In "The Ship of the Dead" by Rick Riordan, the character Alex often presents as female, but on certain days identifies as male. This fluidity in gender identity adds complexity to the relationship between Alex and the narrator, who occasionally misuses pronouns. Such moments highlight the playful dynamic they share.
Alex's lighthearted teasing in response to the narrator's mistakes illustrates the strength of their friendship. It reflects an understanding and acceptance of each other's identities, creating a supportive bond that is both fun and affectionate.
