imo luffy is knocked out, but probably picking up on bonney emotion, he shown to do this from haki before. also i don't see oda interrupt the flash back till it over, before he make luffy move and fight.
also there zoro who not even there atm, which can deal with kizaru or sanji(once saturn control df is nullified) though imo kizaru not moving shows he not into murdering little girls. as he went easy on bonney, when he tried to knock her out.
imo kuma coming to egghead
he already teleported away from mg after couldn't find bonney here.
so if he does manage to show, or zoro who stop the kill after flashback etc
also luffy just met bonney, but already shown likeing her alot, he only knows so far her dad kuma was turned into mindless cyborg. he has not learned the whole truth
and we are seeing truth in flashback, which is most likely him becoming a slave again so his daughter will be saved(yes i can see luffy get triggered/raged)
for messing with bonney and her dad in such a cruel way.
there other sh on the crew, also baby sit rule seems meh
bonney been dodging wg by herself for two years, even made to mg and was able to get out. the only thing bonney missing is perm home.
also i like vivi, but i remember oda wanted to kill her before he changed his mind.
