“Your former friend Luke " Poseidon corrected. "He once promised things like that. He was Hermes's pride and joy. Just bear that in mind Percy. Even the bravest can fall.”

“After the satyrs filed in to dinner, the Hermes cabin brought up the rear. They were always the biggest cabin. Last summer it had been led by Luke, the guy who fought with Thalia and Annabeth on top of Half-Blood Hill. For a while, before Poseidon had claimed me, I'd lodged in the Hermes cabin. Luke had befriended me...and then he'd tried to kill me.”

“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. Soon the people at Meriwether found me. Mey you. Biggest blessing ever. Sorry I said Poseidon was mean. He sent me a brother.”

“A little background: Annabeth used to adventure with Hermes's son Luke. Over time, Annabeth developed a crush on Luke. As Annabeth got older, Luke developed feelings for her, too. Luke turned evil. Hermes blamed Annabeth for not preventing Luke from turning evil. Annabeth blamed Hermes for being a rotten dad and giving Luke the capacity to become evil in the first place. Luke died in war. Hermes and Annabeth blamed each other.Confused? Welcome to my world.”

“You speak horse?" Hazel asked."Speaking to horses is a Poseidon thing," Percy said. "Uh, I mean a Neptune thing.""Then you and Arion should get along fine," Hazel said. "He's a son of Neptune too."Percy turned pale. "Excuse me?”

“Blood trickled from the corner of her (Annabeth) mouth. She croaked, "Family, Luke. You promised."Luke stared at the knife in Annabeth's hand, the blood on her face. "Promise." Then he gasped like he couldn't get air. "Annabeth . . ." But it wasn't the Titan's voice. It was Luke's. He stumbled forward like he couldn't control his own body. "You're bleeding. . . ." He gasped again."He's changing. Help. He's . . . he's almost ready. He won't need my body anymore. Please—""The knife, Percy," Annabeth muttered. Her breath was shallow. "Hero . . . cursed blade . . ."Luke turned and collapsed, clutching his ruined hands."Please, Percy . . ."Luke seemed to know what I was thinking. He moistened his lips. "You can't . . . can't do it yourself. He'll break my control. He'll defend himself. Only my hand. I know where. I can . . . can keep him controlled."I raised the knife to strike. Then I looked at Annabeth, at Grover. And I finally understood what she'd been trying to tell me. You are not the hero, Rachel had said. It will affect what you do. The line from the great prophecy echoed in my head: A hero's soul, cursed blade shall reap. My whole world tipped upside down,and I gave the knife to Luke.I watched as Luke grasped the hilt he stabbed himself”
