Ashwini's acceptance of Sai as Virat's wife and her 'sunbai' comes from her love for her son and her overall compassion. As she said, she knows Virat will not bring a "wrong" girl as his wife into the household.
What i cannot wait for is the bond between Sai and Ashwini. I can almost picture one scene where Ashwini will ask Sai to address her as "Aai". It will be the most emotional moment for her, I believe.
Has Sai ever addressed anyone as Aai? Because she mentioned to Virat that her mother passed away at childbirth. Also the word 'Aai' will remind her of her Aaba- for being her Aai and Baba both as well as for the banter they shared where he would constantly call her 'mazhi Aai'.
Like Bhavani said Aai jaisa hone me aur Aai hone me farak hota hai. We know Ashwini will be a doting mother to her sunbai.
I think among the many terrible things Sai is going through, the one thing that she will later thank Virat for is bringing an 'Aai' into her life.
Please share thoughts!
Have a lovely day
