I have to disagree with you, in my view, and as you said it can be views. Maytag has stated that she was not interested in sex with Moss, she's in a dangerous situation. She's being held against her will, by people she has nothing to do with. Her lover is missing and she has no idea about her safety. This is more than just about a broken promise. She's been forced into making a decision against her will. If not for her own safety, maybe for Bern's. I would call what Moss is doing rape.
If a mother is being held against her will, and her child is being held somewhere else, and someone told her she'll be released if she has sex with them, I would NOT call that consensual, that would be rape. Again, this is my view, you can hold a different one and not call it rape, if you don't, then we'll just have to agree that we disagree.
