Y'know, this was long, long, overdue, but I had to comment on Usopp's weapons this chapter. So I noticed that his Kabuto is a different one from the shorter version we've seen up until now (in fact, it looks much more like the version we were familiar with before the skip!). Secondly..... is that a
Piranha Plant that he's using as a weapon?
And..... yeah, currently I'm still betting on my "Luffy vaccine" theory to be the solution towards curing all the victims of Caesar's poison....
