List of Dexter characters
On a visit to his sister, Dexter and Debra both feel as if they have been drugged; just before he passes out, Dexter sees Hannah standing over him. When he later regains consciousness, Dexter begins investigating Hannah, and finds that she has changed her name and married Miles Foster (Julian Sands), a wealthy businessman. Dexter goes to see Hannah, who says that she had wanted him to kill Foster, but changed her mind after realizing she is still in love with Dexter. Foster warns him to stay away from Hannah, and has him beaten up. Dexter goes to Foster's boat to protect Hannah, but finds that she has already killed him. The two of them dispose of the body, and promise to watch out for each other. The two end up having sex and rekindle their relationship.
Dexter (TV series)
Orphaned at age three, when his mother was brutally murdered by a man with a chainsaw, and harboring a traumatic secret, Dexter (Michael C. Hall) was adopted by Miami policeman Harry Morgan (James Remar), who recognized the boy's homicidal, sociopathic tendencies and taught him to channel his gruesome passion for killing in a "constructive" way—by killing only heinous criminals (such as child molesters, mob assassins, rapists, serial killers of the innocent, etc.) who had slipped through the justice system. To satisfy his interest in blood and to facilitate his own crimes, Dexter works as a forensic technician specializing in blood spatter pattern analysis, for the Miami Metro Police Department (based on the real-life Miami-Dade Police Department). Although his drive to kill is unflinching, he is able to simulate, and in some cases feel, normal emotions and maintain his appearance as a socially responsible human being. Dexter is extremely cautious in his kills – e.g., he wears gloves and uses plastic-wrapped kill rooms, carefully cleans up afterward, segments the bodies and disposes of them in the ocean – to reduce the chances of detection.
