Prithvi doesn't react at all to seeing the woman who is doing all this tantra, whose name is revealed as saudamini in this segment. His reaction is as if he has met a stranger, so he doesn't know her. So that means that evil woman is not niyati's mother. That much is definite. The girl nisha who nirvaan is in love with is saudamini's daughter. 😲 They haven't said it but I'm sure this nisha is evil and is trapping nirvaan for her mother.
Now what I think is that kanchan's mother is niyati's mother. That's why kanchan lied to her mother about the niyati's family name when kanchan's mother became tense when kanchan said she got a job at a party for one of the richest family's over there.
