Most of the chapter was pointless, we don't need to spend so many pages on goodbyes. So Kaidou is not a human, interesting. Law basically wants the marines to come down on Dfla with everything they have. The guy is a known human traffic king pin and who knows what other dirt the Marines have on him, and on top of that Kaidou would aim for his ass too.
Maybe Law is planning on using Dfla to weaken Kaidou allowing his alliance to take him down ?
Anyway, meh chapter overall due to the pages wasted on goodbyes.
