People have pointed out that Yamato's line about leaving with Luffy being a red herring... but it only took 4 chapters for Oda to drop that Yamato's DF is a guardian spirit of Wano... basically slapping us in the face with the idea of Yamato staying. Doesn't that completely undermine the first line as a red herring? I'm thinking that the whole staying/leaving discussion is a red herring for something bigger.
