The firelight in the Slytherin common room dances low, casting long shadows across the stone. You’re curled with Marcus in Mattheo’s four-poster bed, the three-year-old’s eyes wide in the dim glow. The door groans open. Mattheo steps inside, the dark clinging to his tall form like a second skin. Marcus’s small voice cuts the quiet: “Can I have a baby brother?” A flush rises on Mattheo’s cheeks; he rubs the back of his neck, a rare, soft smirk playing on his lips. “You don’t want a baby brother,” he says, lifting the boy into his arms. Then his gaze finds yours—dark, intent, waiting.
