I think everyone is forgetting a very important piece of evidence: Ananya Ritesh conversation in the hospital. 🤓 Shekhar, Tani, Neelu and Kuhu-all four of them were present(i'm talking eye-wise..for all we know anu was listening too) and all of them heard what Ritesh told Ananya about betraying her for other women and usurping her father's property through dishonest means. Neelu is currently not in a position to speak, Kuhu is too young to testify-any lawyer can say that she is a young child and was therefore easily influenced by 'someone' (aka Tani) to testify against her own father, Taani is anyway in a precarious position because of her mahaanta 🤔 which leaves Shekhar. Shekhar is easily capable of nailing the case. The lawyers might say that Shekhar is lying or that Ritesh said it all in the heat of the moment, but then, no matter how psycho he was towards Taanu, Shekhar was a good father to Ananya and no good father would lie about his daughter's last words. If Gulaabo tries to pin the blame on Taani, Shekhar can ever say how Ananya asked Onu to promise to marry Taani, and Ananya herself said that Taani would take good care of her kids....so you see..you can use all of this as evidence. 🤓
If there are any loopholes in this theory do say. 🤓
