fate of forever battling the maeonian drakon despite Percy and Annabeth's belief that the line of the Prophecy of Seven about "foes bare arms to the Doors of Death" refers to the four of them: two demigods, a Titan and a Giant who should be mortal enemies under normal circumstances. Ultimately, despite the return of his memories, Bob takes Percy's advice to heart that he should take the parts of Iapetus' past that he wants while leaving everything else behind and continues to side with them, showing disgust for his evil past.
