Edited: I had written a long reply and then I saw your another comment. So edited😆Sai accepted her mistake no? She is not like others, she doesnt shy away form accepting her mistake, in addition she took full responsibility, unlike others in CN family. I think to accept a mistake courage is needed and Sai has that! She is always that better person.
I also believe that Sai behaves with Virat as she behaves with her dad. She does take him for granted, in a way that she doesnt feel the need to apologize. It comes from an 'innocent' place, not from a calculated approach. So we should not blame her for that. imo
Having said that, when she is in a relationship with Virat, she should learn to apologize when he gets hurt, like in anniversary.
For example: yesterday when she saw virat in Sada's den, she immediately apologized.
Today also I did not feel Sai is shown as a victim, is she? Ultimately, she is the wife and whatever happens to him, in this situation, she will be blamed and she took the blame like any honest person. Even ashwini blamed her, for a moment. Blaming is easy, accepting one's fault is not.
PS: Look at the brothers . Sammy was not even stopping the motor mouth of his wife today. pathetic.
