Nico struggles to understand the significance of the word "please" in the context of the Underworld, where he believes mercy doesn't exist. For him, the realm is governed by justice, rather than compassion or plea. He emphasizes the finality of death, suggesting that the dead do not have the means to communicate or share secrets, as they are devoid of physical presence and memory.
This reflection on death highlights Nico's perception of the Underworld as a place where the living cannot alter their fates. His stark declaration captures the essence of his character—grounded in reality and shaped by the harsh truths of his existence in a world where the dead are silenced.
