ya, even i think that's what her plan is. remember while she was getting ready for the party, she said ki" main is roop se arjun ko lubhaoongi aur dard doongi" or something like that. and even in today's episode, she said, "uss ghar mein ek hi insaan hai ko meri baat sunega and that's arjun goenka". so i think first woh arjun ko apni mutthi mein karegi so that shefali goes through what bhavri went through and then arjun ko chod degi when arjun would leave everything for her........but by that time hopefull bhoomi will know that arjun ne uske saath koi dhokha nahi kiya tha
