He thought Hiyori was going to lol, and he thought it was going to be slow to remove him from the performance floor. He jumped on the Chrono bandwagon, which was hilarious to me considering Chrono just wanted to shit on Zoro.
All I've said about it was the possibility that either Chopper or Marco heal Zoro quickly via some broken power or medicine. Turns out it was the minks helping Chopper and Zoro lol.
