Immediately once It gets proven that Rishi is Ricky the another question cames as Why hes staying here ! Sam knew very well That Rishi was never behind that property Still he said so only ! May Bcuz He wanted to create problems B/w InShi and CV's wanted Vidit's Mystery to take time to & reveal later.
So The real reason for him staying at SN is still not revealed ! How convincingly They avoided to take out that Truth by giving another Twist ! 😛
