Final answer:
Percy Jackson initially sees Mr. Brunner as a caring teacher who believes in his potential. His perception changes when he learns that Mr. Brunner is Chiron, which enhances his importance in Percy's life.
Step-by-step explanation:
Percy Jackson's views of Mr. Brunner undergo a significant change throughout the course of the story. Initially, Percy sees Mr. Brunner as a strict but caring teacher, someone who believes in Percy's potential despite his academic struggles and apparent ADHD and dyslexia. Mr. Brunner's support and the personal attention he gives Percy set him apart from other teachers. However, as the narrative unfolds and Percy's true heritage and the world of Greek mythology are revealed, Percy's perception of Mr. Brunner changes dramatically. He learns that Mr. Brunner is actually the centaur Chiron, trainer of heroes, and that his interest in Percy is part of a larger, more complex narrative tied to Percy's own identity as a demigod. This revelation transforms Mr. Brunner from merely a supportive educator into a pivotal figure in Percy's life and the mythical world he's becoming a part of.
