So the only thing left is, as you said, to make it a sasur-damad show. It was brilliantly billed as a show about messages about the treatment of midgets (I don't like to use the word dwarf, since it sounds like an alien creature out of Snow White) but actually a very well disguised sasur-damad show. And it's been thru quite a few phases - first Murli refusing, then agreeing, then marrying, then being supportive of his sasur and being shy about taking favors from him, then rescuing him by giving him back his money, then starting a business together, then having this fall out and now in full war mode.
So Murli is now, in a reverse way, what Sandhya was in RS: she was in full revenge mode against the Jagirdars for having used their riches to ruin her family & her, and now Murli is in that mode against the Chauhans for subjecting his family to that. (Okay, I recognize the comparison is somewhat odious - Rupesh is certainly no DK or Prabhavati) So he's firing on all cylinders. And I think it has to succeed for normalcy to return - so far, only Murli's side has been humiliated, but not Rupesh, so for any peace talks to even start, Rupesh has to start revealing to them what he found out about Prakash, but that he will only be forced to do once Murli has the upper hand.
