A discussion on another forum is making me cranky.
Just because most of the Handmaids have not shown more outward signs of distress when being raped, doesn't make the Ceremony any less of a violent rape. And the scene wasn't gratuitous, it's there to underscore the fact the Ceremony is rape and to show why most of the Handmaids don't attempt to physically fight back (it doesn't make any difference).
Anyway this was a good but super depressing episode. The reunion with Hannah seems more cruel and ill-judged than kind to either of them and it necessitates them going through the trauma of another forced separation.
Eden sobbing away to herself broke my heart as well. Whatever Nick's feelings toward her, I found him unbearably cruel in that scene. She's a 15 year old kid who feels completely unloved and alone and like Hannah, she's been taken away from her family. She mentions her mother in most of her scenes.
