In the scene from "The Last Olympian," Zeus expresses gratitude towards Hades for his support, a moment that seems difficult for him to articulate. This acknowledgment highlights the often contentious relationship between the brothers, suggesting a rare moment of unity amidst their usual rivalries. The clearing of his throat before speaking indicates the significance of Hades's contribution and Zeus's struggle to voice appreciation.

Hades, portrayed with a smug demeanor, seems to take pride in this recognition, which may be a rare victory for him given his usually misunderstood role. Nico's happiness in this moment underscores the familial bond and relief among them, adding depth to their characters and showcasing how even amidst chaos, moments of gratitude and familial pride can shine through.
