I don't think even the cv's are clear about how they want to progress this story. They don't give scenes of Purvi missing or even thinking of Pari and then suddenly she is having sixth sense that something is wrong! They need to link up story better. I know Purvi keeps her feelings bottled up in contrast to Ovi, but still, at least they could have shown her remember Pari in private!
Ovi is shown as attached to Pari and also angry at Arvi. She has already decided she is leaving to pursue her modelling career but surely she will not leave without some tamasha judging by her expressions today. But she will miss Arjun and Pari and am sure she will be back otherwise why would there be an ArOvi rain dance scene coming up. She wanted Arjun despite him wanting Purvi, now it will take her time to accept Arjun with Pari but I feel she will.
