Duplicate Shetty is clearly obsessed with Umar. He can use this to his advantage and fuel this rivalry which would take him straight to finale.
This is his chance to take the center stage by locking horns with the chosen one of Bigg Boss just like his brother Asim.
But for that he also needs to be ready to face constant bashing and biasedness from the host and Bigg Boss. Because they would always support duplicate Shetty just like they supported Shukla in season 13.
If he can take that pressure, he too would get audience support and sympathy like Asim.
