So with Catarina Devon copying Saturn's face, capturing Koby/Garp, and Lafitte monitoring the RA's blockade of Mariegeois it seems to me like Blackbeard has an interest in going there for some purpose, maybe to negotiate for Hachinosu to be recognized as its own kingdom? That guy always has something going on.

And Barto returns with the Thousand Luffy right???

edit: Just noticed Nami appears to be in a Lego looking room at the end. That's not Elbaf then, despite the costume change.
