Nico and titan army dreams

Inside the lobby, I found an empty bunk and collapsed, sure that I would never be able to sleep. A second later, my eyes closed.
In my dreams, I was back in Hades's garden. The lord of the dead paced up and down, holding his ears while Nico followed him, waving his arms.
"You have to!" Nico insisted.
Demeter and Persephone sat behind them at the breakfast table. Both of the goddesses looked bored. Demeter poured shredded wheat into four huge bowls. Persephone was magically changing the flower arrangement on the table, turning the blossoms from red to yellow to polka-dotted.
"I don't have to do anything!" Hades s eyes blazed. "I'm a god!"
"Father," Nico said, "if Olympus falls, your own palace's safety doesn't matter. You'll fade too."
"I am not an Olympian!" he growled. "My family has made that quite clear."
"You are,'' Nico said. "Whether you like it or not."
"You saw what they did to your mother," Hades said. "Zeus killed her. And you would have me help them? They deserve what they get!"
Persephone sighed. She walked her fingers across the table, absently turning the silverware into roses. "Could we please not talk about that woman?"
"You know what would help this boy?" Demeter mused. "Farming." Persephone rolled her eyes. "Mother—"
"Six months behind a plow. Excellent character building."
Nico stepped in front of his father, forcing Hades to face him. "My mother understood about family. That's why she didn't want to leave us. You can't just abandon your family because they did something horrible. You've done horrible things to them too."
"Maria died!" Hades reminded him.
"You can't just cut yourself off from the other gods!"
"I've done very well at it for thousands of years."
"And has that made you feel any better?" Nico demanded. "Has that curse on the Oracle helped you at all? Holding grudges is a fatal flaw. Bianca warned me about that, and she was right."
"For demigods! I am immortal, all-powerful! I would not help the other gods if they begged me, if Percy Jackson himself pleaded—"
"You're just as much of an outcast as I am!" Nico yelled. "Stop being angry about it and do something

 helpful for once. That's the only way they'll respect you!"
Hades's palm filled with black fire.
"Go ahead," Nico said. "Blast me. That's just what the other gods would expect from you. Prove them right."
"Yes, please," Demeter complained. "Shut him up."
Persephone sighed. "Oh, I don't know. I would rather fight in the war than eat another bowl of cereal. This is boring."
Hades roared in anger. His fireball hit a silver tree right next to Nico, melting it into a pool of liquid metal.
And my dream changed.
I was standing outside the United Nations, about a mile northeast of the Empire State Building. The Titan army had set up camp all around the UN complex. The flagpoles were hung with horrible trophies—helmets and armor pieces from defeated campers. All along First Avenue, giants sharpened their axes. Telkhines repaired armor at makeshift forges.
Kronos himself paced at the top of the plaza, swinging his scythe so his dracaenae bodyguards stayed way back. Ethan Nakamura and Prometheus stood nearby, out of slicing range. Ethan was fidgeting with his shield straps, but Prometheus looked as calm and collected as ever in his tuxedo.
"I hate this place," Kronos growled. "United Nations. As if mankind could ever unite. Remind me to tear down this building after we destroy Olympus."
"Yes, lord." Prometheus smiled as if his master's anger amused him. "Shall we tear down the stables in Central Park too? I know how much horses can annoy you."
"Don't mock me, Prometheus! Those cursed centaurs will be sorry they interfered. I will feed them to the hellhounds, starting with that son of mine—that weakling Chiron."
Prometheus shrugged. "That weakling destroyed an entire legion of telkhines with his arrows." Kronos swung his scythe and cut a flagpole in half. The national colors of Brazil toppled into the
army, squashing a dracaena.
"We will destroy them!" Kronos roared. "It is time to unleash the drakon. Nakamura, you will do
this."
"Y-yes, lord. At sunset?"
"No," Kronos said. "Immediately. The defenders of Olympus are badly wounded. They will not expect a quick attack. Besides, we know this drakon they cannot beat."
Ethan looked confused. "My lord?"
"Never you mind, Nakamura. Just do my bidding. I want Olympus in ruins by the time Typhon reaches New York. We will break the gods utterly!"

 "But, my lord," Ethan said. "Your regeneration."
Kronos pointed at Ethan, and the demigod froze.
"Does it seem," Kronos hissed, "that I need to regenerate?"
Ethan didn't respond. Kind of hard to do when you're immobilized in time.
Kronos snapped his fingers and Ethan collapsed.
"Soon," the Titan growled, "this form will be unnecessary. I will not rest with victory so close. Now, go!"
Ethan scrambled away.
"This is dangerous, my lord," Prometheus warned. "Do not be hasty."
"Hasty? After festering for three thousand years in the depths of Tartarus, you call me hasty? I will slice Percy Jackson into a thousand pieces."
"Thrice you've fought him," Prometheus pointed out. "And yet you've always said it is beneath the dignity of a Titan to fight a mere mortal. I wonder if your mortal host is influencing you, weakening your judgment."
Kronos turned his golden eyes on the other Titan. "You call me weak?"
"No, my lord. I only meant—"
"Are your loyalties divided?" Kronos asked. "Perhaps you miss your old friends, the gods. Would you like to join them?"
Prometheus paled. "I misspoke, my lord. Your orders will be carried out." He turned to the armies and shouted, "PREPARE FOR BATTLE!"
The troops began to stir.
From somewhere behind the UN compound, an angry roar shook the city—the sound of a drakon waking. The noise was so horrible it woke me, and I realized I could still hear it from a mile away.
Grover stood next to me, looking nervous. "What was that?" "They're coming," I told him. "And we're in trouble."
