Ron and Hermione were staring at Harry. He had never gone into details about what had happened on the island on the lake: The events that had taken place after he and Dumbledore had returned to Hogwarts had eclipsed it so thoroughly.

“He thought he was back there with you and Grindelwald, I know he did,” said Harry, remembering Dumbledore whispering, pleading.

“He thought he was watching Grindelwald hurting you and Ariana… It was torture to him, if you’d seen him then, you wouldn’t say he was free.”

Aberforth seemed lost in contemplation of his own knotted and veined hands. After a long pause he said. “How can you be sure, Potter, that my brother wasn’t more interested in the greater good than in you? How can you be sure you aren’t dispensable, just like my little sister?”

A shard of ice seemed to pierce Harry’s heart.

“I don’t believe it. Dumbledore loved Harry,” said Hermione.

“Why didn’t he tell him to hide, then?” shot back Aberforth. “Why didn’t he say to him, ‘Take care of yourself, here’s how to survive’?”

“Because,” said Harry before Hermione could answer, “sometimes you’ve got to think about more than your own safety! Sometimes you’ve got to think about the greater good! This is war!”

“You’re seventeen, boy!”

“I’m of age, and I’m going to keep fighting even if you’ve given up!”

“Who says I’ve given up?”

“The Order of the Phoenix is finished,” Harry repeated, “You-Know-Who’s won, it’s over, and anyone who’s pretending different’s kidding themselves.”

“I don’t say I like it, but it’s the truth!”

“No, it isn’t,” said Harry. “Your brother knew how to finish You-Know-Who and he passed the knowledge on to me. I’m going to keep going until I succeed—or I die. Don’t think I don’t know how this might end. I’ve known it for years.”

He waited for Aberforth to jeer or to argue, but he did not. He merely moved.

“We need to get into Hogwarts,” said Harry again. “If you can’t help us, we’ll wait till daybreak, leave you in peace, and try to find a way in ourselves. If you can help us—well, now would be a great time to mention it.”

Aberforth remained fixed in his chair, gazing at Harry with the eye, that were so extraordinarily like his brother’s. At last he cleared his throat, got to his feet, walked around the little table, and approached the portrait of Ariana.

“You know what to do,” he said.

She smiled, turned, and walked away, not as people in portraits usually did, one of the sides of their frames, but along what seemed to be a long tunnel painted behind her. They watched her slight figure retreating until finally she was swallowed by the darkness.

“Er—what—?” began Ron.

“There’s only one way in now,” said Aberforth. “You must know they’ve got all the old secret passageways covered at both ends, Dementors all around the boundary walls, regular patrols inside the school from what my sources tell me. The place has never been so heavily guarded. How you expect to do anything once you get inside it, with Snape in charge and the Carrows as his deputies… well, that’s your lookout, isn’t it? You say you’re prepared to die.”

“But what…?” said Hermione, frowning at Ariana’s picture.

A tiny white dot reappeared at the end of the painted tunnel, and now Ariana was walking back toward them, growing bigger and bigger as she came. But there was somebody else with her now, someone taller than she was, who was limping along, looking excited. His hair was longer than Harry had ever seen. He appeared and torn. Larger and larger the two figures grew, until only their heads and shoulders filled the portrait. Then the whole thing swang forward on the wall like a little door, and the entrance to a real tunnel was revealed. And our of it, his hair overgrown, his face cut, his robes ripped, clambered the real Neville Longbottom, who gave a roar of delight, leapt down from the mantelpiece and yelled.

“I knew you’d come! I knew it, Harry!”

“Neville—what the—how—?”

But Neville had spotted Ron and Hermione, and with yells of delight was hugging them too. The longer Harry looked at Neville, the worse he appeared: One of his eyes was swollen yellow and purple, there were gouge marks on his face, and his general air of unkemptness suggested that he had been living enough. Nevertheless, his battered visage shone with happiness as he let go of Hermione and said again, “I knew you’d come! Kept telling Seamus it was a matter of time!”

“Neville, what’s happened to you?”

“What? This?” Neville dismissed his injuries with a shake of the head. “This is nothing, Seamus is worse. You’ll see. Shall we get going then? Oh,” he turned to Aberforth, “Ab, there might be a couple more people on the way.”

“Couple more?” repeated Aberforth ominously. “What d’you mean, a couple more, Longbottom? There’s a curfew and a Camwaulding Charm on the whole village!”

“I know, that’s why they’ll be Apparating directly into the bar,” said Neville. “Just send them down the passage when they get here, will you? Thanks a lot.”

Neville held out his hand to Hermione and helped her to climb up onto the mantelpiece and into the tunnel; Ron followed, then Neville. Harry addressed Aberforth.

“I don’t know how to thank you. You’ve saved our lives twice.”

“Look after ’em, then,” said Aberforth gruffly. “I might not be able to save ’em a third time.”

Harry clambered up onto the mantelpiece and through the hole behind Ariana’s portrait. There were smooth stone steps on the other side: It looked as though the passageway had been there for years. Brass lamps hung from the walls and the earthy floor was worn and smooth; as they walked, their shadows rippled, fanlike, across the wall.

“How long’s this been here?” Ron asked as they set off. “It isn’t on the Marauder’s Map, is it, Harry? I thought there were only seven passages in and out of school?”

“They sealed off all of those before the start of the year,” said Neville. “There’s no chance of getting through any of them now, not with the curses over the entrances and Death Eaters and Dementors waiting at the exits.” He started walking backward, beaming, drinking them in. “Never mind that stuff… Is it true? Did you break into Gringotts? Did you escape on a dragon? It’s everywhere, everyone’s talking about it, Terry Boot got beaten up by Carrow for yelling about it in the Great Hall at dinner!”

“Yeah, it’s true,” said Harry.

Neville laughed gleefully.

“What did you do with the dragon?”

“Released it into the wild,” said Ron. “Hermione was all for keeping it as a pet—”

“Don’t exaggerate, Ron—”

“But what have you been doing? People have been saying you’ve just been on the run, Harry, but I don’t think so. I think you’ve been up to something.”

“You’re right,” said Harry, “but tell us about Hogwarts, Neville, we haven’t heard anything.”

“It’s been… Well, it’s not really like Hogwarts anymore,” said Neville, the smile fading from his face as he spoke. “Do you know about the Carrows?”

“Those two Death Eaters who teach here?”

“They do more than teach,” said Neville. “They’re in charge of all discipline. They like punishment, the Carrows.”

“Like Umbridge?”

“Nah, they make her look tame. The other teachers are all supposed to refer us to the Carrows if we do anything wrong. They don’t, though, if they can avoid it. You can tell they all hate them as much as we do.”

“Amycus, the bloke, he teaches what used to be Defense Against the Dark Arts, except now it’s just the Dark Arts. We’re supposed to practice the Cruciatus Curse on people who’ve earned detentions—”

“What?”

Harry, Ron, and Hermione’s united voices echoed up and down the passage.

“Yeah,” said Neville. “That’s how I got this one,” he pointed at a particularly deep gash in his cheek, “I refused to do it. Some people are into it, though; Crabbe and Goyle love it. First time they’ve ever been top in anything, I expect.”
