How did Indira escaped from her Funeral?

The story till date clearly indicated that mentally challenged person is Indira.The proofs cv's showed is Indira recognized rishi's voice in phone,later when Rishi was standing on the orad,she ran to him and hugged him and when she was taken to the hospital there also she called rishi.She remembered Rishi.If she is not Indira she will not remember Rishi.Moreover cv's showed that she has BT and due to the funeral her hand was burned.

But the mystery still remains.Was Indira out of her coma?Or there are some more events happened in between which Zara ,rishi and Sn need to know?Bomb blast occurence is also needed.Thats how zara forgot her past.

zara must have another face /story before Bomb blast and MK must have manipulated things.Zara and Indira had some connection def 8 years ago which made zara get indira face and Indira landed in Pak jail.

Hope mystery resolves soon.

Still there are many confusions which needs to be cleared.

Hope Rishi and Zara both solve this at the earliest.
