I think they are going to frame durga of having an affair with rajesh, she will go to see whats wrong with rajesh wife but she will die.
They really made this bade papa evil, with this framing her, getting her married to an old man, manipulating an innocent girl. It would have made sense had he not gone to such an extreme, he could still have gotten rid of durga but he could have looked for rishta for durga from city or overseas and when anurag is away have the meetings and wedding. Durga would have anyway have had a hard time denying him with how she sees him.
