The conflict over Fran's bedroom is moot. There are two empty bedrooms, one of which was occupied by Vint's daughter Sonya. Why he and Naomi didn't move into Sonya's room when she moved out is not explained.
Beginning with this episode the main cast was credited in the opening credits in every episode, whether they actually appeared in the episode or not. In the original NBC run, the main cast members were credited only for episodes in which they appeared.
With Fran's demise in a tavern's toilet, she becomes Mama's second relative to bite the bullet in a bathroom; the first was her husband Carl, who passed away in the privy at home.
This episode establishes that Ed and Eunice have moved to Florida. Two years passed between the airing of the last NBC episode in 1984 and the airing of the first syndicated episode in 1986. During this time series producer Joe Hamilton and Carol Burnett entered into an acrimonious divorced. According to Vicki Lawrence's autobiography this led Burnett to become somewhat angry with her when she (Burnett) found out that Lawrence had signed to continue Mama's Family in syndication for Hamilton. Burnett had wanted to start a completely new series on her own featuring the Mama and Eunice characters. This led to Burnett cooling her relationship with Lawrence as well as the rest of the cast. With the passing of Hamilton in 1991 Burnett made peace with Lawrence and the two rekindled a close friendship. Thus, this explains why Burnett, and likewise Harvey Korman, never returned for any guest appearances as Eunice and Ed on the syndicated version.
It's often been erroneously cited that Rue McClanahan was dropped from the series once it went into syndication in 1986. In reality, however, McClanahan had signed to play Blanche Devereaux on The Golden Girls in 1985 preventing her, along with Betty White who signed to play Rose Nylund, from continuing with the series. Thus, McClanahan's Aunt Fran was killed off while White's Ellen, save for one guest appearance in season three, became an off screen character.
