Charlie is a young boy who loves to play with his train wagon and listens to the music the train makes while on the railroad path. His father wants him to be a pilot one day but he prefers now not to even think about what he would like to be. His teacher is a lovely female and loves quiet-silent times at reading time with her pupils. Charlie likes to read the story "A happy Lemon tree" because it teaches him how it grows and when he finishes the story, he goes rapid to the playground to play with his peers.
I would say Anagnorisis. This means when a character makes a critical discovery, in this case he finds out he was sleeping with his mom and killed his father. It also means a change in what a person stood for. He stood for finding who was the killer, and cursed him, only to find out its him.
