Colin is a New York artist who meets Kelly during her internship in New York in the summer of 1995. In the Autumn, Colin moves to L.A. to continue his relationship with Kelly. He was an old acquaintance of Valerie and his livelihood was secretly sponsored by gallery owner Claudia Van Eyck in exchange for "favors".
He ended this relationship after Kelly discovered it and broke up with him. They reunited in the next episode after he promised to get a job and support himself. He also had a cocaine problem, which eventually became a habit for Kelly as well. Once Kelly hit bottom and entered rehab, Colin attempted to maintain their relationship by also dropping his addiction, but Kelly broke up with him so she could recover.
After being dumped by Kelly, Colin began a relationship with Valerie, who often served as a backer for his artwork. Colin again became entangled in dealings with his cocaine connection, Danny Five, and was arrested. He later jumped bail after Valerie posted her club assets for his bond, but was tracked down by Steve Sanders and Brandon Walsh and sent to prison to serve his sentence of at least two years in prison for drug possession and fleeing arrest. He would have been out in 1998.
