Yesterday's episode made me doubt Kinjal. The reason to shift to Narvekar's house seemed a bit lame. Also what about her grandmother? In one of the first episodes they showed an elderly woman in her house. What happened to her?
Kinjal will not be a negative character. I think she is being blackmailed by someone to keep an eye on Narvekar. Maybe the grandmother was kidnapped. Given that she is the only family left, Kinjal will do anything to save her.
Just like Dhwani's stalker's story has not ended completely, I think that there is more to Kinjal's story, not just about the love angle between Narvekar and her.
