To me concerning Yamato, it felt like Oda at the last moment got cold feet and changed his mind about Yamato joining the crew? Which is fine btw.
I've studied a lot of authors that do big time series, and there are times when they are planning on a character doing something, and when they get to that moment, they realize that the character wouldn't do the thing the way it was initially planned.
I really never had a preference with Yamato, as long as Jinbei was in the crew, I don't care who or who doesn't join.
I'm really interested in the story moving forward, the first time since Punk Hazard, that there isn't really a "plan" for the next adventure. We still need to find the location of the final Road Poneglyph. I'm really hoping that it doesn't just happen to be at the next island? LoL.
I'm really wondering if Vivi's status will make the Straw Hats act? And with the new Pacifista's, does this mean that all the Kuma versions are clones of Kuma that have been cyborged up? And does that mean, that there is maybe a conscience in there? It's actually super dark stuff lol.
And I loved Rayleigh coming in like a boss, wish we'd gotten his old/current bounty? But I really love that Oda is staying true to Blackbeard's character, that he's slightly a cowered, it still makes me wonder if Teach is actually a D, or just says that, because he was inspired by someone? Or a story?
Also very happy that Koby did not defeat Boa, like a lot of people thought he would.
