Shivam's jealousy anger and frustration was because he is just as confused as Nandini is
Nandini's anger is against her mother.Which actually went down because of Anandi and also Chakor but was re kindled by Mangala in order to take her mother's place in that child's life as well as in that child's heart.
Anger is against her mother whom she doesn't know.
Mangala if she can't be the child's mother she won't let the child meet her mother.
Finally Anandi is moving forward and decided to take things into her hands and doing it her way.
Most likely the psychologist won't succeed in unearthing what lies in that child's mind.
Anandi and Akheraj interaction happening in front of the child is the most likely key to the situation.

This Mangala's agrression what happened when the child was being tortured abused starved beaten up tied up day in and day out? Why did she not show this aggression then?
What was the explanation given for her indifference to the child's sufferings? She was helpless in front of Akheraj and Harki😛
Glad that Dsa put this woman in her place by reminding her that Anandi is child's mother.
