We know he mentioned Bhau and shaitan, etc. How Naku had to help Bhao find the Bhagwan inside. I do not think Kishore is the BH, but playing shaitan's advocate, here are thoughts worth thinking about:
how come kishore has never tried to undermine his wife and expose her in all this time? aside from threatening their son, why would he not want to? He's an enabler of sorts, allowing her to do things that will HURT Bhao.
I loved that he supported Naku, but was his motivation not so pure? The more Naku confronts Dutta, is in his face, the more upset and violent Dutta would get?
When Kala was about to "shoot" Naku the other day, did he have another motivation for wanting Naku alive?
And finally, how can he, as a person full of faith in God and being kind, live with Bhao and benefit from his dealings as a Don?
Again, I find it hard to think Kishore could be BH...but I thought why not? What do you think?
