This is how I think Purvi's character will develop:
Scenario # 1
Arvi reunited with their son, Archana dies. Purvi faints during the funeral and the doctor declares that she is pregnant again. Everyone believes that Archana is returning. 5 years leap. Story goes on.
Scenario # 2
Purvi gives her son to that stupid Ovi. After that everyone in the Deshmukh clan hurts Archana a lot because the kids become selfish even Savita becomes mean. This leads to Archana's death. Purvi gets angry during the funeral and seeks revenge from them. 5 years later. Purvi is a successful business woman, she is modern now. She takes over the Deshmukh company and seeks revenge from every member but not Manav because he is mentally unstable or maybe he is vegetable due to the shock of Archana's death. She will be Arjun's competitor.
Scenario # 3 (which I don't want) Based on the new buzz about a giant leap during the summer.
Purvi gives birth to twin boys and she gives them to Ovi and Arjun. Teju gets married to Sunny and has kids of her own. Punni, Sachin, Soham and etc. all start their family. Purvi goes back to Kolkata after Onir's death, and stays with his relatives where she raises Onir's orphan niece. 20 years later. Archana dies. Purvi is a successful business woman and she gave Onir's family all the luxury and took care of his niece as her own. The niece is righteous, intelligent but slightly naive and is also a famous model. She wants to achieve success on her own not through Purvi so she runs away to Mumbai. Where she stumbles across Arjun, who offers her the position to be his assistant, and lets her stay with his family. Ovi owns a fashion industry, and she is in search for the famous model in Kolkata so the niece changes her name so Ovi won't recognize her. There she falls in love with one of Arvi's twins but she is going to end up with the other who doesn't believe in love. Everyone in Arjun's family loves her even Ovi except for the son who doesn't believe in love. Purvi comes to Mumbai. From there on Arvi's and their sons' love stories will continue.
