See they have to show the emotions changing. Virat is losing it. He has hurt Sai too much!!
Now if pakhi, having Vinu to her, shows rights on him ...he has to lose his shit. For once they can show him putting her in place. She got Vinu, so she should leave Virat. But she would want everything. Thats when Virat and family have to move towards sai. Pakhi's real mamta will show up. She wants vinu or virat? If Vinu eventually goes to Sai, as shown in the promo, she will beg for virat's love. She has no self respect, so she will again blackmail and threaten. Thats the real test for Virat.
I dont know how she will lose Virat though. Like Moor said, she must have orchestrated the marriage. But even then, if she is mentally unstable, will Virat let her go? It is counter intuitive. Or Pakhi should eventually give up Virat and divorce him. I dont know how the marriage will become null and void.
From Virat's reactions towards her, he genuninely thinks she is suicidal. So even the orchestration of marriage comes up, he should stay with her. Otherwise she will die no? Virat is in quick sand. Only way out seems to be the donation from Pakhi.
This is what I initially thought- V is torn between heart(sai) and mind (P) his heart wants Sai but his mind is focused on P as shes unstable. Again I dont think V is giving Vinu to P because he feels she's his rightful Ma its more to stabilize her mental health and to ensure Vinu stays with his family in CN. I also thought that if Vinu goes against sai which looks like he will (not so much hate her yet but not choose her) then V has to indirectly be on Sai's side. But the more he pushes Vinu towards Sai the crazier P will get no? so how they will show this I don't know. but for the story to evolve someone has to be on Sais side or else nothing changes and theres no story and like you said once Vinu gets pulled towards Sai then maybe V will have to be pulled back to P through her dramatic psychotic actions... how this cycle will end I dont know but I really dont want P to donate V thats just stupid
