So this volume just made Zoro confronting Orochi far more likely and plausible than him doing anything to or confronting Kaido in any way.
Zoro’s master, Koushiro, was revealed to be the son of Shimatsuki Kozaburo (swordsmith), the same family as Yasuie, who Orochi killed. When Orochi was younger, he was a servant of the same family, just like Onimaru was, who Zoro clashed against to get Shusui back.
Even without that, Zoro dealing with Orochi at some point was always far more realistic than him doing anything against Kaido, but fanboys...
