This chapter was both setup and changing of tides.
Both the battles up top and down below are starting go south for the Alliance, while Oda is putting everyone in place for something.
Before that, the beginning of the chapter gives us a glimpse of the Wano citizens. This was a very important inclusion because the citizens haven't been too sympathetic outside of a few named characters and Ebisu town. Getting to see how the Flower Capital folk feel about Kaido and Orochi's rules and seeing how unfortunate they think of it proves even they haven't had it that good. To me, this implies the fight will move to the mainland in some capacity. They want to witness their liberation.
Their wishes contrast and juxtapose effectively with the following page which sees the samurai fight on their behalf being shot and turned to frost demons.
And this is where we get to the setup portion.
Luffy and Co Head Up
First: Luffy, Sanji, and Jinbe are heading up the castle to the top of the dome. They each come with levels. This might be where Sanji and Jinbe get their fights against Calamities as they preach Luffy to head towards Kaido. Basically Dressrosa all over again.
Nami and Usopp's Stand
King has ordered the execution of Momonosuke. All of the F6 received this message, meaning Ulti and P1 got it. They were last seen chasing Nami and Usopp. Upon hearing that the dino siblings are going for Momo, this would logically motivate Nami and Usopp to stand their ground and confront them.
Franky and the Numbers
Franky has already led some of the Numbers away from the plaza. This could mean Franky faces them somewhere outside.
The Plaza
The plaza where Zoro, Drake and co are is now a trap as Queen ordered all the exits to be locked. This means the lionshare of allies are stuck at the mercy of the Plague bullets. The only Strawhats we see there are the aforementioned Zoro, Chopper and Robin. Chopper is there because he can reverse the effects of Queen's plagues. Zoro, and this is the interesting part, is with all the Samurai. And he is with them just as everything is beginning to go wrong. I think this will be the opportunity for Zoro to rally the Samurai in some fashion just like he promised back on Zou. Robin is hard to say because even if she holds the plague infected Samurai down, she is at risk of being infected upon contact. But she is the only Strawhat with a means to fly there, so maybe she can transport some of the characters up to the top of the dome later on.
Brook's Whereabouts
Brook is once again inconspicuously missing. I don't think he's still in the plaza because Oda gave us an update on what each Strawhat is doing during the last few chapters. When Queen said to lock all the exits, that shouldn't apply to Brook since he can enter soul form and pass through. I think Brook might do one of 2 things.
1. Encounter the silhouette that was behind Robin and Jinbe.
2. Find the Poneglyph that's somewhere on Onigashima.
The Scabbards Fall
And finally, the Scabbards. This is now Kaido's fight. While they put up a valiant effort up t'ill now, it's clear Kaido is still too strong for them. It's looking more and more like Luffy will come to the scene just as they have been defeated. Kaido also keeps comparing the Scabbards to Oden and how their sword skills don't compare to his. Obvious implication that Zoro will indeed have an interaction of sorts with Kaido later.
Small note: We haven't seen Kid, Killer, and Law in forever. In fact, most of the WG members aren't close or attempting to go to the top of the dome. Aside from maybe Apoo, I see all the others having reason to face Kaido and being up there. Oda is perhaps planning for them to be there as the final pillar against Kaido and Linlin. Which ties back to the passing of the torch towards the new era. Kaido and Linlin are the last bastions of the bygone age of Roger and Whitebeard, and Wano will signal a complete shift.
he really dont hate King as people think and FUCK KIKUUUUUUUUUUUUUUUUUUUUUUUUUUUUU he was a TRAP Anyway 
Traps in anime are always trash
