To be honest, kuch bhi nahi hoga. Angad ke hisaab se Sahiba is the mastermind of everything wrong happening in his life. In the OG, Riddhiman wasn't so vehemently opposed to Khori. He blamed the entire family for the fraud. And his feelings for Dyuti wasn't bigger than his family name.
What I am thinking is, does Angad think that with Seerat coming back, he can blame Sahiba and have Seerat back in his life conveniently? Kyunki uska attitude aur baaton see yahi lagta hai.
Sahiba, on the other hand, wants to be honest with Angad. She wants him to know the truth. But considering her situation and how Angad perceives everything, why will Angad and the Brars trust anything she says? Why will they believe Seerat and Sahiba over Garry?
I don't see how proving her innocence plays out here. Also Angad has walked down the anti-Sahiba approach for so long, with the notion that she is a criminal, fraud, master manipulator, how will the truth impact him?
To be honest, it should shatter everything within Angad, for him to become a better person than he is now.
