“Percy and Hedge lay on the deck, looking exhausted. Hedge was missing his shoes. He grinned at the sky, muttering, “Awesome. Awesome.” Percy was covered in nicks and scratches, like he’d jumped through a window. He didn’t say anything but he grasped Annabeth’s hand weakly as if to say, Be right with you as soon as the world stops spinning.
Leo, Piper, and Jason, who’d been eating in the mess hall, came rushing up the stairs.
“What? What?” Leo cried, holding a half-eaten grilled cheese sandwich. “Can’t a guy even take a lunch break? What’s wrong?”
“Followed!” Frank yelled again.
“Followed by what? Jason asked.
“I don’t know!” Frank panted. “Whales? Sea monsters? Maybe Kate and Porky!”
Annabeth wanted to strangle the guy, but she wasn’t sure her hands would fit around his thick neck. “That makes absolutely no sense.”

“Leo lowered his screwdriver. He looked at the ceiling and shook his head like, What am I gonna do with this guy?
"I try very hard to be annoying," Leo said. "Don't insult my ability to annoy. And how am I supposed to resent you if you go apologizing? I'm a lowly mechanic. You're like the prince of the sky, son of the Lord of the Universe. I'm supposed to resent you."
"Lord of the Universe?" (Jason)
"Sure, you're all-bam! Lightning man. And 'Watch me fly. I am the eagle that soars-" (Leo)
"Shut up, Valdez." (Jason)
Leo managed a little smile. "Yeah, see. I do annoy you."
"I apologize for apologizing." (Jason)
"Thank you." He went back to work, but the tension had eased between them. Leo still looked sad and exhausted-just not quite so angry.”

“Leo couldn't help smiling. "That could be fun."
"Fun" she said unhappily.
"Blue elephants."
"Blue elephants."
"Kiss me you fool."
"You fool.”

“Correct." Kekrops sounded bitter, like he regretted his decision. "My people were the original Athenians--the gemini."
"Like your zodiac sign?" Percy asked. "I'm a Leo."
"No, stupid," Leo said. "I'm a Leo. You're a Percy.”
