This separation is going to be a lambi judai for Ronakshi.
First they'll show her recovering from accident and taking the step to be this cold and focused person.
Then her life as this new person
Rohit realising he's done a mistake letting her go and manaofying her
Her melting by Rohit's attempts
Re-union
Pheww! Old wine in a new bottle.
As much as Sonakshi should be this determined and focused, she isn't going to be with rohit, which is not something we wanted. Rohit is going to go from guilt to being ignored to being hurt by Sonakshi, and where he has also been wrong, he truly doesn't deserve this eternal pain! He has been betrayed by family, lied to by his wife, and for the sake of love releases her (not saying that's right) and then goes through pain to win her back as well. Why can't both be left happy!
I'm curious if Rohit will continue to stay in SM after knowing how his family has been bad to him and has killed his married life and hurt the love of his life. I'm also curious to know after reunion if Sonakshi will be agreeable to go back and stay with the sippys in SM. (But considering how they've changed Sumit overnight, and sippys from good to bad, similarly they will be shown to become good again, so)
