Quando Ron encontra Harry no Expresso de Hogwarts em Harry Potter e a Pedra Filosofal, eles têm esta conversa:
“What House are your brothers in?” asked Harry.
“Gryffindor,” said Ron. Gloom seemed to be settling on him again. “Mum and Dad were in it, too. I don’t know what they’ll say if I’m not. I don’t suppose Ravenclaw would be too bad, but imagine if they put me in Slytherin.”
“That’s the House Vol-, I mean, You-Know-Who was in?”
“Yeah,” said Ron. He flopped back into his seat, looking depressed.

Então Ron aparentemente sabe que Voldemort estava na Sonserina. Mas no final de Harry Potter ea Câmara dos Segredos, ficou claro que a verdadeira identidade de Voldemort como o brilhante aluno (sonserino) Tom Riddle é desconhecida para a maioria - nas próprias palavras de Dumbledore:
‘Very few people know that Lord Voldemort was once called Tom Riddle. I taught him myself, fifty years ago, at Hogwarts. He disappeared after leaving the school … travelled far and wide … sank so deeply into the Dark Arts, consorted with the very worst of our kind, underwent so many dangerous, magical transformations, that when he resurfaced as Lord Voldemort, he was barely recognisable. Hardly anyone connected Lord Voldemort with the clever, handsome boy who was once Head Boy here.’
- Harry Potter and the Chamber of Secrets, Chapter 18 (Dobby’s Reward)
Então, como Ron (assim como a maioria dos bruxos) poderia não conhecer a verdadeira identidade de Voldemort e ainda conhecer a casa em que ele estava em Hogwarts?
