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.
Joel Dexter
Joel was originally introduced as a "mysterious newcomer" who is hiding a secret. It was then revealed that he is the long-lost son of established character Warren Fox (Jamie Lomas). Lomas had already announced his intention to leave the series and Joel played a role in Warren's departure storyline. Still has stated that when his character first arrived on-screen, he was "quite floaty" with nowhere to live. Joel was later given further connections to characters within the show, such as Brendan Brady (Emmett J. Scanlan) who gives him a "criminal education" and Theresa McQueen (Jorgie Porter) as they begin a relationship. In May 2012, Joel was involved in a stabbing storyline. Still has spoken of his efforts to make the scenes in which Joel is stabbed as realistic as possible. This was because he felt that many people were victims of stabbing at the time. Upon the character returning to the show, his storylines were reunited with his father, trainee to become a priest, being targeted by Sienna Blake (Anna Passey) as part of her revenge for her daughter's death, being responsible for his aunt Katy Fox's (Hannah Tointon) death from a drug overdose and his relationship and later engagement to Cleo McQueen (Nadine Mulkerrin).
