The end of the lesson in sight, Snape strode over to Neville, who was cowering by his cauldron.
“Everyone gather ’round,” said Snape, his black eyes glittering, “and watch what happens to Longbottom’s toad. If he has managed to produce a Shrinking Solution, it will shrink to a tadpole. If, as I don’t doubt, he has done it wrong, his toad is likely to be poisoned.”
The Gryffindors watched fearfully. The Slytherins looked excited. Snape picked up Trevor the toad in his left hand and dipped a small spoon into Neville’s potion, which was now green. He trickled a few drops down Trevor’s throat.
There was a moment of hushed silence, in which Trevor gulped; then there was a small pop, and Trevor the tadpole was wriggling in Snape’s palm.
The Gryffindors burst into applause. Snape, looking sour, pulled a small bottle from the pocket of his robe, poured a few drops on top of Trevor, and he reappeared suddenly, fully grown.
“Five points from Gryffindor,” said Snape, which wiped the smiles from every face. “I told you not to help him, Miss Granger. Class dismissed.”
Harry, Ron, and Hermione climbed the steps to the entrance hall. Harry was still thinking about what Malfoy had said, while Ron was seething about Snape.
“Five points from Gryffindor because the potion was all right! Why didn’t you lie, Hermione? You should’ve said Neville did it all by himself!”
Hermione didn’t answer. Ron looked around.
“Where is she?”
Harry turned too. They were at the top of the steps now, watching the rest of the class pass them, heading for the Great Hall and lunch.
“She was right behind us,” said Ron, frowning.
Malfoy passed them, walking between Crabbe and Goyle. He smirked at Harry and disappeared.
“There she is,” said Harry.
Hermione was panting slightly, hurrying up the stairs; one hand clutched her bag, the other seemed to be tucking something down the front of her robes.
“How did you do that?” said Ron.
“What?” said Hermione, joining them.
“One minute you were right behind us, the next moment, you were back at the bottom of the stairs again.”
“What?” Hermione looked slightly confused. “Oh—I had to go back for something. Oh no—”
