i dont understand why every one only blames ishwari to be toxic. bijoy might be a great dad to sona but seriously he sucks as a grand parent. i will never support him insulting Dev infront of Soha.
whatever may be his hard feelings for Dev, he has every right to express them, albeit in the absence of soha. if a separation happens, both the spouses will be responsible for it . its never possible that only one of them is at fault while the other was a mahanata ki murat.
coming to kids, NONE of the families have a right to degrade either of the parents. if they cannot respect them, let it be , but you need not deliberately stoop down to insult them right in front of their kids.
Agar bijoy is angry for Dev insulting him in front of his wife and kids, he too is doing the same by insulting dev in front of his daughter.
both the head of the family ( ishwari and bijoy) are toxic in their own way to Soha.
having said that , it is also essential that the current arrangement of 8 -8 is much needed one, for exposing the parent to know how to take a stand for their kids and their spouses. anything concerning soha was, is , and will be something for only dev and sona to decide. the grand parents from both sides can never get to decide , they cannot be involved in the decision making
