Robin isn’t spreading the news just learning it. It’s not going to come out without a means of distribution.
She's a archaeologist my blud. That's what they do.
And know these dreams can’t be completed alone. Luffy made a promise to Laboon too, Frankys ship needs to make it to W7 with him as the shipwright which means the whole crew needs to be there, the complete circumnavigation
Luffy promise to laboon is irrelevant, Nobody really cares about it.
Franky dreams is to circumnavigate doesn't mean their end point has to be W7 only. , moment they complete final journey before or after laugh tale it's over. There's no point making a roundabout befors laugh tale to just log it lol.
And brook dreams can be achieved alone once he's done with all the adventures.
All the dreams doesn't simultaneously have to end with luffy some can do it before it , some at the same time and some after it.
I don't see anyone clearing before luffy though. Chopper probably has a chance here
At the same time is probably only robin who would know history simultaneously as luffy becomes PK. And ussop too
Franky and Nami would complete at the same time.
Sanji is controversial as we don't know what all blue is... maybe travel across it before final journey or maybe after it.
I don't wanna talk about zori dream , it's already a topic of discussion either way.
