Marco: I like Oden but Wano Kuni's news don't go across the sea... I never thought that the situation would be like this
Idk what people are complaining about. This does not mean that they didn’t know about Oden’s death or that Kaido was on Wano, this reads to me as Marco not knowing that the situation on Wano currently is as bad as it is with the labor camps, prison camps, etc.
Also, regarding Oden, if they didn’t know, would that really make so little sense? It would imply then that no one knew except for people of Wano, and since news from there is isolated, it wouldn’t have gotten out. Neko and Inu would have left the island, but they were retainers and knew about the 20 year prophecy, so they wouldn’t have gone to seek help regardless because of it. Oden also jumped ship from Whitebeard to Roger, so it’s reasonable if they thought for a time that he jumped with Kaido after he left Roger’s crew.
I’d like it to be more explained, but I doubt it means what everyone is jumping to.
