It was the first DADA lesson for the Third Years, and everyone was excited, especially four Gryffindor's: Hermione Granger, Percy Jackson, Harry Potter, and Ron Weasley. Well, actually, only Hermione was excited. Harry was nervous, Percy was brooding, and Ron… Well, Ron was hungry, as usual. But Ron's hunger problems are not the point of this story, something far more exciting is.
Anyway, the four of them were walking towards the classroom, the other three leading Percy away from walls, other students, and the occasional flying object. Percy always brooded for the first week or so, and they had grown used to this routine. Finally, they arrived and after a short lesson on dealing with Peeves, the class officially started.
After Neville, Parvati, and Seamus had had their turns with the boggart, it was Percy's turn. He stepped up, as distracted as usual in the first week of school. The hand trapped in a mousetrap transformed with a CRACK, into a fat middle aged man with three oily hairs combed across his scalp, holding a beer bottle in one hand, and poker chips in his other. The class could practically smell his awful scent. But they were too busy gaping at Percy to notice his smell (well not really, you couldn't ignore a smell that bad, but they were trying). Percy had taken a step back, with a terrified look on his face. A terrified look! Percy Jackson was scared of this man, who didn't look much older than Arthur Weasley!
The class waited with bated breath to see what would happen. What did happen was not what they were expecting. The man leered over Percy, who suddenly looked eight years younger.
"Get me my beer, boy. And you got any cash? A boy in this household should be expected to pull his own weight," he snapped. Five seconds later, he spoke again. "No beer? Well then…" and he raised up a hand, and Percy flinched. Then Percy looked up.
"Y-you're not real. You're dead. Y-you k-killed h-her. And then Dad a-and Artemis killed you. You're not real," he said again, this time stronger. "RIDDIKULUS!" Percy shouted. The man transformed into a younger woman with curly brown hair, sparkling blue eyes, and a warm smile, with another CRACK. Percy took one look at her, and ran out of the classroom, tears streaming down his face.
"Percy!" Hermione yelled, but he didn't come back. The lesson finished without further incident, but no one saw Percy anywhere.
