Wasn't it Roshni who killed bani's mom......because in the beginning of Roshni's entry probably the 6th or 5th episode when Jai was suposed to go out with Bani because his masi send them both out but bani didn't go...roshni did and jai forgot his car after some meeting thingy and roshni was all like u can come with me....so when they went in the car roshni almost got into another accident.....then jai says that some peoples habits don't ever change.....so that was a hint that it was roshni driving the car when they went onto to park road.......or i might be wrong but from that episode it sounded as if that roshni caused the accident and that roshni killed bani's mom....please reply and remove this confusion....please....
