It is going to be a kidnap or an accidental death (since Sibhu was with Kung-Fu action)
If Jiji kidnapped Aditi the story would go dragging for another 3 months. Saloni will come and inform the family that jiji kidnapped Aditi and nobody would believe it and would be difficult for Saloni to prove it and boring for us to watch. I hope this does not happen.
If accidentally Sibhu injures her and presumes that he killed her, he would get scared and run. She will be in the hospital surrounded by family members and she regains conscious and ask for Saloni. Family is surprised and then she will reveal the truth about Sal and Jiji's blackmailing. Some more Rona-Dhona and praising for Saloni and the hunt starts.....
If Aditi died and Saloni informed the family about Aditi's death. I am afraid that Saloni will be blamed for Aditi's death.
If we need a little horror, maybe Aditi will die and her sprit will haunt jiji until she reveals the truth to the family. Just kidding this won't happen.
