I think he has realized that had he listened to Kumud, his life would have been much better today and he regrets his actions. But he also hates Saras and doesn't like to see him and Kumud together!
I still think he's a master of disguise and the reason he created a scene in front of the villagers is to show them that he cares about his wife but she doesn't care about him. And the reason why he smiled when the police called Kumud is that he knows that Saras hid the truth from her and once she finds out that he knew all along, she will be angry at him and might leave him...
He's not doing all this to hurt Kumud.. he's doing all this to hurt Saras because he never let Pramad get away with his misbehavior with Kumud!
Pramad is a swine.. Na mare aur na markar chode..
agree and his anger will be fueled when he will find kumud so much in love with saras...coz she will freely declare it.as now she is afraid of nothing from pramad
plus now pramad is building social pressure on kumud to come back..by declaring her as his wife and faking out the support to her .coz he knows its only way to win back kumud...he is trying to follow saras path 😆...Alas! his pol patti will be out in open soon !!
