I think Dumbledore might have hoped I would be able to exercise some

I think Dumbledore might have hoped I would be able to exercise some control over my best friends,’ said Lupin. ‘I need scarcely say that I failed dismally.’

Harry's mood suddenly lifted. His father had not been a prefect either. All at once the party seemed much more enjoyable; he loaded up his plate, feeling doubly fond of everyone in the room.

Ron was rhapsodising about his new broom to anybody who would listen.

‘...nought to seventy in ten seconds, not bad, is it? When you think the Comet Two Ninety's only nought to sixty and that's with a decent tailwind according to Which Broomstick?’

Hermione was talking very earnestly to Lupin about her view of elf rights.

‘I mean, it's the same kind of nonsense as werewolf segregation, isn't it? It all stems from this horrible thing wizards have of thinking they're superior to other creatures....’

Mrs. Weasley and Bill were having their usual argument about Bill's hair.

‘...getting really out of hand, and you're so good-looking, it would look much better shorter, wouldn't it, Harry?’

‘Oh—I dunno—’ said Harry, slightly alarmed at being asked his opinion; he slid away from them in the direction of Fred and George, who were huddled in a corner with Mundungus.

Mundungus stopped talking when he saw Harry, but Fred winked and beckoned Harry closer.

‘It's OK,’ he told Mundungus, ‘we can trust Harry, he's our financial backer.’

‘Look what Dung's got us,’ said George, holding out his hand to Harry. It was full of what looked like shrivelled black pods. A faint rattling noise was coming from them, even though they were completely stationary.

‘Venomous Tentacula seeds,’ said George. ‘We need them for the Skiving Snackboxes but they're a Class C Non-Tradeable Substance so we've been having a bit of trouble getting hold of them.’

‘Ten Galleons the lot, then, Dung?’ said Fred.

‘Wiv all the trouble I went to to get ‘em?’ said Mundungus, his saggy, bloodshot eyes stretching even wider. ‘I'm sorry, lads, but I'm not taking a Knut under twenty.’

‘Dung likes his little joke,’ Fred said to Harry.

‘Yeah, his best one so far has been six Sickles for a bag of Knarl quills,’ said George.

‘Be careful,’ Harry warned them quietly.

‘What?’ said Fred. ‘Mum's busy cooing over Prefect Ron, we're okay.’

‘But Moody could have his eye on you,’ Harry pointed out.

Mundungus looked nervously over his shoulder.

‘Good point, that,’ he grunted. ‘All right, lads, ten it is, if you'll take ‘em quick.’

‘Cheers, Harry!’ said Fred delightedly, when Mundungus had emptied his pockets into the twins’ outstretched hands and scuttled off towards the food. ‘We'd better get these upstairs....’

Harry watched them go, feeling slightly uneasy. It had just occurred to him that Mr. and Mrs. Weasley would want to know how Fred and George were financing their joke shop business when, as was inevitable, they finally found out about it. Giving the twins his Triwizard winnings had seemed a simple thing to do at the time, but what if it led to another family row and a Percy-like estrangement? Would Mrs. Weasley still feel that Harry was as good as her son if she found out he had made it possible for Fred and George to start a career she thought quite unsuitable?

Standing where the twins had left him, with nothing but a guilty weight in the pit of his stomach for company, Harry caught the sound of his own name. Kingsley Shacklebolt's deep voice was audible even over the surrounding chatter.

‘...why Dumbledore didn't make Potter a prefect?’ said Kingsley.

‘He'll have had his reasons,’ replied Lupin.
