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).
