Summer Together, Fall Apart

S5 E1: After spending summer vacation together, Charles and the Powell family return home, and the children complain that Charles' rule-making ruined their trip. Charles gets permission from Mrs. Powell to let the kids make their own rules. Walter feels he is not needed anymore and informs them he will be staying with Ellen for a few days. Each one of the children is allowed to make one rule for himself or herself, and unanimously they decide to have no rules. Charles, tired of being the villain, lets them do as they please, hoping they will learn a lesson.
