it's not surprising that pia is the one that screams during the prayers.it's kinda hard to tell who is the rapist at this moment but it can br narrowed to to ranjit,shridar orabhi.ranjeet has motive.he want's revenge or on the other hand it could be shridar coz he's getting way out of hand lately.remember the scene where pia was in the bed room and shridar comes from behind turns off the light and tried go get intimate with her and she pushes him away?? could be him.but it does not discount abhi too as he knows her address and could have been the one that tried to molest her the other time.if it's abhi there will be a twist but maybe they put him in the serial so that pia end's up with him.he is not obsessed with pia coz if he was,he would not have backed off when he found out that pia was married.he did admit he had feeling for her but he did not want to pursue it them.but it seems abhi truly cares for her.i hope he is not the one coz they really make a cute pair.i would really love them to be together.hope the writers of saat phere are not party poopers!
