That play at the end there is ballsy as fuck.
Also for all the people defending the mother, of course it's natural to be protective of your children, but she's clearly shown to have taken it to concerning extremes. This is the kind of parent for whom, even though they repeatedly use it, the word "adult" has no real meaning, because to a person like this, they will never see their "perfect cute child" as an adult regardless, and will try to maintain their control on their life forever unless someone (preferably their own child themself) stops them.
