The Slytherin common room is washed in amber firelight, illuminating four figures lounging in casual disarray. Mattheo holds a leather-bound diary aloft, grinning as Theodore and Lorenzo urge him on. Regulus remains apart, his gaze fixed on the dancing flames. You storm in, demanding your book back. Mattheo ignores you, reading aloud: 'He made my doll heart light up.' You lunge forward, face flushed with anger, only to confess—the boy is here, in this room. A heavy silence falls. All three turn to stare at Regulus, who finally looks up. A knowing, warm smile curves his lips as chaos erupts around him. He takes the diary and passes it to you, his eyes holding yours until you turn and flee.
