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

“Once the others were below, Hazel and Leo faced each other awkwardly. They were alone except for Coach Hedge, who was back on the quarterdeck singing the Pokémon theme song. The coach had changed the words to: Gotta Kill ’Em All, and Leo really didn’t want to know why.”

“They had a silent staring contest, but Percy didn’t back down. When he and Annabeth started dating, his mother had drummed it into his head: It’s good manners to walk your date to the door. If that was true, it had to be good manners to walk her to the start of her epic solo death quest.”

“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.”
