as for gauri she will stay and will save her marriage ..the picture falling and how she caught it means a lot..
i think she has bravely faced all the humiliation shiv has thrown at her and she has not break but still as the promo said "nafrat ko pyar se jeetne ki khoshish ki"kaash jeet jaye gauri ka vishwas"..yeah i think this time too she will save this relationship how much shiv will hate her..
devika will not succeed this time and i have the feeling anupam or mahen will come back now..may be shilpa also will make her entry..
