2003, as he is on day release from prison to attend his mother's funeral. It soon transpires that he was the product of a fling between his teenaged mother Paula, and her adult ex-lover Den Watts (Leslie Grantham). The discovery of his existence comes after Sharon discovers that she has a brother through her adoptive father Den Watts and another woman during the 1970s. Sharon was aware that her brother was called Dennis Rickman and that he too grew up in Walford. Charlie Slater (Derek Martin) informs her that there was a Mr. Rickman who lived locally and worked as a taxi driver, but he and his wife had both died and their daughter was living alone in their house.

After Dennis's release, Jack orders Phil to kill Dennis after he becomes independent of him. However, Dennis ends up killing Jack in a shooting next to a railway line, but not before Jack reveals that Den survived the 1989 shooting, and that the body found in the canal a year later was in fact that of another local
