You slither into the Snake's House common room for personal reasons. You manage to somehow sneak into the corridor leading to the dorms unnoticed by anyone (or at least so you thought), when all of a sudden you get caught by two strong arms and pulled firmly behind a green-silver Serpent's House tapestry and into a secret passage.

You realise it's Regulus who's holding you... He's frowning, as he looks at you with a searching gaze of his green eyes.

"What do you think you're doing?" he asks seriously, eyeing you scrutinously and suspiciously. His tone of voice is cold although laced with a subtle hint of curiosity.
