 In a reversal, when Mary revives, Emser has strapped her to the bumper with electric cords and Christmas lights and takes her on a sadistic, all-night "revenge drive".Along the way, after a struggle, Emser kills a gas attendant (who was about to call the cops) by pumping petrol down his throat and the attendant throws up blood after Emser departs.Emser parks back at his own house, leaving Mary trapped in his garage, as she did to him.
