If she had required his sorry, she wouldn't have said "farak padta hai kyunki baat aapki hai"
If she had required his sorry, she wouldn't have moved heaven and hut to find him and then run into his arms
If she had required his sorry, she wouldn't have pictured him in her "little girl" fantasy which came alive after he said "i love u"
If she had required his sorry, she wouldn't have had telepathic conversations with him
If she had required his sorry for the way he treated her in the past, she wouldn't have been on his side offering and seeking support after glee's bubble burst.
She feels responsible for the growing rift between the siblings and she knows how important that bond is to him and she, as always, is sacrificing her happiness for his sake. She is trying to fix a relationship by nixing their own. If only it were that easy...life, especially theirs, is more complicated than that.
She has made up her mind on the solution but doesn't really understand the problem. She is not the problem but glee's bubble is. And they need to be together to provide glee the support that she needs to construct a life in the real world free of the bubble.
And based on the unsaid today, each thinks that the other knows what the motivating factors are for the other's actions. But do they really?
Does she know that he doesn't care about the contract?
Does he know that she doesn't care about the contract?
Well the next 10 serial days are going to be them finding out...
On a side note: I don't think he is threatening to expose the details of the "contract" marriage to pin the responsibility on her. When time comes, I am certain that he will take responsibility for it. But regardless of that, he is pointing out (since she probably orgot to consider that in her "quickest fix" mode) the consequences of her honoring the "end" of the contract on her family who think that this marriage was based on love. He is buying time again to get her to walk into his arms on her own. How??? I so wish I could predict with these CV's.
