And while I know some people here "hate" the idea of it, I still think Zoro is a possibility. The last page of this chapter shows Luffy, Law and Kid reacting to the two Yonko, and while I 100% believe Zoro will play a role in finishig Kaido at the end of the arc, it does not imply that he HAS to be there for the entire fight, provided Kaido doesn't just fuck things up the next few chapters with his hybrid. This does not mean Zoro can't return to finish him off later, or at least be involved.
