I agree somewhat! Amrita is a mother whose daughter is missing for last 3 weeks! She wont be in a mindset to go help others solve their marital problems or observe Karva Chauth etc.
I thought after getting that frantic phone call from Trisha, she would be waiting by the phone 24/7 instead of running to save Lavanya's family and kids!
Helping or looking after Bobby and Meghan in her own home is understandable as shes equating them to her own missing daughter who was also having a troubled life...since Amrita couldnt do anything to help Trisha shes trying to compensate by helping Lavanya's kids.
They are making Amrita a typical Hindi serial heroine who goes around solving other's problems while her own life is in a mess!
But Im sure when she finds out abt Prateek's affair, she will break down completely, she will also realize that Trisha knew abt it and blackmailed Neha to get what she wanted.
