The protagonist feels a strong longing to be at Camp Half-Blood, where he experienced deeper fulfillment during his time with Piper and Leo than at Camp Jupiter. His memories of camaraderie and satisfaction at Half-Blood contrast sharply with his years at the other camp, suggesting a stronger emotional connection and sense of belonging.
Moreover, the possibility of meeting his father at Camp Half-Blood adds to his desire to be there. He considers the infrequent visits of the gods at Camp Jupiter, which makes the prospect of encountering his divine parent more appealing at the other camp, enhancing his yearning for a place where he believes he might truly belong.
