I just don't get why she doesn't doubt Pia's words or look deeper into JW's actions. I don't like that Bani believes Pia but forgets all the things JW said to her.
Jai had no reason to go through this trouble> he could have married Pia anytime. didn't he once ask Bani for divorce & even took her to court during Anu's pregnany. He couuld have done that when he knew Pia was pregnant & Bnai could give him kid. But when its JW Bnai has very low tolerance & trust.
