Fred e George disseram a alguém onde conseguiram o dinheiro?

Adereços a Kai que chegou primeiro.

Harry certamente confirma para Ron e Hermione em Harry Potter e a Ordem da Fênix que ele deu a Fred e George o ouro.

(Contexto: Isso é logo depois da fuga de Fred e George após o pântano)

'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.'

Se Fred e Jorge sabiam que Harry havia dito a Ron e Hermione isso não é dito. Nem é dito qual era a sua linha oficial. Também não está confirmado se Ron disse ou não à Sra. Weasley.

No começo de A Ordem da Fênix , Harry supõe que a Sra. Weasley ainda não sabe, e teme o que aconteceria se ela descobrisse:

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 Percylike 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? (OP9)

Também os gêmeos Weasley dizem a Mundungus Fletcher quando eles pegam as sementes Venomous Tentacula no capítulo “The Woes of Mrs. Weasley,” que Harry é o seu financiador:

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

”It’s okay,” he told Mundungus, “we can trust Harry, he’s our financial backer.”
