-Buckingham Stussy is a Celestial Dragon, who abandoned Mary Geoise after falling in love with Whitebeard
-The Clone Stussy was taken in and raised by the Gorosei as a quasi-Celestial Dragon, and has maximum authority over the Seraphim
-Stussy wants to maintain her cover, so she is trying to kill Lucci
-Once the Strawhats and Punks leave, Stussy will destroy Egghead, and report to the WG that she thinks there were no survivors
