“Leo drummed his fingers. “Great. I should have installed a smoke screen that makes the ship smell like a giant chicken nugget. Remind me to invent that, next time.”
Hazel frowned. “What is a chicken nugget?”
“Oh, man…” Leo shook his head in amazement. “That's right. You’ve missed the last, like, seventy years. Well, my apprentice, a chicken nugget—”
“Doesn’t matter,” Annabeth interrupted.”

“And,” Annabeth continued, “it reminds me how long we’ve known each other. We were twelve, Percy. Can you believe that?”
“No, he admitted. “So…you knew you liked me from that moment?”
She smirked. “I hated you at first. You annoyed me. Then I tolerated you for a few years. Then—”
“Okay, fine.”
She leaned in and kissed: him a good, proper kiss without anyone watching—no Romans anywhere, no screaming satyr chaperones.
She pulled away. “I missed you, Percy.”
Percy wanted to tell her the same thing, but it seemed too small a comment. While he had been on the Roman side, he’d kept himself alive almost solely by thinking of Annabeth. I missed you didn’t really cover that.”

“Blackjack," Percy said, "this is Piper and Jason. They're friends."
The horse nickered.
"Uh, maybe later," Percy answered.
Piper had heard that Percy could speak to horses, being the son of the horse lord Poseidon, but she'd never seen it in action.
"What does Blackjack want?" she asked.
"Donuts," Percy said. "Always donuts.”

“Jason's fingers itched to draw his sword. He'd met plenty of scary demigods, but he was starting to realize that Nico di Angelo--as pale and gaunt as he looked--might be more than he could handle.”
