I think this will happen. Pia will divorce Pushkar. Pushkar will take up drinking. Bani will spend time with him comforting him. Jai will be getting jealous. So, Jai will get close to Pia. Pia will get pregnant because of Jai and Bani will leave Jai for ever and go with Pushkar.
Though it is not nice. But could very much happen
