Instância 1:
“So we’ve just got to try on the hat!” Ron whispered to Harry. “I’ll kill Fred, he was going on about wrestling a troll.”

Instância 2:
Provavelmente Ron estava nervoso, afinal ele tinha cinco irmãos que foram a Hogwarts, ele definitivamente ficaria nervoso. Conhecendo Fred e George, aqueles caras teriam pensado que era divertido assustar Ron.“I’d worked that much out for myself, funnily enough. What happens if you break it, then?”

He went mental,” said Ron, with a reminiscent gleam in his eyes. “Only time I’ve ever seen Dad as angry as Mum, Fred reckons his left buttock has never been the same since.”
