"...I haven't actually read it in years," Hermione admitted, when Harry got back to Hogwarts. "But you're right – I didn't think of it like that."
"What's that?" Neville asked.
"It's this book," Harry explained, holding it up. "It's about a very smart girl who's sort of so smart that she starts being able to do things with her mind – like knock over a glass of water, or float some chalk around."
"...so it's about Hermione, then?" Neville asked. "I knew there were those books about you, Harry, but I only really read that last one with the human you and the dragon you."
"I don't think so," Hermione replied, frowning. "I'd be about the right sort of age, maybe a year or two older, but my childhood was kind of nice. Matilda's childhood is really nasty, her parents don't like her and her headmistress doesn't either."
She shook her head. "I'm starting to wonder if Roald Dahl knew someone who went to Hogwarts, now. It's a lot like accidental magic, but it's enough different that you can say it's not..."
"And maybe George's Marvellous Medicine is about how Fred and George do potions research," Harry suggested.
"I doubt it," Hermione replied tartly. "They haven't blown Gryffindor Tower off the castle yet."
