I have a theory on the next track after Vinu gets better.
Sai will be about to leave Nagpur again, much to the relief of the Chavan’s. Somehow, it will be revealed that Sai-Virat never took divorce and so, their marriage is still legally valid. Pakhi-Virat’s marriage automatically gets annulled and the whole family is in shock.
The court will order Sai-Virat to give their marriage another try, and Sai will be legally required to live with Virat for 6 months before they can apply for divorce again. This will make Bhavani’s foreshadowing of the three of them under one roof come true. It will also give a jolt to Pakhi and she will start turning negative.
