Let’s just be honest that other women had no purpose in the movie. All she did was come and expose what the mother has done. The mother raised that girl and made sure she had everything she needed and kept her safe. She was better off not even leaving in the first place the mother was making the world pure with good people who have high levels of intelligence and nothing but good intentions. I really liked the movie but didn’t understand the ending so well. Like is the mother still alive ??? Or what ? I would have much rather the mother to stay in the picture considered the amount of love and care she was showing for the new baby brother.
