Chitra , it is highly impossible to see change in every person around you so that you can lead a peaceful life. Some people won't change their basic nature come what may. RR and Vicky belong to that type. Iswari also would have remained the same had Sonakshi's heartfelt attempt to remove the Khatri issue from her life not happened. It shook her from the base and wiped off her animosity towards Sonakshi. Destiny favoured and Iswari could see Sonakshi's reality.
@Lakshmi there is no doubt about Dev's magnanimity and generosity...he was epitome of magnanimity pre and post marriage also... he doesn't have to validate it even in the post breakup because sonakshi is well aware of his love and understanding...what went wrong in their relationship was during a critical situation he couldn't reach upto her expectations or in other words she was left alone to fight against all demons...if a similar situation comes again whether Dev would be the pillar of support for sonakshi is highly uncertain...in finance theory we classify people into those who love risk, averse risk and hedge risk. When she married Dev, she was aware that she is marrying someone's CHAND how can he be her SUN...so Sonakshi couldn't averse risk as she let her decisions controlled by her emotions rather than intellect...now she is hedging the risk because she knows entering into Dev's life again means lots of risky propositions...it's not Dev but the inmates of IN have to change...but her short stay has proved that they are in the same spot as she left them 7 years back only change is they have become stronger and powerful...more over now whatever decisions she takes the repercussions will be on many innocent lives like Soha, Golu and her sister Elena. Sonakshi knows her future with Dev will be BLEAK unless some of the residents of IN leave or the permanent residents change their attitude...she is ready to wait...here a feasible outcome for everyone would be what you suggested in your short story...Vicky and his parents leave to Mumbai forever...
