Purvi knows that Ovi is Archana's daughter so I think now if Arjun will try to tell everyone about his love for Purvi she will stop him. She will be mad Arjun but then she will understand him. She would not want to take away Ovi, her sister, and Archana's happiness. She mentioned to Arjun many times that when it comes to her family her happiness does not matter. And she can do anything for her aai-baba. Purvi will be sad but Archu will think she is sad because she knows now Ovi-Tej are Archana's daughters. Archana mentioned that Sulochana today at the party. Now Punni will become handy to bring the ArVi's truth out. Lame! But Ekta may not have any other creative idea.
