As per CV's i guess...the scene was attacker has to shot from far n from somewhere top ...n Sahir has to run n save her n the goli was suppose to be targeted at Sahir's heart ..

now the place where the scene was shooted ..wahan where Arzoo stood uske piche terrace type ki koi place nahi thi 😆 or else some 1 has to shoot from inside the outhouse 😕 khidki khol k may be...🤔

but the shot came from back as he was totally covered from front ...
nextly the superrr Sahir jump...

agar woh aise bahar se run kartey hue aata so they would not have this impact of him running from far 😕...
so for there positions n angle of the shooter...it looked like that... but the bullet was shot from back n got stuck in front ...🤔
PS: even i dint know wad did i just said 😆
