Other mistake: Notice when Dorothy gets up to talk to the doctor. She's barefoot.
Revealing mistake: Blanche, Dorothy and Rose that went on the boat with the 3 guys were stranded on what appears to be a beach. However, the "beach sand" has a lot of bouncyness to it. Giving the look of foam padding of some sort with some fabric that looks like sand. The sand doesn't actually move either while they're walking on it. (00:16:11 - 00:18:40)
Revealing mistake: Throughout the entire series every time someone is cooking on the stove there's never any steam coming from the cookware. Also looking at the burners, it's an electric oven yet the burners are never orange indicating they never really "cook" food at all.
Character mistake: Sophia tells Dorothy that lying is breaking a commandment, to which Dorothy corrects her by telling her that it's not a commandment. Actually, not lying is in fact a commandment. The biblical quote is "Thou shalt not bear false witness against thy neighbor." Whether it's an error on the part of the writers or an intentional mistake for Dorothy, it's still a mistake. (00:12:15)
Plot hole: It shouldn't matter if the neighborhood's got a petition. If the tree in question is on Mrs. Claxton's property then they wouldn't have a say in the city removing it.
Other mistake: There's a lot of talk about Pepe hurting his hands during his last boxing match. Unless there's something I'm missing, boxing gloves should provide adequate protection.
Other mistake: Rose tells a story about her mother having undergone plastic surgery to look like Raymond Massey back when she still lived in St. Olaf. However, we see her mother in an earlier episode and she looked nothing like him.
Factual error: At the end of the episode Rebecca has her baby. When the doctor cuts the cord he hands her to Rebecca all clean and spotless. Babies have a lot of blood on them when they are born.
Chosen answer: Yes, you are correct, as stated, In one episode Blanche said he had been in a coma for days, in the episode where she's in her dream, she said "The day you died ... The police told me you had been in an accident." Thus the original answers theory is wrong. If he had been in the accident the day he died he could not have been in a coma for days.
Valentine
Yeah, in another episode she relates how a thoughtless state trooper phoned her and told her that her husband was dead with his mouth full.
