Another banger of a chapter. Now speculation time! So I'm against the theory that Bonnie is Ginny purely on how when Luffy and friends found her in the ocean, she was in a childs body, the Age Age fruit would be disabled at that point and looking how Ginny looks when she's 13, her size could correspond to having a lot of her mother and would track with the timeline.
Other theory, Kuma didn't seem to be brave enough to respond to Ginny's feelings when she proposed, what if Ginny ended up hitched to Roger? Last flashback point is 14 years, and prior to that is 22, Luffy would have been born in 19, so possible that in that period after joining the Revolutionary army she got closer to Dragon while Kuma was still unable to respond properly. Would also explain why it's Roger the one getting the report of Ginny's abduction and his face.
Now this brings the next big question, is Bonnie Kuma's daughter? Is she Dragon's daughter? Bonnie doesn't seem to have any of the traits of Kuma's race. Also, maybe Ginny was already pregnant with Dragon's second kid when she got abducted (again, 14 years ago, she is born almost a year later). So yeah, this is my expectation, Dragon for whatever reason fails/cannot save her, Kuma comes in, but has to sell his soul to the Goverment in the form of becoming a Shichibukai and participating in the Pacifista program to only possibly be able to save Bonnie.
... well all of that or maybe Bonnie is a clone of Ginny. Not the first one we've seen.
