This takes place during season one of YJ set in no particular episode just kinda floating around there.

I apologize in advance for the OOCness of Nico and Percy, but hey, it is an AU so...I also gave Percy a cool power that might come in handy in later chapters. Please feel free to comment on extra powers for Jason and Nico and I might add them into the storyline! :)

Percy was running. Reaching for a hand that was outstretched. He called out the owner's name but he couldn't hear his own voice. He screamed and screamed until he felt his throat go raw but still, he couldn't hear his own words. But he heard hers. Her last words.

'Percy…...take care of them. Hazel and Nico, please.'

Bianca's last words.

"BIANCA!" Percy sat bolt upright. His chest was heaving and he was panting but it was strenuous and he breaths were labored. It hurt and it was hard to breathe. He looked around the room he was in and took in the serene surrounding, the white walls, and the occupied beds to either of his sides. Upon closer inspection, he realized that Jason lay on one while Nico lay curled in on himself on the other. He went to get up but found that he couldn't. He winced and bit back a cry of pain as his chest flared up.

"I wouldn't try to move just yet Perseus. We dowsed you in some water but we had to wait for you to wake in order to give you some ambrosia. You have several broken ribs and I am afraid that the water only healed your scrapes and bruises." A silky voice rang from the corner of the white room.

"Di," he started, unsure of how to continue, "where? How…?" he trailed off and looked down at his feet.

"Relax, Perseus. You are among my allies. I trust them with my life, as should you." She smiled sweetly at him. "What do you remember?" She asked as she walked over towards him with a handful of ambrosia. He took it graciously and nibbled on it. He was silent for a while before he spoke.

"Bianca is dead, isn't she?" Diana didn't look surprised. She wouldn't, of course. She knew that her would be brother tended to have prophetic dreams. It was due to his godly lineage.

"It was a dream, wasn't it? What happened?" Percy nodded and looked into her eyes.

"She reached out to me and I called out her name….but I couldn't hear my own voice. I could hear hers though. As plain as day, you know?" Diana nodded along, patting his back in comfort and urging him to continue. "She asked me to….she asked to me to take care of Hazel and Nico...Hazel!" Percy yelled suddenly. "Where are Hazel and Thalia?!"

"Perseus, please calm down. You will only increase the damage to your wounds before the ambrosia has a chance to heal them." Percy couldn't hear her though. There was a ringing in his ears and his chest felt heavy. It was hard to breath again, not because of pain, but rather the anxiety he felt right now. Because of Percy's dreams he tended to have panic attacks due to the knowledge he gained from them. They had simply become a normality since then and usually Thalia helped him through them. How pathetic was he? A demigod, being bested by a panic attack. Percy began to hyperventilate when strong arms wrapped themselves around Percy's shoulders. He didn't need to look to know who it was.

"Jason.." Percy gasped out.

"Calm down Perce. I'm right here. Me and Nico are right here." Percy looked around and saw that Nico was sitting up on his bed, digging his fingers into the sheets, and looking at Percy with expectant eyes. "Are you okay now?" Jason asked.

"..Y-yeah, I'm fine." He looked back at Diana who turned to walk out the door, saying that she would be right back. Percy gave some of his ambrosia to Jason and then turned towards Nico. "Neeks, do you know where Hazel and Thalia are?" Nico's eyes started to well with tears but he wiped them away fiercely.

"They were taken. I tried to help, I really did! But - those guys-"

"Klarion," Percy said with hate, "and-"

"Deathstroke." A new voice said. The three boys turned to see a man in black bat-shaped armor standing in the doorway next to their pseudo-big sister. "Two members of the Light. An evil organization hell bent on ruining the universe." When Percy and Jason just stared at him, he continued his explanation. "Your cousin Nico told us everything when Diana brought you all to the Mountain."

"The Mountain?" Jason asked quizzically.

"It is a base of operations for a covert team of young heroes, Jason. They work under the Justice League."

"Dad used to tell us stories about you working with them all the time…." Percy said happily then his smile faded when he remembered the events of the past couple hours. "We never should have left. I should have told Thalia is was a bad idea." Percy yelled at himself in anger.

"No, Perce. It was just as much my fault as it was everyone's. We all should have opposed. Dad and uncle Poseidon and uncle Hades told us that the mortal world was not kind to demigods and we didn't listen."

Percy's eyes trailed around the room and spotted another bed hidden behind a curtain. He got up and walked towards it. As he got closer, he noticed that a sheet covered whatever was laying on it. When his hand nearly reached it, it was suddenly grabbed by the man in black. Percy never looked away from the linen sheet, but also never fought against the man's hold on his wrist.

"It's Bianca." It wasn't a question, but rather a statement and the man in black confirmed it with a grunt and let go of his wrist. Percy guessed that the man didn't want him to see the mess that was Bianca's dead body. He stood there for a while and the silence was only broken by the door sliding open once again.

"Bruce, we're back!" A black haired boy bounced through the open door only to stop in his tracks at the sight of the strangers. "Oops." Bruce sighed and took off his cowl after closing the door.

"Diana trusts you, so I do as well. My name is Bruce Wayne, also known as Batman, and this," He gestured to the black haired boy, "is my son, Richard Grayson-Wayne, known as Robin. I tell you this because I trust you all. Very few people know our true identities so I trust that you will not tell anyone." When Bruce gained nods from the three teens, he out his cowl back on and gestured for them to follow him out of the room.

"So, you know my name but what are yours? And who are you? How do you know auntie D?" The kid, Richard - no, Robin, asked them.

"I'm Percy, this is Jason, and this one is Nico, Neeks for short." he said, ruffling the boy in question's hair much to the younger's chagrin.

"I do not know why you don't go by your full name Perseus. It is a splendid name for such a fine warrior as yourself."

"Perseus? Your name is Perseus?" Robin laughed while holding his middle.

"I prefer Percy, if you don't mind."

"No problem, Percy. You can call me Dick when no one else is around. Except for Wally, he knows my ID because he's my best friend. You'd like him." Now it was Percy's turn to laugh.

"Man, and I thought my dad naming me Perseus was bad."

"Speaking of, who is your dad? Is he a hero like you? That's why you're here right? To join the team?" Dick asked as they were coming up on the next room.

"Not exactly. Diana helped us out of a pretty sticky situation and now we're just trying to figure out what to do from here. As for my father, he's Poseidon, god of the sea." Percy continued walking as Dick stopped in his tracks. As the group entered the luxurious room, they could here a high-pitched 'so cool' from down the hall.

Percy, Jason, and Nico followed Batman and Diana into the middle of the room where a few adults and a group of teens were gathered. Batman stepped forward and spoke loudly.

"Team, it has come to our attention that the Light has acquired a few powerful beings and at the behest of a higher power we are to assist these three," he gestured towards Percy, Jason, and Nico, "in getting them back."

"Who are they and who is this 'higher power'?" A red haired boy with bright green eyes questioned. Batman motioned to Diana and she then stepped forward to introduce her kin.

"This is Perseus-" Percy coughed and Diana had to stifle a snicker, "Percy, Jason, and Nico. They are the children of Poseidon, Zeus, and Hades respectively. They are demigods by title and their godly parents are the 'higher power' you asked about Wallace."

As Diana's words sunk in to the others, a dark skinned boy voiced a concern.

"Who are the two who were taken by the Light?" At the boy's question, Nico's eyes began to tear up again and a blonde girl whacked the boy upside the head. "I apologize, I am Kaldur'ahm, but you may call me Kaldur. I did not mean to upset you." Nico shook his head and grabbed onto Jason's arm.

"It's fine it's just that if that weirdo with the cat hadn't of attacked my sister, there would be three captives and not two." The team was speechless as they listened to Nico.

"Bianca and Hazel are Nico's sisters. Bianca was killed by Klarion. Thalia, Jason's older sister, was captured by Deathstroke and the other man." Percy finished.

"We will begin working on a plan tomorrow, right now, I suggest you get acquainted with each other and get some rest. You've been through a lot." Batman said, and he turned to leave. Diana ruffled each of her brother's hair and also left after promising to come get them in the morning.

The boys followed the team to the lounge and exchanged things about each other since they would be working together to save Thalia and Hazel.

Elsewhere, at the Light's headquarters, Thalia and Hazel woke up in a damp a dark cell.

"Thalia, I'm scared." Hazel said as she clung to her older cousin.

"Shh, it'll be alright. Father and the boys will do something. I'm sure of it."

"But Bianca - she…"

"I know. I know."
