“What if it lines up like it did in the Trojan War ... Athena versus Poseidon?"
"I don't know. But I just know that I'll be fighting next to you."

“Can you surf really well, then?"
I looked at Grover, who was trying hard not to laugh.
"Jeez, Nico," I said. "I've never really tried."
He went on asking questions. Did I fight a lot with Thalia, since she was a daughter of Zeus? (I didn't answer that one.) If Annabeth's mother was Athena, the goddess of wisdom, then why didn't Annabeth know better than to fall off a cliff? (I tried not to strangle Nico for asking that one.) Was Annabeth my girlfriend? (At this point, I was ready to stick the kid in a meat-flavored sack and throw him to the wolves.)”

“Once she was gone, I knelt next to Annabeth and felt her forehead. She was still burning up.
"You're cute when you're worried," she muttered. "Your eyebrows get all scrunched together."
"You are not going to die while I owe you a favor," I said. "Why did you take that knife?"
"You would've done the same for me."
It was true. I guess we both knew it. Still, I felt like somebody was poking my heart with a cold metal rod.”

“Monkey bar," Annabeth said. "I'm great at these." She leaped onto to the first rung and start swinging her way across. She was scared of tiny spiders, but not of plummeting to her death from a set of monkey bars. Go figure.”
