A/N: Alright, new story. This takes place after the war with the Giants, the potential war with the Romans, Tartarus, all that. I am saying that it is around late August the year after Percy went missing. I realize that there is a lot of dialogue here, and it is not my cleanest writing, but I had a blast writing it anyway, so I hope you can still enjoy reading it.

Let me know if you think I should continue or leave it as a one-shot

Paul watched Sally nervously pace back and forth in the lobby of the Empire State Building. He sat in a brightly decorated office lounge on the fifty first floor of the building, where he and Sally had been led as soon as they walked into the lobby. Paul sat in a plush green chair on the edge of the lounge by the door, gently rocking the stroller next to him as he impatiently waited for the doors to open again. He was surrounded by several unfamiliar faces, parents of the other demigods on the quest. As he waited, he thought back to the call that brought them here.

Paul had been just about ready to leave for work when the phone rang. Sally was deeply engrossed in the baby she held in her arms, so he rushed to answer the phone himself, hoping the call wouldn't make him late.

"Jackson-Blowfis residence," he stated as he picked up the receiver.

"Hello, is this Mr. Paul Blowfis?" the voice on the other end asked.

"This is he," Paul sighed. The guy didn't sound like he meant to be quick. Now, he was going to be late. He should have just let the phone ring.

"Hello Mr. Blowfis. I apologize for taking up your time," the voice responded as if he knew what Paul was thinking, "but I must confirm some matters before I continue speaking. If my information is correct you have been told about the gods by your wife and step-son?"

Whatever Paul expected the man on the other end to say, that was not it. "Um, y-yes. May I ask who is calling?" Paul asked suspiciously.

"My apologies, Mr. Blowfis, this is Lord Hermes, messenger of the gods, calling from Olympus. I am calling to request your and your wife's presence at the Empire State Building. We have a group of demigods recently back from a quest. One of whom is Percy Jackson."

Paul froze for a moment. Then he cried out, "Sally! Sally! We have to leave now! Percy is back!" I guess I am not getting to work at all, was his last full thought before he felt his mind scatter, running in a thousand different directions a million miles a minute. After a moment, he turned his attention back the the man, the god, on the phone, "We will be right over, Lord Hermes."

A voice cut through the tension in the room, pulling Paul out of his recollection. "Ma'am," the man who sat across from him called to Sally, "I am sure the children will be down soon. You should sit though. You look exhausted."

The man wasn't wrong, Sally looked almost dead on her feet. She looked like she was about to protest, but then just sighed and say down on the opposite side of the stroller. She looked down at the baby girl who slept peacefully in it, oblivious to the anxious air around her.

Sally looked back at the man. He did not look so good himself, pale and shaking a little. Sally pinpointed the problem almost instantly, "You are new to the whole Greek gods thing, aren't you?"

The man gave a raw little laugh, "That obvious, huh? Yeah, I just got a call saying that my daughter was the daughter of a goddess and on her way back from a war..." He trailed off and made a small distraught noise, putting his head in his hands. When he looked up again, he stood up and walked over to Sally and Paul, shaking their hands, "Tristan McLean, nice to meet you."

"Sally Jackson and Paul Blowfis." The man then turned to the other couple in the room, shaking their hands as well.

"Fredrick and Helen Chase," The blond man stated. He gestured to the twin boys who sat next to them, whispering quietly, "And this is Bobby and Matthew. They aren't normally this quiet." Fredrick turned towards Sally, "Jackson as in Percy Jackson?"

Sally smiled crookedly and responded, "Chase as in Annabeth Chase?"

Fredrick returned the smile. "I owe your son a lot, he has saved my daughter countless times."

"Well, the same goes for Annabeth. I am pretty sure Percy never would have made it where he is today without her."

Fredrick nodded in acknowledgement, then gestured to the stroller, "Annabeth never mentioned that Percy had a little sister though."

Sally looked down and sighed, "That's because Percy doesn't know that he has a sister."

"What do you mean he doesn't know?" Tristan asked.

Sally tried to answer, but realized she couldn't without crying. Paul answered for her, "When the gods saw that Gaea was rising, Hera took the leaders of the camp for Roman demigods and the camp for Greek demigods, wiped their memories, and dropped them in each other's camps." Tristan nodded like he knew this, so Paul continued. "Percy is the leader of the Greek camp. He has been gone for almost a year now. Sally found out she was pregnant just a few weeks before he was kidnapped. She planned on telling him when he came back from winter break. But... well, he never did." Paul gestured to the baby, "Hayley was born just under a month ago."

"Ah," Tristan murmured. "That's why you are so nervous then? You are worried about how Percy will react to a new half-sister."

Sally nodded miserably, "I should have told him as soon as I found out."

Helen, Annabeth's step-mom, reached over and patted Sally's hand. "I wouldn't worry about that too much. I met Percy when he was over in California to rescue Annabeth a few years ago. He seems like the sweetest kid."

"Thank you for saying that, Helen."

Just then, the door opened and all heads in the room whipped towards it. A man with black hair streaked with white walked into the room. He was wearing a suit, but on his feet were gym shoes... with fluttering wings coming out of the backs.

He cleared his throat, "The Olympian council has concluded. The Seven of the Prophecy will be down shortly," and he whisked out of the room.

Sally couldn't help noticing that their were only parents for three of the demigods. That meant four of them didn't have anyone.

When the door opened again, two girls walked in. The one with copper skin and choppy hair was supported on one side by a younger girl with gold eyes and darker skin. There was a heavy looking cast on her left foot. "Oh, Piper," Tristan breathed, standing up. The girl looked up at him and her eyes lit up at the sight of her father. She let go of the other girl and hopped all the way across the room to crush her father is a tight hug.

A blond boy walked in a few moments later. He walked over to Tristan and introduced himself. The girl who came in with Piper turned to Sally and Paul. She stuck out her hand. "I'm Hazel. The others are coming down. I think all of us are in various states of happiness and shock that it's all over."

Sally nodded understandingly, and watched as a thin, lanky boy walked in with grease smeared on his hands, followed shortly afterwards by a bulky boy who hugged Hazel before they all turned to watch Piper introduce the blond, Jason, to her father as her boyfriend. They watched with fond smiles.

It seemed like ages, but eventually, the door was thrown open again, and Sally started crying right then. Supporting a familiar blond with a foot that matched Piper's was a young man with the most brilliant green eyes and crooked smile. He led Annabeth to a couch, where she sat surrounded by her family. Then he turned back to his mom.

For a moment, neither of them moved, only stared. It was hard to believe that after all this time, he had made it back safely. Sally noticed that his skin was littered with more scars than before, and that he looked terribly bedraggled, but he was her boy and she was just happy he was alive. Eventually, he came forward and he hugged her tightly. After a few moments, he turned to Paul and hugged him too. Paul wasn't expecting it, so he stumbled, but hugged him back once he got his balance again.

Percy pulled away and looked like he was about to say something, but his eyes landed on the stroller. What ever he meant to say died in his throat. Sally suddenly got nervous all over again. How was he going to react?

Her son took a few steps towards the little green buggy, and stared down at the little girl inside. When Sally peeked over the edge, she saw that little Hayley's blue eyes were open, staring curiously at the new face staring back at her.

Percy looked up at his mom and back down at the baby and back up at his mom again. "When?" He asked. His voice sounded strangled.

"I found out in the end of November, three weeks before you left for winter break. I was going to tell you when you got back, but... Anyway, she was born a little early, on August 3rd."

He gestured to the baby, "May I?"

Sally was a little startled that he felt the need to ask, "Of course, sweetie."

Percy reached down and picked up the small child. He couldn't help noticing how his scared, war-roughened hands looked ever worse when placed next to the little baby's perfect pink and porcelain skin. Before he even knew what was happening, he felt tears start streaming down his face.

Sally watched her son with concern. He kept his eyes on the baby in his arms as he choked on his words, "I can't believe I missed this. I am so sorry, baby. So, so sorry." He looked up at Sally and Paul, and her heart broke at the distraught expression on his face. "I am so sorry," he repeated.

Hayley reached up and grabbed the collar of his shirt. Percy let out a strangled laugh.

Annabeth hobbled over, and looked at the baby in his arms. "Percy's a big brother? Gods help that child," she laughed.

"Hey!"

Sally was content to stand by and watch at this point. Percy surprised her, being more upset that he missed the whole beginning than upset about having a new addition to the family. In fact, as Sally watched her son, surrounded by a group of friends fawning over the new baby, she was confident enough to say that having the baby made Percy quite happy. He just came back from a war, and by the looks of him and his friends, it was harder than the last. Maybe having some new life will even help him heal.

Review! Let me know if you think I should continue this. It could stay as a one-shot, or I could write a few more chapters.
