...That's one possibility... but the other one might be for the mom to feel relieved and grateful for having such a daughter (..to some stand point). and personally I hope its the later ( though guilt will be there for better or worse). Even Kyoko said she wouldn't want to be a mother, ... that she does not feel she would be able to love 'that' child.
isn't that like her mother, so I think Kyoko will at the very least understand some of her mom's feeling now that the cloud cover is weaning.
I also think kyoko has a more positive view and her mom has a negative view, though to be fair kyoko has a black and white sight, you are either her friend or an enemy (even if you are thankful to them...) and its reeeaally hard to get on her enemy list, but when there... be prepeared to welcome hell ... unless you can dig yourself out of it ... like Ren (became friends after learning about each other more
I think she was totally sincere and came from an honest place. I just hope the mom feels like a dick now that she knows how mature and reliable her daughter really is despite her horrible treatment of her.
"I'm most greatful to you. Thanks for giving birth to me." Way to be the bigger person, Kyoko and guilting your mother in the process. I hope she feels like the hugest asshole now.
