“A bad idea, Professor Lockhart,” said Snape, gliding over like a large and malevolent bat. “Longbottom causes devastation with the simplest spells. We’ll be sending what’s left of Finch-Fletchley up to the hospital wing in a matchbox.” Neville’s round, pink face went pinker. “How about Malfoy and Potter?” said Snape with a twisted smile.
“Excellent idea!” said Lockhart, gesturing Harry and Malfoy into the middle of the hall as the crowd backed away to give them room.
“Now, Harry,” said Lockhart. “When Draco points his wand at you, you do this.”
He raised his own wand, attempted a complicated sort of wiggling action, and dropped it. Snape smirked as Lockhart quickly picked it up, saying, “Whoops—my wand is a little overexcited—”
Snape moved closer to Malfoy, bent down, and whispered something in his ear. Malfoy smirked, too. Harry looked up nervously at Lockhart and said, “Professor, could you show me that blocking thing again?”
“Scared?” muttered Malfoy, so that Lockhart couldn’t hear him.
“You wish,” said Harry out of the corner of his mouth.
Lockhart cuffed Harry merrily on the shoulder. “Just do what I did, Harry!”
“What, drop my wand?”
But Lockhart wasn’t listening.
“Three—two—one—go!” he shouted.
Malfoy raised his wand quickly and bellowed, “Serpensortia!”
The end of his wand exploded. Harry watched, aghast, as a long black snake shot out of it, fell heavily onto the floor between them, and raised itself, ready to strike. There were screams as the crowd backed swiftly away, clearing the floor.
“Don’t move, Potter,” said Snape lazily, clearly enjoying the sight of Harry standing motionless, eye to eye with the angry snake. “I’ll get rid of it…”
“Allow me!” shouted Lockhart. He brandished his wand at the snake and there was a loud bang; the snake, instead of vanishing, flew ten feet into the air and fell back to the floor with a loud smack. Enraged, hissing furiously, it slithered straight toward Justin Finch-Fletchley and raised itself again, fangs exposed, poised to strike.
Harry wasn’t sure what made him do it. He wasn’t even aware of deciding to do it. All he knew was that his legs were carrying him forward as though he was on casters and that he had shouted stupidly at the snake, “Leave him alone!” And miraculously—inexplicably—the snake slumped to the floor, docile as a thick, black garden hose, its eyes now on Harry. Harry felt the fear drain out of him. He knew the snake wouldn’t attack anyone now, though how he knew it, he couldn’t have explained.
He looked up at Justin, grinning, expecting to see Justin looking relieved, or puzzled, or even grateful—but certainly not angry and scared.
“What do you think you’re playing at?” he shouted, and before Harry could say anything, Justin had turned and stormed out of the hall.
Snape stepped forward, waved his wand, and the snake vanished in a small puff of black smoke. Snape, too, was looking at Harry in an unexpected way: It was a shrewd and calculating look, and Harry didn’t like it. He was also dimly aware of an ominous muttering all around the walls. Then he felt a tugging on the back of his robes.
“Come on,” said Ron’s voice in his ear. “Move—come on—”
Ron steered him out of the hall, Hermione hurrying alongside them. As they went through the doors, the people on either side drew away as though they were frightened of catching something. Harry didn’t have a clue what was going on, and neither Ron nor Hermione explained anything until they had dragged him all the way up to the empty Gryffindor common room. Then Ron pushed Harry into an armchair and said, “You’re a Parselmouth. Why didn’t you tell us?”
“I’m a what?” said Harry.
“A Parselmouth!” said Ron. “You can talk to snakes!”
“I know,” said Harry. “I mean, that’s only the second time I’ve ever done it. I accidentally set a boa constrictor on my cousin Dudley at the zoo once—long story—but it was telling me it had never seen Brazil and I sort of set it free without meaning to that was before I knew I was a wizard—”
“A boa constrictor told you it had never seen Brazil?” Ron repeated faintly.
“So?” said Harry. “I bet loads of people here can do it.”
“Oh, no they can’t,” said Ron. “It’s not a very common gift. Harry, this is bad.”
“What’s bad?” said Harry, starting to feel quite angry. “What’s wrong with everyone? Listen, if I hadn’t told that snake not to attack Justin—”
“Oh, that’s what you said to it?”
“What d’you mean? You were there—you heard me—”
“I heard you speaking Parseltongue,” said Ron. “Snake language. You could have been saying anything—no wonder Justin panicked, you sounded like you were egging the snake on or something—it was creepy, you know—”
Harry gaped at him.
“I spoke a different language? But—I didn’t realize—how can I speak a language without knowing I can speak it?”
Ron shook his head. Both he and Hermione were looking as though someone had died. Harry couldn’t see what was so terrible.
“D’you want to tell me what’s wrong with stopping a massive snake biting off Justin’s head?” he said. “What does it matter how I did it as long as Justin doesn’t have to join the Headless Hunt?”
“It matters,” said Hermione, speaking at last in a hushed voice, “because being able to talk to snakes was what Salazar Slytherin was famous for. That’s why the symbol of Slytherin House is a serpent.”
Harry’s mouth fell open.
“Exactly,” said Ron. “And now the whole school’s going to think you’re his great great great great grandson or something—”
“But I’m not,” said Harry, with a panic he couldn’t quite explain.
“You’ll find that hard to prove,” said Hermione. “He lived about a thousand years ago; for all we know, you could be.”
Harry lay awake for hours that night. Through a gap in the curtains around his four-poster he watched snow starting to drift past the tower window and wondered…
Could he be a descendant of Salazar Slytherin? He didn’t know anything about his father’s family, after all. The Dursleys had always forbidden questions about his wizarding relatives.
Quietly, Harry tried to say something in Parseltongue. The words wouldn’t come. It seemed he had to be face to face with a snake to do it.
But I’m in Gryffindor, Harry thought. The Sorting Hat wouldn’t have put me in here if I had Slytherin blood…
Ah, said a nasty little voice in his brain, but the Sorting Hat wanted to put you in Slytherin, don’t you remember?
Harry turned over. He’d see Justin the next day in Herbology and he’d explain that he’d been calling the snake off, not egging it on, which (he thought angrily, pummeling his pillow) any fool should have realized.
By next morning, however, the snow that had begun in the night had turned into a blizzard so thick that the last Herbology lesson of the term was canceled: Professor Sprout wanted to fit socks and scarves on the Mandrakes, a tricky operation she would entrust to no one else, now that it was so important for the Mandrakes to grow quickly and revive Mrs. Norris and Colin Creevey.
Harry fretted about this next to the fire in the Gryffindor common room, while Ron and Hermione used their time off to play a game of wizard chess.
“For heaven’s sake, Harry,” said Hermione, exasperated, as one of Ron’s bishops wrestled her knight off his horse and dragged him off the board. “Go and find Justin if it’s so important to you.”
So Harry got up and left through the portrait hole, wondering where Justin might be.
The castle was darker than it usually was in daytime because of the thick, swirling gray snow at every window. Shivering, Harry walked past classrooms where lessons were taking place, catching snatches of what was happening within. Professor McGonagall was shouting at someone who, by the sound of it, had turned his friend into a badger. Resisting the urge to take a look, Harry walked on by, thinking that Justin might be using his free time to catch up on some work, and deciding to check the library first.
