actually if durga and Bani are the same person then her marriage to AD isnt Valid ..UNLESS they have a Fake mariage for MIL sake .the Kasam will definitely be about Bani marrying AD but probably we may be shown that she does so as Durga yet Bani marries JW again secretly -- Hence we think AD-DDG are married yet Bani and JW are and have to be together secretly and not openly hence what RK said that JB will be together yet not together!/!?!?!?!?!??!
This is the scenario I came up with especially with sasuma in bed sick and Bani hovering over her.........
Nina
hasnt RK always said that JB will be togather and not so togather ..its nuthing New that JB saath hokar bhi alag rahenge
