When Derek was 22 and he had just left the army and began teacher training and he was living in a flat in Deptford with Pip his 20 year old partner at the time. One day they had a break-in, Pip called the police as he thought they would help. When the police arrived they took statements then arrest Derek for gross indecency, as the homosexual age of consent was 21 at that time. Derek was sentenced to nine months and by the time he got out, Pip had married and would not acknowledge Derek when passing on the street.
Derek was introduced as a old school friend of Pauline Fowler. Since reuniting with Pauline, Derek started working at the Walford Community Centre and moved in with the Fowler family as their lodger. There he became a father figure to Martin and taught him to drive. Pauline started to develop feelings for Derek and when she made a move at Derek he declined revealing to Pauline he is gay but this did not fracture there friendship and he stayed in Walford.
