Friends Jyoti and I have developed another theory of what will happen now ... Kaju may run to Dev's house where Ameesha may have left the manik outside Dev's door and quietly gone off to the puja, so that she will not be there when Dev has an accident!
Dev starts choking and falling by the effect of the manik and maybe falls down bleeding and unconscious with the locket tight in his hand ...
Meanwhile Kaju will come to his house maybe to ask why he doesn't love her and did all that at the hotel, and may find him in his room uncoscious and bleeding. She will find the locket in his hand and know he still loves her!
The she will find the patra and see that he is going to die.
She will then get an idea "Even if he dies, for one minute at least let him be my husband" and so she will raise his bleeding hand and apply it on her maang as sindoor and thus be married to him while he is unconscious.
Now Dev will not be able to stop her, and his family will come back to find shaadi is fully done already (without Kaju knowing of the curse on her life!)
Plus when Dhruv knows all this too because of the mangni fiasco he cannot fight with Dev - because Kaju did all this on her own proving her love for Dev! And Uncle and Bua also can't say anything! Its is a completed marriage.
So then the story may be that Dev is safe, and gets angry that Kaju has thus risked her life, but happy he is married to her ... and the story may be about Dev trying to save Kaju's life!
For this I hope the upaay will be the arrival of Payal (who then as the first legal wife will die by the curse instead of Kaju!)
