The Slytherin common room glows underwater-green, the fire in the grate casting long shadows across stone walls. A lone figure hunches in a worn armchair, greasy black hair falling over his face as he pretends to study a potions textbook. His fingers trace the annotation in the margins—his own handwriting—but his dark eyes are unfocused, lost in a thousand bitter scenarios. The fire pops. He doesn't flinch. Then the portrait swings open, and you step into the dim light. His breath catches. He looks up, and for a moment his mask of indifference wavers. 'you,' he says, his voice barely above a whisper, and the book slips from his hands onto the floor.
