Ashwini is also annoying me in this track, particularly with the OTT reactions and acting. I also hate that she is emotionally blackmailing Sai to return, as she has done previously and continuously. She never spends the same time trying to lecture Virat to understand Sai. I agree she is very much Virat's mother and Sai's MIL.
That being said when I stood back to think about perspective and the story telling what she said today, in light of the recent tracks, made perfect sense and was in character. She has known PK has been an issue in the marriage, which is why she continuously used to make comments about PK earlier on and before Samrat's return (e.g. the one about her action in tearing up the Ladakh tickets leaving questions in everyones mind). However, after the accident track she called out both Virat and PK in the room and Virat confirmed to her that he is thinking only about Sai, who he accepted had carved out and earned her own place in the family and he told her he did not want to speak to PK, but she came there herself. The next major event was the cafe incident when Virat said that he is not living in the past, he has moved on and only considers PK his friend (itself problematic IMO). So, what she said today is what Virat told her and the family. She has no reason to, and Virat is not shown to be in the show, a liar or dishonest person (his actions are questionable but not dishonest to the audience who know his pov), doubt what he is saying. During the fights where Virat and PK were harassing Sai Bai, Sai did not reveal to Aai about what she thought about Virat and PK and PK's sick intentions. Sai did not reveal this to anyone other than Virat and PK, and Samrat overheard. What Ashwini did witness is Virat locking Sai up, but not knowing the reason behind it. Sai never shared how she was feeling with Ashwini and neither did Ashwini check in with her and get her to open up (itself a failure on Ashwini's part). That is why she made the comment about Virat becoming like Ninad - this was about him locking her up, not what he was doing with PK because Ashwini was not aware of PK coming into the room and ganging up on Sai.
Now, I am not saying Ashwini is not at fault for not looking deeper at Sai's troubles and depression, nor am I saying she right to ignore what Dr Anjali said about PK being an issue (Dr Anjali IMO looked slightly annoyed when she tried to brush this off), but her response that it is in the past and Virat has cleared it is right from her perspective because that is all she has seen, heard and has no reason to disbelieve. She has not been privy to everything else that had been happening. As I said, that does not mean I think she is right or that she does not carry any fault. She is not and she does. She is also frankly disgusting for emotionally blackmailing Sai, rather than trying to understand and support her DIL. However, all I am saying is what she said today is entirely consistent with what she knows. That is why when I watched the clip a second time after thinking about it I was slightly less irritated.
