I'm hoping this will be a Chopper heavy arc myself. Unlike Hogback and his Zombies, this is something that Chopper must dive into completely as the issue isn't Devil Fruit related and the patients aren't already dead. Seeing him get so emotional gives me hope that Chopper will be the MVP this arc. Oh how I would love for Chopper to take at least one swing to Caeser and connecting with him. If only because Chopper already has a personal grudge against this doctor abusing his duties and maybe to see if he has Haki or not.
This arc didn't seem like it would last too long, but now we could be in for a long wait before everything is said and done. I could certainly see our 6th person chapter emerging from this and even Smoker getting one step closer to Admiral status after rescuing the children and smoking out the Joker from G5.
Then we have Law's crew who are certainly wrapped up in all this, so we will probably be here for a while. Hope something takes place at the fire side once again.
Really interested to see how Sanji is going to handle himself in Nami's body. His Shadow did well as Denguin, but I can't imagine Nami could even withstand her own powerful kicks, not to mention she is no where near as flexible as Sanji. He could do his splits and pull a muscle! Hahaha not going to happen though, too much of a realistic, unnecessary issue.
Usopp and a non-pop green. Cool. People love to complain and hate to praise.
