If it's the case Oda never intended for Yamato to have a trans-coded narrative, he sure is writing a pretty clear one on accident.
In 1024 there is a clear distinction between Yamato referring to himself as a guy and wanting to be Oden and here in 1025 when Yamato is younger he's referred to as a princess and in the present as the son of Kaido.
In a general sense, I think this chapter illustrates why I think Wano is a considerable improvement over a bunch of the post-ts OP stuff.
To me it feels like a much more organic story where events lead into one another instead of the story giving us a list of events.
This expresses itself In some smaller ways and some larger ways.
To me the bigger examples were Luffy's first loss to Kaido, the under-cover section of the story leading into the Onigashima raid and all of the individual fights in these recent chapters.
As much as the Oden flashback didn't make me care as much as I think it should've, what the present story does with the characters influenced by Oden is good in my eyes.
Many of the side characters still feel pretty forgettable and sections are still pretty scattered, but I feel a much stronger cohesion at play with everything: themes, plot, setting and character.
In this chapter, this has everything to do with Momo to me. There was this point of making Momo older, but turns out this seems to make his power much more unstable and in turn interferes with the fighting below. Even if there are elements I don't care for, there is a much stronger sense of continuity to everything and I think that final two-page spread is a really good example of that, too because it feels like that imagery could only happen in these specific circumstances with these specific motivations.
I feel like Dressrosa and Whole Cake particularly weren't just scattered in terms of presentation of events, they were scatterbrained in general.
Another example of cohesion to me from the earlier story is that I didn't care as strongly about Zoro's and Sanji's flashbacks as others, but I can see how they shaped them.
These specific key events in Wano I listed have felt like they got build up on all levels, not just the most simple plot level. Again, not perfect, but 100% an improvement in my eyes.
I dont know if Oda wrote it on purpose, but i think the whole thing with Momo sacrificing his childhood in order to save Wano is an interesting contrast with Oden. Momo in a way is the complete opposite of Oden, and he is meant to attone for Odens mistakes.
Oden grew up in Wano dreaming of becoming a pirate despite being fated to be Shogun. Momo grew up among pirates and dreamed about being shogun.
Odens childish antics doomed Wano, but Momo sacrificed his own childhood and youth in order to save it.
These things seem pretty obvious when you think about it yet Oda has kept it fairly subtle and refrained from blatantly spelling it out.
