All of the Seven were in support of saving Nico in Mark of Athena
I have absolutely no idea where the misconception came from that no one on board of the Argo II, except for Hazel, wanted to save, or cared for Nico, but it's starting to really annoy me. So, here’s a little summary of every member of the seven’s and Coach Hedge’s thoughts, feelings and actions when it came to Nico, backed up by exempts from the book
(Safe for Hazel, because… it’s Hazel. Thankfully, there’s no misconception surrounding her, regarding this subject.)
He Immediately agreed to rescue him when the topic came up
“The giants are trying to lure us,” Annabeth said. “They’re assuming we’ll try to rescue him.” “Well, they’re right!” Hazel looked around the table, her confidence apparently crumbling. “Won’t we?” “Yes!” Coach Hedge yelled with a mouthful of napkins. “It’ll involve fighting, right?” (Mark of Athena, Chapter 14)
He Immediately agreed to rescue him when the topic came up
“Hazel, of course we’ll help him,” Frank said. “But how long do we have before… uh, I mean, how long can Nico hold out?” (Mark of Athena, Chapter 14)
He got angry when Leo and Jason suggested that Nico might not be trustworthy
Jason sat forward, his expression grim. “You’re wondering if we can trust the guy. So am I.” Hazel shot to her feet. “I don’t believe this. He’s my brother. He brought me back from the Underworld, and you don’t want to help him?” Frank put his hand on her shoulder. “Nobody’s saying that.” He glared at Leo. “Nobody had better be saying that.” (Mark of Athena, Chapter 14)
She reacted with anger and sadness when the topic of Nico’s predicament came up
She shook her head sadly when he described Nico’s imprisonment in the bronze jar. (Mark of Athena, Chapter 13)
“One seed a day,” Hazel said miserably. “That’s if he puts himself in a death trance.” “A death trance?” Annabeth scowled. “That doesn’t sound fun.” (Mark of Athena, Chapter 14)
Hazel also seemed preoccupied. Maybe she was taking in their surroundings, or maybe she was worrying about her brother. In less than four days, unless they found him and freed him, Nico would be dead. Annabeth felt that deadline weighing on her, too. (Mark of Athena, Chapter 18)
She was in support of rescuing him:
“Fine,” Annabeth muttered. “Hazel, now that we’re in Rome, do you think you can pinpoint Nico’s location?” (Mark of Athena, Chapter 31)
He immediately agreed to rescue him in Son of Neptune:
Not the part about Sammy – that was still too painful to say out loud – but she told them about Gaia’s offer of a fake life, and the goddess’s claim that she’d captured her brother, Nico. Hazel didn’t want to keep that to herself. She was afraid the despair would overwhelm her. Percy rubbed his shoulders. His lips were blue. ‘You – you saved me, Hazel. We’ll figure out what happened to Nico, I promise.’ (Son of Neptune, Chapter 41)
I think my dad is turning a blind eye. I think – I think he wants me to find Nico.’ ‘We’ll find your brother,’ Percy promised. ‘As soon as the ship gets here, we’ll sail for Rome.’ (Son of Neptune, Chapter 52)
He never once considered the possibility of not saving Nico in Mark of Athena
“He disappeared.” Hazel moistened her lips. “I’m afraid…I’m not sure, but I think something’s happened to him.” “We’ll look for him,” Percy promised. “We have to find the Doors of Death anyway.” (Mark of Athena, Chapter 3)
Huddled next to it was a dejected looking boy in tattered jeans, a black shirt, and an old aviator jacket. On his right hand, a silver skull ring glittered. “Nico,” Percy called. But the son of Hades couldn’t hear him. The container was completely sealed. The air was turning poisonous. Nico’s eyes were closed, his breathing shallow. He appeared to be meditating. His face was pale, and thinner than Percy remembered (…) “Nico,” Percy said, “where is this place? We’ll save you.…” (Mark of Athena, Chapter 13)
“Nico is the bait,” she murmured. “Gaea’s forces must have captured him somehow. But we don’t know exactly where they’re holding him.” “Somewhere in Rome,” Percy said. “Somewhere underground. They made it sound like Nico still had a few days to live, but I don’t see how he could hold out so long with no oxygen.” (Mark of Athena, Chapter 13)
But most of the time, Nico sided with the good guys. He certainly didn’t deserve slow suffocation in a bronze jar, and Percy couldn’t stand seeing Hazel in pain. “We’ll rescue him,” he promised her. “We have to. The prophecy says he holds the key to endless death.” (Mark of Athena, Chapter 14)
About a hundred yards away, he spotted a raised dais with two empty oversized praetor chairs. Standing between them was a bronze jar big enough to hold a person. “Look.” He pointed it out to his friends. Piper frowned. “That’s too easy.” “Of course,” Percy said. “But we have no choice,” Jason said. “We’ve got to save Nico.” “Yeah.” Percy started across the room, picking his way around conveyor belts and moving platforms. (Mark of Athena, Chapter 45)
He informed Hazel and the rest of the seven of Nico’s predicament the very morning after he found out
But how can Nico survive that long? We should talk to Hazel.” “Now?” She hesitated. “No. It can wait until morning. I don’t want to hit her with this news in the middle of the night.” (Mark of Athena, Chapter 13)
He told them about his dream—the twin giants planning a reception for them in an underground parking lot with rocket launchers; Nico di Angelo trapped in a bronze jar, slowly dying from asphyxiation with pomegranate seeds at his feet. Hazel choked back a sob. (Mark of Athena, Chapter 14)
He insisted on saving Nico immediately, once he met up with Jason and Piper in Rome
Percy pointed at Piper’s dagger. “Tiberinus said you could find Nico’s location…you know, with that.” Piper bit her lip. The last thing she wanted to do was check Katoptris for more terrifying images. “I’ve tried,” she said. “The dagger doesn’t always show what I want to see. In fact, it hardly ever does.” “Please,” Percy said. “Try again.” (Mark of Athena, Chapter 41)
Piper dropped the blade. “What’s wrong?” Jason asked. “It was showing us something.” Piper felt like the boat was back on the ocean, rocking under her feet. “We can’t go there.” Percy frowned. “Piper, Nico is dying. We’ve got to find him. Not to mention, Rome is about to get destroyed.” (Mark of Athena, Chapter 41)
“We should wait for the others,” she said. “Hazel, Frank, and Leo should be back soon.” “We can’t wait,” Percy insisted. (Mark of Athena, Chapter 41)
He felt anxious when thinking about Nico and the possibility of him dying
The vision zoomed in again. Inside the jar, Nico di Angelo was curled in a ball, no longer moving, all the pomegranate seeds eaten. “We’re too late,” Jason said. “No,” Percy said. “No, I can’t believe that. Maybe he’s gone into a deeper trance to buy time. We have to hurry.” (Mark of Athena, Chapter 41)
Otis trudged over to the dais, stopping occasionally to do a plié. He knocked over the jar, the lid popped off, and Nico di Angelo spilled out. The sight of his deathly pale face and too-skinny frame made Percy’s heart stop. Percy couldn’t tell whether he was alive or dead. He wanted to rush over and check, but Ephialtes stood in his way. (Mark of Athena, Chapter 45)
At Otis’s feet, Nico shuddered. Percy felt like a hellhound hamster wheel somewhere in his chest had started moving again. At least Nico was alive. (Mark of Athena, Chapter 45)
Jason and Piper closed ranks on either side of Percy (…)“We’re here,” Percy said, which sounded kind of obvious once he had said it. “Let our friend go.” (Mark of Athena, Chapter 45)
“Okay.” Percy decided not to comment on the Hawaiian shirt. “Now, about our friend…” “Oh, him,” Ephialtes sneered. “We were going to let him finish dying in public, but he has no entertainment value. He’s spent days curled up sleeping. What sort of spectacle is that? Otis, tip over the jar.” (Mark of Athena, Chapter 45)
He was careful to make sure Nico would not get injured while he, Jason and Piper fought the giants:
Percy was ready to slice this giant in half and get out of there, but Otis was standing over Nico. If a battle started, Nico was in no condition to defend himself. Percy needed to buy him some recovery time. (Mark of Athena, Chapter 45)
Percy glanced over at Nico, who was just starting to move. Percy wanted him to be at least conscious enough to crawl out of the way when the fighting started. (Mark of Athena, Chapter 45)
She immediately agreed to rescue him (There’s a pattern here)
“And he has five seeds left,” Percy said. “That’s five days, including today. The giants must have planned it that way, so we’d have to arrive by July first. Assuming Nico is hidden somewhere in Rome—” “That’s not much time,” Piper summed up. She put her hand on Hazel’s shoulder. “We’ll find him. (Mark of Athena, Chapter 14)
“We’ll rescue him,” he promised her. “We have to. The prophecy says he holds the key to endless death.” “That’s right,” Piper said encouragingly. “Hazel, your brother went searching for the Doors of Death in the Underworld, right? He must’ve found them.” (Mark of Athena, Chapter 14)
She felt anxious when she thought about Nico’s predicament
Piper tried to imagine what Nico di Angelo was feeling, stuck in a jar with only two pomegranate seeds left to sustain him, and no idea whether he would be rescued. It made Piper anxious to reach Rome, even though she had a horrible feeling she was sailing toward her own sort of prison—a dark room filled with water. “Nico must have information about the Doors of Death,” Piper said. “We’ll save him, Hazel. We can make it in time. (Mark of Athena, Chapter 25)
Piper slipped it back into its sheath, trying to keep her hands from shaking. She hoped that Percy was right, and Nico was still alive. (Mark of Athena, Chapter 41)
She protected Nico, once he had escaped from the bronze jar:
Nico stirred. Otis looked down at him. His snaky feet flicked their tongues at Nico’s head. “Plus!” Piper said quickly. “Plus, we could do some dance moves as we’re escaping. Perhaps a ballet number!” Otis forgot all about Nico. He lumbered over and wagged his finger at Ephialtes. (Mark of Athena, Chapter 45)
He caught a brief glimpse of Piper leaping across a hopscotch pattern of fiery pits, making her way toward Nico, who was dazed and weaponless and being stalked by a pair of leopards. (Mark of Athena, Chapter 46)
At the dais, Piper stood guard over Nico as the leopards advanced. She aimed her cornucopia and shot a pot roast over the cats’ heads. It must have smelled pretty good, because the leopards raced after it. (Mark of Athena, Chapter 46)
Across the room, sandbags rained down around Piper and Nico. Piper tried to pull Nico to safety, but one of the bags caught her shoulder and knocked her down. (Mark of Athena, Chapter 46)
I’m going to sum Jason and Leo up together, because their perspective is very similar on this subject.
Now, obviously, both of them had some doubts at the beginning:
Uh…” Leo shifted in his chair. “One thing. The giants are expecting us to do this, right? So we’re walking into a trap?” Hazel looked at Leo like he’d made a rude gesture. “We have no choice!” “Don’t get me wrong, Hazel. It’s just that your brother, Nico… he knew about both camps, right?” “Well, yes,” Hazel said “He’s been going back and forth,” Leo said, “and he didn’t tell either side.” Jason sat forward, his expression grim. “You’re wondering if we can trust the guy. So am I.” Hazel shot to her feet. “I don’t believe this. He’s my brother. He brought me back from the Underworld, and you don’t want to help him?” Frank put his hand on her shoulder. “Nobody’s saying that.” He glared at Leo. “Nobody had better be saying that.” Leo blinked. “Look, guys. All I mean is—” “Hazel,” Jason said. “Leo is raising a fair point. I remember Nico from Camp Jupiter. Now I find out he also visited Camp Half-Blood. That does strike me as… well, a little shady. Do we really know where his loyalties lie? We just have to be careful.” (Mark of Athena, Chapter 14)
If I am being honest, this is actually a completely valid point. The way that both of them phrased it was pretty harsh, especially considering the fact that Hazel was sitting right next to them, but the point in of itself, is not preposterous.
Leo had never even met Nico, and Jason had only seen him a couple of times in Camp Jupiter, before this quest. Finding out that a demigod, neither of them really knew, had known about both camps long before any other half-blood did, and is now being used as part of a trap is suspicious (even if none of that is Nico’s fault).
But ignoring that, this hesitance to saving Nico, only lasted for like one or two chapters. After this conversation, both Leo and Jason were completely in support of saving Nico throughout the entire rest of Mark of Athena:
Instead, we could send out a decoy to trick the eagles. We take the ship on a detour, go the long way to Charleston, and get there tomorrow morning—” Hazel started to protest, but Leo raised his hand. “I know, I know. Nico’s in trouble and we have to hurry.” (Mark of Athena, Chapter 17)
Hazel glanced at the evening sun, which was almost to the horizon. “We need to go fast. We’ve burned another day, and Nico only has three more left.” “We can do it,” Leo promised. (Mark of Athena, Chapter 21)
“She’s right,” Hazel said. “After today, Nico has less than two days. The fish-centaurs said we have to rescue him. He’s essential to the quest somehow.” She looked around defensively, as if waiting for someone to argue. No one did. (Mark of Athena, Chapter 25)
Jason suddenly looked as though his brownie with peach preserves didn’t taste so good. “Which will put us in Rome on the last possible day for Nico. Twenty-four hours to find him—at most.” (Mark of Athena, Chapter 25)
“Good idea,” Percy said. “How about we plan to meet back here at… what?” “Three this afternoon?” Jason suggested. “That’s probably the latest we could rendezvous and still hope to fight the giants and save Nico. (Mark of Athena, Chapter 31)
About a hundred yards away, he spotted a raised dais with two empty oversized praetor chairs. Standing between them was a bronze jar big enough to hold a person. “Look.” He pointed it out to his friends. Piper frowned. “That’s too easy.” “Of course,” Percy said. “But we have no choice,” Jason said. “We’ve got to save Nico.” (Mark of Athena, Chapter 45)
Leo was even prepared to open Nemesis’ fortune cookie to find out where Nico was being kept:
The fortune cookie in his tool belt started to feel heavier. Last night, as they flew from Atlanta, Leo had lain in his cabin and thought about how angry he’d made Hazel. He had thought about ways he could make it right. Soon you will face a problem you cannot solve, Nemesis had said, though I could help you…for a price. Leo had taken the fortune cookie out of his tool belt and turned it in his fingers, wondering what price he would have to pay if he broke it open. Maybe now was the moment. “I’d be willing,” he told Hazel. “I could use the fortune cookie to find your brother.” Hazel looked stunned. (Mark of Athena, Chapter 21)
