Ghum timelines are messed up.
Or else now that Shruti mentioned that she has been married for 1.5years I could have wished for Sai to question Virat if she really needed a divorce, because if he was already married to Shruti then Sai’s marriage to him does not hold any legal validity. I would have wanted to see Virat’s response to her, when she is feels that she was living with an already married man without having the marriage legalised. How much more would he traumatise her with his mahaan tyagi tag?
I guess here she would go for annulment, not for her own sake, but for Sahas. To give him his father’s name and a family.
Virat can stay a life of celibacy with an adopted son and wife in the name of zimmedari and Pakhi can keep panting and feel some content that her curse has come true. If she is not happy neither should he. If he is not mine he should not belong to anyone else. And without his own willingness, destiny helped his stay true to his promise to Pakhi.
