It's obvious from the way Murari acts that Manyta's life is in danger from the royal family and that's why he had kidnapped her 16 years ago and has been on the run ever since. My question to you is who do you think is endangering her life. Here are the candidates:
1) Dadisa: She has shown continuous affection towards Manyata's by keeping her birthday gifts in a closet and continuously going through her childhood pictures. When everyone tells her to give up on Manayta's return, she does not want to and keeps the hope alive that one day her granddaughter will return. And who can forget the room scene in which they talk for the first time. I will laugh if the ultimate twist is to make her evil and she wants Manayta dead for a particular reason. I WILL SEROUSLY LAUGH.
2) Brijraj: You know he has fatherly affections from the way he acts with J yet whenever the question of Manayta or her return comes up, his mood suddenly changes. He has always encouraged his mother to give up the notion of Manayta's return and to give everything to J instead. He is a very power hungry man from the way he fixes alliances. Also when the news of Manayta's return came, he was not very excited which could because he believes that it is another false alarm nor has he shown any fatherly affection towards her, why? He could have had his daughter kidnapped to protect her or wants her dead ultimately.
3) Komal: She has shown a lot of affection towards Manayta despite the fact that she has never been around for the last 16 years. She had also been accused of being a lousy mother to J because all of her love/affection belongs to Manayta. There is no way this woman wants her dead. She grows teary eyed whenever the topic of Manayta comes up.
4) Uday's dad: He is very power hungry also. He does not care about which one of Brijraj's daughter his son marries as long as she brings with her the ultimate price. So, I don't think he would want Manayta dead with everything under her name. He would rather have it all through his son's marriage with her.
5) Bua ji: There is not much we know about her aside from the fact that she along with her husband wants the throne/property/money for their gossip queen son. She could have planned it or not. Also, she was quite eager for J and Uday alliance, wonder why?
6) Some unknown character who has not been introduces yet.
