 CONT: After her very fumbled sexual encounter in the car parked in  the driveway, Elena, in windswept heavy rain, returns to the party  house to help her husband who has been violently sick in the  downstairs toilet. Though she carried an opened umbrella, her ankle  length coat, fully visible onscreen, should have been absolutely  soaked and there should have been other evidence of the heavy rain  elsewhere on the coat. It was evidently completely dry.
