See, that seems like much more outlandish speculation to me than Luffy having something in common with Joy Boy…Oda’s been pretty gung ho about not including the main character’s mother in the story, and while I would see her inclusion as a much bigger twist than he’s provided as of late, for her to come out of nowhere would make this arc feel even more bloated AND take more focus away from the important things we’re already getting offpaneled.
