In the scene from "The Son of Neptune" by Rick Riordan, a character expresses confusion about a group of beings they encounter, prompting a whisper of surprise. Percy informs him that they are referred to as Canadians, a term used by Annabeth when he previously fought them. This response reflects the lighthearted banter typical among the characters as they navigate their unusual circumstances.

Frank, seemingly offended, emphasizes his own Canadian identity while expressing that he has never encountered such beings before. This interaction highlights the blend of humor and cultural reference in the dialogue, illustrating how the characters grapple with their situations while also poking fun at the unfamiliarity of their environment.
