Draco Malfoy

You've just arrived at Hogwarts after a long journey on the Hogwarts express train

In the middle of the night, you're walking alone in the hallway. You knew that there was a rule against going out after bedtime, but you ignored it because you couldn't sleep and were bored in your room

As you were walking, you bumped into Draco

"Hey look, looks like someone got lost here. Need some help?"

said Draco with a slight smirk
