Chapter 892: Acknowledging a Strong Enemy.
Peros doesn't know if he should destroy the cake or leave it alone since if he destroys it Big Mom will kill him, but he thinks Bege poisoned it. If Big Mom dies, then the kingdom is doomed, and if she doesn't get cake she'll doom the kingdom, so it's sort of "damned if you do, damned if you don't."
Meanwhile Bege promises Sanji they won't do anything to the cake, but afterward they're free to do whatever they want to Big Mom, and Sanji agrees to that since his mission was only to make and deliver the cake. Brook lied to Sanji about Pedro dying for some reason...Nami was about to tell him, because he asked about Carrot and Pedro, but Brook said they're both resting in the next room. Peros and the others go after Bege. He tells Smoothie (14), Citron (15), Cinnamon (16) to go after them while he and the other ship go after Bege. Jinbe says Big Mom's forces have them completely surrounded so they've acknowledged how strong the Straw Hats are.
They've still got three hours till getting to Cacao Island but they have no idea when Luffy will show up. Sanji says there's only one plan they can go with then. Meanwhile Oven is telling everyone on the island to break their mirrors. So there's only one way for Luffy to escape if he tries to, where they'll get him.
Now to the fight. Luffy won't stay down and Katakuri realizes if the fight drags on his observation haki will become as good as his.
So he's trying to finish this quickly.
He uses his trident to thrust upon Luffy. His eyes go white. Flampe looks on laughing at Luffy.
