Dowell, Ben (15 January 2016). "EastEnders repeat - wherever will it be shown when BBC3 goes off air? New channel W changing Watch". Season 4, Serena and Ben. Season 4, Serena and Colin. In the 10th episode of Season 2, Norman has a flashback that confirms he did indeed slept with and then murdered her. Played for laughs (male student/woman instructor) in an episode of Blossom.
