Is Veera Sampooran's biological daughter?
Yes, but not Ratan's.
Where did she come from?
Her mother Amritha had a terminal illness. So she gave Veera to Sampooran just few hrs/minutes before her death.
Did Sampooran have an affair?
Yes, only once.
Where has Sampooran gone and why?
Sampooran was dejected that Ratan didnt listen to his explanationa. Also the villagers taunted his so much for doing a mistake when he was the sarpanch. So he just boarded a bus and left the place. He took promise from Ranvi to look after Veera and his mother before leaving.
What's the deal with Sampooran's friend turning up and acting shady?
Are u mentioning Kartar. If so then Veera's mother is the run away bride of her marriage with Kartar. Due this , Kartar lost his mother. Kartar couldnt forgive Sampooran.
