On this Sunday's special episode of Desperate Housewives, Brenda Strong will actually appear on screen as the late Mary Alice Young.

How is this possible? Because "Epiphany" flashes back to the past on Wisteria Lane, showing viewers just how the Fairview Strangler interacted with Gaby, Bree, Susan and Lynette.

It should be a cool, possibly even disturbing look into how this individual grew into the killer he was revealed to be at the conclusion of last week's episode. Enjoy the four sneak peeks below at "Epiphany."
