There was a scuffling and a great thump. Someone else had clambered out of the tunnel, overbalanced slightly, and fallen. He pulled himself up no the nearest chair, looked around through lopsided horn-rimmed glasses, and said, “Am I too late? Has it started? I only just found out, so I—I—”

Percy spluttered into silence. Evidently he had not expected to run into most of his family. There was a long moment of astonishment, broken by Fleur turning to Lupin and saying, in a wildly transparent attempt to break the tension. “So—’ow eez leetle Teddy?”

Lupin blinked at her, startled. The silence between the Weasleys seemed to be solidifying, like ice.

“I—oh yes—he’s fine!” Lupin said loudly. “Yes, Tonks is with him—at her mother’s—”

Percy and the other Weasleys were still staring at one another, frozen.

“Here, I’ve got a picture!” Lupin shouted, pulling a photograph from inside his jacket and showing it to Fleur and Harry, who saw a tiny baby with a tuft of bright turquoise hair, waving fat fists at the camera.

“I was a fool!” Percy roared, so loudly that Lupin nearly dropped his photograph. “I was an idiot, I was a pompous prat, I was a—a—”

“Ministry-loving, family-disowning, power-hungry moron,” said Fred.

Percy swallowed.

“Yes, I was!”

“Well, you can’t say fairer than that,” said Fred, holding his hand out to Percy.

Mrs. Weasley burst into tears. She ran forward, pushed Fred aside, and pulled Percy into a strangling hug, while he patted her on the back, his eyes on his father.

“I’m sorry, Dad,” Percy said.

Mr. Weasley blinked rather rapidly, then he too hurried to hug his son.

“What made you see sense, Perce?” inquired George.

“It’s been coming on for a while,” said Percy, mopping his eyes under his glasses with a corner of his traveling cloak. “But I had to find a way out and it’s not so easy at the Ministry, they’re imprisoning traitors all the time. I managed to make contact with Aberforth and he tipped me off ten minutes ago that Hogwarts was going to make a fight of it, so here I am.”

“Well, we do look to our prefects to take a lead at times such as these,” said George in a good imitation of Percy’s most pompous manner. “Now let’s get upstairs and fight, or all the good Death Eaters’ll be taken.”

“So, you’re my sister in-law now?” said Percy, shaking hands with Fleur as they hurried off toward the staircase with Bill, Fred, and George.

“Ginny!” barked Mrs. Weasley.

Ginny had been attempting, under cover of the reconciliation, to sneak upstairs too.

“Molly, how about this,” said Lupin. “Why doesn’t Ginny stay here, then at least she’ll be on the scene and know what’s going on, but she won’t be in the middle of the fighting?”

“I—”

“That’s a good idea,” said Mr. Weasley firmly, “Ginny, you stay in this room, you hear me?”

Ginny did not seem to like the idea much, but under her father’s unusually stern gaze, she nodded. Mr. and Mrs. Weasley and Lupin headed off to the stairs as well.

“Where’s Ron?” asked Harry, “Where’s Hermione?”

“They must have gone up the Great Hall already,” Mr. Weasley called over his shoulder.

“I didn’t see them pass me,” said Harry.

“They said something about a bathroom,” said Ginny, “not long after you left.”

“A bathroom?”

Harry strode across the room to an open door leading off the Room of Requirement and checked the bathroom beyond. It was empty.

“You’re sure they said bath—?”

But then his scar seared and the Room of Requirement vanished. He was looking through the high wrought-iron gates with winged boats on pillars at either side, looking through the dark grounds toward the castle, which was ablaze with lights. Nagini lay draped over his shoulders. He was possessed of that cold, cruel sense of purpose that preceded murder.

31. THE BATTLE OF HOGWARTS

The enchanted ceiling of the Great Hall was dark and scattered with stars, and below it the four long House tables were lined with disheveled students, some in traveling cloaks, others in dressing gowns. Here and there shone the pearly white figures of the school ghosts. Every eye, living and dead, was fixed upon Professor McGonagall, who was speaking from the raised platform at the top of the Hall. Behind her stood the remaining teaches, including the palomino centaur, Firenze, and the members of the Order of the Phoenix who had arrived to fight.

“…evacuation will be overseen by Mr. Filch and Madame Pomfrey. Prefects, when I give the word, you will organize your House and take your charges in orderly fashion to the evacuation point.

Many of the students looked petrified. However, as Harry skirted the walls, scanning the Gryffindor table for Ron and Hermione, Ernie Macmillan stood up at the Hufflepuff table and shouted; “And what if we want to stay and fight?”

There was a smattering of applause.

“If you are of age, you may stay,” said Professor McGonagall.

“What about our things?” called a girl at the Ravenclaw table. “Our trunks, our owls?”

“We have no time to collect possessions,” said Professor McGonagall. “The important thing is to get you out of here safely.”

“Where’s Professor Snape?” shouted a girl from the Slytherin table.

“He has, to use the common phrase, done a bunk,” replied Professor McGonagall and a great cheer erupted from the Gryffindors, Hufflepuffs, and Ravenclaws.

Harry moved up the Hall alongside the Gryffindor table, still looking for Ron and Hermione. As he passed, faces turned in his direction, and a great deal of whispering broke out in his wake.

“We have already placed protection around the castle,” Professor McGonagall was saying, “but it is unlikely to hold for very long unless we reinforce it. I must ask you, therefore, to move quickly and calmly, and do as your prefects—”

But her final words were drowned as a different voice echoed throughout the Hall. It was high, cold, and clear. There was no telling from where it came. It seemed to issue from the walls themselves. Like the monster it had once commanded, it might have lain dormant there for centuries.

“I know that you are preparing to fight.” There were screams amongst the students, some of whom clutched each other, looking around in terror for the source of the sound. “Your efforts are futile. You cannot fight me. I do not want to kill you. I have great respect for the teachers of Hogwarts. I do not want to spill magical blood.”

There was silence in the Hall now, the kind of silence that presses against the eardrums, that seems too huge to be contained by walls.

“Give me Harry Potter,” said Voldemort’s voice, “and none shall not be harmed. Give me Harry Potter and I shall leave the school untouched. Give me Harry Potter and you will be rewarded.

“You have until midnight.”

The silence swallowed them all again. Every head turned, every eye in the place seemed to have found Harry, to hold him forever in the glare of thousands of invisible beams. Then a figure rose from the Slytherin table and he recognized Pansy Parkinson as she raised a shaking arm and screamed, “But he’s there! Potter’s there. Someone grab him!”

Before Harry could speak, there was a massive movement. The Gryffindors in front of him had risen and stood facing, not Harry, but the Slytherins. Then the Hufflepuffs stood, and almost at the same moment, the Ravenclaws, all of them with their backs to Harry, all of them looking toward Pansy instead, and Harry, awestruck and overwhelmed, saw wands emerging everywhere, pulled from beneath cloaks and from under sleeves.

“Thank you, Miss Parkinson,” said Professor McGonagall in a clipped voice. “You will leave the Hall first with Mr. Filch. If the rest of your House could follow.”

Harry heard the grinding of the benches and then the sound of the Slytherins trooping out on the other side of the Hall.
