After seeing Luffy's panel
I have a feeling he'll resume the fight next chapter
I don't know, he doesn't seem put because of Kaido's attacks
Rather it just feels like running out of Haki type of white eyes
Even the damage
Not looking too bloody
And even Kaido's dialog about "should have cut your throat, at this point people will continue believing your victory"
As if Kaido knows Luffy will be back
In fact, MAYBE, Luffy ran out of Haki and because Kaido is excited, and he messes with his food as Big Mom says, maybe he is letting Luffy recover his haki back just to continue the excitement
Maybe that's what it feels like to me honestly
