THE REVOLUTIONARIES LEFT BALTIGO BEFORE BLACKBEARD’S ATTACK

As it is indicated in the end of the chapter, the revolutionnaries’s headquarters had been destroyed, Sabo and Dragon’s faces are shown in the newspaper. It is highly unlikely that the Revo were utterly defeated, and their base totally annihilated, otherwise all of Dragon and the revo’s hype would be gone to waste.Here is my speculation: Dragon noticed Jesus’s presence, because if he’s really a Wind/Air logia, he would be able to detect the small fluctuation of air in Baltigo, the same as Enel when he can hear voices using electromagnetical waves, or Crocodile who can detect underground rivers with his DF. I think that Dragon successfully summoned all of the revo leaders and came up with a plan to crush the WG , the Reverie is a good opportunity, as well as Doflamingo’s defeat, and left Baltigo to start their offensive, because it’s high time the revo shine, as they have (especially Dragon) done nothing since the beginning of the manga. Oda wanted One Piece to last 5 years so if he introduced Dragon so early in the series, it’s definitively because he had something to do.

My perfect scenario is that the Revo vanished entirely from Baltigo, taking with them Burgress as an hostage. BB arrive and realize there is nothing left, by rage he destroy the island using Black Hole, which is his only island-level destruction technique. Much later, during the Reverie, the kings discuss affairs when suddenly Dragon appear just in front of them, using his Wind powers, and unleash a large scale battle in Mariejoie. It would be the perfect opportunity to present the revo as a real organization, alongside with the Marines and the Yonkou, and hype Dragon.
