“It—” said Harry, looking everywhere but at Snape, “it was—just a dream I had.”
“A dream?” repeated Snape.
There was a pause during which Harry stared fixedly at a large dead frog suspended in a jar of purple liquid.
“You do know why we are here, don’t you, Potter?” said Snape, in a low, dangerous voice. “You do know why I am giving up my evenings to this tedious job?”
“Yes,” said Harry stiffly.
“Remind me why we are here, Potter.”
“So I can learn Occlumency,” said Harry, now glaring at a dead eel.
“Correct, Potter. And dim though you may be—” Harry looked back at Snape, hating him “—I would have thought that after over two months of lessons you might have made some progress. How many other dreams about the Dark Lord have you had?”
“Just that one,” lied Harry.
“Perhaps,” said Snape, his dark, cold eyes narrowing slightly, “perhaps you actually enjoy having these visions and dreams, Potter. Maybe they make you feel special—important?”
“No, they don’t,” said Harry, his jaw set and his fingers clenched tightly around the handle of his wand.
“That is just as well, Potter,” said Snape coldly, “because you are neither special nor important, and it is not up to you to find out what the Dark Lord is saying to his Death Eaters.”
“No—that’s your job, isn’t it?” Harry shot at him.
He had not meant to say it; it had burst out of him in temper. For a long moment they stared at each other, Harry convinced he had gone too far. But there was a curious, almost satisfied expression on Snape’s face when he answered.
“Yes, Potter,” he said, his eyes glinting. “That is my job. Now, if you are ready, we will start again.”
He raised his wand: “One—two—three—Legilimens!”
A hundred Dementors were swooping towards Harry across the lake in the grounds… he screwed up his face in concentration… they were coming closer… he could see the dark holes beneath their hoods… yet he could also see Snape standing in front of him, his eyes fixed on Harry’s face, muttering under his breath… and somehow, Snape was growing clearer, and the Dementors were growing fainter…
Harry raised his own wand.
“Protego!”
Snape staggered—his wand flew upwards, away from Harry—and suddenly Harry’s mind was teeming with memories that were not his: a hook-nosed man was shouting at a cowering woman, while a small dark-haired boy cried in a corner… a greasy-haired teenager sat alone in a dark bedroom, pointing his wand at the ceiling, shooting down flies… a girl was laughing as a scrawny boy tried to mount a bucking broomstick—“ENOUGH!”
Harry felt as though he had been pushed hard in the chest; he staggered several steps backwards, hit some of the shelves covering Snape’s walls and heard something crack. Snape was shaking slightly, and was very white in the face.
The back of Harry’s robes was damp. One of the jars behind him had broken when he fell against it; the pickled slimy thing within was swirling in its draining potion.
“Reparo,” hissed Snape, and the jar sealed itself at once. “Well, Potter… that was certainly an improvement…” Panting slightly, Snape straightened the Pensieve in which he had again stored some of his thoughts before starting the lesson, almost as though he was checking they were still there. “I don’t remember telling you to use a Shield Charm… but there is no doubt that it was effective…”
Harry did not speak; he felt that to say anything might be dangerous. He was sure he had just broken into Snape’s memories, that he had just seen scenes from Snape’s childhood. It was unnerving to think that the little boy who had been crying as he watched his parents shouting was actually standing in front of him with such loathing in his eyes.
“Let’s try again, shall we?” said Snape.
Harry felt a thrill of dread; he was about to pay for what had just happened, he was sure of it. They moved back into position with the desk between them, Harry feeling he was going to find it much harder to empty his mind this time.
“On the count of three, then,” said Snape, raising his wand once more. “One—two—”
Harry did not have time to gather himself together and attempt to clear his mind before Snape cried, “Legilimens!”
He was hurtling along the corridor towards the Department of Mysteries, past the blank stone walls, past the torches—the plain black door was growing ever larger; he was moving so fast he was going to collide with it, he was feet from it and again he could see that chink of faint blue light—
The door had flown open! He was through it at last, inside a black-walled, black-floored circular room lit with blue-flamed candles, and there were more doors all around him—he needed to go on—but which door ought he to take—?
“POTTER!”
Harry opened his eyes. He was flat on his back again with no memory of having got there; he was also panting as though he really had run the length of the Department of Mysteries corridor, really had sprinted through the black door and found the circular room.
“Explain yourself!” said Snape, who was standing over him, looking furious.
“I… dunno what happened,” said Harry truthfully, standing up. There was a lump on the back of his head from where he had hit the ground and he felt feverish. “I’ve never seen that before. I mean, I told you, I’ve dreamed about the door… but it’s never opened before—”
“You are not working hard enough!”
For some reason, Snape seemed even angrier than he had done two minutes before, when Harry had seen into his teacher’s memories.
“You are lazy and sloppy, Potter, it is small wonder that the Dark Lord—”
“Can you tell me something, sir?” said Harry, firing up again. “Why do you call Voldemort the Dark Lord? I’ve only ever heard Death Eaters call him that.”
Snape opened his mouth in a snarl—and a woman screamed from somewhere outside the room.
Snape’s head jerked upwards; he was gazing at the ceiling.
“What the—?” he muttered.
Harry could hear a muffled commotion coming from what he thought might be the Entrance Hall. Snape looked round at him, frowning.
“Did you see anything unusual on your way down here, Potter?”
Harry shook his head. Somewhere above them, the woman screamed again. Snape strode to his office door, his wand still held at the ready, and swept out of sight. Harry hesitated for a moment, then followed.
The screams were indeed coming from the Entrance Hall; they grew louder as Harry ran towards the stone steps leading up from the dungeons. When he reached the top he found the Entrance Hall packed; students had come flooding out of the Great Hall, where dinner was still in progress, to see what was going on; others had crammed themselves on to the marble staircase. Harry pushed forwards through a knot of tall Slytherins and saw that the onlookers had formed a great ring, some of them looking shocked, others even frightened. Professor McGonagall was directly opposite Harry on the other side of the Hall; she looked as though what she was watching made her feel faintly sick.
Professor Trelawney was standing in the middle of the Entrance Hall with her wand in one hand and an empty sherry bottle in the other, looking utterly mad. Her hair was sticking up on end, her glasses were lopsided so that one eye was magnified more than the other; her innumerable shawls and scarves were trailing haphazardly from her shoulders, giving the impression that she was falling apart at the seams. Two large trunks lay on the floor beside her, one of them upside-down; it looked very much as though it had been thrown down the stairs after her. Professor Trelawney was staring, apparently terrified, at something Harry could not see but which seemed to be standing at the foot of the stairs.
