Interesting chapter.
I notice that for Sanji lore in Cake Island, Oda introduce that very early on, but for Zoro we are exploring Zoro lore at the end of the arc in the midle of the climax, like this arc has more than 100 chapter, and we are getting Zoro lore now. Bolt decision by Oda, meaning he coundt have introduce that early due to much spoiler later on.
Zoro will shine more and more in Wano, we eating good.
