Hi guys,
I just had a thought. There was a fatal flaw in Zaib's plan to get revenge on Krips. By revealing that he was Angad, he lost the upper hand and psychological advantage he had over Kripa. A little part of her would always be vulnerable and wonder if that really was Zaib or Angad. By revealomg himself Angad strengthened Kripa's hatred for him further and she resolved not to let him ruin her marriage to Satan.
