one more thing I observed is how Virat was empathizing with Mohit when he said that he cant bear if his wife cheated on him. He had same emotions when he thought Sai cheated on him :D so he was like "Yeah bro! it hurts. I feel you" kind of face.
That's his karma that Mohit is facing... He couldn't and still can't bear the thought of Sai cheating on him while he has been cheating her for years with no introspection.
