OMG yet another mystery with the Rane family - it will somehow be related back to the Deshmukhs. Going to become a situation of the Deshmukhs vs. Ranes again, except this time, the Ranes will be in the wrong. Seeing how nice Kalyani is being to everyone, I think Kalyani will choose her own family and Malhar will have to make a choice.
Also, from the way Ahir saved Kalyani today, I definitely get the impression that he will start liking Kalyani.
