Debra Morgan
In "Dexter's Final Cut", Deborah disowns Dexter after he cheats on Rita and unintentionally allows pedophile Robert Chase to kill Rita and kidnap Astor. In "Dexter is Dead", Deborah takes custody of Cody, Astor and Dexter's daughter Lily Ann after Dexter is imprisoned for Rita's murder; she knows that Dexter is innocent of that particular crime, but believes that he belongs in prison. After Dexter is freed thanks to his brother Brian's machinations, she refuses to let him see the children and communicates with him only to get him to sign the paperwork to finalize the adoption. However, she is forced to rely on him when Cody, Astor and Nicholas are kidnapped by a Mexican drug lord who is out to get Brian. The three of them team up to infiltrate the drug lord's yacht and rescue the children, and Deborah and Dexter repair their relationship. Deborah saves Dexter's life by killing the drug lord just as he has her wounded brother at his mercy. Moments later, however, Dexter is killed when the yacht explodes; in his final moments, he sees Deborah trying to save him.
