Proof is there but..

Now the question is how to prove she is not Natasha as Mr oberoi has proved it lately..

yug is Real Nats husband and has proof of it too..wedding pics..marriage certificate..

Next blackmail you tell the truth i will kill your husband Agam.Nimrit is in big dilemma on one side Amrit and other side Yug..she can prove she is Nimrit but will think twice as her weakness is Agam..she can bear any torture but not Agam hurt or something happening to him..this is ruled out ..She will be in a fix also if she accepts to be Natasha but she wont let Yug get what he wants..property of Natasha...Mr oberoi has saved her life and has lots of gratitude towards him so will do anything to protect his real daughter money and property..

As Agam is the husband of Nimrit i think he is the one who can get her out of this mess..At first He will be in thought and heart broken as no matter what he has feelings for Nats who is his Nimrit..the protective attitude is there and we saw it in the Epi..btw Agam should go down memory lane as he knows Nats is left handed..loved car racing..champion in swimming total opposite of this Natasha..to give a thought of why Natasha keeps saying she is not Natasha oberoi..

Agam always share his grief to his mother so keeping a hope he did so again..he loves Nimrit a lot and loves his mother same..like sunita revealed Agam's truth to Nimrit hoping she does same about Nimrit's truth to Agam..He will trust his mother and Tej also can join in to plan something against Amrit and Yug..one thing in their advantage Amrit does not know Nimrit has revealed her truth to her M-I-L and Tej knows about Agam reality of why he married her..

Crossing fingers creatives bring such a scenario where the two brothers once more work together for the downfall of Amrit and save Nimrit from their trap..
