When he got his memory back, he got his memory back. This time though, he was doubly mad at Hera or Juno or whatever she was going by these days.

Nico was the first to greet him after they fought off the giants. "Hi, Percy."

"Nico," Percy sighed. "Didn't expect you here."

Nico shoved his hands into his pockets. "Yeah, well. I am. I'm going with you guys. I don't really care if the prophecy says otherwise."

"Wisdom's daughter walks alone / The Mark of Athena burns through Rome / Twins snuff out the angels breath / Who holds the key to endless death / The giants' bane stands gold and pale / Won through pain from a woven jail," Percy quoted. He looked at Nico disapprovingly. "I'm not asking you to go through all that crap again because it was so crappy. Just… what if by going with us, that's how you get caught?"

"Whatever happens is going to happen," Nico shrugged. "But the Doors of Death… Tartarus… you aren't going to go through that again either. Let me help."

Percy sighed. "Fine. Whatever."

Nico poked his new purple praetor cloak. "Nice cloak, Praetor Jackson."

"I'm resigning tomorrow when Jason get here," Percy scowled. "I still feel like I took it away from him." He shuffled his feet. "Anyway, we have to address the Legion tomorrow before, you know, a giant warship appears."

Nico's expression was unreadable. "Right."

.

The senate met the next day. Percy and Reyna had their praetor outfits. Nico did not wear his black toga which Percy had to admit looked utterly ridiculous. Instead, the son of Hades came dressed in his black jeans and aviator jacket.

"Ambassador of Pluto-" Octavian started.

Nico glared. "Shut up, Octavian. I don't want to wear the stupid toga."

Percy cleared his throat. "Uh, so I'm not really sure how these things go, but in like an hour some demigods are going to arrive on this giant warship. Four demigods to be precise."

"Four of the seven," Hazel added, looking excited. "From the Prophecy of Seven."

Reyna raised an eyebrow. "Do you know who they are?"

Percy hesitated. "Jason Grace for one."

This sent the senate into an uproar. Senators and Lares were shouting about how Jason was missing for nearly a year and why was he only coming back now.

"Silence!" Hylla shouted. She nodded at her sister.

Reyna took a deep breath. "Thank you, Hylla. Jason is part of the Seven then? I assume you yourself are too, Percy. Do you know who else?"

"Jason and I, yeah," Percy confirmed. "Plus Frank and Hazel. The message I got was from someone named Leo, so I assume he's going. Other than that, I'm not sure."

Nico raised a hand. "I know."

Octavian looked especially deranged, Percy noted. His nostrils flared and his face was an ugly purple.

"How do you just happen to know?" he demanded. "Did your father tell you this as well?"

Nico blinked. "No. If you'd just listen, it would make much more sense. There's another Camp for demigods. It's different than Camp Jupiter though. The other camp is called Camp Half-Blood, and it's a Greek camp."

"That's where Jason is," Percy said quickly. "That's where I came from. Hera, Juno to you all, decided to do an exchange student thing. She switched Jason and I so we could bring the two camps together. The war with Gaea is going to take us working together to win."

Reyna frowned, digesting this. "So in a matter of minutes, a warship built by Jason and these Greeks will arrive to take you along with Centurion Zhang and Hazel Levesque to fulfill the Prophecy of Seven?"

"Exactly," Percy nodded gratefully. "So, yeah. I'm actually a Greek demigod. Son of Poseidon, not Neptune." He looked at Nico. "Can you explain who else is going?"

Nico nodded. "The other three are Leo Valdez, Piper McLean, and Annabeth Chase. Children of Hephestus, Aphrodite, and Athena respectively."

"Annabeth," Percy mumbled with a goofy smile. "I miss her."

"I bet you do, Kelp Head," Nico snorted. "I know she missed you."

Frank looked hesitant. "Uh, Nico? How do you know all this?"

"Oh, well, I went to Camp Half-Blood first," Nico said, looking surprised. "My father is Hades. I am Greek, but he sent me here so I would know about the Roman camp in case something happened."

"Why should we trust these Greeks?" Octavian asked. He looked at Nico suspiciously. "Our own Ambassador to Pluto admits he deceived us. How can we trust that this isn't part of the Greek's plan to destroy us?"

The senate shifted restlessly, but most of them were too afraid to interrupt Octavian while he was on a roll. Meanwhile the sun climbed into the sky, shining through the broken senate roof and giving Octavian a natural spotlight.

"The camp is safe," Octavian continued. "I'll be the first to congratulate our heroes for bringing back the legion's eagle and so much Imperial gold! Truly we have been blessed with good fortune. But why do more? Why tempt fate?"

"I'm glad you asked." Percy stood, taking the question as an opening.

Octavian stammered, "I wasn't—"

"—part of the quest," Percy said. "Yes, I know. And you're wise to let me explain, since I was."

Some of the senators snickered. Octavian had no choice but to sit down and try not to look embarrassed.

"Gaea is waking," Percy said. "We've defeated two of her giants, but that's only the beginning. The real war will take place in the old land of the gods. The quest will take us to Rome, and eventually to Greece."

An uneasy ripple spread through the senate.

"I know, I know," Percy said. "You've always thought of the Greeks as your enemies. And there's a good reason for that. I think the gods have kept our two camps apart because whenever we meet, we fight. But that can change. It has to change if we're to defeat Gaea. That's what the Prophecy of Seven means. Seven demigods, Greek and Roman, will have to close the Doors of Death together." Percy swallowed back the bitter taste in his mouth. Bob and Damasen.

"Ha!" shouted a Lar from the back row. "The last time a praetor tried to interpret the Prophecy of Seven, it was Michael Varus, who lost our eagle in Alaska! Why should we believe you now?"

Octavian smiled smugly. Some of his allies in the senate began nodding and grumbling. Even some of the veterans looked uncertain.

"I carried Juno across the Tiber," Percy reminded them, speaking as firmly as he could. "She told me that the Prophecy of Seven is coming to pass. Mars also appeared to you in person. Do you think two of your most important gods would appear at camp if the situation wasn't serious?"

"He's right," Gwen said from the second row. "I, for one, trust Percy's word. Greek or not, he restored the honor of the legion. You saw him on the battlefield last night. Would anyone here say he is not a true hero of Rome?"

Nobody argued. A few nodded in agreement.

Reyna stood. Percy watched her anxiously. Her opinion could change everything—for better or worse.

"You claim this is a combined quest," she said. "You claim Juno intends for us to work with this—this other group, Camp Half-Blood. Yet the Greeks have been our enemies for eons. They are known for their deceptions."

"Maybe so," Percy said. "But enemies can become friends. A week ago, would you have thought Romans and Amazons would be fighting side by side?"

Queen Hylla laughed. "He's got a point."

"The demigods of Camp Half-Blood have already been working with Camp Jupiter," Percy said. "We just didn't realize it. During the Titan War last summer, while you were attacking Mount Othrys, we were defending Mount Olympus in Manhattan. I fought Kronos myself."

Reyna backed up, almost tripping over her toga. "You… what?"

"I know it's hard to believe," Nico said. "But everything we're saying is true."

"Oh, come on!" Octavian shouted. "They're making things up, now. You fought Saturn?" he scoffed.

"A half-blood of the eldest gods / Shall reach sixteen against all odds ," Nico recited. " And see the world in endless sleep / A hero's soul cursed blade shall reap / A single choice shall end his days / Olympus to preserve or raze."

"Raze with a z," Percy added. "That was the last Great Prophecy. The half-blood was me, and the hero was… the hero was Luke. Look, we can argue all day about this, or you can trust Nico and me when we say these people are no threat. Are you really willing to fight Jason Grace? He's going to be on that ship."

Reyna frowned. "It is a lot to believe. Jason is coming back with a bunch of Greek demigods? You say they're going to appear in the sky in a heavily armed warship, but we shouldn't be worried."

"Yes." Percy looked over the rows of nervous, doubtful spectators. "Just let them land. Hear them out. Jason will backup everything I'm telling you. I swear it on my life."

"On your life?" Octavian looked meaningfully at the senate. "We will remember that, if this turns out to be a trick."

Right on cue, a messenger rushed into the Senate House, gasping as if he'd run all the way from camp. "Praetors! I'm sorry to interrupt, but our scouts report—"

"Ship!" Tyson said happily, pointing at the hole in the ceiling. "Yay!

Sure enough, a Greek warship, the Argo II, appeared out of the clouds, about a half a mile away, descending toward the Senate House. As it got closer, Percy could see bronze shields glinting along the sides, billowing sails, and a familiar-looking figurehead shaped like a metal dragon. On the tallest mast, a big white flag of truce snapped in the wind. To his surprise, a giant smiley face was painted on the bottom with the word "WASSUP" next to it. He held back a smile. Must have been Leo's idea.

"Praetors!" the messenger cried. "What are your orders?"

Octavian shot to his feet. "You need to ask?" His face was red with rage. He was strangling his teddy bear. "The omens are horrible! This is a trick, a deception. Beware Greeks bearing gifts!" He jabbed a finger at Percy. "His friends are attacking in a warship. He has led them here. We must attack!"

"No," Percy said firmly. "You all raised me as praetor for a reason. I will fight to defend this camp with my life. But these aren't enemies. I say we stand ready, but do not attack. Let them land. Let them speak. If it is a trick, then I will fight with you, as I did last night. But it is not a trick."

All eyes turned toward Reyna.

She studied the approaching warship. Her expression hardened. If she vetoed Percy's orders…well, he didn't know what would happen. Chaos and confusion, at the very least. Most likely, the Romans would follow her lead. She'd been their leader much longer than Percy.

"Hold your fire," Reyna said. "But have the legion stand ready. Percy Jackson is your duly chosen praetor. We will trust his word—unless we are given clear reason not to. Senators, let us adjourn to the forum and meet our…new friends."

The senators stampeded out of the auditorium—whether from excitement or panic, Percy wasn't sure. Tyson ran after them, yelling, "Yay! Yay!" with Ella fluttering around his head.

Octavian gave Percy a disgusted look, then threw down his teddy bear and followed the crowd.

Reyna stood at Percy's shoulder.

"I support you, Percy," she said. "I trust your judgment. But for all our sakes, I hope we can keep the peace between our campers and your Greek friends."

"We will," he promised. "You'll see."

She glanced up at the warship. Her expression turned a little wistful. "You say Jason is aboard… I hope that's true. I've missed him." She marched outside, leaving Percy alone with Nico, Hazel, and Frank.

"They're coming down right in the forum," Frank said nervously. "Terminus is going to have a heart attack."

"Percy," Hazel said, "you swore on your life. Romans take that seriously. If anything goes wrong, even by accident, Octavian is going to kill you. You know that, right?"

Percy smiled. Unlike before, it wasn't really a risk. He knew Jason would back everything up. If he was being honest, he quite missed the blonde haired son of Jupiter. Which reminded him of another blonde. Annabeth was on that ship. Finally, he would see her again.

"Alright, Kelp Head," Nico grumbled. "I know who you're thinking about. You'll see her soon, Lover Boy."

Percy rolled his eyes. "Uh huh. How's Will, Nico?"

"I hate you," Nico muttered darkly.

Percy laughed and threw his arms around Hazel and Frank. "Come on. Let me introduce you to my other family."

A/N: Little choppy, but since Nico obviously never went to look for the Doors of Death this time, he'll still be at Camp Jupiter. Seeing as he's part of the time traveling trio, he wants to go with the Seven to stop Gaea and prevent the war from becoming how bad it became.
