Although i doubt this is the case...more like she's going to do everything to achieve her life's ambition - make Saloni miserable. She'll probably team up with Urvashi and cause havoc in Saloni's house.
For once, Samar's speaking sense when he says given the oppotunity Kaveri will strike again with her wicked plans.
Why oh why is Saloni trying to be such an excessively good person? Real "good people" realise when to leave well enough alone but this woman is inviting trouble into her own home! Is she that bad a judge of character? Not everyone can be "sudhared"...
