To start off, this chapter shed some light on how Hiyori escaped the destruction of Oren Castle twenty years ago, assuming this woman is telling the truth. I actually hope this woman is being truthful and not another Pudding. Anyway, she still need to explain how she faked her death at the palace.
On another note, the captured Heart Pirates are in the same place with the arrested rebels. If Law is going to save his crew, then perhaps he could also save the rebels.
I guess when push comes to shove, Hyogoro isn't so helpless after all. It's nice to see Luffy utilizing his Kenbunshoku Haki very well. Hopefully Luffy can learn that advanced technique of Busoshoku Haki soon. Though this may help Luffy harm Kaido, I still think it would be beneficial for him to learn Awakening as well. In any case, Luffy gets stronger through trial by fire.
