So, what was the narrative purpose of this? I don't mean about Jinbore showing that he's super honorable as always, but what did Oda gain with writing him out from the plot for a while?
I figured something relevant would happen to him there, but so far there's no indication of this. And he didn't swoop in to help SHs for that to be the grand purpose of his return.
What do you think it was, did Oda just have nowhere to fit him in the story? Would a Fishman not be able to hide in Wano etc.?
