I am curious as to where Egghead is going at this point. Assuming Kuma did go to Mariejois, that removes a pretty significant portion of what the arc can achieve here (as it now delays Bonnie's main plotline if anything since Kuma cant be "saved" here).
But it still calls into question Kizaru's purpose as well, since it seems he still will likely be the arc villain at least for preventing Vegapunk from being taken. Im sure we'll at least get a signficant flashback for Kuma/Bonney to explain what happened.
But also, now you have this pretty hefty connection to Elbaf (Kid's scene, plus Vegapunk's history with the island now), and Beehive (Law running into BB, BB kidnapping both Pudding and Koby, Helmeppo being in G14 and wanting to save Koby, now Garp preparing to do so himself).
Considering Law took the shortest route and Kid took the middle, it would suggest we are going to Elbaf, then Beehive after that. But Im curious how each arc actually ends up being developed with Egghead in mind. Then, how this leads to the "endgame" at Laugh Tale and/or Marineford/Mariejois. You still have a slew of related characters and factions (too many to count at this point).
I still think Egghead is a ~30-40 chapter arc with Kizaru and several VAs being the antagonists, but im very curious how that leads to Elbafs plot and Beehives (and potentially other things in between)
