But a mermaid has no tears, and therefore she suffers so much more. Marceline has been shunned her whole life. She can't live with her mother in the sea, and her dad was killed when Marceline was a young girl. She lives with her grandparents, but they don't like the idea of a half-mermaid being their granddaughter. Hogwarts is the only place that has truly felt like home, despite her huge secret that only her closest friends are aware of. But as a certain Weasley twin begins to take notice of her, and her best friend Cedric becomes a Hogwarts champion, it is becoming harder to remain the anonymous Hufflepuff she has so often been.
