Alright, here is the beginnings of some of the reunions. It's not all of them, as this chapter is already plenty long with just a few. I hope you like it. This is kinda uncharted territory for me, as this isn't really taking place in the context of one of the books. It's in the time gap between the two.

Note: If I don't specify a POV, it's Percy's.

Percy woke just after sunset. He looked around the room he was in. It was the med bay on the Argo II. He felt something on his arm. He looked down, Annabeth was asleep in a chair next to his bed, holding on to his arm. She looked so peaceful sleeping.

Not wanting to wake her, he slowly slid away, letting her hand fall onto the mattress. She mumbled something in her sleep. He smiled, kissed her on the cheek, and left for the deck of the ship.

He walked out onto the deck and instantly noticed the stars. The moment he did, he had to fight back tears. Bob had wanted him to say hi to the stars for him, so now was the time.

He sat down on the deck and leaned against the mast. He looked up and saw Zoë's constellation.

"Hi Zoë," he said. "It's been a while, huh? I saw you, down in Tartarus. Or rather, I saw a vision of you. You blamed me for your death. I guess in a way, I kind of blame myself too. I lost a lot of people along the way, some of whom I should have been able to save. If I had just fought a little harder or been a little smarter, they might be here today."

A cold breeze blew across the deck, making him shiver. "But anyway, I promise that's not gonna happen anymore. I'm a lot stronger now. I think now I finally have the power to make things right. I wish you could have met Bob. I think he's actually your Grandfather, but he doesn't really remember that part. He got a second chance, and he saved me. I promised him I would say hi to the stars, and you're the only one I can really think to say hi to."

He shuffled when he heard someone. It sounded like Annabeth. She was calling out for him.

She burst out onto the deck, her eyes wild and afraid. When she saw him, a whole mix of emotions flashed across her face. Recognition, relief, anger, back to relief, concern. She walked over to him.

"Percy. Why did you walk away? Do you have any idea how scared I was when I woke up and found that you weren't there? I thought you disappeared again."

He looked at the ground. "I'm sorry. You just looked so peaceful sleeping; I didn't want to wake you."

That mollified her somewhat. She moved to sit next to him. "It's ok. I was just worried. I still am, you really should be lying down."

He shook his head, "No that's ok. I can't really sleep. Besides, there was something I had to do."

She looked at him oddly. "What's that?"

"Oh, nothing. Don't worry about it."

"Percy." She gripped his arm. "Please, talk to me. I love you."

He sighed. "I love you too Wise Girl. It's just…" Another sigh. "I don't really know HOW to talk about it."

She smiled. "Just start, I think I can follow along."

"Ok, well. Do you remember when I told you about the Sword of Hades?" She nodded. "Ok, so there was that Titan that got his memory wiped by the Lethe. Well, he became friendly after that, we called him Bob. And when I was in Tartarus, I ran into Arachne." Annabeth paled when he said that. "We fought, and she was going to kill me, but out of nowhere, he jumped down and killed her."

His eyes started watering at the memory of Bob. "He helped me. He guided me throughout Tartarus. He saved my life more than once. And when we finally got to the Doors of Death, he stayed behind to make sure that I made it. I left him behind." Percy was crying now. "He forgave me when he found out that I was the one who took his memories. I never gave him a second thought after that, but he still considered me his friend. And I left him. I abandoned him in the worst place on Earth. I just…" He couldn't keep talking. He was sobbing.

Annabeth held him as he cried. "It's ok, Percy. You did what you could. You didn't mean to leave him."

"But I did!" Percy sobbed. "I left him. How could I do that?"

She continued to hold him. "It's ok, Percy." She said it over and over again.

Eventually he calmed down enough to talk a bit more. He breathed deeply. "I came up here because Bob loved the stars. He told me to say hi to them. It was one of the last things he said to me." He looked at Zoë's constellation. "I also wanted to talk to Zoë. I had a vision of her down in Tartarus. She blamed me for her death."

Annabeth shook her head. "That wasn't your fault."

"But it was. She died because I wasn't strong enough. So many people died because of me."

Annabeth hugged him tighter. "You can't blame yourself for that Percy. It's a miracle you survived. You didn't kill them. You always fought your hardest, that's all anyone can do."

Percy sniffled and nodded. "You're right, as always." He leaned into her. "I missed you Annabeth."

She hugged him even tighter. "I missed you too Percy. I was a mess for a long time after you fell, sick with worry. But it's ok, we're here now. We're together. You made it back."

She continued to hold him. "You're ok. You're back." She said these words over and over as Percy slowly began to fall asleep again.

(Annabeth POV)

This was so much worse than she could possibly have imagined. She had seen it when she laid eyes on Percy. But now that she heard him talk, and saw him cry, she realized just how broken he truly was.

He had literally been through hell. He hadn't even begun to scratch the surface of the things he had seen, and already she could tell how much of a toll it had taken on him.

He was curled up on the deck, head in Annabeth's lap. He slept fitfully and woke many times. Every time he woke up, he looked around in panic. In his sleep he muttered Bob's name over and over again. Every time he woke up in panic, she would hold him and whisper that she was here for him.

But the truth was, she had no idea what she was doing. She had no idea how to help him. Nico might, but he, Reyna, and Coach Hedge had left with the Athena Parthenos while Percy had slept.

And so, while he slept, she cried. She cried for the helplessness she felt. She wept for him; someone had broken her Seaweed Brain. She cried and cried until she had no tears left. But she made sure he never saw her tears. She had to be strong for him. He needed her, and so she would be there for him, even if she had no idea what she was doing.

(Frank POV)

He found Percy and Annabeth on the deck around sunrise. Unlike the last time he found the two of them together, there was no panic. He saw the two of them together and he smiled. He had watched Annabeth torture herself their entire journey from Rome. Now, he saw her leaned against the mast, Percy's head resting in her lap. She was awake, running her fingers through his hair, a slight smile on her face.

After seeing her in pain for so long, Frank felt nothing but relief seeing her smile. But they were supposed to have a crew meeting at breakfast. So, he approached them.

When Annabeth saw him, she smiled and put her finger to her lips, warning him not to wake Percy. She definitely had a point. Yesterday, Percy had been a wreck. He had had a panic attack just by seeing the sun. It was good to see him sleeping somewhat soundly.

As he got closer, Annabeth spoke very softly. "Hey Frank, what's going on?"

"I was just coming to check on you guys, we were going to have a crew meeting at breakfast, but I can just fill you in later. You should stay with him."

"No, no." She carefully slid out from under Percy, softly resting his head against the deck. "I should talk to the others about Percy. He said some things last night that have me worried. I think we are all going to have to be very careful around him. I don't know what might trigger him."

"Ok, well then let's get going."

"Actually, um." She shifted nervously. "I don't want to wake him, but I also don't want to leave him by himself. Would you be ok watching him? I can tell you about everything later."

"Yeah, that's not a problem. I'm happy to watch over him."

He sat on the deck and leaned against the railing of the ship. Annabeth thanked him and went off to the mess hall to talk to the others.

As he sat there, he studied Percy. He was different. His skin was definitely paler from lack of sunlight. He had a grey streak in his hair. But at the same time, in a way he looked surprisingly healthy. Frank would have expected him to be malnourished and thin, after all, Nico had been. But instead, Percy looked strong. In fact, he looked more muscular than before.

He studied the dirt and dried blood all over him, the shredded T-shirt under his Drakon hide tunic. He had seen Percy's new bone swords when he and Annabeth had laid him down in the med bay. Looking at all of that, Frank began to wonder just what things Percy had had to face to end up like that.

How many battles had he fought to look so disheveled? How much blood had he spilled to end up covered like that? They had traveled for 18 days to get to the House of Hades, had Percy really spent almost 3 weeks in Tartarus by himself? How had he slept? Looking at him, Frank imagined he probably hadn't slept much at all.

Before he could think any further, Percy began to stir. He blinked at the sunlight shining on him, as if it were blinding. It was good there was a fair amount of cloud cover and morning fog.

When he was awake, Percy sat up. He looked around wild-eyed. "Annabeth?" His voice was scared.

"Hey. It's ok. She went downstairs to get some food. She asked me to watch you."

Percy blinked. "Frank? Is that you? What happened to you? You're so tall?"

Frank laughed, he had almost forgotten that when Percy had last seen him, he had still been short and chubby. "Oh, it was a blessing from Mars. It's amazing what the Gods can do, huh?"

Percy grumbled. "Yeah, amazing."

"What was that?" Frank couldn't really catch the tone.

"Oh. Nothing. Don't worry about it." Percy wouldn't look him in the eye.

"I'm not the only one who went through changes. You definitely have a lot more muscle than the last time I saw you, you're taller too."

"Oh, yeah, that was a blessing too I guess."

That took Frank aback. "A blessing? In Tartarus?"

Percy nodded. "Yeah. I jumped back into the Styx. It was the only way to be strong enough to survive."

Percy's courage never ceased to amaze him. "Wow. The Styx? That's crazy man."

Percy shrugged. "I did what I had to do to survive. There's nothing more to say." He definitely looked uncomfortable talking about Tartarus. Frank couldn't blame him really. "What about you? What did you have to do to get a blessing from Mars?"

Frank realized this was a good opportunity. Percy needed to be distracted. "Well, it started when Hazel met with Hecate…"

(Hazel POV)

"Anyways, I'm worried about him," Annabeth was saying. When they had met up to talk over breakfast, Annabeth had started talking to all of them about Percy. After seeing him yesterday, and especially after what little Nico had said about Tartarus, Hazel definitely understood her concerns.

Percy was probably the demigod Hazel respected and revered more than anyone. When she had gone to Alaska with Frank and Percy, Percy had been their leader, even though Frank was technically the Centurion. And that had been without his memories. Then, when they had traveled to Rome, Percy had brought all of the crew together. His personality had ensured that everyone worked together.

And now, this friend, this leader, needed help. He had been on his own in the depths of literal Hell.

"I don't think it is a good idea for a group of people to be around him. You guys saw how he reacted yesterday. I think more than two people talking to him at a time is going to overwhelm him again." Annabeth definitely had a good point. "That being said, I don't think he should be alone either. I think we should take turns watching him. But he's proud, so we can't tell him that that's what we're doing."

"Good idea Annabeth," Jason said. "So, are you going to watch him at night then?"

"Now wait a minute Jason," Leo shot up. "Don't you remember what Coach Hedge told us before he left? 'No two demigods in one room ever again!'" He said in a pretty good imitation of Coach Hedges voice.

Annabeth glared at him, and he instantly shut up. He looked pretty ashamed.

"No," Annabeth continued. "I don't think that's going to be necessary, Jason. After last night, it's pretty clear he won't be spending his nights in a cabin."

"What do you mean?" Piper asked.

"Well, I told you what he said about Bob. When I went out onto the deck last night, he was talking to the stars. I think he's probably going to spend his nights on the deck. When he did fall asleep again last night, he slept much better than he had in the med bay." Annabeth looked sad. "But I also don't think he is going to sleep much regardless. He's wound too tight. He only slept because I was there, reassuring him that he was safe."

"We'll take shifts," Annabeth continued. "Frank is watching him now; I can fill him in on all of this later. And if he talks about Tartarus, be careful, but also pay really close attention. I don't think he is going to tell us all about Tartarus at once. But I know him, it'll slip out in bits and pieces. Remember those pieces and tell everyone else. We all need to understand what he went through if we are going to be able to help him."

"I wish Nico were still here," Jason said. "He would be able to help him." Jason looked at her. "Hazel, Nico told you about Tartarus, right?"

That question made her really uncomfortable, "Um…a little. I promised him I wouldn't talk about it though."

"That's ok," Jason replied. "Maybe you should go to check on Percy and Frank. You know a little bit about Tartarus already, I think you might be the first person he opens up to."

"That's a really good idea Jason," Annabeth said. "Go on Hazel. Can you tell Frank what we talked about?"

She stood up, "Yeah, once I get the chance, no problem." She walked down the hallway towards the stairs.

When she got to the deck, she took a moment to enjoy the sunshine. There were a few clouds, but the early morning fog was starting to fade as the sun rose. She saw Frank standing at the railing of the ship, looking out over the water.

She approached him. "Hey Frank, how is he?"

Frank smiled and gestured at the water, "Take a look."

She looked over the side of the ship. There was Percy, floating in the water, easily keeping pace with the ship.

"What's he doing?"

Frank smiled, "I tried to tell him he needed a shower, but he didn't want to take one. So, I managed to convince him to at least take a dip in the water, I figured you know, being the son of Poseidon and all, the water would be good for him."

She couldn't disagree, Percy definitely looked more at ease than he had before. He looked almost calm, and for a moment, Hazel was able to convince herself he had never fallen into Tartarus.

"Well, since he's in the water and can't hear us, I should fill you in on what we talked about." She began to relay the information Annabeth had told her, as well as letting him know what the plan was with keeping an eye on Percy.

"Bob, huh?" Frank said. "That makes sense, even someone as strong as Percy would need help down there. I learned something you should pass on to everyone else. Apparently, Percy took a dip in the Styx. I don't really know what that means, but maybe Annabeth does."

"That means he has the Curse of Achilles." Hazel was very familiar with the Styx; it was the border to the Underworld after all. "It gives the person impenetrable skin and enhanced battle reflexes. It makes sense that he would risk that to survive."

Frank shook his head, "No, he didn't say Curse, he said blessing. When I told him about the Blessing from Mars, he said he was blessed by the Styx."

Hazel stared at Frank, "That's impossible."

Frank kept watching Percy swim, "I'm just telling you what he said."

"Ok, I'll talk to Annabeth about that later. Is there anything else he told you?"

"Oh! Yeah." Frank slapped himself on the forehead. "I can't believe I almost forgot, apparently Percy is a Greek AND Roman demigod."

"A what?" Hazel was thoroughly confused now. "How can someone be both Greek and Roman?"

Frank shrugged. "I don't know, he's just kinda been saying things, he doesn't really give explanations. There's a lot of it that he doesn't want to talk about at all."

She sighed, "I know, unfortunately, that's the stuff we most need to know about."

As they talked, Percy decided he had had enough swimming, so he shot out of the sea on a jet of water and landed on the ship. He had a smile on his face, a real smile. It made Hazel so happy to see him smiling.

"Whew," Percy said. "Man, real water. I missed that. I feel as good as ever."

"That's great," Hazel said. "I'm really happy to see you." Without meaning to, she stepped forward and gave Percy a hug.

Percy was thrown off for a second, but quickly relaxed and hugged her back. "Me too, Hazel. Me too."

Frank smiled, "Yeah, now that you're here, we can actually comfortably put this darn thing in the water again. Welcome back Captain Saltwater." He gave a mock salute.

"Oh, shut up Frank." Percy still had a smile on his face. "Hey, by the way, I had a question for you guys."

"Name it," they said together.

"Would you guys be willing to teach me Latin? I figured since I'm a Roman demigod now, it might be a good idea to learn it. I sorta learned it when I was a kid, but ever since I learned I was a demigod, it's been all Greek all day."

That was not the question she was expecting. "Oh, well yeah, we could teach you Latin. Right Frank?"

"Yeah, no problem."

The three of them sat together on the deck, she and Frank taking turns teaching Percy new words.

As they sat together, Hazel was able to pick up on some of the changes Annabeth had been talking about. The physical ones were obvious, but she was starting to notice the differences in his behavior. He was quieter. He didn't just speak more quietly; he spoke less often. He would be silent for a really long time during their conversation, as if he had forgotten how to talk.

He was also more tense. Even when he "relaxed", he was tense. When he smiled, the smile never reached his eyes. Before Tartarus, Percy was a joker, just like Leo. Percy was always quick with a joke or some stupid pun. That part of him was gone now. Percy was so much more serious than before. The boy that had fallen in at 17 years old now behaved like a serious grownup.

She and Frank also had to be careful in how they talked. They needed to respect Percy's silence. A couple of times, she and Frank started talking over each other, and Percy began to lean away from them. In those moments, he instantly clammed up and wouldn't talk for several minutes.

Things almost boiled over when Jason came out onto the deck. He came up to them smiling. He was so happy to see Percy; he didn't notice the change in Percy's behavior when another person joined the group. Percy withdrew visibly, almost recoiling from Jason when he reached out to him. When Jason realized they were teaching Percy Latin, he started talking to Percy super enthusiastically, and Percy actually growled at him.

She pulled Jason aside and started to fill him in on some things while Frank kept Percy company.

Once she was sure that Jason was informed, they went back to Percy. Then she left Jason with him and went back to the mess hall with Frank.

(Jason POV)

Jason was pretty nervous watching over Percy, especially after Hazel chewed him out. It was mostly just a problem of him being overexcited. When he saw Percy smiling, he just acted like everything was back to normal. The real issue was that Jason didn't have any frame of reference for what Percy was going through. He tried to think about Nico and his experience, but that just reminded him of their trip to Cupid's Palace. And that stressed him out, he had no right to betray Nico's trust by telling Percy about it.

He was actually relieved when Percy initiated the next conversation.

"Hey Jason, you know how to fight with a spear right?" Percy looked at him oddly.

"Um, yeah. Why do you ask?"

"Well, I was kinda hoping to learn how to fight with a spear."

This struck Jason as odd; Percy was an incredible swordfighter. He had almost killed Jason back in Kansas, and Jason had been training since he was a child.

But still, Percy was taking the initiative, so Jason was happy to go along with what he wanted to do.

"Yeah, but you don't have a spear."

Percy smiled and uncapped Riptide. "Watch this." He uncapped it, and instead of turning into a sword, it turned into a full-length bronze spear.

"Woah, how did you figure out how to do that?" Jason was really stunned.

But he realized the mistake he had made in his question when he saw the expression on Percy's face darken. His smile faded. "Don't worry about it," Percy said bitingly. He refused to look Jason in the eye.

Ok, that was something he needed to remember. Direct questions were off-limits. He cursed himself, Annabeth had said he wouldn't freely talk about it, what was he thinking? He should have known better than to just ask a question like that off the top of his head. If Percy showed new abilities or skills, it had to be something he picked up in Tartarus. That meant that asking about them was taboo.

Fearing an apology might make things worse, Jason just unsheathed his sword and concentrated on changing its shape. He had never tried it with his new weapon, but for some reason he was confident it would work.

It did, his sword grew into a solid gold version of the same spear Percy was holding.

Hesitantly, he began to show Percy basic stances for spear combat.

"Ok, so it's important to note that fighting with a spear is fundamentally different than with a sword. Sword fighting is fast-paced and aggressive. When you fight with a spear, you need to be calm and collected the whole time."

Percy nodded, "So sword fighting is like Ares, spear fighting is more Athena."

Jason laughed, "Exactly, Spear combat is more like chess. It's especially useful for when you are outnumbered."

Percy scowled, "I know that. Let's just get started."

Together, they began to go through some basic moves.

Percy was a natural. Jason would show him a move once, and within less than five attempts, Percy had mastered it. Within an hour of training, Percy was more adept with a spear than half the Roman legion. Not only that, but Percy refused to practice at half-speed. Jason would demonstrate something at half-speed, and Percy would instantly do it full speed.

After an hour, Jason didn't know how else to teach him.

"Um, do you want to try a sparring match?" He was starting to relax seeing how excited Percy was to learn.

Percy shrugged, "Sure."

They took their places and began to circle each other.

Well, there you have it, the first few reunions are underway. Next chapter will begin with a Percy v Jason duel. Should it get dark? Should Percy lose it? Let me know.

Also, please PM me or Comment with other things you want to see, especially with the remaining reunions.

I've been toying around with an idea I saw on Pinterest, about having Percy get Siren Powers because he doesn't want to keep killing. Should I integrate that into the story at some point? Let me know.

Hope you liked it.

Peace.
