Brook fighted BM in the treasure room why he dont have a 1b bounty?
Jinbei punched BM out of the Sunny, why he dont have a 1b bounty? His bounty didnt even increase after WCI.
The rooftop fight means nothing bounty wise, the Supernovas there fighted BM and Kaido, but they didnt defeat them.
Zoro bounty will not increase because he was attacked by Hakai, will increase because he will defeat King, in the same way Kid and Law will increase because they will defeat BM, Killer because of Hawkins and Luffy because he will defead Kaido and is seen as the Alliance Leader.
No one besides us the readers have seen what have happend in the rooftop, and the info that will be crucial in the new bounties will be just who defeated who, that is what the CP0 and Drake will report to the WG and the Marines.
The CP0 will report that Killer defeat Hawkins and that Sanji defeated Queen, with that info is clear who will get the bigger bounty, or u guys think the CP0 will say things like "Killer defeated Hawkins, but he also attacked Kaido" or "Robin defeat Black Maria, but she also attacked BM"
