When the fifth season returns, the story will follow the murder of Rita. "Dexter will react to Rita's death," "We will see his pain," "Grief is something he has never experienced, and we will find that very interesting." In addition, the crew said that Rita (Julie Benz) will not return to the show, but her two children will stay. "The problem of Dexter and the two children is a big problem we are going to explore this season. This season will get rid of the traditional "one serial killer for a whole season" model, and there is no "big villain." The guest cast this season is very strong, including: Peter Weller, Julia Stiles, Jonny Lee Miller, Shawn Hatosy and Maria Doyle Kennedy. The producer hinted that Dexter's sister Debra may know Dexter's secret. This season will continue to reveal the relationship between Dexter and his father Harry. Cody and Astor (Rita's two children) are angry and dissatisfied with Dexter, and Debra will try her best to take care of the two children. In addition, Quinn began to doubt Dexter's true identity, and even believed that Dexter murdered his wife Rita. It will take time to prove whether Quinn will become the second Doakes (who suffered a tragic end because of his suspicion of Dexter).
