I myself was disturbed by the treatment of Purvi.They all behave like typical narrowninded low-class people.
Ovi never claimed her as a sister until her tirade with the allegedly betrayal issue.
Manav has treated her with scorn. Savita openly insulted her in the market wit such scorn.(Typical low class behaviour... can't believe she lived in Canada for 18 years!)
Sulo now realizes she is an orphan and her real grand daughter is Ovi!
DK looks on silently and I have the hope that he will get a voice and defend Purvi and his son... he has let Manav take over everything... his business and even his domestic life.
As someone wrote, Purvi's parents may be the richest in them all.
