I always think how funny this scene could’ve been, when he smells the love potion in Slughorn’s classroom, without realising what it was. Not that I think the scene should have been different, but I laugh picturing it, since Harry himself hadn’t realised his own feelings yet.

‘Ginny’s perfume!’ Harry said triumphantly, glad he was able to remember. Hermione stared at him, mouth agape, looking utterly shocked. Her expression then turned to suppressed laughter. Ron looked confused, like he was about to argue, when Slughorn waddled over.

Harry’s mouth fell open, and he felt his ears start to grow hot. He chanced a look at Ron, whose brow was furrowed, looking confused. He looked over at Harry. His expression slowly changed to realisation, followed by shock, and finally glowing red with anger.

‘Right, let’s get started!’ ejaculated Slughorn.
