Props till Kai som kom dit först.
Harry bekräftar säkert Ron och Hermione i Harry Potter och Phoenix-ordningen som han gav Fred och George guldet.
(Kontext: Det här är strax efter Fred och Georges flykt efter posten)
'It'll be my fault Fred and George left, you wait,' said Ron darkly. 'She'll say I should've stopped them leaving, I should've grabbed the ends of their brooms and hung on or something ... yeah, it'll be all my fault.'
'Yeah, but that's another thing, how did they get premises?' ... 'It's a bit dodgy, isn't it? They'll need loads of Galleons to afford the rent on a place in Diagon Alley. She'll want to know what they've been up to, to get their hands on that sort of gold.'
'Well, yes, that occurred to me, too,' said Hermione, ... 'I've been wondering whether Mundungus has persuaded them to sell stolen goods or something awful.'
'He hasn't,' said Harry curtly.
'How do you know?' said Ron and Hermione together.
'Because -' Harry hesitated, but the moment to confess finally seemed to have come. There was no good to be gained in keeping silent if it meant anyone suspected that Fred and George were criminals. 'Because they got the gold from me. I gave them my Triwizard winnings last June.'
But this is excellent!' said Ron, looking thrilled. 'It's all your fault, Harry - Mum can't blame me at all! Can I tell her?'
'Yeah, I suppose you'd better,' said Harry dully, ''specialy if she thinks they're receiving stolen cauldrons or something.'

Om Fred och George visste att Harry hade berättat Ron och Hermione så sägs det inte. Inte heller är det sagt vad deras officiella linje var. Det bekräftas inte heller om Ron berättade för Mrs Weasley eller inte.
