So many reasons behind this.. Zara and indira cant have so many similarties even blood group?
Zara is Indira and Rishi feels her presents so he isnt wrong.
Ok now i know we have seen Indira's funeral but dont you think shaweta is behind all this?
She became very Attached with rishi after giving birth and Indu..And dont wana lose them at all..." Dont forget that she is a Doctor" So she probably arranged fake body with Indira's mask so that everyone thinks she is dead.. I mean this could happen after all this is a show!! See her reaction after knowing that Indira is alive!! I hope what i am assuming is true!!
