“
Patronuses can change, though, can’t they?” said Ron. “Tonks’s changed, didn’t it?”
“Yeah, but if Dumbledore was alive, why wouldn’t he show himself? Why wouldn’t he just hand us the sword?”
“Search me,” said Ron. “Same reason he didn’t give it to you while he was alive? Same reason he left you an old Snitch and Hermione a book of kids’ stories?”
“Which is what?” asked Harry, turning to look Ron full in the face, desperate for the answer.
“I dunno,” said Ron. “Sometimes I’ve thought, when I’ve been a bit hacked off, he was having a laugh or—or he just wanted to make it more difficult. But I don’t think so, not anymore. He knew what he was doing when he gave me the Deluminator, didn’t he? He—well,” Ron’s ears turned bright red and he became engrossed in a tuft of grass at his feet, which he prodded with his toe, “he must’ve known I’d run out on you.”
“No,” Harry corrected him. “He must’ve known you’d always want to come back.
