One thing I have notice with the character of Sugni is that she never say "SORRY!. I am not talking about her apologising to MT, that she had no chice and even when she did say it she followed it up with : " We did what we did to Save this family" (so she turned it into ,be grateful to us!)
There is never any remorse/ shame or guilt on Sugni's face. From the beginning of the show.
* She walkes out on her MOTHER for TVS, she went so far as to tell her mother she was not invited to the wedding... Then she found out about Reva and came back home. Not once did I hear Sugni say "Maayee I am sorry I was disresectful and harsh to you, Maaye forgive me"
* She goes on to get engaged to Adi , then realizes that TVS loves her enough to walk away. She gets Married to Adi... Not once did she go up to TVS and says : "Thakur Malick, I know that i hurt your feelings, I am SORRY for what I did. Please Forgive me" ( Had she explain what ever twisted logic she is using for her actions and apologized in a genuine way he might have found it in his heart to understand her and maybe eventually accept and forgive her, as he once told her, She never tries to understand him at all)
* Adi and Uma (jiji) are on Shaky ground, Sugni never once went up to her or any of the other women of the house and Says; "I am the cause of this I am sorry for all the trouble this family has seen"
So I would say Sugni's pride is preventing her from seeing her actions as wrong!
