As Fillery meets LeVallon he realizes that the young man is not merely an individual with unusual abilities but someone deeply connected to nature, and LeVallon’s way of thinking and behaving challenges conventional understanding of humanity and introduces entirely new possibilities that profoundly unsettle Fillery’s perspective, while he continues to explore the potential and limits of human consciousness through his observations of LeVallon, and their relationship gradually evolves beyond that of observer and subject into a deeper mutual influence, so that Fillery begins to seek answers to the question of what it truly means to be human on an entirely new level.
