Honestly the biggest problem here is that it involves Bonney and kuma separating which genuinely makes no sense to me.
The entire point of this flashback has been about how strong the bond between these two are and the promise that when these two reunite they’ll go off together and travel the world together.
Bonney and Kuma deciding to separate again after losing so many years together goes against a major narrative of this flashback imo
My reasoning here is that Kuma doesn't want Bonney to be involved in a war. Kuma's made it clear he wants to rejoin the Revolutionaries, even as a Shichibukai he was helping them behind the scenes.
If there's anyone Kuma would trust to protect Bonney, it's Luffy/Nika.
Finally, why in the fuck would Kuma trust Dragon to protect his family for a third time??? WHY????????
There's a reason Oda put the "A child is a parent's weakness" line in the chapter; it's to justify Kuma and Bonney separating until the world is freed fromthe WG. If Bonney joined the Revolutionaries, what's stopping the Celestial Dragons from pulling another Ginny? Kuma would have to spend all his time worrying about the same thing happening again.
Bonney needs to be protected from the WG at this point, and who better to protect her than a Yonkou crew? Same thing with Vivi, IMO.
Nico Robin is literally one of the most wanted people in the world due to Pluton, and is MUCH more important than Bonney to the WG, and the Straw Hats have kept Robin very safe after Enies Lobby.
The fact that the Straw Hats were willing to blow up Enies Lobby to save Robin is all the proof Kuma needs that Luffy will take care of his daughter, to me.
Bro if Bonney joins the Revs and then gets kidnapped by Celestial Dragons I will actually toss my computer out the window.
