Aneri's line is what creating the confusion. She told directly that the family knows about CM.
May be KN aren't in GH when the truth comes out? Viraj or Sumit tells about CM and FJ to Dadaji and others and through cousins KN gets to know?
Let's come from first...😆
It's next day. Nisha is at home crying. Viraj comes. And then Kabir. KN probably accuses Viraj of playing games and Viraj tells it's Kabir who is playing. Can we assume, that Viraj has created some confusion then? Probably he is the one who exposes FJ and Kabir going to leave with jewels in three months?
Now..You are right...how can Nisha be at KNH then? So she hasn't met her family yet after they got to know CM? Truths getting exposed in GS instead of GH?
So Sumit calls Viraj and tells about FJ and makes Viraj point at Kabir and saves himsef?
