I wonder what will draw Marco away from King to allow Zoro to fight him. I also wonder when that fight starts.
The timing seems off right now, especially if Sanji's fight against Queen begins this soon.
Unless Marco decides to leave King to Kawamatsu and Izo and helps Chopper heal Zoro, I'm not too sure how Oda will piece it all together.
If Chopper ends up not getting any assistance from Marco, then I wouldn't want Zoro to get healed too quickly since it kind of makes Hakkai less credible in the end. Though, the problem with this is that we wouldn't actually be getting a full-on fight between Zoro and King the same way we would with Sanji and Queen.
Whatever Oda chooses to do, I hope it turns out good in the end, lol.
