Plot hole: Several days must have passed between the teaser of this episode and the rest of it, since Gabrielle has had time to make up (very professional-looking) cards and posters, gotten several dozen volunteers and reserved dresses for many of them, yet Paul has only just gotten around to disposing of Mrs. Huber's body and trying to wash the blood out of his shirt. Even if we assume the teaser takes place right after the end of the last episode (when Paul murdered her), that's still several days of keeping a rotting corpse and enough evidence to put him away for life around his house.

Other mistake: In an earlier episode where Edie and Susan are driving Martha Huber's ashes to the lake to be spread, Edie gets a flat tire and Susan changes it. In this episode, all the girls are driving with Edie's ashes and they get a flat tire. Susan asks "Does anyone know how to change a flat tire?" Did she forget how?
Carlos: You know who you are, Gaby? You're the kind of person who would have turned away Mary and Joseph from the inn.
Gabrielle: Well, they should have called ahead.
Trivia: Across Season 4: Two Lois Lanes appear together in this season: Teri Hatcher played Lois Lane in The Adventures of Lois and Clark and Dana Delaney voiced Lois Lane in Superman: The Animated Series and its follow-ups.
Question: Where did Kayla go? When did they get rid of her and where did she go? And which episode is it?
Answer: Kayla was sent away in episode 16 (The Gun Song) in season 4, after falsely accusing Lynette of child abuse. She now lives with her grandparents - probably Nora's parents.
I'm curious why we never see her again, why she never talked about, and why Tom never mentions visiting her.
