the vansh- ichcha marriage goof-up, the letter ka jhol...was all done by tappu...nani had nothing to do with it....so dont blame her.........her biggest mistake was misguiding tappu when she was kid....nobody can deny that.....
well thats the whole point....shes poisoned tapu's mind...remember when the divorce papers came and tapu was about to sign but nani said no dont give into ichaa...so then tapu made this whole plan about sid trying to kill her....nani has ALWAYS been responsible in some way.
