chunk: Renton is finally roused from his nightmares and hallucinations by his parents, who tell him he needs to get tested. Despite years of sharing syringes with other addicts, Renton tests negative. Low-spirited and depressed, he visits Tommy, who has succumbed to addiction and is now severely ill and HIV-positive. Renton moves to London and takes a job as a property letting agent. He begins to enjoy his new life of sobriety and saves up money on the side while corresponding with Diane. However, Begbie, who has committed an armed robbery, and Sick Boy, now a pimp and drug dealer, move into Renton's bedsit unannounced, to Renton's annoyance.
