oki Kaaki .,.related to Kaveri ..?

I think .. Kooki kaaki and kaveri .. sort of know each other coz once .. kooki kaaki was talking to some one on the phone and she was saying to them .. I will complete my work here .. of making saloni's life misearble .. and defaming her name in thew sasural .

Now who else wants .. salonis name ruined ... and can be talking on the Phone ... Cant be aditi .. for she can speak in person . Its got to be Kaveri

what do u guys think?
