Riku, Cobra and Fujitora met. I wonder how much will the World Government be torn apart after the Lev Ely. I mean, I think Dragon knows about Im. That's why he said he was declaring a war against the celestial dragons. I would be surprised if he did not know about Im. I imagine Dragon wants to expose the Empty throne and get other countries to ally with him.
Bonney went to save Kuma, I like it. It was heartbreaking seeing Kuma like that. I hope we get more about Bonney and her history with the government. It could merely be what they did to Kuma, or she could have been used for her devil fruit. Seeing Kuma smile is probably the highlight of the chapter. I like how the revolutionaries and the government are being set up for their final confrontation at the end of the series.
As suspected, the Government will attempt to re-enact the Void Century and that will be the great final war. Without further information I can only assume that: Luffy and Blackbeard are to be killed. Shirahoshi should be captured or killed if resistance is encountered, while Vivi should be put under investigation/keeping an eye on her.
I am assuming that Im is the national treasure that Doffy was talking about. He/She could very well be Uranus, the ancient weapon. I would not be surprised if Im can transform into a "celestial dragon". Could be related to the dragons on Wano, their hate for them, and even their isolation from the World Government to begin with. We finally met the final obstacle for the revolutionaries during the final war. These next few chapters are bound to give us many more surprises.
