Replying...
Intro. Following the death of his sister Bianca, Nico discards his childhood interests, even burning his Mythomagic cards, which he suddenly views as "useless".He becomes consumed by bitterness, primarily toward Percy Jackson, whom he blames for failing to protect Bianca. This flaw often leads him to refuse help or avoid others even in dangerous situations. Believing he is unwanted by the living and the dead alike, he chooses to live in the Underworld or wander the world alone. He develops an "unhealthy independence," fearing that opening up to others will only lead to more pain. This stage showcases his immense resilience. He survives a solo journey through Tartarus—a feat that nearly breaks his sanity but proves his mental strength is virtually unmatched by any other demigod.
