From the beginning Raghav should never have been referred to as a Don. He is a business Tycoon and that is what he should be referred to as.
The writers wanted to portray him as a Don with 1 visit to the night club.....Don is someONE with a gang full of people with tattoos. But the only gang Raghav has is Farhaad and Harish. Raghav is a successful business Tycoon who takes advantage law and system loopholes.
If he was a Don why would he race to the court to get bail for his mum and sister.
