so when the Showrunners fuck up the story so badly, you get things like this:
The director of that episode said that he believed that what he filmed, was consensual sex by the end. Obviously the people who watch TV or know the definition of rape disagreed because it's been nothing but "omg rape" since that episode aired. So because the Director fucked up that scene, we get theories like this.
It wasn't written as a rape scene (obviously not in the novel, but also not in the episode's script since the director wasn't aiming for rape, but was aiming for "no it's not right to do it here, under our son's corpse, but, ok i agree let's have sex" he just fucked that part up) so of course the rest of the episodes aren't going to reference or resolve the "omg rape" since their scripts were written assuming there was no rape. So for TV viewer's its like "the elephant in the room" and it won't be addressed because it was never actually intended to come across the way it did.
