Three other characters in the novels are romantically interested in Percy, though he remains mostly oblivious. Nico di Angelo's hero worship of Percy turns into an ever-worsening crush on him; at the same time, Nico resents Percy because he believes that Percy had allowed his sister Bianca to die in battle. The second is Calypso, who was banished to the island of Ogygia. The third is Reyna Ramírez-Arellano, who, while is silently attracted to her comrade Jason Grace, finds herself attracted to many of Percy's similar traits.
