I have few guesses on how Sinha's so-called brilliant mind will work to end Astitva...
Let's see -- Yash will learn that it was his own mother that brainwashed him against his father. She was infact an adultors and uses people to her benefit. The only good thing about it is that - she's not biased... She didn't even spare her own child... That should definately count for something. 👏
once's all this is out - Yash will admit all the things he was "forced" to do by his mom.. i.e., ruin ANH, removal of Shankar, Urmila and poor Sakshi. Also, the framing of Sid will be out. Simmy will give Abhi the look (now that she can see with Sakshi's eyes) of "see I was right" Sid bachcha is good bachcha... :-)
Abhi will ask for his apologies -- and so will Saurabh (maybe)... Simmy the great -- will shower Abhi with her greatness and forgive him... Simmy, after seeing the changes in Yash, will ask Abhi to accept him his son and learn to love him...
The END!! 🤢
