Awesome post, I love how you get deep into the symbolism/duality Oda loves to use. There's so many parallels running through this story, because that's what it's all about: inherited Wills! I love Wano, because we're watching the Wills of so many great pirates (Shirohige/Whitebeard, Roger, Oden, Rocks) get carried by those who knew them, and those who didn't.
I'm more convinced of Zoro Kills Kaido than ever, now. Nice Observation Haki, man!
