Clinton Avenue Memoirs - S5-E16
Continuity mistake: The front door of Sophia's former apartment is on the right wall, under the stairs. The fireplace is on the far back wall to the left, next to the foot of the stairs. But in the earlier episode, "A Piece of Cake", the front door is next to the stairs, there is no fireplace, and Sophia's bedroom door is where the front door is in "Clinton Avenue Memoirs".
Chosen answer: Rose's husband Charlie died making love to her. There are at least 3 different ways Blanche's husband George is said to have died: 1. Blanche was getting a pedicure when he was killed. 2. He had a car accident and died. 3. He had been in a coma and died. In theory they could all be combined (he had a car accident, fell into a coma, then died while she was having a pedicure), but that's conjecture. I'm not sure how Sophia's husband Sal died.
The episode where Blanche said her husband was in a car accident, she said she was on the phone with an officer (who was eating potato chips, crunch) who was at the scene of the accident, and the officer said George was hit head on and died.
