Master helmsmen Jinbe
It wasn't always clear to me what Jinbe's official role would be on the Strawhat's crew was, but he will be the helmsmen. The Strawhat's never had an official helmsmen, with Nami, Usopp and Chopper all taking the role. A helmsmen is the person that steers the ship. Jinbe is unsurprisingly capable in this regard being a fishman with experience on the seas. Jinbe has been shown in the anime as being able to steer a ship out of the way of cannon fire. In this chapter, Jinbe manages to use these skills to save the Strawhat's from death. He use the "green room," which is described as "a short lived pocket made inside the crest of a wave."
Luffy in the Mirror-World
Luffy's is notified by Nami that they have survived and smashed all the mirrors. Communicating through a mirror shard, Nami informs him that they will be meeting Sanji at Cacao Island in about ten hours. Katakuri attacks Luffy, who swallows the shard of glass. He informs Nami that they need to hurry, Katakuri reveals a trident made of mochi. He mocks Luffy suggesting that he knows what his last words are going to be. Luffy responds with those words, saying "he will not die here." The real question regarding this part of the arc is what is Luffy going to do that can defeat Katakuri. It is the tendency of many shonen manga that the main character will ALWAYS find the strength to win. However, One piece at least occasionally allows Luffy and others to be defeated. It seems implausible that Luffy will "win" this fight, but he will likely escape somehow.
