Seems like Deidre Hall is playing Hattie (in the pantsuit) with a body double playing Marlena (in the robe) in that particular shot. My guess is John and Marlena are having a romantic evening, and Hattie slips in to have Marlena drugged and kidnapped, so she can take her place.The first one is odd. I'm not sure if Marlena and Hattie together or not.
