How we cite our quotes: (Chapter.Paragraph)
Quote #1
He knew he shouldn't be in this place. He shouldn't befriend these people, and certainly he shouldn't date one of them. (7.10)
Roman and Greek demigods seem to have an instinctual antipathy to each other. Jason feels it's wrong to be at Camp Half-Blood. The idea that different groups of people have some sort of natural dislike for each other seems kind of icky, though the book doesn't actually seem to take it all that seriously (Jason, Piper, and Leo get along fine, after all).
Quote #2
"Seriously," Leo said. "Could you not show off?"
"Creak?" the dragon asked.
"You need a name," Leo decided. "I'm calling you Festus."
Festus tilted his head and snorted steam. Then he lowered his back in an unmistakable gesture. He wanted Leo to climb on. (12.50-53)
Leo's friendship with Festus is one of the sweetest in the book. Pets are the best friends, basically—especially if they have giant claws and can breath fire.
Quote #3
Jason worried that he'd let his friends into a trap. If thing went bad, he wasn't sure he could get them out alive. Without thinking about it, he took Piper's hand for reassurance.
She raised her eyebrows, but she didn't let go.
"It'll be fine," she promised. "Just a talk, right?" (19.5-7)
This is almost as cute as Leo with Festus. Jason doesn't have a whole lot of personality (click on over to the "Characters" section for more on that), but he comes closest when he's relying on Piper. Other people make him better, in other words, which is how friendship is supposed to work.
