It's Christmas Eve and the Pembroke household is buzzing with activity. Grandma Irene, Stan's mother, is expected for her yearly three week stay with her grandchildren. Jill is cleaning an already immaculate house and wonders why her mother-in-law's visit still upsets her in the same manner it did fifteen years ago. Charles is trying to console Jason who is depressed and sad to see him go. Charles plans to go home for the holidays; he will spend his vacation with his parents in Vermont. The phone rings, and his dad informs him that they are completely snowed in. This news makes Jason suddenly feel much better, but Grandma Irene becomes more and more jealous of Charles. She has a long conversation with Stan, and both explain their feelings to each other. He succeeds in helping her accept that Jill has her career, Charles is an important part in the children's lives, and that by no means this arrangement should make her feel insecure towards the attention they give to him. Her grandchildren love her very much and always will.
