I dont think Zoro is done this arc till enma is a black blade and that probably involves kaido. Plus both of them are probably waking up cause fainting means jack shit in wano.
especially after seeing other characters which are less important moving doing shit when they should be done for the rest of the raid.
Check Robin - after blackmaria (coudnt even stand on her own, brook had to carry her for 3 chapters)
Check 9 scabban - all had plots going on after kaido (some still fighting 1 vs 1 (stupid ninja fight) / Denjiro is somewhere probably going to hyori. Kinemon after the first defeat encounter Kaido again and he still is playin a role in Onigashima ( a dead man playing a role)
Check the samurai affected by the ice oni
Check Usopp (that took Ulti headbutt and crack his head)
Check Orochi
Check Apoo
Check Marco
Kinemon after the first defeat with kaido, Oda let met Kaido&Kinemon again but Zoro cant right? Clowns
Sure Zoro is done because (I am scarred that he will do some crazy stuff and taking the shine from Luffy) that the only reason they are thinking about that.
