Not Begbie. He wasn't on heroin, just tried to sell it. He was more psychotic than addicted to anything, and unlike most others in the movie he never really progressed past that. Guessing he is the main driving force in the second one since your scenario is probably fairly accurate.I'm very skeptical. Has there ever been a good sequel made 20 years after the original that wasn't part of a franchise? Those guys either died of heroin or kicked it and became boring ass suburb dwellers like the rest of us. I don't see how that group of characters is interesting 20 years later.
