Glad that Saraswati finally realises it is unfair to separate Pinto and Krishna who love each other so much.
As you've opined I also think that TTS will refuse to accept Krishna.
I think he is more infuriated that Prishna has won the contest than he is upset about his grandson Sonu. He is so wicked that he is bent on ruining Krishna and her family. That's why in league with the Biharis he is seeking every opportunity to destroy them. Oh sure, we're going to have more drama. The serial has to move forward, the evil ones will continue plotting and the honest ones tested in life.
