One Flew Out of the Cuckoo's Nest (2) - S7-E26
Continuity mistake: When Sophia goes around taking pictures of Dorothy and Lukas kissing, she accidentally takes a picture of Rose and Blanche hugging. When she takes the picture, they are still hugging and see her afterwards. When the picture develops, they are both staring at the camera with shocked looks, but the picture was already out when they turned around.
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.
