Percy jumped back and fell off the bench. He could hear Annabeth, Grover and Thalia shouting in surprise. When he sat back up he saw that Dick had begun backing away.

"Wait, where are you going?" Percy scrambled up and tried to walk towards him. With every step he took Dick took two steps back.

"I-I was just kidding. I don't know who my parent is!"

"But you said I was your brother!" His brother! That fact had just hit him hard. Hadn't Percy always wanted a brother. Sure he had Tyson, but he barely ever got to see him, not to mention that he was part cyclops. "Wait! Please, come with me, I can bring you to our father! You can meet him!"

Dick froze, then gave him an icy glare. "You can't prove that I'm HIS son, he doesn't even know I exist. My letter said that he never will!"

"What letter?" Percy asked, quizzically. Well that was surprising, he didn't even know Poseidon, but from his tone, Dick seemed to hate him with a fiery passion.

Dick hesitated, then turned on his heel and ran back to his father, no, adopted father?

"Bruce!" He tugged on the mans hand. "I'm feeling kinda tired, can we go home?"

Bruce glanced towards Percy and his friends. Although his smile seemed pleasant his eyes were cold and calculating giving Percy chills.

What the heck was up with the people of Gotham?

Bruce nodded towards Dick and the pair walked out of the park towards a large limo parked on the street.

"Did they just walk into a limo?" Grover asked, dumbfounded.

"So are we not gonna talk about what just happened?" Thalia said looking annoyed at Grover.

"Richard Grayson" Annabeth mumbled. "Bruce... Bruce Willis? No, Bruce Tremone? No."

"What are you mumbling about?" Thalia asked.

"BRUCE WAYNE! Billionaire, playboy philanthropist Bruce Wayne! Fostered a son Richard Grayson, after his family, a group of trapeze artists was murdered last year."

"How did you figure that out?" Percy asked.

"Don't you watch the news, seaweed brain?"

"Honestly, not really. I'm surprised you do!" This earned a glare from Annabeth. "But considering it's you, wise girl, I guess I shouldn't be surprised."

"If you two are finished flirting we need to find out what to do!" Thalia groaned.

"First I need to speak with my father. He never told me he had another son." Percy paused deep in thought.

"Dick said that Poseidon didn't know he existed, but how is that possible?" Grover asked.

"Yeah, I mean sure the gods can't see what happens in Gotham, but the kid's only been living here a year. Wouldn't Poseidon have been able to sense him?" Thalia added.

"We'll have to see what he says." Percy said looking east towards the Gotham harbour. "I'll have to swim out of Gotham for him to sense me."

"Do your thing!" Grover said.

"And be careful." Annabeth smiled giving him a peck on the cheek.

"Aww you do care!"

Suddenly Thalia smacked him upside the head. "Just make it quick please! I don't want to spend another hour in this city."

Thirty minutes later Percy was underwater calling out for his dad.

"Dad! Please this is important! I need to talk with you now!" No answer. "It's about something that happened nine years ago, with someone named..." what had Annabeth told him before he left. "Mary Grayson?"

At first Percy thought nothing would happen when suddenly foam was swirling around him and he found himself standing on mount Olympus. His father sat in front of him on his throne, a troubled look on his face.

"Mary Roustine. That's a name I haven't heard in a long time."

"But I thought it was-"

Poseidon's face hardened. "John Grayson was... Not important. Where did you here this name? Have you, have you met her? Is she in Gotham? That must be why I couldn't sense her all these years." He smiled sadly lost in thought.

Percy stood awkwardly. He'd thought his mother was the only one Poseidon thought about.

"How, how is she? Mary?"

Percy took a deep breath then looked down. "She's umm, well, I mean."

"Percy?" Poseidon asked hesitantly.

"She's dead."

Silence.

Percy looked up. Poseidon looked shocked, wounded, he was staring straight through him now.

"Umm, So is her husband. And her sister in law, and her nephew."

More silence.

"Her step brother's still alive, but uh, he's in a coma, and paralyzed for life." Percy cringed as he relayed the tragic events Annabeth had relayed to him.

"No." Poseidon whispered quietly. "I never, I never got to apologize." He looked down sadly.

Percy wanted to ask what he'd done, but there was one more thing he had to say. "Her son is still alive."

Poseidon's head snapped up towards him.

"Your son." Percy said weakly. "My brother."

Poseidon's mouth was opening and closing like a fish out of water. "That's- that's impossible. I would have-." He put his head in his hands. "I should have sensed him."

"He said he had a letter, a letter saying that you would't find him." Percy said

"From his mother, I presume." He said sadly.

"What do we do? I can't just leave him here, but he made it pretty clear that he didn't want any part of, this." Percy gestured towards himself and everything else in the room.

"He is a part of the prophesy is he not?" Poseidon asked.

"Find the bird who lived in the city of death." Percy mumbled. "I guess he was one of the only survivors in his family, but why call him a bird? Either way, yeah, I'm pretty sure he's a part of the prophesy."

"Then do everything it takes to bring him with you." Poseidon paused in thought. "I-I would like to meet him. Bring him to camp half blood and I will meet you there."

Percy nodded and shifted awkwardly. "See you then, I guess."

Poseidon got up from his throne and wrapped his arms around Percy in a hug. Percy took a small step back at the unexpected action, then returned the hug.

"Be careful my son." Poseidon whispered.

Before he knew it he was back in the ocean. When Percy emerged from the water to confront his friends he gave them a dangerous smile.

"Oh no, I already don't like where this is going." Annabeth said, pinching the bridge of her nose.

"I know what we have to do!" Percy declared with a glint in his eye. "We have to kidnap Richard Grayson!"
