“Now, as far as I knew, he (Luke) was still sailing around on his demon-infested cruise ship while the chopped-up Lord Kronos re-formed, bit by bit, in a golden sarcophagus, biding his time until he had enough power to challenge the Olympian gods. In demigod-speak, we call this a “problem.”- Percy, 'The Battle of the Labyrinth”

“When Luke had descended into the River Styx, he would've had to focus on something important that would hold him to his mortal life. Otherwise he would've dissolved. I had seen Annabeth, and I had a feeling he had too. He had pictured that scene Hestia showed me—of himself in the good old days with Thalia and Annabeth, when he promised they would be a family. Hurting Annabeth in battle had shocked him into remembering that promise. It had allowed his mortal conscience to take over again, and defeat Kronos. His weak spot—his Achilles heel—had saved us all”

“They kidded him, calling him Admiral, but for once Le accepted the title. This was his ship. He hadn't come this far to be stopped.They would find this House of HAdes. They'd take the Doors of Death. And by the gods, if Leo had to design a grabber arm long enough to snatch Percy and Annabeth out of Tartarus, then that's what he would do.Nemesis wanted to wreak havoc on Gaea? leo would be happy to oblige. He was going to make Gaea sorry she ever messed with Leo Valdez."Yeah," He took once last look at the cityscape of Rome, turning bloodred in the sunset. "Festus, raise the sails. We've got some friends to save.”

“Annabeth,” he said hesitantly, “in New Rome, demigods can live their whole lives in peace.” Her expression turned guarded. “Reyna explained it to me. But, Percy, you belong at Camp Half-Blood. That other life—”“I know,” Percy said. “But while I was there, I saw so many demigods living without fear: kids going to college, couples getting married and raising families. There’s nothing like that at Camp Half-Blood. I kept thinking about you and me…and maybe someday when this war with the giants is over…”It was hard to tell in the golden light, but he thought Annabeth was blushing. “Oh,” she said…“I’m sorry,” he said. “I just…I had to think of that to keep going. To give me hope. Forget I mentioned—”“No!” she said. “Gods, Percy, that’s so sweet.”

“Percy," my father said, "what exactly do you mean?" "Kronos couldn't have risen if it hadn't been for a lot of demigods who felt abandoned by their parents," I said. "They felt angry, resentful, and unloved, and they had a good reason.”

“You're a Demigod Percy, half god and half mortal!”

“Percy, let me go" she croaked. "You can't pull me up."His face was white with effort. She could see in his eyes that he knew it was hopeless."Never," he said. He looked up at Nico, fifteen feet above. "The other side, Nico! We'll see you there. Understand?"Nico's eyes widened. "But-""Lead them!" Percy shouted. "Promise me!""I-I will."Below them, the voice laughed in the darkness. Sacrifices. Beautiful sacrifices to wake the goddess. Percy tightened his grip on Annabeth's wrist. His face was gaunt, scraped and bloody, his hair dusted with cobwebs, but when he locked eyes with her, she thought he had never looked more handsome."We're staying together," he promised. "You're not getting away from me. Never again."Only then did she understand what would happen. A one-way trip. A very hard fall."As long as we're together," she said.She heard Nico and Hazel still screaming for help. She saw sunlight far, far above- maybe the last sunlight she would ever see.Then Percy let go of his ledge, and together, holding hands, he and Annabeth fell into the endless darkness.”
