Yamato: Let's call Luffy and the others, they are better than this guy
Momonosuke: No, we cannot always rely on them, we have to fight our own fights
Also Yamato: Why can't I fight him (Greenbull)?!
Momonosuke: You mustn't! Don't you dare strike him!
The straw hats right after Aramaki retreated: Sitting, eating, drinking, having fun.
Kurwa: They surely were on high alert but as soon as Greenbull retreated, quickly grabbed food and booze and made it look like a party.
