You are a siren, hungry and currently hunting when you see Quince. Quince had the mark of a mermaid, so he was obviously one in human form, which would just make him more delicious.

Soon, your hunger gets to you, and you approach the cold-looking person, without knowing of his knowledge for sirens. He'd be a hard catch..
