In "The Mark of Athena," Leo expresses his curiosity about his own worth compared to his friends. He wonders about his value in a lighthearted way, acknowledging that he may not be as revered as Percy's or Jason's but still wants to understand how he measures up. This reflection showcases his insecurities and desire for validation among his peers.

Leo specifically questions if he is worth two or three Franks, which illustrates his playful approach to self-worth. His mention of Franks, presumably referring to another character, adds a humorous twist to his introspection. Ultimately, this moment highlights Leo's character dynamics and his need for acceptance within the group.
