Dean Stanley is a footballer who attended a party hosted by Liam and Nathan McAllister in October 2010. When Dean arrived at the party, Liam and Nathan were annoyed and decided that they needed to get rid of him. Mitzeee Minniver was shocked when she spotted Dean, knowing that he and his friends gang-raped a girl in a London hotel and then terrified the girl into retracting her statement.
Dean flirted with Nancy Hayton and Nancy instantly fell for him. Dean invited Nancy upstairs where they kissed passionately on the bed, but Dean invited three other men in the room to have sex with Nancy. After Chanterelle told Mitzeee about Dean taking Nancy upstairs, Mitzeee panicked and told Chanterelle that they had to stop him. Mitzeee and Chanterelle burst into the room with Nancy and Dean, with the latter inviting them to join in. Mitzeee informed Dean that Nancy was a journalist, which resulted in Dean turning on Nancy and leaving.
Mitzeee later informed Liam of Dean's behaviour, to which Liam told him to leave. When Dean refused, Liam nearly became violent, but Carl Costello arrived in search of his sons Riley and Seth Costello. After Nathan's girlfriend Sami distracted Carl, Liam and Nathan threw Dean out of the mansion.
