The new promo definitely tells a story. Divya talks of the final meeting of Raj and Divya when it happened 10 years back and she says she remembers every minute of it, wonders whether Raj remembers this. Now she says the direction she has decided to take, will he wait for her?
Definitely she is going to try to sort out things n Raj's life and bring sanity back and help him live his life and try to make him accept Sarita.
Regarding what should Divya do? Divya has not been given a special responsibility to sort out everybody's life. She did not do things which were wrong because of which she needs to correct the situation. All three nvolved are adults with ability to think and be responsible for their actions. Divya can offer help but the condition put n by Sarita is not fair. My POV.
