This chapter's epigraph comes from a famous nursery rhyme: "If you're not careful, the wind will blow you away" . In other words, it's not so much that the harpoon isn't good at catching fish, but that the wind is so strong that the fish can't be caught. The harpoon can only catch fish for a few hours at a time, so you have to use internal force to catch the fish. This means that if you use the internal force, you'll be exposed to the identity of the person who caught the fish, and that's just not good enough for a nursery rhyme. So, you know what, we'll just grab some fish and forget about it. Oh, and we're going to bake some fish for you. You know what's going to happen? We'll find out.
