I'm confused as to why Abhimanyu is the real boss, or rightful heir to the company. It seems like Dev hasn't taken the father's seat and is waiting for Abhimanyu to fill it. I always assumed they had the same father and different mothers, so even if they are half-siblings, Dev is still the older son with more right to the Raichand family business. I guess it was never explicitly specified that the mom is his step-mother (although she seems way too young to be his real mother). Does anyone have any insight as to what could be going on there? Could it be that the picture he talks to is actually his step-father, and he feels like he has to take care of his half-siblings because their father probably accepted him even when he wasn't his actual kid?
