I think Fujitora and Greenbull will be nearby considering they just sent Weevil in there but I don’t think he will join Cross Guild because of his anti-pirate views. He will probably let them go after seeing it’s too late to stop them or got hard countered by Mihawk.
The glimpe of his backstory being a war criminal (WG propaganda term to villify his good deeds) and openly hating WG made me think he will defect after this and never really had a choice between staying in prison or being an admiral.
This will be the beginning of the Navy downfall.
Aokiji = BB Pirates but is using them to dismantle the WG in his own way.
Kizaru = Was a Revolutionary army double agent but quits being admiral to join Dragon after Egghead with Sentomaru when he finally resolves his “unclear justice”.
Fujitora = Revolutionary army considering his “brotherly” ties with Kizaru and Akainu who was close to Dragon.
Akainu = Unclear but will redeem himself by going against WG orders and go all out on his way.
Garb, Sengoku and Smoker with 100s of VA level loyalist = Sword.
