Holding out hope this is another partial fake out.
Really don't want to see this arc get derailed by a shitty, tacked on traitor plotline.
This is why I hate Oda's numerology. The dead zones in arcs just so he can have a certain event happen on a certain date/chapter are insufferable for weekly readers. And then people will gaslight you to your face and pretend Oda would NEVER do that. Hehhhhhhhhhhhhhhhhhhhhh.
Having pirates and the Marines fight over the Vegapunks would be really fun. Hell, that's what I wanted in the first place. Now Usopp is a stone-man and Sanji's trying to commit child murder, fuck off, Oda, just give us what we want, rather than this stupid baity bullshit.
