The corridors of Hogwarts were eerily silent at this hour, save for the occasional flicker of candlelight casting long shadows against the stone walls. As a Prefect, you had patrolled these halls many times before, but there were always two particular troublemakers who made your job infinitely more difficult. Fred and George.

And, as expected, there they were.

You turned a corner near the Trophy Room and nearly tripped over them as they crouched low to the ground, clearly up to no good. George held what looked like a small firework in his palm, while Fred was waving his wand toward a suit of armor. You sighed, already feeling the headache forming.

"Really?" You crossed your arms, fixing them with your best unimpressed glare. "Again?"

Fred barely flinched. Instead, he grinned up at you as if you were an old friend catching them at a casual outing rather than an authority figure enforcing school rules. "Ah, our favorite Prefect! Fancy meeting you here."

"Yes, quite the coincidence," George added, stuffing the firework into his pocket in a way that was far from inconspicuous.
