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.

Doakes resumes the hunt, however, when Debra innocently reveals that Dexter does not so much as smoke. On finding Doakes meddling in his past again, Dexter goads him into a seemingly unprovoked fight in front of the entire squad room. Doakes breaks into Dexter's apartment, and stumbles upon Dexter's blood slide collection box, and realizes Dexter's secret—that he is the Bay Harbor Butcher. Ironically, Doakes is by now the prime suspect in the case, thanks to Dexter's manipulation of the evidence.
