Nathan gets frustrated after he's forced to drive Carol around town on her weekend errands yet again and demands that she learn to drive or find another chauffeur. Debbie volunteers Adam to drive Carol around, which neither are thrilled about initially, but the two wind up bonding and having a grand time in the car together. Carol starts baking Adam cookies, doing his laundry, and generally treating him like her favorite son to make Nathan jealous, but the motherly affection ultimately scares Adam off. Carol and Nathan get into an argument about their relationship dynamic, and Carol decides to prove to Nathan that she can learn to drive, taking Tom up on his offer to teach her. Both eventually come to the realization that they overreacted and they make-up... seconds after Carol accidentally hits Nathan with her car.
