Great grandmaster chapter!!
3 thing about Zoro here:
First he got trained pretty well by Mihawk, all his attitude about playing around with people that are inferior to him is pretty clearly.
X-Drake and Apoo are no match to Zoro. The moment he get serious they both done (one is out, the other is shocked).
Queen realize that his game is broken the moment Zoro destroyed his weapon.
Second Oda is clearly portraying Zoro to be with Luffy the key to win this war. With so many actors present in the room (such brook,chopper,samurai,x-Drake and even Marco) he is the one to get the cure. Everyone is aware of him including the second strongest beast pirate King.
Last point, I really like the moment of reflection that Zoro got here. He wasn't carrying about anything around him but just that arm falling from the sky. It give me the same vibe as when Zoro use the breath of all thing.
Brook mentioning possible CoC for Zoro is mesleading in this case, still Oda clearly want this plot to move foward for Zoro which I belive make totally sense for him. Luffy CoC, Kid CoC, and last Zoro CoC main people facing the strongest Pirate.
I dont care about all the sanji plot line cuz is not interesting at all.
