Mr. de Milo was Percy Jackson's English teacher while he was in seventh grade at Meriwether College Prep.
Percy Jackson and the Olympians[]

Percy Jackson, his former student
Mr. de Milo instructs the class to read The Lord of the Flies, setting up a final exam for the students in which they all went into the "break yard" for a period with no adult supervision, which would mimic the scenarios in the book. This leads to many wedgie contests led by the school bully, Matt Sloan, and games of full-contact basketball. After the adults returned, all the students were given passing grades as he felt they understood the book perfectly.
