Brahma Not Aware of Gaurav's Leave?

As strong as the wall between Gaurav and BJ had stood, I don't want that wall to be ignored simply because Gaurav has left the show. If I'm not wrong, Gaurav left the country while BJ was in jail or something, no? The way BJ was speaking with Vidya, I wanted something more substantial out of it. Maybe BJ trying to find out exactly where Gaurav is. And if I am wrong and he already knows, I wish something would come out of it. Gaurav's war against his father was much more stronger than Aditya's. He had that war since his childhood, whereas I don't know what Adi is doing lately😕😆 BJ may hate Priya and Uttara, but he had problems with Gaurav all the same for ruining his reputation. I hope, even if without Gaurav, something related to that matter is brought up before the show ends!

BJ was not in the jail then when Gaurav left the country. He was caught attacking Priya when Dev and Adi left to rescue Priya and Gaurav and karan left for the airport. So he has no inkling idea where he is.

BUT the question is how come he knows Vidya's nme -- is he really mental?????????????????????
