Just when things are going real smoothly for Charles, his mother, Lillian, comes to town for a brief visit. That's good, and it's not so good. Every son loves to see his mother, and Charles is no exception, except Charles' mom won't let him grow up. He's a dutiful son and appreciates her loving intervention, especially when she offers to baby-sit the Powell kids so he can go to a party. But the sparks fly when Charles gets home and Walter is beside himself because he saw his three grandchildren coming out of a violence—ridden film he had strictly forbidden them to see. Charles knows it's his mom who's guilty, but since she was standing in for him, he takes the blame. Needless to say, there are some hard feelings between Charles and his mom, Lillian, Lillian and Walter, and Walter and Charles, but in the end everything gets worked out, and Charles is back in charge.
