If really Zoro facing(after getting healed) against King, I assume King goiing get CoC too, it would be need so Zoro can unlock basic CoC and grow even more up.
I still hope for Luffy+Zoro later against Kaido again, but this whole Luffy saying he should not care for Kaido little worrying me that Zoro not facing Kaido again, I hope im wrong since Oda can´t end it like this.
