I am somehow sure ki Avni ka sara bhanda auo saheb ko pata he
She may not be an ally but she knows it I feel
She won't let any happiness near Malhar rane but still has allowed his remarriage and him fathering a child
A child and wife will make a man normal and bring him back to life if the wife is really capable
I mean kallu did it in few months
So why will auo saheb let malhar have a wife and even a kid unless or until she knows that is his burden or responsibllty and not happiness
I am sure Avni is left unharmed and alive just as AS knows the truth
And now she see it as an opportunity to instigate Malhar against kalyani
Avni se unko faida he indirectly though not directly isliye she is alive and living a happy life.
