Very simple premise.
Fujitora is only allowed to set foot in any marine base after he captured Goofy and Law
It's something Oda remembers years later, making it a relevant side plot:
Law unlike Kid was allowed to escape because he has to be captured by Fuji:
It's pretty delusional to think that one of marine Admirals won't ever be seen in new Marine HQ until the end and that we won't have another 3 admiral shot :
