“Percy: The Heka-what? Annabeth: The Hundred-Handed Ones. They called them that because... well, they had a hundred hands. They were the elder brothers of the Cyclopes. Tyson: Very powerful. Wonderful! As tall as the sky. So strong they can break mountains! Percy: Cool. Unless you're a mountain.”

“He’d learned years ago it was better not to dwell too much on who was related to whom on the godly side of things. After Tyson the Cyclops adopted him as a brother, Percy decided that that was about as far as he wanted to extend the family.”

“Percy: “You asked Poseidon for… me?” Tyson: "For a friend, young cyclopes grow up alone on the streets, learns to make things out of scraps. Learn to survive." Percy: “But that’s so cruel!” Tyson: “Makes us appreciate blessings, not be greedy and mean and fat like Polyphemus. But I got scared. Monsters chased me so much, clawed me sometimes--" Percy: “The scars on your back?” Tyson: “Sphinx on Seventy-second Street. Big Bully. I prayed to Daddy for help.

“Percy (to Annabeth): If I was going to pick one person in the world to reattach my head, I'd pick you.Silena: Awww . . . Percy, that is so sweet!Annabeth: Shut up, Silena.”

“Percy, you're a brave guy," [Annabeth] said. "Just take the compliment. I swear, is it so hard?”

“Whenever Percy stopped by to see [Annabeth], she was so lost in thought that the conversation went something like this:Percy: 'Hey, how's it going?'Annabeth: 'Uh, no thanks.'Percy: 'Okay...have you eaten anything today?'Annabeth: 'I think Leo is on duty. Ask him.'Percy: 'So, my hair is on fire.'Annabeth: 'Okay, in a while.”
