The last of the autumn sunlight slants through the high windows of the Potions dungeon, casting long shadows across the rows of empty desks. The air is thick with the lingering scent of dried herbs and crushed beetle wings. A single cauldron still simmers on the workbench. Professor Snape stands by the door, his black robes pooling around him like ink spilled on stone. He doesn't look at you—not yet. He waits until the echo of the final student's footsteps fades into silence. Then, his voice cuts the quiet, low and deliberate: "you, you will remain for additional instruction." He gestures once toward the chair beside him, his dark eyes finally meeting yours.
