„Will Solace sighed. He was, of course, tied to Nico. He propped his elbow on Nico’s shoulder as if the son of Hades were a convenient shelf.“

— Rick Riordan
„You will suffer, son of Hades!’What else is new? Nico thought.“
— Rick Riordan
„I am Nico Di Angelo, son of Hades. I control the shadows. They do not control me.“
— Rick Riordan
„The coach could do a goat-hoof tap dance around Nico’s head and the son of Hades wouldn’t even budge.“
— Rick Riordan
„Nico wasn't sure whether to kick himself or Will Solace. If he hadn’t been so distracted bickering with the son of Apollo, he would never have allowed the enemy to get so close.“
— Rick Riordan
„This did not seem to reassure Nico.“I don’t like being in the dark,” he muttered.An odd complaint for a child of Hades, but I understood what he meant.“
— Rick Riordan
„He turned, registering a face with blond hair, and for a split second he thought it was Will Solace. When Nico realized it was Jason, he was disappointed. Then he felt angry with himself for feeling that way.“
— Rick Riordan
„Child of Hades, what more could I do to you? You are perfect! So much sorrow and pain!’ Nico gasped. His eyes flew open.“
— Rick Riordan
„The farm god rolled his eyes. He pointed at the corn plant, and BAM! Nico di Angelo appeared in an exposion of corn silk. Nico looked around in panic. "I-I had the weirdest nightmare about popcorn.“
— Rick Riordan
„No,’ Nico said. ‘Getting a second life is one thing. Making it a better life, that’s the trick.’ As soon as he said it, Nico realized he could’ve been talking about himself. He decided not to bring that up.“
— Rick Riordan
„The older Nico got, the more juvenile Percy seemed to him, though Percy was three years older. Nico found his sense of humour equal parts endearing and annoying. He decided to concentrate on the annoying.“
— Rick Riordan
„Frank heard a laugh behind him. He glanced back and couldn't believe what he saw. Nico di Angelo was actually smiling."That's more like it," Nico said. "Let's turn this tide!“
— Rick Riordan
„Dalmatia,” Nico said, making Jason jump. Jason wished he could put a bell around Nico di Angelo’s neck to remind him the guy was there. Nico had this disturbing habit of standing silently in the corner, blending into the shadows.“
— Rick Riordan
„The baby!’ Nico grinned, which hurt his face muscles. He wasn’t used to making that expression. ‘Mellie and the kid are all right?“
— Rick Riordan
„Don't talk to my sister that way." Nico said. His voice quivered, but I was impressed that he had the guts to say anything at all. — Percy“
— Rick Riordan
„Nico," he said gently, "I've seen a lot of brave things. But what you just did? That was maybe the bravest.“
— Rick Riordan
„He had arrived at Camp Half-Blood thanks to Apollo. Now, on what would likely be his last day at camp, he was stuck with a son of Apollo.‘Whatever,’ Nico said. ‘But we have to hurry. And you’ll follow my lead.“
— Rick Riordan
„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.“
— Rick Riordan
„Nico found a sort of freedom in knowing that eventually, no matter what happened, he would end up at the foot of his father’s throne.“
