Continuing the last season, Sam, Diane and Frasier return to Cheers after Diane jilted Frasier at the altar in Italy, resulting in the loss of his dignity, teaching tenure, and Italian practice. Frasier now works as a bar janitor just to humiliate Diane, while Diane refuses Sam's offer to work at Cheers, looking for a job as a teaching assistant. While Sam's looking for other relationships, many people believe that he is still in love with Diane.
