Edie dies. (Season 5)
Even when you remove all the behind-the-scenesdrama, it sure looks like Marc Cherry had it out for Nicollette Sheridan. This is how he killed off Edie Britt: Her husband Dave strangled her. Then, battered and dizzy, she tried to drive away from him. Unfortunately, when she swerved to avoid another car, she hit an electric pole. As she got out of the car, she stepped into water, in which a power line had fallen and she was shocked to death. Ouch.
