami Metro begins investigating a severed head left in a Venezuelan neighborhood, and also find several related cases. The suspect is quickly nicknamed the Santa Muerte Killer. The FBI, unable to find Arthur Mitchell, follows its only other lead, Kyle Butler (Dexter's alias when interacting with the Mitchell family). Quinn recognizes the similarities between sketches of Kyle Butler and Dexter. Dexter finds a Department of Sanitation worker, Boyd Fowler, who is responsible for the deaths of several women. Dexter hires a nanny named Sonya to care for Harrison. Dexter eventually kills Fowler, but the crime is witnessed by Fowler's next victim Lumen Pierce (played by Julia Stiles), whom he has in captivity.
Dexter tries to care for Lumen, but she is understandably suspicious of his motives, asking Dexter if he is going to "sell her". Quinn tracks down the Mitchells, who are now in witness protection. He approaches Jonah Mitchell at a small convenience store and shows him a picture of Dexter, asking if it is Kyle Butler, but an undercover FBI agent interrupts before Jonah can answer. Quinn is suspended without pay by LaGuerta for disobeying her orders. She continues to defend Dexter. Quinn seeks the help of a disgraced fellow officer to investigate Dexter. With Dexter's help, Deb closes in on the Santa Muerte killer. Debra lets him escape during a hostage standoff in order to save the hostage's life.
