Claire's and Jeannie's mother -- the only woman on earth more critical than Claire -- visits the Wennick household for Christmas, and makes no secret of the fact that Claire is her least favorite relative. Although Tucker at first enjoys seeing his aunt put in her place, he starts to feel bad for her, and eventually tells his grandmother what he thinks of her motherly advice -- which doesn't quite have the desired effect. Meanwhile, Leon schemes to find out what Jimmy does in his private greenhouse, and Grandma Wennick's rottweiler, Vegas, ruins Christmas dinner.
