Thanks for the update.
Why cannot Natchiar put Ila in place - like tell her very strongly to behave, else she will have to move out of the house (or something like that).
Also, it is so un-natural for the first wife to "really" like the second wife and her children. Here, natchiar is so loving and caring for the second family. Hope they show a reason for ayya to have married again and the reason for reason for Natchiars love. Let's see.
