I mean you don't have to go with the royal blood shtick, many have mentioned and it stuck on my mind aswell that the shark that shows up at the start of Egghead is following his "true instincts" and couldn't be controled, so a S-flamingo might just be doing that.
I'm sure that setup is going to pay off, my issue is that if the Seraphim do kill Vegapunk, they HAVE to get controled by the gorosei after at some point, because there's no way they'll just be independent.
Also if Vegapunk actually dies, i have no idea what Oda is going to do with Stussy or Bonney.
Kinda lowkey wanted the next chapter now to know what headcanon to go with.
