@Count:
Regardless, I'm having a feeling that Luffy getting at least most of Big Mom's army out of Sweet City is going to leave from for Bege, Germa 66, and/or even Caesar to throw some sort of coup (whether they team up or do separate rebellious acts that coincidentally compliment each other). The timing could never be better, and I can see Judge having grand plans of eventually betraying Big Mom than just being satisfied with her forces helping him take over North Blue. And I don't know, something just seems fishy about how he's so willing to disregard his invitation to the Reverie in favor of a Yonko's help. Along with that backstory of Vito mentioning the comic of the Marine Hero Sora versus Germa 66 (which is DEFINITELY going to get some sort of elaboration sooner or later and probably a Noland or Fishman Island-esque flashback). I can't help but wonder if the Marines/WG get involved during or right after the arc due to their close connection to Germa 66 to take down Big Mom. The only thing that makes me doubt that the Charlottes and Vinsmokes will be at odds soon is that stuff like the bob exploding will take place the day before the wedding. Meaning that the wedding would probably be called off. And I just cannot see Oda succumbing to the trope of having the Straw Hats crash the wedding to save Sanji, along with some type of gangster wedding war. It's too priceless to NOT happen lol.
But those are all just vague feelings I have. And I wonder where Big Mom's other two Sweet Generals are. It would make sense to keep them at the capital if everybody else is trying to kill Luffy.
I agree regarding Vinsmokes. Considering how much pull they seem to have with the WG it seems strange that he would throw it all away for a much less stable ally. Also keep in mind that Judge's ambitions seem to be in north blue which is pretty far away from Big Mom's "area" and is actually in the "marine controlled zone"
considering all the other shady WG-backed organizations I would be surprised if the Vinsmokes are not part of something larger.
