Lore & Background
Debra was born to Doris and Harry Morgan on December 7, 1979. She is the sister to Dexter Morgan, whom Harry legally adopted after rescuing him from the scene of his mother's murder when he was three years old, several years before Debra was born. A tough, foul-mouthed tomboy, she craved her father's attention and envied Dexter for the amount of time Harry spent with him, unaware that Harry was training him to be a vigilante serial killer. When Debra was a teenager, her mother died of cancer.
From then on, she decided to become a homicide detective, like her father, and took Harry's gun to practice shooting. Dexter found out and told Harry, who punished her. Hurt, Debra told Dexter that she wished that Harry had never brought him home. She was immediately remorseful for saying it, however, and apologized.
Debra was devastated when Harry died of an apparently accidental overdose of heart medication – unaware that he in fact committed suicide, unable to live with having trained Dexter to get away with murder. Soon afterward, she joined the Miami-Metro Police Department, where he had worked. She spent three years in patrol and then another two years in vice before being promoted by Captain Tom Matthews (a friend of her father), becoming a Homicide officer at the start of the first season.
Reader's Guide
Debra Morgan is characterized as smart and capable, yet unsure of herself, and so she relies upon Dexter's seemingly limitless expertise on murderers to solve difficult cases. Initially assigned to Vice, she is desperate to be transferred to Homicide. After Matthews promotes her, she starts to grow self-confident, relying less on Dexter's abilities and more on her own. Throughout the series, her relationships are often complicated by her proximity to serial killers.
She dates Gabriel in season two, whom she preemptively handcuffs during a sexual encounter out of fear he might try to kill her. She later dates Anton Briggs, a confidential informant she saves during the Skinner case. Her relationship with Quinn becomes intimate after Rita's murder. Debra's career milestones include being selected for Lundy's task force investigating the Bay Harbor Butcher, solving the Skinner case to earn her detective shield, and deducing that Christine Hill was Lundy's killer.
Her personal trauma is a recurring theme: she is kidnapped by the Ice Truck Killer, shot alongside Lundy, and struggles with the aftermath of these events. By the end of season two, she has regained her confidence and is more determined than ever to improve her career and get a detective shield.
