I was getting real down @ the thought of Sudha 'returning' Murli to Bharti. Like you say, you'd think Murli is a doll that's passed from Bharti to Sudha & now back. Yeah, Murli feels guilty about the way he treated Bharti, but that doesn't mean that he wants her, just that he wants to do justice to her, if possible.
Thankfully, the abduction happened, and tonight, Murli, after freeing Dhara, will be hunting for Amarti. Once he rescues them, his guilt will be lightened, and I hope that he doesn't then ask Bharti to return (b'cos I'm scared that being a complete doormat, she'll ignore Amit and go to Murli). Hopefully, after it's all over, Murli & Bharti are free of any guilt feelings or debts for each other, and hopefully, Bharti tells Murli that she forgives him but has decided to move on. Or alternately, if Murli gets injured in the rescue, Bharti will feel guilty about wanting him back when she knows his heart is not in it, and it's only guilt that's driving him that way.
Vaishno Devi temple is in Jammu. These people are in Agra. How on earth does Rupesh return in time - Prakash was right!!! So hopefully, it will be Surli, rather than Mupesh, who save Amarti. Or Murli might leave Sudha to take care of Dhara, while he goes hunting down Prakash.
