Why would Zoro suddenly go from fighting Kaido and Big Mom on the roof to suddenly fighting King, some people are acting like Zoro is going to leave the roof so he can fight King.
Zoro: "Hey sorry guys but I have to leave, I need to go fight King right now."
Luffy: "No problem, see you later Zoro."
Kaido: "Worororo try to take it easy on him."
