as for anu kapoor. i do not think it mattered in the end. he was a high ranking official who could have made up false evidence and got the case closed. in the end, there were no enemies of PC who would have raised an objection! as for naseer... she saw him in the bathroom and noticed a wound on his back. she realized that the wound was from the night when she had hit him on the back of the guy who was trying to kill her.
