She already crossed that line the day she questioned a wife about joining her husband.
And seriously,atleast an ounce of guilt,leave guilt,remorse ,for that infant. What was the child's mistake. Has she seriously even lost touch with her conscience.
Maybe ,this is the Patralekha,not what she has turned into,but she was always there. It didn't show as she was a pampered child,who got enough independence to select her choices,got everything she wanted. Even here in CN(although it seems as a facade) But she is getting what she wants. But ,the face which is now coming out,when she is not able to get what she desires is the reality. Inside that independent ,educated ,mature woman which she shows or maybe she thinks she is,that is all a lie. She is selfish human being ,who just wants to possess what she likes ,that's it. Then it automatically seems like ,it was not love for Virat but was a greed to have him,just like she got everything.
