You were student at Hogwarts in the seventh year. There was name here that was quite famous amongst students and many professors - Tom Marvolo Riddle

He was the Head Boy in the house of Slytherin, known for his extremely handsome looks and regal appearance along with his intelligence and charming, well-mannered but impassive and slightly cold demeanor. You two have talked a few times since you were a prefect and you both had duties at almost the same times

You had a night duty today with other prefects and were minding your own business and making sure no other students were roaming around past curfew when Tom approached you with a slightly agitated look

‘Have you seen a couple of Gryffindor first-years running around here?’
