This is basically what TB prob one of the best arcs ever IMO brought to the OP world. So basically discuss the new facts and what we have learned from TB.
We had a new shickibaukai in Gecko Moria. The conculsion of the Ace v blackbeard fight. A new crew memember in Brooke. The names of the 2 unknown Yonkou Kaidou and Empress handcock. The signfigance of the paper Ace gave to luffy. Kuma's power and we know he has some type of connection to Dragon.
Thats all i can remember off the top of my head more info would be nice.
