I feel like in order to show a Malhar redemption/apology track, he will have to come close to losing Kalyani.
I fairly sure the CVS won't show KalMa officially separating, but I think he will be led to believe that Kalyani wants a divorce. Malhar only seems to get his senses back when he is about to lose/loses Kalyani.
Even in S1, he only realized her worth when their marriage got annulled and she was going to marry Atharva.
From your mouth to the CVs' ears. I really wish she'd leave his home and go line in her quarter like before without looking back. Take Anu with you and let the two awful idiots deal with the fact that Pillu won't be easy to handle without his mumma and Meena Kumari Aai. Even then, I do want a non villainous TMA to be brought on for Kalyani.
