Donnie Stevens was the oldest child and first son of Steve and Eileen Stevens. While not an exceptionally smart boy, Donnie was shown to excel in athletics and seems to have shades of the "big brother instinct." While most of his story lines revolve around his sports and dating, occasionally he will become involved in whatever is going on with his younger siblings. In "Scrub Day," he left to go to the school and came to Louis's aid. Also in "Battle of the Bands" he tries to keep Ren from going to a high school party.
