In this hilarious episode, Frasier is surprised by a blast from his past: Diane, a barmaid at the bar he frequented in his previous days in Boston, Cheers. Furthermore, Diane was also his fiance who left him at the altar many years ago, an incident from which Frasier's heartwounds have never healed. At first Frasier struggles to impress his former lover during a quiet dinner in his home, (accompanied by Martin, Niles, and Daphne) by proudly displaying his awards of accievement and breaking out his most rare and exciting bottle of wine. However, Diane appears to be unimpressed by these displays, for example claiming that she herself has the bottle of wine that Frasier deems his most important on hand at all times. This shell of nonchalance breaks down in time when Diane discusses a new play she has written which is being put on at a local theater and is the reason she is in Seattle. She is upset because her life has fallen apart, as her husband has left her and the backer for her play pulled out at the last minute. Frasier agrees to help her with the financial troubles of her play, and interprets their relationship as one which is soon to restart. Niles warns him about this, and stresses how important it is for him to tell Diane how deeply her past actions have effected him. When it comes time for Frasier to view the play during a special dress rehersal of the play, he is shocked by what he sees. The curtain rases to reveal a set which is shockingly reminiscent of the previously mentioned Cheers from days past. Furthermore, all of the characters have two things in common: they are all characatures of other regulars from the bar, and all of them (at least the male ones) are obsessed with the character modeled after Diane. It is at this point when two important events take place. First, Frasier realizes that Diane is currently romantic with one of the actors. Second, he gets the chance to tell Diane how he feels about their past when he instructs the character modeled after him in how he should feel about the Diane character's leaving him at the altar. Frasier explodes in an emotional torrent and walks out on the rehersal. However, in a scene which is implied to take place muhc later in the day, Frasier meets with Diane once again to say goodbye forever.

This episode had a lack of adorable Eddie moments, aside from the ending where Martin scolds him from chewing on his socks. Furthermore, there was also a very disapointing lack of Roz time.
