I think this is how prithvi will go mad. When Kripa will realize that Angad is innocent she will hate prithvi and she will tell him that she does not even want to see his face. Since prithvi already has a manical streak to him, he will tell her that if she if she is not his then he won't even let Angad have her and that he will kill him. He will try to shoot Angad and Kripa will get in the way and she will get shot. As Angad is holding her he won't belive what he did and at that point go mad seeing that he shot the love of his life.
What do you say guys?
