Feel like this track will encompass many different things. I think the CVS will really show Malhar's love and devotion for Kalyani, cause that's the only thing that will convince Swara that Malhar is different from the rest of the Rane men. And only then will she spill the truth. This will be a long track- we have yet to even see everyone's true faces (Bapji, Anusuya, Ahir). I doubt even that the car clue is a real clue - might be placed there to mislead Malhar. But from that clue, they might find the real clue. Also seems that Anupriya will digging into the truth and involve Kalyani, and they'll discover what happened on July 26th. This raaz is a long and complicated one, only Bapji, Anusuya and Swara know the full truth. I think everyone else will only know or knows the half truth, Sarthak, Anupriya and KalMa.
Don't think that there'll be another MU, but I do think that KalMa will be on opposite sides of everything, might also be literally. Seeing how nice Kalyani is being to her in laws, I feel like she'll be betrayed as well and side with the Deshmukhs in this feud. For once, the Deshmukhs will be right.
The raaz will be related to the past and present, and it will be related to the Ranes and the Deshmukhs and Malhar's mother.
