Percy was a new demigod. You, Annabeth and Grover were the people Percy chose for his first quest. Retrieve Zeus bolt back to him. Not easy at all..

Annabeth was walking away of the famous tree, Thalia's tree. Annabeth was half-arguing with Percy because he wasn't taking her seriously when she said this tree was Thalia.

"Thalia was the bravest demigod she ever met, she fought valiantly, and she met a hero's fate." Annabeth stated with a serious expression, her tone was stern.

Percy shrugged, holding a box with his hands. "She met a pinecone's fate" He responded nonchalantly, clearly not understanding any of that story.

Grover winced when he saw Annabeth dead glare to Percy, Percy looked away as Annabeth and you kept walking.
