This happens when u get more than u deserve. Till a day back she was yearning to meet her grand daughter. Its so nice of Sona that inspite of knowing Ishwari and her antics, she still decided to send Soha to Ishwari niwas bcoz as she said she doesnt want her daughter to be deprived of any happiness.
In a minute after meeting Suhana, Ishwari's yearning got quenched and she started finding faults in her bringing up. Bcoz it relates to Sonakshi. Instead of enjoying the moment of meeting her grand daughter she was again dukhi.
U know y, bcoz this is Ishwari trait, she wants happiness also to be her way, events, moments doesnt make her happy, its her way that makes her happy. Problem is Ishwari is obsessed with her righteouness.
Sona was the last victim of her "my way" syndrome. Her only issue with Sonakshi was Sona was not her choice, so she made sure that she exits Dev's life and now her new victim will be Soha.
Ishu aunty u r putting ur foot in wrong thing, u will fall on ur face badly.
This is smart Soha not seedhi saadhi Sonakshi and behind her is her spineful mom and not ur spineless son.
