You forgot Charlos? This guy had 13 "wives" and yes, Celestial Dragons throw these away like some broken toys.
Let's hope this is the case but honestly, I very much doubt that Kuma is still the father. I mean, he hasn't even seen Ginny for a while and they also weren't in a relationship the last time they were together.
I read your other posts about the pregnancy delay and although it might sound possible at first, Kuma and Ginny needed to have an intimate relationship at least...
Plus, Oda loves to connect tragic characters against villains like that, e. g. Spandam and Diamante. If Garling is Bonney's father, Kuma might even fight against him. Even if it isn't Garling but another God Knight, this matchup can still happen.
