I have a feeling the moment with Yamato not joining that's talked about is a cliffhanger and not an actual confirmation of anything
Like it's gonna end on Luffy saying "no" or something then get clarified the next chapter. Oda does this a lot.
:zorothink:
Also if Yamato does not join but Carrot appears as a stowaway again then Oda might experience some real hellfire rage from the fandom lmao
