Yes, she is quiet so that DM will not suffer the shock of the death of his son😭 and see now she is suffering.. DM open your eyes and see how your San..tu..di is suffering😭Santu is not protecting Moti....she thinks she is protecting DM from the pain and sorrow he would feel when he finds out that his son is dead and that the wife he adored and the sister he looked up to betrayed him by keeping such a big thing from him.
