“We need music," Nico said. "How's your singing?"
"Um, no. Can't you just, like, tell it to open? You're the son of Hades and all."
"It's not so easy. We need music."
I was pretty sure if I tried to sing, all I would cause was an avalanche.”

“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."

"Son of Hades." Kronos spit on the ground. "Do you love death so much you wish to experience it?"
"Your death," Nico said, "would be great for me."
"I'm immortal, you fool! I have escaped Tartarus. You have no business here, and no chance to live."
Nico drew his sword-three feet of wicked sharp Stygian iron, black as a nightmare. "I don't agree.”
