Nurse Andy O'Brien moves to Albert Square in March 1985 along with his girlfriend Debbie Wilkins (Shirley Cheriton). Andy and Debbie are decidedly 'middle class', in contrast to the working class locals who inhabit the Square. Andy and Debbie have a rocky relationship. Andy wants to settle down and start a family but Debbie is not so keen and she soon attracts the attention of policeman Roy Quick (Douglas Fielding). Debbie obviously enjoys being pursued by Roy so they agree to have an open relationship. The pair continue to live together, which is not ideal for Andy, as he still has feelings for Debbie and regularly gets jealous when he sees her with other men.
