Harry Potter, the son of his dear friends, stuck his head through the doorway. "Evening, professor. Do you have a minute?"
He gave the boy an encouraging smile. "Of course, Harry. What can I do for you?"
Harry entered the room and closed the door behind him before speaking. "I was hoping you could teach me to fight off Dementors."
Remus had a sinking feeling in his stomach. "Are you sure that's a good idea? Dementors shouldn't hurt you as long as you stay away. I don't want you learning to defend yourself only to go out and provoke them."
The boy stayed quiet for a second. "Ah... I take it you've heard, then?"
"How could I not? It was all the staff talked about last week." Remus slammed his palm on the desk in frustration. "You approached the Dementors on a dare, and kept going until you passed out! Do you even understand how foolish that was?"
"I knew it was a stupid idea, of course," Harry said, crossing his arms. "I'm not stupid."
Remus rubbed his temples. "Then why—"
"I didn't want the bloody Slytherins calling me a coward."
He gaped at the unrepentant boy, then sighed. "I suppose I better teach you before you get yourself killed."
Harry grinned. "Brilliant!"
"Now, don't get too far ahead of yourself," Remus said, raising a hand. "First off, how badly are you affected by their aura? There is a mental technique that staves off the despair for a time, but actually driving a Dementor away requires advanced magic I'm not sure any third-year is capable of."
"I can handle them at a distance, but if I get close..." Harry had a far-away look in his eyes. "I can't think straight, and I hear a female voice in my head, repeating the same sentence over and over."
"What... what does the voice say?" Remus held his breath. The boy's worst memory, his own personal hell had to be—
"Kyon-kun, denwa," Harry said hollowly. "I thought I was back in that endless summer. I don't want to hear it ever again."
Lupin closed his eyes and pinched the bridge of his nose. There was something very odd about this boy.
