Trainspotting: Renton's Betrayal Foreshadowing: Renton's betrayal was foreshadowed most obviously during the bar scene after Sick Boys's deal. When Begbie starts a bar fight and seriously injures the other man involved, Sick Boy and Spud immediately go to Begbie, while Renton remains seated. The close up shot of Renton's face, while the others crowd around Begbie ,extremely out of focus, represents his growing distance from the group.
