List of Dexter characters
After the baby, Harrison, is born, Rita and Dexter move into a house together in the suburbs. Rita begins to notice a pattern of lies from Dexter, including deceiving her about the concussion he suffered in the car accident and the ownership of his old apartment. Rita and Dexter then go to a marriage counselor, who allows them to sort out their problems and instigates peace between them. However, their neighbor, Elliot, begins to fall for Rita, kissing her and pointing out that Dexter is never home. Though she initially kisses him back, she quickly ends it before something begins. In the Season 4 finale, Rita is murdered by the Trinity Killer, leaving her son Harrison sitting in a pool of her blood.Debra Morgan (known as Deborah Morgan in the book) is the younger foster sister of Dexter and biological child of Harry Morgan. Debra believed that she truly knew her father, but is unaware of the secrets he kept, especially concerning Dexter (whom she sees as a true brother). Inspired by their father's legendary police career, Debra joined the police and desperately yearned to become a homicide detective. Initially assigned to Vice, she was transferred to Homicide at the start of the first season. Being new to the job and very insecure, she largely relied on Dexter's expertise on murderers to solve difficult cases. Debra met Rudy Cooper, who unknown to her is the Ice Truck Killer using her to get close to Dexter. She falls in love with him, but is later kidnapped by him in order to be able to reveal himself to Dexter. She is bound to a table in the same manner that Dexter kills his victims, while Dexter and Brian discuss her fate. In the show, she is unconscious, but in "Darkly Dreaming Dexter", she is awake and finds out that her brother is a killer. Debra is severely affected by Rudy's betrayal; she moves in with Dexter for fear of being alone.
