Sona knew there is no one in the house caring for dev. So went there to put some sense in ishwari to take care of her son. Now onwards surely she is going to observe her son.. hope now onwards at least she will see whether he is alive or dead. If she had not gone there ishwari will be in her own dilutional world, Dev never open up and in the house every one are spineless who has no guts to say straight on ishwari house.
Yes sonakshi still fighting and trying to get small ray of hope.
This is what makes me feel Sona is different
I don't know makers will ever show Dev coming to know how much Sona tried to make their relationship. Yday sisters came to know about Dev being angry. . But not Sona came home. According ish bola says everything, why not this big thing.
Krpkb script writer is same person who whote for MB. In MB also the man realising about pain given to female was very poorly written.. so I am doubting we will ever get to see that realisation part.
