Have you guys noticed that all the characters in Kasam Se have brains except for the main jodi that is Jai and Bani.
To start with:
Aparajith Dev: He very well planned and trapped Jai, first by kidnapping his son, then sending him to jail, and now fooling him as the sanyasi, and now lately the bid.
Rano: Atleast she was suspicious enough that the sanyasi had some other motives in entering the WM.
Ranveer: He called the doctor, to check up Rano.
Dadi: Was suspecious after all the hungama that happened in their house, meaning the noise she heard at night etc...etc...
Aditya: In the bid he had doubt why the guy was biding for such a large amount when the real price was really small.
And down to the two brainless characters Jai and Bani, who never seem to use logic or sense probarly, every one except them are on the right track.
