I Will Get Much, Much Stronger! Zoro's Pledge to his Captain!

A group of people are gathered to see some kind of freak show. Robin and the revolutionaries question Brook as to why she suddenly changed her mind and decided to come with them to Baltigo.
Usopp is running with Heracles telling him that he needs to lose weight and get much stronger. Zoro meanwhile is begging Mihawk to train him to become a great swordsman.
