Sick Boy's Unifying theory of life

Sick Boy's Unifying theory of life

Sick Boy is an intelligent man who enjoys doing heroin, hanging out with his friends at pubs and clubs and watching James Bond films. He is a fan of Sean Connery and has a lot of knowledge on him as well as the many trivial facts about the 007 movie adaptations he appeared in. He is also a rather cold person and doesn't really care much for most people, however he is shown later to redeem himself in T2 although his attitude most likely doesn't change.



He is seen first when he, Renton and Spud are fleeing from the police after committing thievery. He later appears when he and Renton are discussing his theory of life in the park before shooting a dog in the posterior causing it to attack it's master much to their amusement. He later appears in the pub when Begbie is telling everyone the story about a game of pool he had with Tommy (in which the truth was twisted to make Begbie seem like he actually won the game), after Begbie throws his pint over the balcony causing it to hit a girl in the head, Begbie ends up causing a massive pub brawl after kicking a man in the testicles, with the others including Sick Boy watching from above. He later appeared in a few other scenes and after seeing his own child starved to death Sick Boy was devastated and filled with grief.

Soon later he appeared after Spud was arrested and everyone was at the pub with Renton who was going to get his act together and stop taking heroin. He later appears when Renton has became a real estate agent where he is now a pimp and a drug dealer, he and Begbie then move into Renton's flat much to his annoyance. Later Sick Boy attends Tommy's funeral after the latter died from HIV complications. After the funeral Sick Boy and Begbie tell Renton and Spud their drug dealing plan and Renton (after being convinced by Spud) reluctantly agrees to help. After succeeding in their scheme they go to a pub to celebrate however the celebration is cut short after Begbie causes yet another fight after a man accidentally bumped into him making him spill his drink all over his suit, Spud attempts to intervene only for his hand to get sliced open by Begbie's knife, Sick Boy suggests they leave before the police arrive which they do after Renton gives Begbie a cigarette. The next day Renton steals the drug money and leaves leading to Begbie having a mental breakdown by destroying everything in the hotel room in a fit of rage. Once the police arrive Spud and Sick Boy flee the scene quickly.


After Renton's return to Edinburgh Sick Boy is still angry at him for his betrayal and fights him inside of his aunt's pub. He later behind Renton's back talks with Begbie (who broke out of prison) about revenge. He later does redeem himself during the film's climax after realising the error of his ways and saves Renton from certain death after Begbie hung him with elevator cables. Begbie is about to attack the two before Spud knocks him unconscious with a toilet bowl. The three then lock Begbie in the boot of the car and park it outside of HMP Edinburgh for the police to discover. In his final scene he and Renton are discussing Spud's idea of writing the stories of their experiences into books and their concern over how they probably won't do well.
