Tikku and Dayaben

Tikku set the example to Asha and Fatima. He sought forgiveness for any and all mistakes committed by Asha and Fatima and pleaded to her inner person. Asha, Ashish and Fatima respond to her ego. Soon, we will see Avni responding to her ego. But the only way to conquer her is to plead to her sensibility.

True that!!

Fatima Banu has filled Avni's heart with hate for Dayaben,

Even though Dayaben was kept in the dark about Ashish and Asha's relationship for 12 years and knew about it recently only after she said 'YES' to Hemant Bhai re: Neela rishta, Avni is going to hold her responsible for denying her a 'normal' family and keeping her father away from her and Asha.

Fatima Banu has sown seeds of hatred so deep in Avni that Avni is going to fight through out her life with a Dadi who knew of her existence only a few days ago.

As for Tikku's humble request, he is more sensible person than Fatima it seems. As Fatima Bhanu said in one of the episodes he took care of Asha when she was pregnant.
