coz the real shiv has always done things for Gauri's sake (per say) coz he's never said things to hurt her and he's always been portrayed as an understanding father and husband! of course, he might be a little confused, but all the way dutiful, i would and a very accomplished man! after today's episode, i am definitely sure that's not shiv! he was not drunk, but he was nevertheless really rude to Gauri.. so his only motive is only to get Gauri out of the real shiv's life, according to Nikhila's instructions! nikhila is setting gauri up big time! that's a dirty game she's playing with all five of them. the children, gauri, including shiv (the real one, coz he was supposed to be in banglore right now, and when he'll come back, I suppose the plan is to expose his raaz and gauri will leave him!)
