Moody was looking very intently at Neville, this time with both eyes.
“Your name’s Longbottom?” he said, his magical eye swooping down to check the register again.
Neville nodded nervously, but Moody made no further inquiries. Turning back to the class at large, he reached into the jar for the next spider and placed it upon the desktop, where it remained motionless, apparently too scared to move.
“The Cruciatus Curse,” said Moody. “Needs to be a bit bigger for you to get the idea,” he said, pointing his wand at the spider. “Engorgio!”
The spider swelled. It was now larger than a tarantula. Abandoning all pretense, Ron pushed his chair backward, as far away from Moody’s desk as possible.
Moody raised his wand again, pointed it at the spider, and muttered, “Crucio!”
At once, the spider’s legs bent in upon its body; it rolled over and began to twitch horribly, rocking from side to side. No sound came from it, but Harry was sure that if it could have given voice, it would have been screaming. Moody did not remove his wand, and the spider started to shudder and jerk more violently—
“Stop it!” Hermione said shrilly.
Harry looked around at her. She was looking, not at the spider, but at Neville, and Harry, following her gaze, saw that Neville’s hands were clenched upon the desk in front of him, his knuckles white, his eyes wide and horrified.
Moody raised his wand. The spider’s legs relaxed, but it continued to twitch.
“Reducio,” Moody muttered, and the spider shrank back to its proper size. He put it back into the jar.
“Pain,” said Moody softly. “You don’t need thumbscrews or knives to torture someone if you can perform the Cruciatus Curse… That one was very popular once too.
“Right… anyone know any others?”
Harry looked around. From the looks on everyone’s faces, he guessed they were all wondering what was going to happen to the last spider. Hermione’s hand shook slightly as, for the third time, she raised it into the air.
“Yes?” said Moody, looking at her.
“Avada Kedavra,” Hermione whispered.
Several people looked uneasily around at her, including Ron.
“Ah,” said Moody, another slight smile twisting his lopsided mouth. “Yes, the last and worst. Avada Kedavra… the Killing Curse.”
He put his hand into the glass jar, and almost as though it knew what was coming, the third spider scuttled frantically around the bottom of the jar, trying to evade Moody’s fingers, but he trapped it, and placed it upon the desktop. It started to scuttle frantically across the wooden surface.
Moody raised his wand, and Harry felt a sudden thrill of foreboding.
“Avada Kedavra!” Moody roared.
There was a flash of blinding green light and a rushing sound, as though a vast, invisible something was soaring through the air—instantaneously the spider rolled over onto its back, unmarked, but unmistakably dead. Several of the students stifled cries; Ron had thrown himself backward and almost toppled off his seat as the spider skidded toward him.
