Later seasons expanded the show's scope by exploring the family's interactions with their extended family, friends and colleagues in more depth, including Lois' tyrannical mother (Cloris Leachman); Craig Feldspar (David Anthony Higgins), Lois' hapless coworker at the Lucky Aide drugstore; Malcolm's best friend Stevie Kenarban (Craig Lamar Traylor) (who is both a wheelchair user and highly asthmatic), and Stevie's dad Abe (Gary Anthony Williams); as well as a series of continuing subplots detailing Francis' misadventures at the military academy, from which he subsequently disenrolls to work in an Alaskan logging camp, before finally landing a job on a dude ranch run by an eccentric German couple.
