The Driver's Seat

S6, E11: Leon manipulates Nancy and Jackie into voting to serve breakfast at the diner, among other changes, without consulting Roseanne. Starved for attention, D.J. steals and wrecks the family car while joy-riding, causing a stressed-out Roseanne to lash out in a violent way that she quickly regrets. The power-play between Leon and Roseanne escalates, prompting Dan to have a talk with Leon about backing off. When Dan realizes that Roseanne is not just being paranoid where Leon is concerned, he steps aside, leaving Leon to Roseanne's mercy.
