We saw that in the precap, Kaku is asking Sai to do the ritual where she has to change her name, probably surname. And I'm really not going to talk about whether Bhavani is doing this to get back at Sai or something like that.
I feel that the precap, along with Bhavani's way of getting back at Sai, is also showing that she's in a way, accepting Sai into the family. She can't expect Sai to change name and become a Chavan bahu, without her accepting Sai.
Even if it's not a wholehearted acceptance yet, it means that she is coming to terms with the fact that Sai is Virat's wife, and hence, whether she likes it or not, a part of the family.
I'm really looking forward to the episode tomorrow. And I'm quite sure that Virat will also be insistent to keep it as Sai Joshi.
What do you guys think about this?
Love,
Niya
