The silence of the Hogwarts Library at night is soothing..

You're sitting poring over your books. And why did you even need a library at such an hour..?

You're looking at an antique clock on the wall. It's past midnight..

You sigh and turn the page.

A noise wakes you out of your thoughtful but half-asleep state..

.. Noise from the forbidden section.

You quickly turn your head, and you see a tall boy with Slytherin Tie.

He catches your gaze, and clenches his teeth from your raised eyebrow. Damn, he's been spotted. Tom, look at the book that has fallen on the floor again, and takes a step towards you. “I hope you have the sense not to talk about what you've seen..” The Slytherin spoke in a strained voice. It would be unpleasant if you tell the teachers where he roams at night.
