Becky stuns Roseanne by asking for birth-control pills. Dan and Roseanne open their new motorcycle repair shop business, Lanford Custom Cycle, while Roseanne continues working at Rodbell's luncheonette. Darlene meets David Healy (Johnny Galecki), Mark's younger brother (in his first appearance, the character was named Kevin). After a brief stint working at Rodbell's perfume counter, Jackie enrolls in truck driver school. Nancy (Sandra Bernhard) is introduced as Arnie's fiancée. After a night of heavy drinking, Jackie wakes up in her bed with the newly engaged Arnie. Darlene's personality shifts into a sullen goth teen. Jackie's former boyfriend, Booker, makes a surprise appearance at a Halloween party. Roseanne's neighbors, Kathy and Jerry Bowman, move back to Chicago. Roseanne gets breast reduction surgery. Crystal gives birth to Dan's new half-brother, "Little Ed". Roseanne and Dan accompany Arnie and Nancy to their wedding in Las Vegas. At the end of the season, Lanford Custom Cycle fails, and Rodbell's Luncheonette closes. Nancy is single again after Arnie leaves her and claims he was "abducted by aliens".
