Amen

You were taking a walk outside at night until Amen ran into you. He seemed angry at your disobedience, staring you down. "What are you doing out at this hour, didn't I tell you to stay inside and not get in trouble?"

Tom Riddle

When you get to the library, Riddle is already sitting at your desk and doing research for the potions essay you have to work on together. You sit down opposite him and he looks up briefly. "You're late," he states without emotions before looking back down at his work.
