1. When zara came to sharma nivas...everyone was just repeating the same word that indra came back again...they didnt seem to be shocked...with the actions and dialogues it seemed that they were expecting indra to come back...may be indra was nt dead but lost..something mysty is behind it..is it possible that noone at that time was at there senses to state that she is nt indra coz she is dead? That means that somethng else had happnd...
2.probably a natural sign when rk approaches zara the gatbandhan catches fire...(natural signs)
3.zara didnt stop rishi from hugging her...
4.when zara was climbing..the stairs..indu comes to conciousness and says "mummy"
5.when zara was being touched by malik...rk burns his hand...a natural and interal bondage being shown between...
So i thnk indra is only zara...what do you thnk?
By the way great acting by Sumit Vats and rati
