I think Mr banerjee was framed . So Ktj can get kakasa's trust and at the same time Brijesh looses his crediblity and appears not to have ability to recognize ppl he works with.
This way KTJ kills 2 birds with one stone. KTJ is definately more than what he appears to be. I think he hates the idea that Brij and Nahar runs tthe company and may be he wants to take over. He may be thinking that kakasa did wrong to him by not giving him the charge of company and let Brij and nahar run it.
what say?
