Meet my wife Mrs. Tia Singh Oberoi just like that, even Annika had stepped forward then!
Secondly, I don't connect with Pinky assuming herself to be the one Shivaay meant. From the start of the show it was Omru, Dadi, Prinku and the rest of them. Shivaay never had a special bond with his Mom. Yes, he was diplomatic and he loved her too. But Pinky was more interested in making loud comments when Shivaay added zeros to his bank balance. For her, Shivaay was more of an asset, the only asset that brings respect and equality for her. Just like Tej said once!
They had a possibly distanced relationship. Even before when he was sick or hurt, it was Omru and Dadi who cared and nursed him back to health.
In Annika's case Shivaay is actually guilty, eventhough he doesn't show. The need of finding Annika just beside him as he opens his eyes, it maybe more of a fear than love. He fears that she'll abandon him and go that too without a word. Maybe when he is unconscious or sleeping, just like the other two times. Because of all the terrible things he had done to her. So he tries to make up for all that with this excessive care. And that too when she has taken a bullet for him!
Moreover he had always been a brain person, so now as his heart has fallen deeply, madly and irrevocably in love. It is possibly doing gangaaram of his brain and other senses!
So if Pinky Mom is gonna induce a separation then she is gonna see a cold ruthless version of her heera beta who will go into any extend of self destruction!
