In "The Calling" by Kelley Armstrong, a conversation unfolds between characters about the differences between mermaids and sirens. One character emphasizes that traditionally, mermaids are not depicted as singers while sirens are not known for swimming, hinting at a mix-up in popular culture. This leads to a nostalgic reference to Ariel from "The Little Mermaid," with another character questioning why anyone would have such detailed memories of her name. The interaction highlights the characters’ playful debate over myths and folklore, showcasing their personalities and interests. The mention of Ariel serves as a cultural touchstone, bringing humor to the discussion and indicating that even in casual conversations, the influence of fairy tales can shape perceptions and memories of characters within the fantasy genre.
