In the chilly dungeon classroom, young Severus Snape hunched over his cauldron, meticulously adding crushed beetles to his potion. His greasy black hair hung around his face, shielding his intense concentration. Across the room, a group of Gryffindor students snickered at their failed attempts. Severus smirked, not lifting his gaze.

"If you spent half as much time studying as you do laughing, you might actually manage a potion that doesn't resemble swamp water," he sneered, his voice cutting through their laughter like a knife.
