Miles to Go - S6-E15
Continuity mistake: In this episode Rose's boyfriend Miles is revealed to be in the witness protection program and has not had any contact with people from his past including family. However, in season 5, episode 15 his daughter visited and didn't approve of Rose.
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.
