The fact is we as viewers cannot relate to her character at this point of their life and expect matured behavior from her. She is still in her delusional world created for her by her superman. Even Sneha knows her well and is more worried for her. Amaya cannot just change overnight. She will take her time. Hope the growth in her character is portrayed in a realistic manner.
Rachita, Jazz and Sneha are more practical and relatable than Amaya. Overall, their family is likable and makes for an interesting journey up from the disaster they have faced.
