Thank you
@Lance_Dragonite for your full summery.
There are 2 things that I ll say:
First if Big Mom will face 2 vs 1
The same will happen later with Kaido (so that Oda can potrayed the Kid pirate = to the strawhat)
Now we know for a fact that Zoro has already scarred Kaido but we haven't see Kaido commenting anything about : "waiting a monstrous samurai as Oden" that leave to 2 scenarios:
Someone new will show a feat such as Oden
or Zoro will be back vs Kaido at some point - (Zoro will show that his flying dragon blaze will finally connected to Kaido showing an equal feat as Ryuma)
Now Law&Zoro look like they will not stay on the rooftop so that Oda can show a 1 vs 1 for Luffy for a while.
Interesting is that Law notice that Hackai left insane amount of dmg to Zoro which is fucking expected (it is almost as painfull as in Thriller Bark) but remeber the last one stading there was Zoro (so be prepare for that).
Law notice also how beastly Zoro is which after Killer,Kid and now Law they are putting Zoro @ the top for the supernova.
Last thing, Kaido after (the sumo guy, notice too something extremely important in Zoro) his own aura, which Kaido state is CoC which doesnt surprise me a bit after what Brook mention too.
We ll get a confirmation, after the chapter drop with pictures everything will be much more clear.
By the way, I always said that there is a 1 vs 1 for Luffy but that is not the end result of the fight, Luffy will not end the fight in 1 vs 1.
I am 100% sure.
