I remember similar scenario in MHRW where the FL married ML after her first husband is assumed dead, but he returns after their marriage claiming that 2nd marriage is not valid as he is still alive. However they show ML telling first husband that that law also states if the spouse and the family have done final rites of the person and if the death certificate issued; and if the said dead person comes back, the second marriage will be legally valid.
So Pakrat marriage will hold true (not sure if Vankar reached Hindu Marriage Act), except that Virat didn't actually do the final rites but def death certificate was issued without which Virat wouldn't have been able to marry again.
I dont see Sai returning except if she assumes or knows Vinu is Vinayak.
They showed Pakhi as ideal bahu who changed Chavans with love unlike Sai the jungli bahu who couldn't change them due to her stubborn and righteous nature.
If Pakhi refuses to let Sai in and threatens to leave with Vinu if she is let in, will Virat accept Pakhi's terms, now that she is his wife? I can see the show topping charts again, it is getting interesting for audience as show can shift anyside.
