“I could have killed you.”
“Or I could have killed you,” Percy said.
Jason shrugged. “If there’d been an ocean in Kansas, maybe.”
“I don’t need an ocean—”
“Boys,” Annabeth interrupted, “I’m sure you both would’ve been wonderful at killing each other. But right now, you need some rest.”
Food first,” Percy said. “Please?”

“Hey, can I see that sword you were using?"
I showed him Riptide, and explained how it turned from a pen into a sword just by uncapping it.
"Cool! Does it ever run out of ink?"
"Um, well, I don't actually write with it."
"Are you really the son of Poseidon?"
"Well, yeah."
"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.)”

“The throne rumbled. A wave of gale-force anger slammed into me.
WHO DARES-
The voice stopped abruptly, The anger retreated, which was a good thing, because just those two words had almost blasted my mind to shreds.
Percy. My fathers voice was still angry but more controlled. What-exactly-are you doing on my throne?
"I'm sorry, Father," I said. "I needed to get your attention."
This was a very dangerous thing to do. Even for you. If I hadn't looked before I blasted, you would now be a puddle of seawater.”

“Whenever Percy stopped by to see [Annabeth], she was so lost in thought that the conversation went something like this:
Percy: 'Hey, how's it going?'
Annabeth: 'Uh, no thanks.'
Percy: 'Okay...have you eaten anything today?'
Annabeth: 'I think Leo is on duty. Ask him.'
Percy: 'So, my hair is on fire.'
Annabeth: 'Okay, in a while.”
