In this excerpt from Rick Riordan's "The Mark of Athena," Percy discusses a mysterious incident where he and another character both fainted. Ella reassures him, implying that they were engaging in something beneficial referred to as "sharing." This idea seems to connect with the concept of overcoming challenges, with Ella referencing the significant blackout in American history as a metaphor for their experience.

As Percy tries to make sense of Ella's words, he acknowledges that their recent conversations have been puzzling. Ella suggests that this sharing has a positive impact, indicated by her mention of Hazel's involvement. The exchange highlights a theme of collaboration and its importance in overcoming difficulties, although Percy's confusion reflects the unusual nature of their discussions.
