“This left Harry, Ron, and Hermione to share a table with Ernie. They chose the one nearest a gold-colored cauldron that was emitting one of the most seductive scents Harry had ever inhaled: Somehow it reminded him simultaneously of treacle tart, the woody smell of a broomstick handle, and something flowery he thought he might have smelled at the Burrow. He found that he was breathing very slowly and deeply and that the potion’s fumes seemed to be filling him up like drink. A great contentment stole over him; he grinned across at Ron, who grinned back lazily.”
“Hang on,” said a voice close by Harry’s left ear and he caught a sudden waft of that flowery smell he had picked up in Slughorn’s dungeon. He looked around and saw that Ginny had joined them.“
Chapter six: The Journey from Platform Nine and Three Quarters
‘Sunshine, daisies, butter mellow, Turn this stupid, fat rat yellow.’ He waved his wand, but nothing happened. Scabbers stayed grey and fast asleep. 'Are you sure that’s a real spell?’ said the girl. 'Well, it’s not very good, is it? I’ve tried a few simple spells just for practice and it’s all worked for me. Nobody in my family’s magic at all, it was ever such a surprise when I got my letter, but I was ever so pleased, of course, I mean, it’s the very best school of witchcraft there is, I’ve heard - I’ve learnt all our set books off by heart, of course, I just hope it will be enough - I’m Hermione Granger, by the way, who are you?’ She said all this very fast. Harry looked at Ron and was relieved to see by his stunned face that he hadn’t learnt all the set books off by heart either. 'I’m Ron Weasley,’ Ron muttered. 'Harry Potter,’ said Harry.
The shouting and the echoes seemed to be driving the troll berserk. It roared again and started towards Ron, who was nearest and had no way to escape. Harry then did something that was both very brave and very stupid: he took a great running jump and managed to fasten his arms around the troll’s neck from behind. The troll couldn’t feel Harry hanging there, but even a troll will notice if you stick a long bit of wood up its nose, and Harry’s wand had still been in his hand when he’d jumped - it had gone straight up one of the troll’s nostrils. Howling with pain, the troll twisted and flailed its club, with Harry clinging on for dear life; any second, the troll was going to rip him off or catch him with a terrible blow with the club. Hermione had sunk to the floor in fright; Ron pulled out his own wand - not knowing what he was going to do he heard himself cry the first spell that came into his head: ‘Wingardium Leviosa!’ The club flew suddenly out of the troll’s hand, rose high, high up into the air, turned slowly over - and dropped, with a sickening crack, on to its owner’s head. The troll swayed on the spot and then fell flat on its face, with a thud that made the whole room tremble.
