Edited: I had written a long reply and then I saw your another comment. So editedđSai 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.
