In 1987 he met his son Nick for the first time when both coincidentally turned up to visit Dot. Charlie and Nick hated each other and both tried to get rid of each other so they could get the opportunity to con Dot. Charlie discovered Nick had cheated some of his friends out of money and had been involved in some house burglaries, and that is why he was hiding at Dot's house.
He used this to try and get rid of him by teaming with Graham Clark who was an old friend of Nick and wanted to get back at him for going to prison for Nick's crime. Graham forced Nick to leave Walford and before Nick left he revealed to Dot that Charlie grassed him to the people who were looking for him. Dot got angry and told Charlie to leave too.
In 1989 it was revealed Charlie had a bigamous marriage to a woman called Joan Leggett, who turned up in Walford looking for him and met Dot instead. Eventually Charlie also turned up and found his 'double life' had been exposed. It was revealed he had told Joan his name was Tommy.
In 1990 when he turned up to con Dot out of her bingo money he found that his son Nick was already plotting to steal her winnings by poisoning her, but Nick soon backed out with the persuasion of Charlie. Unfortunately just when Charlie was trying to tell Dot that Nick was going to poison her and he stopped him, Dot told him to leave once again not believing that Nick would do such a thing.
In July 1991 Dot received news that Charlie had died in a lorry accident but his death was not shown on-screen.
