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.
Double Dexter
Dexter eventually finds the Honda belonging to Alissa Elan, the Shadow's ex-wife. He returns at night but finds that the Shadow – Bernard Elan – has anticipated his visit, mutilated Alissa in imitation of Dexter's style, and called the police when he arrived. Dexter narrowly escapes. Bernard, a skilled computer hacker, alters relevant databases to indicate that he died two years ago. Later, Dexter's coworker Camilla Figg is found beaten to death, casting doubt on Deborah's arrest. Dexter notices differences from the cop-killings, but Hood, the detective in charge, ignores him. It emerges that Camilla had hundreds of photographs of Dexter, having had an obsessive crush on him. Hood makes Dexter the prime suspect.
