"You want Dementors?" Dumbledore looked strangely at Su Er, who stood before him.
"Yes." Su Er nodded. "I originally wanted to use a Boggart transformed into a Dementor as a training target for the students' Patronus Charms, but a Boggart can only imitate its appearance. It doesn't possess the qualities a Dementor should have."
"So I came to ask for your help."
Dumbledore tapped lightly on his desk and thought for a while.
"You should know that there are almost no lone Dementors in Britain," he said.
"You said almost, which means there actually are still Dementors in the country." Su Er seized on that point in Dumbledore's words, smiling like a crafty fox.
"Am I right?"
Su Er had his reasons for being certain Dumbledore could help him obtain Dementors. There were only two days left until the second gathering of the latter half of the school year. Over the past few days, Su Er had used his Patronus to ask quite a few people and received new information from Aberforth.
The Ministry of Magic had two Dementors that had yet to be sent back to Azkaban.
He could actually have brought the Dementors straight in, but Dumbledore was the castle's current master, and bringing Dementors here required his permission. Su Er remembered quite clearly how foul Dumbledore's mood had been when the Dementors had served as guards at Hogwarts Castle during his second year.
Dumbledore saw Su Er's certain expression and the cunning in his eyes clearly, and suddenly smiled.
"It seems you already know where there are Dementors."
"Very well." He raised his fingers and tapped on the desk again. "I can agree to bring over the two Dementors at the Ministry of Magic, but you must keep a close watch on them."
"No problem." Su Er
