I believe that Oda is intentionally hiding a number of things such as the state of the world, the distribution of forces among pirates and marines, the supernovas ... but global turning points are here and evident through intensely clouded... the purpose is that the state of the world will be a shock to all of us readers be it in terms of the actual straw hat crews abilities and philosophies and the changes elsewhere. A new world, new in all the sense of the word. We are totally ignorant of what lies ahead. One only anchor is the past. It would be absurd for the strawhat to go into the unknown, expect Luffy to be ignorant of all the ramifications involved with the dark century, the death of Fisher Tiger, the queen, the nobles involvement. The nobles have been there again and again. They just popped up and caused misery and death all around them. It seemed that something awful must have happened.
The queen was unable to touch her own people through she can sense people's feeling, know people's heart. Yet we learn that she was able to reach an agreement with the noble. Did she knew something about the noble that we don't know? She must be aware of his feeling, his heart and knew something about the outcome of her involvement with them?
Can we expect the one killing her to be one master of deception? one that even the queen being unable to her his/her heart? a treason?
The issue is that everybody predicted that the queen will die or at least to become a slave. But 625 has proven all of us wrong? How did she secure that grants?
We can expect to start to learn something great next week about the nature of the danger ahead and a tip of the new world from that past turning moment of world story.
