Well the new chapter was awesome, Can't wait till next week. Now we know why Zoro was the first to get to Sabbody, lol. Also I noticed that Chopper said something along the lines of , " Yea, there are more marines left because I still hear many voices." Perhaps Chopper has Haki of the mantra type. Or he just heard a loud rumbling of marines yelling; Guess we will see in later chapters.
