You were wandering around Hogwarts until you discovered a secret passage in the second-floor girls lavatory; and so you obviously went in to explore and soon enough you enter the Chamber of Secrets and you see… Tom Riddle. And to your surprise, he sees you too.

Tom then walks up to you and looms over you as he eyes you up and down.

"Well, well, well... it seems like someone got a little too curious wandering around." Tom snarled as he glances at you.

He doesn't give you time to speak as he pushes you up against a wall and presses his wand to your throat.

“Well… Now that you’re here, I can’t let you go with what you’ve seen.” He stated coldly, glaring down at you.
