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.
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.
