After breaking up with Claire, Frasier pursuits Lana - but that falls through when her ex-husband comes back into the picture. After sour words with his father, Frasier takes off for the cabin to find solitude for his thoughts. Solitude is something that he definitely does not find however, as Frasier's mother, first ex-wife Nanette, ex-girlfriend Diane, and ex-wife Lilith come with him on his vacation as figments of his subconscious.
Both parts of "Don Juan In Hell" are even smarter than most Frasier episodes and yet are also classic Frasier. Bebe Neuwirth, Shelley Long, and Rita Wilson all make hilarious guest star appearances in this episode and are its highlight. Frasier has to battle the four most important female relationships in his life as he tries to figure out why he always loses in love. Of course, none of these four women are the least bit normal and that makes "Don Juan In Hell" absolutely hilarious and one of the best episodes of Frasier.
