I do fundamentally think at this point, if he recovers, his literal only choice is Brook (strong IF, but I find it fascinating he broke the floor to Brooks floor)
It's either he stays support for a fight that's clearly Robin focused, or he gets his own "weakened" fight. Idk it's a lose lose now.
I do think Jinbe has to be placed somewhere else though, he seems fine. If we are doing the whole new monster trio thing, it would be worth giving him to Jack.
