Pants on Fire
Blaise sits alone in the dormitory and stares blankly out the window until Mrs. Delaney shows his father inside, when his stone-cold gaze shifts to the middle-aged man in the doorway.
Behind his father, he can see Harry's wrist in Mrs. Delaney's hand as she drags the boy away from the room.
Johan Zabini smiles hesitantly at the stranger in his son's body, and says he's come to take Blaise home. Blaise doesn't argue: he just stares until his father can't stand still any more, and strides across the dormitory and grasps his son's small hands in his own.
'Was that Harry Potter?' he asks quietly. 'Are you two friends?'
Blaise answers that he doesn't have friends, so his father doesn't extend an invitation for Harry to come and live with them, too.
Harry's laughter is bordering on hysterical when Johan Zabini takes Blaise away. Inside, he can't stop crying.
