Though Prakash now knows who he is he cant charge off to go butcher Ashvin. He is poor penniless and has no power.
He is not a saint, he is bitter and cynical thats why he used those words for the hawker.
He is wondering how to share with his daughter
He wants to understand what she thinks of him
There will be no melodramatic parda faarsh type scenes
When she finds the truth she will not go to Bangalore
Going to Bangalore AGAIN without knowing the truth is plain stupid
She wont go to Bangalore for now.. lets just say that.
Ashvin's plot has to be revealed. Everyday people dont punch each other or threaten nasty consequences. If Prakash promises such a thing how will he even carry it out?
He knows his daughter is a changed girl now. That makes it harder for him to come out and say it bluntly.
He will tell her in his own dignified way soon
