Unlike popular opinion I don't think ye koi plan he
Beacuse moksh is really traumatized not acting Malhar won't do such a thing with moksh is 100% sure
If I am to guess
Malhar ne jungle mei kuch awaz ya kiska presence mehasoos karke moksh ko kahi jaale chupne bola
Then I think when he was stabbed he screamed even kallu heard that scream na and came in that direction
So I feel moksh also hear his father's sound and came to check on Malhar
All he saw was Anupriya taking out the knife and hence believe that Anu did it and showed her
I understand kid can't talk but if he has seen then real murderer he would have reacted when Anu was arrested using some expression or hand movements or atleast kallu ko kuch convey kartha like likh ke ya draw karke
We are also shown in previous epis moksh ko Hindi and English minimum likhne athe he
He wouldn't have let meena aayi go like that
That means he believes she did it
Then I don't think harthak plan he
Those who sees today epi will understand
It is clear that though sarthaka loves Malhar he doesn't seem to love moksh may be he reminds him how anuyani cheated him and played with his emotions
He was harsh on Kalyani get it but he didn't show even an ounce of compassion towards moksh
Then Malhar ka cremation nahi huva do sahir si baath he probably during postmortem he was found to be alive and saved
Avni is behind some property is sure today
Lastly if we see anu reached in search of Malhar moksh in jungle
So sahir si baath he kaka and police also reached there as a coincidence
The team with sarthak was same team which went behind Malhar Saurabh pawar and two constable
May ve they brought kaka along with them so that they can trace easily as kaka clearly can understand malhars thought process more than others
