Is this a swift move from Mohini to create rifts in the Virani Family..
She knew that being wife to Harsh was getting her nowhere..
Maybe she felt her best bet was getting close to Sahil..
So her first step is to take advantage of the gap between Ganga and Sahil and increase it further.
Still not sure on what her complete gameplan is but it looks like she can make the most out of a rift in the virani family..
