Continuity mistake: Fran's belt changes when she is in the kitchen from a pink leather one to a zebra one and then back to the original.
Suggested correction: As soon as it cuts from the show's intro to the first shot in the kitchen, we see Fran buckling her old zebra-striped belt around her waist. When Niles picks up the artificial lemon tree we see Fran touching her belt, and as the camera faces Niles when he exits the kitchen Fran unbuckles her belt offscreen. In the next shot Fran's zebra-striped belt is in her hand, and she places it back in the box of her old stuff from her Ma's house. No continuity issue. Starting time code 00:03:35.
The Pre-nup - S5-E20
Continuity mistake: In the scene where Val and Fran are in the kitchen, Fran jiggles her tea bag, the removes it and places it on the napkin beside her. Brighton enters and after a brief conversation Fran returns to the table carrying cream and sugar. She then jiggles and removes the teabag from her cup again. (00:07:00)
Suggested correction: Fran is in the kitchen with her mother, not Val.
