How did Simran die exactly? I was thinking, suppose Aanamika and Simran were together at the time of Simran's death but instead of Simran, it was really Aanamika who died. But, due to the cause of death, (supposing the terrorists used a bomb or something), both women's faces were damaged and so there was a case of mistaken identity and doctors gave Simran Aanamika's face during surgery. Also the um...cause of death could have caused amnesia! so Simran only knows that much about Aanamika which Aarti's family must have tried to remind her of... But upon seeing Kaushik's house, it's all coming back slowly... 👏
just my wild imagination taking over...😆
The theory that it might be a ploy of Aarti's sounds more realistic...
