These are just my views.😊
We will know more on Monday and I don't know why but I think we will hear Shanky only tell Pankhuri that Adi is responsible but we will not hear the full story yet we will see Shanki telling her but I think there will be music in the background.
Looking at the Precap and how emotional Pankhuri got it appears that Shanky tells her that Adi is responsible and also the spoilers seems to imply that as well, but I wonder if Adi really is responsible.
In the flashbacks Kaira is still a kid and I think Adi is older than her and she looks like she might be around 6 or 7. If he would have done it would he not have realized and said something when Kaira mentioned that her grandfather killed her grandmother, that's why I think it could it be that Adi was at the wrong place at the wrong time and Shanky and Nanaji thought it was Adi. We will know more Monday if the whole story is told.
After Pankhuri and Adi made up after the caretaker incident I thought they decided not to keep anything from each other so maybe that is what the battle is between her and Avantika. Rubel is going to blackmail Avantika and Pankhuri finds out and wants to tell Adi the truth. Avantika being a mother wants to protect her child from any pain and hurt and not reveal it to him that's why I think she will agree to whatever Rubel is blackmailing her for. If Adi was told right away then I think he would be able to show that it was not him and they want to show some drama so the CV's will not show the truth right away.
Another reason I think that Adi is not responsible is because whenever Sheila, Rubel or Latika plan something it starts off promising but eventually it fails(Preeti's miscarriage, getting the Haritka and Paya out of the house and Revealing Pankhuri as the caretaker are some I can remember) and from the spoilers it looks like they plan to use this information to blackmail and hurt the family. I'm curious to see what Anuj's reaction will be to all this.
I also think that Adi being the lead of the show I don't think he will be shown as one, but before that is revealed everyone will think it is him. I think it is someone else and I think it might end up being either Kaira or Rubel, I would like it to be Rubel but I think it will end up being Kaira.
These are just my speculations and after Monday they could be completely wrong.😆
