Watching the precap it seems HS will know of Minnie leaving for Australia but maybe Babita won't. This will probably lead to the rift between HS and Babita. There maust have been a reason for the scene where Babita took promise from HS that he will never let Minnie leave the family. And more importantly, the extent and range of deconstruction of Babita's character makes no sense if they were to show that Hanita living happily after Minnie leaves. The reason for such a strong denigration of her character has to mean that bad things will come upon her,, all for her own actions
Babita is being shown as this petty, cruel, self-absorbed woman for a reason..NB also gave the hint when she was speaking to Minnie the other day that she hoped Babita's delusional bubble never bursts.
Speaking of NB, Babita didn't even think of picking up the phone to inform her that she is selling the shop? The same NB whithout whom she might not have moved forward with HS, who was like a mother figure to her, who stood by her when her dear beloved Saroj drove her out of her home. NB probably has as much importance in her life now as the other two attendants at the shop.
