I had a theory on Vinu ka adoption... Pata nahi Kitna possible hai... throwing it out here... Dekho kya lagta hai 🤣
P had genuine regret at Sai and Vinus death.
Went to Mahabaleshwar to repent in Samrats orphanage.
Biological Vinu somehow landed up there.
P recognised him and was anyway obsessed with him.
Meanwhile, the kid was lost when he was barely 15 days old. Sai mentions this at the accident site. I remember clearly.
Babies undergo rapid change. So logically people recognising him seems a bit stretched.
V was lost, must have started getting over after some time. If P brings Vinu back after a year or so... then Vinu is 2-3 years old. He may be aware that he was not born in CN or he is not from there. It's difficult to explain to a 2 year old about adoption but he can guess that his home has changed.
Seeing V recover quickly after meeting Vinu and P ka true repentance, Ash asks V to marry P. By giving some kasam or something. I cannot find a logical reason yet why V would marry P... unless it's a manipulation of this level.
P all along knows that this is biological Vinu but hides this fact to keep everyone under control and keeping up her new positive image. Also getting married to V in the process.
So it is only when Vinu is in need of some genes/blood/bone marrow stuff will his parentage come out.
@msin... while I get your idea, I can't guess what purpose it will serve in the story if he is not biological.
Right now, P is attached to V in a marriage because of Vinu. There's nothing other than that which can bind them. So if Vinu is adopted, how and why will virakhi marriage break and Sairat patchup?
