In today’s episode it is proven that Rakshit is Anjaan. It bothered him that Dhristi was dying. He took hold of her head and placed it on his lap not Divya’s. I also think that is also the reason why he placed the ring on Lavanya’s finger so that someone goes in search of Drishti. Anjaan might be helping Psachini now because he might have found something about his father or to save Dhristi’s life.
Giving the gem to her means he can have a normal wife, who doesn’t avoid him. Or bring back his father since, his mother has gone completely crazy almost Lavanya’s level.
