Luffy: wait!! Someone is in the water!
Strawhats: there’s no way a person is in there!! Is it a mermaid?!
Sanji: no he’s right!! I can hear the cry of a lady!!
Nami: you hear it from inside the water?! Are you serious?!
Remember when people said that Sanji never actually heard Tashigi's teardrop (and that it was only just a cool line) or that Sanji's CoO doesnt actually allow him to hear from far away. This is actually a long awaited W for the Sanji fandom lol.
