Instead of telling her friends the truth she invents a story to explain why she seems disappointed. Marshall meanwhile gets into the Christmas spirit and heads out to their house in East Meadow to decorate. After enlisting the help of a local boy, he is betrayed and stranded on the roof until Lily comes to visit.
