Marlene and Mike, to name but a few. His enemy is DCI Roy Slater. Del is courageous and, although not intellectual, he is quick-witted but inadvertently gets Rodney into trouble. In "Wanted", when a mentally unstable woman accuses Rodney of attacking her, Del makes a joke of it and says that the police have named Rodney "The Peckham Pouncer". Del is afraid of doctors and dentists. His favourite song is "Old Shep", and his favourite band is The Who. He likes the superhero Batman. In "The Long Legs of the Law" he implies that he supports Chelsea. In "A Slow Bus to Chingford" Rodney tells his date Janice that Del "used to be cultural advisor to the Chelsea Shed", a reference to the Shed End at Stamford Bridge where the most fanatical Chelsea fans would stand. In other episodes, a Crystal Palace F.C. scarf is seen hanging from the hallway. He cannot swim – the certificate in his possession is not his – nor fly a hang glider. He is selfish, but can be very thoughtful, such as when he tried to help Rodney get over his wife Cassandra's miscarriage of their first baby. He never hesitates to remind people about how he brought Rodney up practically on his own after their mother died and father left, often using this fact to win arguments with Rodney. He is also shown to be quite duplicitous, once described by corrupt policeman and former school peer Roy Slater as "A man who could talk himself out of a room with no doors". In "May the Force Be With You", he was arrested by Slater for handling a stolen microwave, but gained his release by agreeing to name the thief provided he and his family were granted immunity from prosecution. Once Del's immunity was guaranteed, he confessed that he was the thief, confidently showing a shocked Slater his immunity papers. Del and Rodney often tease Uncle Albert about his appearance and resemblance to Captain Birdseye, although they show fonder feelings for him when he dies in "If They Could See Us Now". Rodney apologises for the way he treats Albert in "Sickness and Wealth". In Rock & Chips, Del Boy is shown to have a deeply close relationship with his mother Joan, whom he is very protective of. (He is Joan's favourite, to the point that she refuses to run away with Freddie Robdal
