Why would Kuma be linked to all of those? lol
And we already know Kuma founded Revos alongside Dragon
And we already know Vegapunk is involved
We also saw that Bonney is related to Akainu
And why do you think Oda put Sword near Egghead & is showing us Koby Sub-Plot at same time?
Drake was investigating Beasts Pirates but refused to reveal his Mission even though they were Defeated & his Cover was blown from start anyway, you think his Mission was Kaidou? Ofc not, Drake was Investigating Marine Corruption & it wouldn't be a Sub-Plot that makes sense unless he was Investigating an Admiral!
You think it's coincidence that the Young Marine who stood against Akainu joined Sword at Young Age? or that there seems to be Akainu's Daughter among them? or that Aokiji refused to work for Akainu even though he could have stayed & tried to fix Marines from within, but instead he works for Blackbeard who is worse?
You also think it's coincidence that Akainu hates Dragon so much?
It's obvious that Sword are Investigating Akainu himself & since Drake chose to do that among Beasts Pirates, means they believed there is a connection between Kaidou & Akainu (Personally i believe they were Secret Allies & plotting together to take down World Government).
And as i mentioned above, Akainu being related to Bonney is another Hint
Now if Akainu is related to Kaidou & also Bonney who conveniently mimics Big Mom's Style, it suggests that there was an incident where these Characters met. It should also be noted that Kuma wasn't raised as a King, but later he became one, meaning that whoever were Rulers of his Kingdom before were gone for some reason & Kuma took their Place
We've seen before a similar case where a Non-Royal Man became a King, it happened on Drum Island, and how did Dalton become King? It was after Wapol abandoned his Throne, why? Cuz Blackbeard Pirates Attacked
Same Blackbeard who is big Fan of Xebec & followed in his footsteps when he recruited already Famous Top Criminals, wouldn't it make sense that when BB attacked a Kingdom, he was also following in Xebec's Footsteps? Meaning that Xebec & his Crew once attacked a Kingdom & forced it's Rulers to leave, which led to a New King being appointed, and it would make even more sense if that Kingdom is Kuma's
Another thing to mention is that Fujitora hates Shichibukai System & he also blinded himself indicating that he saw something that made him lose faith in both Sides, indicating that one of Warlords made a Deal or had History with World Government that Fujitora witnessed & made him question everything! It's obviously not Jinbe or Law or Hancock or Buggy ... etc
It's Kuma's Deal that Fujitora most probably witnessed among other things
Oda isn't showing us multiple Sub-Plots at same time and they are Unrelated, that never happened before
All these Sub-Plots are related & Kuma is obviously at the center of it all
These are just Hints, i didn't reveal why i truly think this Flashback is gonna be a Major One
But Oda is using Kuma as a Plot Device to connect so so many Characters so that he makes one Mega Flashback for them all, instead of creating a Flashback for each Character alone which would stretch the story far too much
