Snape’s dark eyes bored into Harry’s. Remembering what Snape had said about eye contact being crucial to Legilimency, Harry blinked and looked away.
“How do that man and that room come to be inside your head, Potter?” said Snape.
“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.
