How I think (hope?) the rest of this goes:
- Apoo calls remaining Numbers to deal with Performance Floor shit, either Chopper or Usopp comes in to deal with them. Maybe Usopp gets a moment where he defeats the 6 Number separately. Chopper takes another Rumble, turns into a bigger monster and fights the last 3. Or maybe either fights all 10.
- Raizo beats Fuku, Drake beats Apoo, Killer beats Hawkins
- Momo saves Onigashima, lands it outside of the capital
- Yamato guards the entrance of Onigashima when she notices Big Mom's crew rolling up since they've been chasing the island from Hakumai. Several strawhats join her. As do several scabbards (Izo, Kawamatsu, Denjiro). As do Drake and Killer possibly. Big fight ensues, gives us reason to finish BMs crew and also explains why some people have been relatively healthy. More of a montage battle than 1v1s. Maybe Yamato vs Smoothie?
- Momo goes to deal with Orochi after Orochi does something drastic, not sure what (I think he's gonna jump off the island before it falls). Gets Ame, does his thing. Maybe involves Hiyori
- Last 4 remaining fights ensue while the above 2 bullets occur.
This would have to involve Onigashima falling in the next 3-5 chapters, otherwise I'm not sure Oda will let the King/Queen fights last that long, but I'm sure the others will fall first (Hawkins, Apoo, Fuku).
