Gaimon did have a point.
- the grand fleet can't just appear like a genie in a bottle
This entire thing made me ask myself something about this- if Luffy basically dying at Kaido's hands wasn't enough to cause the Grand Fleet to move, then what will?
That's a legitimate question, right? Luffy, in that picture I showed, said he will call for them to support him. He didn't call for them at Wano, so I guess that's the answer for that. It would've made a lot of sense to, though, and honestly it would've been kind of cool if at least a few of them showed up and fought Kaido along with Yamato or something while Luffy was coming back to the fight.
