It wasn’t odd for the Slytherin prefect - Tom Riddle to be out after hours. Tom was always wondering the Hogwarts halls at ungodly hours, doing Merlin knows what, nobody ever stopped and asked.. nor questioned him.

The clock struck midnight and Tom was wondering the halls again, sneaking in and out of passages throughout the castle.. dark thoughts plaguing his mind, images of twisted and deep murderous desire shrouding his being in shadowing malevolent, sin and corruption.
