I do love that Brook's big plan was just to scare the enemy into running away. It kinda reminds me of Han Solo chasing Storm Troopers in Star Wars. And in both cases the bad guys realize that they don't have to be scared.
I'm really wondering what's going to happen with Komurasaki. She was so hyped up and got a ton of focus that I doubt this is the last we'll see of her. And her connection to Kyoshiro adds to both of their mysteries.
From this chapter I'm getting the sense that Orochi is the kind of dude that relies on the raw power of his devil fruit and that he might not be especially skilled with it.
I'm just hoping that we don't get a redemption arc for Big Mom. Oda could pull it off, but I like her as a crazy old pirate lord.
