Big Moms comment about Robin is fucking ominous. There are hints in this story about Robin going missing or leaving the crew again (against her will). Back in Zou, Inu told her that people will come after her because how close they are to One Piece. Come this chapter Big Mom is now interested in her. She's still missing her "6th person" chapter number, like Chopper.
Frankly, im even concerned that this might carry over beyond Wano at this point, at least with Big Mom and Rocks. Maybe Kaido goes down, for sure, it should happen, but what if Big Mom doesn't and they take Robin?
