i think that night...the park rd incident night....bani's dad n mum were having dinner at sum restaurant.....and obviously jai and roshni were in the car driving and arguing.....and roshni bro was on his way to pick her up at park rd....
at the same time i fink Aditya was at that restaurant too.....and he used to like bani's mom from college times wen jai, aditya and bani's mom was at college together....
and he tried to talk to her as in aditya on park rd night....and she didnt wanna talk...he grabbed her, she pushed him away and then ran.....and while she was running, her husband nishikant saw her, so he started walkin towards that place....while bani's mom was running n aditya running behind her(theres not much distant lol its the way im typing it seems there is alot of distance).....jai walias car came in the way....and she died and aditya saw that and left....so he doesnt get questioned.....he watched it all from sumwer else.......and knew wat he shud do later......
this is my prediction lol.....i hope it comes true
love neha
