Well, I was wrong, it is very much a Virat-driven story. All possibilities hinge on his decision, actions, and reactions. Sai may be the star of this and Patralekha the conflict, but everything that is taking place in the story -- and whatever happens tomorrow -- is because of Virat.
He is angry and lost at the moment, but he will soon remember, "hamare bache ko bacho" and that is when he will start investigating and hopefully end up where Sai delivered the baby. We still don't know whose name she gave in the document. We will find that out along with Virat. Today's episode again made Patralekha inconsequential. She had her moments to shine and take the center space, and she may appear important for some time more, but story wise, she will start to recede now. With 7 days a week telecast, we may get to see more of her long scenes with Virat and other family members. But she is not important anymore.
I hope when Gulabrao and his henchmen attack Sai, the village chief and village people should come to her rescue. What was the need to show her winning over the hearts of the village people if they do not show up? Or was it just for the dawat and the post-leap first meet. (If writers remember, Sai may get to build the hospital with Bhavani Kaku's).
