EastEnders' Mark Fowler joined the BBC soap as a delinquent teenager.
However, when he returned to Albert Square in the early 1990s as a 22-year-old, he was much more grown up and a completely different person. The change had come as a result of his HIV diagnosis, which had meant he had to focus on his health.
Throughout his time in the Square, he found it difficult to cope with the illness and the restrictions it gave him, before he decided that he would leave Walford to live out his final days and enjoy the trip of a lifetime before his untimely death.
