What I feel about the track, as a person who has interest in writing...understanding the technicalities of the plot and conflict in story telling...
They are at a point where they need to tie several things.
1. The importance of the family.
2. The wrong done to Sai.
3. SaiRat and Pakhi in their life.
4. Pakhi's change.
Sai left the family, not willing to trust them. Virat chose his family and let her go. The end result is everyone suffered. Ideally, after an event like 'death', of a loving member, people should change. Thats why I say keeping Pakhi negative is absurd or the family. She would have changed, but she is not strong to accept the reality. She is still holding on to Virat, a man who clearly doesnt love her. She is not able to live alone. Contrast this with Sai, she has everything at hand's reach but still she put her self respect above everythign and chose to stay alone. She chose peace over prosperity. Pakhi has to realize it. If I were to write a story around that...then I will not make her negative again.
Sai will see what family can do when people are in distress. They help each other and overcome the grief. For that to happen, she has to know what they went through when Virat was dying and they themselves suffered her loss. She will understand that they indeed loved her. Suffered her and her son's loss. For that, even though initially they are angry that she didnt inform them about her being alive, they will melt. They have to show the love for Savi as Sai's daughter. Then Sai will herself feel obliged to share the information that Savi is their blood too! Sai has to lose the fear that they will snatch her child away. They should show the growth in the family members as well as some understanding from Sai about family dynamics
Last thing is SaiRat. Are they untouched by Pakhi. This is the biggest test. Going by Virat's love for Sai...what is shown and not what is perceived. He said to ashwini that he cant forget sai ever. That is his status. But If he loved Sai, he could not have married Pakhi. The long story he mentioned cannot be just married for Vinu's adoption. For all the difficulties they have undergone, if he had married Pakhi then whats the point? He married his so called first love, when he got a chance. If he has to be made a hero, he should be shown as someone raising above that opportunity. Otherwise, how will he be worthy of Sai's love. She proved her love by staying loyal to him during separation. Raised his daughter, lived his memories through her. She is answerable for only one question, if she loved him so much why didnt she come back to him? That is the question Virat is asking her. For that they need to understand her fear of losing her child. For Sai to understand Virat, nothing but him being in DUTY mode that has no strings attached should come forward.
Yesterday Pakhi said one dialogue "You will never abandon a person in difficulty". This has to come true with Pakhi. I still believe marrying Pakhi is not Vinu's adoption. There is much more to it.
Also, Sai expressed how much she is hurt to see Pakhi and Virat together. She said she will handle the pain alone. So yeah she will be CN seeing them together, but as a doctor. We all know that she will be pained. But she will get family's support. If they go by KD, Virat might feed Pakhi too!! So be prepared.
