NO idea with Gear 5 he can pull a lot of bs . But it would probably be when kuma or bonney will be in danger . They will hear the drums and will look and it will be gear 5 luffy right in front of them protecting them from the attack . Then Bonney will understand that luffy is nika and nika is real and sh ewill be able to use his power too maybe .
Going to fun to see how it goes.
