When Apollo, Meg McCaffrey, Piper Mclean and Jason Grace were captives aboard the Julia Drusilla XXVI, Florence wanted to call it in, but his partner, Grunk told him not to, saying that if anything went wrong, it was Amax who would be punished. When Apollo and his friends had killed their captors, Florence and Grunk came charging into the room, but Piper shouted "Stop!" in charmspeak and Florence face-planted on the carpet. Piper then ties him, gags him and takes his combat helmet.
It is unknown whether Florence was killed when the Julia Drusilla went down or not.
