ok, maybe not all
But I see it a little differently.
The relationship with Charlotte is as bad as it was at the beginning.
She feels uncomfortable around him and wants him out of the house as soon as possible.
She doesn't like the fact that Emma trusts him.
Charlotte's sister acts like a little girl and punishes him without even asking what his problems are.
Emma's big sister's behaviour needs no words.
Emma's behaviour is more like that of a nine-year-old girl than a young adult.
It goes far beyond the behaviour of a naive young woman. yes, her mother shields her from the outside world, but she seems more like a little child.
Best Regards
