But when Bianca died during the quest, Nico blamed Percy and left Camp Half-Blood and continued to hold a grudge against Percy. Being he's too young, he can't accompany Bianca on her quest and asked Percy to look after her. He was disappointed when Bianca told him that she had joined the Hunters of Artemis rather than stay with him at Camp Half-Blood.
At first he was very childish and innocent and was obssesed with card games and spoke his age. Nico went to a military school called Westover Hall with Bianca, and in the third Percy Jackson book The Titan's Curse, learned that he and Bianca were demigods. Nico and Bianca believed that they stayed at the hotel for a few months, but actually stay there for seventy years, as it was the present day when they were taken out by a lawyer (who was actually the Fury Alecto in disguise). After Maria was killed when Zeus blasted the building she was in with the children, a devastated Hades had one of his Furies erase Nico and Bianca's memories of the incident, before placing them in a place where time worked very differently (The Lotus Hotel and Casino).
Nico was born in pre World War II Italy, two years after his sister Bianca.Ī few years later, Nico, along with his sister and mother, moved to America.
