1) Ishwari realizing her insecurities, the consequences of it, and the redemption by which she goes from being the MIL to her DIL to being a mother to the daughter.
2) Dev will learn to be happy by himself and take "right decisions" because they are "right" and not influenced by others. He will start making his own decisions without being blinded by faith and not trying to please everyone.
3) Sonakshi will learn the dilemma that Dev faced when he had to choose between Ishwari and herself. Understand what Dev went through during the marriage phase.
In the current storyline, Dev is still trying to please everyone and is not making his own decisions. He is still dependent on either Sonakshi or Ishwari to take decisions. He needs to stop trying to keep everyone happy at the cost of losing his happiness. Maamaji had once told him that he also has the right to be happy and live like others. The decision of remarriage is Ishwari's. He wants to be with Sonakshi but is not able to because of her decision. Here he is not paying attention to what he wants and his happiness. He still is trying to keep everyone happy and in a way is not taking responsibility of himself and his life. Through this track he will learn to say "No" and make his own decisions in regards to his life.
Similarly Sonakshi has not understood why Dev did the things he did. Although she accepts that she made mistakes, she doesn't fully grasp Dev's dilemma and his vulnerabilities. Right now she is in the exact same place Dev was when he had to choose between Ishwari's happiness and his own. He couldn't make his happiness a priority over his mom's life. Sonakshi is placed at that point right now. She has to review her feelings. She thinks that loving Dev and then marrying him was a mistake. And that she has now moved on. But with the possibility of losing Dev forever, she is now forced to reflect on what she wants in life. She has to start reviewing her actions and retrospect the consequences of her actions. In a way own her true feelings. Something that she has not done for a long time now.
The result of this track will be as Ishwari predicted. That when Dev and Sonakshi come together this time, they will never separate. Both of them will be ready to take responsibility of their relationship and face the consequences together, be it positive or negative. They won't blame each other for any of the negative results. Both will learn to lean on each other as needed and also take lead accordingly. They will learn to live their lives and not the life defined by parents. They will realize their dreams and not let anyone interfere with their lives. 😃
