Hello everyone! Happy Easter! Hope you are all having an amazing weekend. If you don't celebrate Easter, then I still hope you're having an amazing weekend! I just want to say a huge thank you for all the amazing reviews you guys have left. Honestly when I say they make me so happy I really mean it. They've really encouraged me to keep going and even given me a few ideas to expand the story which I hope you will all like. I just wanted to clarify something that I definitely should have done at the beginning but didn't because I'm an idiot. I didn't include Thor in this story so far as because he is a God and related to the Norse Gods, I thought it might make it complicated as he might know of the Greek/Roman Gods and therefore give Jason and Percy away far too soon. Or at least, if he didn't do that, he wouldn't be able to add to the story as he would have to remain silent while the rest of the Avengers are running around completely confused by everything Percy and Jason do. If I can work him in later I will but for now I hope that clears up any confusion! Sorry for that long explanation. Hope you all enjoy the chapter!

He glanced over the side of the dragon to see the sea far below. Checking his navigation system, a grin grew on his face.

"Festus! Great news! Our controls are all messed up and we have no idea where we are!" he said, excitedly.

He could feel Festus giving him a confused, judgy look. "Creak?" he asked.

"It's a good thing because that means we're near Ogygia, and near Calypso!"

Another uncertain creak. Can creaks sound uncertain? This one did anyway.

"I am Leo Valdez. The McShizzle himself. Don't you trust me, oh faithful dragon of mine?" asked Leo, his chest puffed out in pride.

No response. "Hey! That's no way to answer your creator," scolded Leo. "Click click, creak."

"That's more like it," agreed Leo, sounding satisfied. "Now, let's head below the clouds and we should be able to see-"

Leo yelped as they began shooting down at lightning speed, breaking through the layer of fluffy white clouds, cheering out as the island came into view.

He realised too late that Festus wasn't slowing down, and soon he was getting a mouthful of sand as he made a crash landing, sending him flying through the air, doing multiple rolls across the ground before finally coming to a stop with his limbs bent in the most uncomfortable position. A less than graceful entrance.

His body contorted at a bizarre angle, he manoeuvred himself so he was lying on his back, blinking sand out of his eyes and spitting it out of his mouth.

When he pried his eyes open, he saw the silhouette of an ambered hair girl outlined by the sun, dressed in jeans and a white blouse, staring down at him with her hands on her hips and an unimpressed expression on her face.

She raised an eyebrow at him. "Ta da?" tried Leo, putting on his most dashing smile.

"You're late," she announced.

"Fashionably," clarified Leo, pulling himself up. He brushed himself off and he looked up at her. Their eyes met.

They stared at each for no longer than a moment before she pulled him into a kiss, which Leo gratefully received and returned.

When they pulled apart, she had a small smile on her face. Leo grinned. "I knew you missed me."

She rolled her eyes but still held her smile. "Don't make me regret it."

"Shall we make ready to depart then?" he asked, taking her hand and bowing chivalry.

"Absolutely," she agreed, stepping beside him so Leo had a view her waiting luggage. "You have enough stuff there?" he asked, laughing slightly.

"Well, I'm definitely not coming back here, so everything must be taken in one trip," she said, looking at the island.

"Fair enough. Well then, I shall set to work repairing..." he trailed off as he turned to see Festus limping around the beach, metal scorched and a missing leg.

"This might take a while," he said, scratching his head. "But don't worry, we shouldn't be here too long, seeing as I don't have all the equipment needed to properly fix him."

Calypso clasped his hand. "I've been on this island for many years. I can wait a little longer."

...

After only an hour, Leo had Festus at a stage where he could stumble them off the island, hopefully in one piece. (Both them and the dragon.)

"I hope you don't mind. I'd like to stop by camp before we head off anywhere. Should probably let my friends know I'm alive and all," stated Leo, as he finished up some final tweaks before stepping back and admiring his handy work.

"You didn't really leave them thinking you were dead, did you?" she asked, folding her arms. "What? No! I would never do that, the fact you would even suggest such a thing..." Leo looked over to see her staring at him with a deadpan expression.

"Well it wasn't my fault! I did die!" he defended, looking all pouty. Calypso rolled her eyes but smirked all the same. "Fine, fine, I'll accept your excuses for now," she sighed.

"Great! Are you ready to go then?" asked Leo, smiling at his victory, childish as it was. "Definitely," replied Calypso.

Leo stepped back and spread his hands in the direction of the waiting dragon. "Then by all means, climb aboard, m'lady," he said, charmingly.

Calypso giggled and stepped forwards.

Suddenly, a blinding light erupted before them, causing them to shield their eyes. Leo protectively placed an arm in front of Calypso to defend her from the oncoming danger.

When the light faded and their hands were removed from their eyes, a bearded man stood before them. A bearded man Leo recognised, with his grimy blue overalls and face covered in welts as if he'd been bitten by a million bees. Tool belt, not unlike Leo's, strapped round his waist.

"Dad," mumbled Leo, staring at the figure before him.

...

"They're going to die... you killed them... it's your fault... Perseus..."

Percy sat with his knees pulled up to his chest, his arms wrapped tightly around them. His eyes were wide as he glanced fearfully around the room.

The voices had been speaking for a while now. Percy knew they weren't there, but he still couldn't shake the trembling fear coursing through him, their words cutting deeper and deeper, sounding more and more true the more Percy heard them.

"You hurt them... and you're going to hurt them again... Percy..."

He closed his eyes, clasped his hands to ears and pressed his forehead against his knees.

"It's not true. They're not there," Percy whispered to himself. "They're not there, it's just the disease. They're not there."

"Percy...Perseus... Percy!"

"Stop it!" yelled Percy, finally having enough. "Leave me alone!"

The voices hushed. Percy pried his hands away from his ears and hesitantly peered around the room.

Silence. That actually worked? Really?

He was about to breathe a sigh of relief, when a shadow loomed over him. "You didn't think that was the end, did you?"

...

Jason sat anxiously at the bar table, tapping his finger against its surface. He stared ahead, chewing on his nail.

"Jason?"

Jason snapped to attention at the sound of the voice. He whipped his head around to see Bruce looking at him curiously.

"Yes?" he asked, hoping to seem nonchalant, despite his obvious anxiety.

Bruce frowned and sat down in the barstool next to him. "When I was with Percy, he said something to me rather concerning."

Jason gulped, wondering what Percy could have told him. Delirium might have set in, so he could have told him anything. Anything.

"Oh yeah? What did he say?" he asked, hoping the apprehension didn't come across in his tone.

"He made me promise to keep you as far away from him as possible," Bruce explained, watching Jason carefully.

Jason looked away. He's trying to keep me safe.

"He must still be mad at me," muttered Jason, steering from the truth. "I don't think that's the case," said Bruce. "And I don't think you do either."

Jason looked up and made eye contact with the man. "He was sincere, Jason, not angry," continued Bruce.

There was a pause as the two looked at each other, each searching the other for any trace of lie or truth.

"There's something you're not telling us," theorised Bruce, but it sounded like he knew it for a fact.

Jason felt a chill run down his spine as he stumbled for how to answer. "I-"

A yell rang out from somewhere in the tower. Everyone's head whipped round, staring in silence as they stopped what they were doing and listened.

Footsteps sounded distantly, but grew closer quickly, as if the person was running.

An agent appeared in the doorway, gun drawn. "We need your assistance," he said, looking to all the Avengers before his eyes landed on Bruce. "It's the kid," he said.

Jason stood up abruptly as his stomach dropped, feeling himself choke slightly from the shock. Percy? What was wrong with him?

Bruce's eyes widened as they quickly looked at Jason before his expression was replaced with one of professionalism and seriousness.

"Take me to him."

...

The group dashed out of the room and up the stairs, Jason in the lead.

What's happened to him? Has he gotten worse? Is he...

Jason did not allow himself to finish that thought, shaking his head as he pushed forward.

Once they arrived at the med bay, they all froze outside the window, staring in with pure horror.

Percy was thrashing around on the bed, screaming out like he was being tortured. As if he were in the worst pain possible. Agents were trying desperately to hold him down with much effort but to no avail.

Horror sank in as Jason realised immediately what was going on. What stage Percy was in. Agony of Tartarus.

Getting over the shock, Steve quickly walked to the door, the others following behind. Jason stepped forward with them, but Steve put out a hand to stop him.

Jason frowned accusingly at him. "What are you doing?" he demanded.

"You stay out here. We'll handle this," ordered Steve.

"But-" Jason tried to argue but the others ignored him and entered the room to assist the struggling agents.

Jason paced back and forth in front of the window, watching the whole time.

The Avengers managed to hold him down, but only for a brief moment. Percy kicked out and sent Clint flying back. He yanked his arms free of Natasha's grip somehow and was jerking uncontrollably. He was screaming the whole time.

Bruce tried to get close enough to have a look at him, but it was pointless. No one could get within a few feet of him without being attacked.

It seemed as though Percy didn't even realise they were there, zero recognition on his face anytime someone got close. Then a moment appeared where Percy focused on someone in front of him, and looked... scared. No, not scared, terrified. Like he didn't know who they were. Like they were some monster.

"Get away from me!" he yelled, anger clear in his voice but laced with fear all the same. "You can't keep me here!"

"Percy," tried Tony, but was interrupted fairly quickly by a fist flying out to meet his face. Tony only barely dodged.

That's it. Jason had had enough. He didn't care what happened to him. Percy needed him.

He hurried over and yanked the door open, dashing in.

"Everyone get back!" he ordered. No one listened though, too focused on the chaos.

He felt someone grab him and try to pull back out of the room. "Let go! I can help!" he yelled.

Another pair of hands grabbed onto his wrists, yanking them behind his back as Jason continued his struggle. Just when he thought he would be taken out for good, Steve stepped in.

"Wait," he said to the agents. He looked at Jason for a moment, Jason's eyes pleading with him. Steve turned his attention back to the two agents holding him. "Let him go."

They shared a look, peering at Steve sceptically. "Are you sure?" the woman asked. Steve nodded. "I'm sure, please wait outside," he ordered.

After a moment's hesitation, they released Jason and exited the room, rather begrudgingly.

Steve turned his attention back to Jason. "Can you help?" he asked, seriously. Jason nodded. "Yes," he stated, firmly.

Steve nodded, and gestured to Percy, who the others were still struggling to get a hold of and contain.

Jason ran forward, up near Percy's face. His pupils were dilated and unfocused. "Let him go, and get back," he demanded the others.

"What?" asked Tony, looking at him like he was crazy. "I can help, now all of you get back," Jason said again, leaving no room for argument.

The Avengers glanced between each other, then to Steve. "Do as he says," ordered Steve. They all stepped back.

Jason moved forward, putting his hands on Percy's shoulders. If he didn't calm him down soon, he was going to hurt himself as well as everyone else.

"Percy," said Jason, trying to get his friends attention. But Percy wouldn't even look in his direction, instead looking everywhere else like he was being attacked by the room itself.

"Percy!" Jason said, louder. Percy's head whipped round to him, his eyes latching onto Jason's face and staring at him in horror. Jason didn't know who or what exactly Percy was perceiving, but it definitely wasn't good.

"I don't know what you're seeing right now, Percy, but it's not real. Okay? It's me, Jason," soothed Jason, trying to sound calm.

Percy was still panting, breaths shaky and fast, and Jason recognised the look on his face; the same look he had when he escaped...

"Percy," Jason said again. "You're not there. You escaped, both of you, and you never have to go back."

Percy's breathing began to slow, and his pupils appeared to shrink back. Awareness seemed to return to his expression.

"Jason?" he whispered, voice raspy from screaming. "Yeah buddy, it's me," assured Jason.

"It hurts," Percy said, voice strained. "What does?" asked Jason, quietly. "Everything," replied Percy, sounding extremely weak.

Jason grimaced and turned away for a moment, before taking a deep breath and looking back. He glanced at Bruce. "Do you have anything to help him sleep?" he asked, hoping he didn't sound as drained as he felt.

Bruce quickly walked over to a nearby drawer, taking out a syringe and medicine vial. He came over hesitantly and placed the needle into Percy arm, weary of another outburst. But Percy remained completely docile, not even seeming to notice Bruce's presence.

The drug seemed to take effect relatively quickly, as Percy's eyes began to close. "I'll see you when you wake up," reassured Jason, watching Percy as he drifted over.

Percy croaked a laugh. "I think we both know the odds of that are becoming pretty slim," mumbled Percy.

Jason shook his head. "Don't talk like that. You're gonna make it," said Jason, though after what just happened, any hope he had that Percy might survive this had dwindled to only a flicker. But the flame was still alive, if only barely.

He glanced over at the Avengers before leaning in closer to Percy.

"You are the strongest demigod I know," whispered Jason. "You have beaten more monsters than anyone ever has. You beat Gaia. You are going to beat this too."

He pulled back and looked into Percy's eyes. They held each other's gaze for a moment before Percy finally nodded. "Okay," said Percy. Then he smiled. "Can't let you outlive me, Grace."

Jason smiled in return. "Well when you put it that way..."

Percy laughed quietly before finally falling over.

Jason breathed in and closed his eyes. "Morpheus. Please. Let him sleep. Keep any dreams, or nightmares away. Please," he whispered in Latin, looking upwards when he finished. He knew communication with the Gods wasn't really working right now, but he hoped this prayer would at least get through.

Jason opened his eyes and watched Percy for another minute in silence, before standing up as emotions came flooding in, all in one go.

He sniffed, looking away from his friend. He heard someone take a step towards him.

"Jason?" asked Clint, hesitantly.

But before anyone could get a word in, Jason fled out the door.

...

Jason really had to stop running whenever something like this happened. It could not have looked good on his part. They probably kept thinking he was trying to escape, and they definitely were becoming suspicious, as implied by Bruce's questioning earlier.

He returned to the lounge area to collect himself and catch his breath. He was panting, which was weird considering his usual high level of stamina. Though it made sense, what with all the stress he had been feeling lately, and the horrific event he just had to endure.

He leaned on the bar table, head resting into his chest, eyes scrunched closed.

His hands were shaking slightly, but he didn't care right now. He's nearing the end of the stages. After that...

"Jason, there you are."

Jason opened his eyes and turned his head to the Avengers who had entered the room and were walking up to him, very worried looks coating their features.

"Are you okay?" Steve asked, sounding concerned. Jason had to resist the urge to roll his eyes. "Do I look okay?" he asked, irritation evident in his tone.

"What the Hell just happened back there?" Tony asked incredulously , gesturing vaguely in the direction they had come in.

"Nothing," Jason answered automatically. Clint slammed his hands on the table, taking everyone by surprise.

"Bullshit," he said angrily. "There is obviously something you are not telling us; something bad that is happening; with you, and with Percy. From what we just witnessed back there, there is no way you can try and say that nothing is going on. So, you need to tell us the truth, and you need to tell us. Right. Now," finished Clint, his glare hard enough to cut through ice.

The others looked briefly at the man in shock, before they all turned expectantly to Jason, who was at a loss for words.

He opened his mouth, hoping something would come out, but nothing did. So many things were going through his head he couldn't begin to think of an answer. He grunted and looked away. "I... don't know... what to tell you..." he started.

Clint through his hands up in the air in exasperation at Jason's attempt at the continued lie. Natasha folded her arms and fixed him with a look of, was that disappointment?

She shook her head. "I really thought we would be past this by now, Jason," she said lowly, before turning around and heading out the door. The others followed.

"Damn it," muttered Jason. They were at the door when something came out of Jason's mouth before he could even think to stop it.

"He's infected," he blurted out.

They all stopped and turned to look at him, eyes narrowed.

Jason took a deep breath. It couldn't wait any longer. Percy couldn't wait any longer. No turning back now. Jason looked up at them, looking at them each individually before continuing.

"He's infected, with a plague that's so deadly it's killed almost my entire camp in 5 days."
