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 Hartman
In late 2013/early 2014, the writers introduced the Carter family and Dexter immediately clashes with the daughter, Nancy Carter (Maddy Hill). Best admitted that of all the female characters, Nancy is one of three that he thought Dexter would work well with, due to the "nature of the characters." Despite Nancy's parents, Mick (Danny Dyer) and Linda (Kellie Bright) seeming very protective of their children, Best believed Dexter's charm would help him win them over. However, he hinted that Mick would be much tougher than Linda. Of a potential relationship with Nancy, Best said, "Only time will tell." However, Best and his costar Maddy Hill attended acting school together, and he helped her get acclimated to her new job. In an interview with "Unreality Primetime", Best said Dexter and Nancy had become "good friends." He continued, "Dexter doesn't like 'ordinary' and [Nancy]'s very much out of the ordinary." According to Best, they share a mutual attraction.
