Here's part five and six.

She paced back and forth across the room. After the sun had risen that's when people woke up but luckily for Alexis they were too tired to notice them. Leo barely made it to the dining room. The only one who was awake enough to pay her any attention was Annabeth. Naturally she said hi but then she saw Percy. Annabeth rushed to his side trying to wake him up. Now Annabeth terrified Alexis, there was just something in her storm gray eyes that made Alexis want to say everything she had done wrong. So when Annabeth turned around and stared at her that's when Alexis knew the true meaning of fear. "What happened to him?" Annabeth said. Alexis said everything that happened and stopped herself from saying her last name remembering what Leo told her. Alexis didn't even notice everyone else walking out to see what was happening. Everyone was scared for Alexis, they recalled what happened when Percy disappeared and was replaced with Jason. Sadly Alexis didn't know about this, all she knew was that Percy and Annabeth were going out. Under her breath Alexis apologized. "Sorry? That's all you have to say? You put him in such a state of shock he passed out. I knew it was unwise to bring you here. We should've left you in that mall." It would've been easier and less painful for Annabeth to have just thrown Alexis off the ship. With tears in her eyes Alexis looked at Leo and said. "How far away are we from the closest harbor?" Leo walked to the screen. "About twelve miles. Why?" Leo looked at her expectantly. Alexis didn't say anything. All she did was walk down to the stables, pick up her backpack and skateboard. While she was down there everyone left to eat breakfast leaving Percy alone on the couch. Alexis walked back up and saw Percy on the couch asleep. Even though she didn't know Percy that long he was still her brother. She walked over to him, carefully she took off her sliver necklace and she put it in his hand along with a note explaining everything. She walked onto the deck and to the back on the boat, little did she know behind her was a one way window and Leo was the only one watching. Alexis walked in front of the railing prepared for the cold, dark water beneath her. Leo stood up abruptly and left the dining hall. Everyone else thought he heard something wrong with the ship. Leo walked beside Alexis, calmly he said. "What are you doing?" Alexis looked at him. Leo had never seen a girl so sad. She seemed worse than Annabeth when she couldn't find Percy. She spoke calmly, clearly she had spent years covering up her emotions. "I'm leaving. You told me Annabeth was the daughter of Athena so she's never wrong. And when she says something is unwise she must be correct." A single teardrop glinted off her cheek. At this moment Leo got a good look at her. Her dark hair contrasted with her pale skin. Her green eyes weren't like Percy's, her were harder and darker. She was smaller than all of them. Even though Piper gave her an Aphrodite touch her skin was had dirt specked in different spots. He realized that Alexis was going to jump off the ship and swim back to Greece. "You can't leave." He said. Alexis walked in front of him and looked him in the eye. "Why? They don't want me here. Percy and Annabeth hate me. So I'm going to go back to Greece find a way to go to South America." Her shoulders dropped. Leo stepped back and she looked at him. He looked into her eyes, she had started to tear up. While she was wiping her eyes she muttered something about how she hated crying in front of strangers. She sat down. "You're not leaving. No demigod left behind." He helped her up and brought her inside. He took her into the commons area were Percy must have woken up and left. He set her down on the couch where he sat next to her. "I'm sorry." She said under her breath. He smiled. She didn't know why but his smile kind of annoyed Alexis. "Here I need to show you something." He stood up and walked to a room like Piper's at the end of the hall. But this one had just a twin sized bed, a dresser with a mirror above it, and a window that took up one wall that showed just the calm waters of the ocean. She looked at him confused. "What's this?" He smiled. "If you're going to stay with us you might as well have a room to sleep in. I wouldn't want you to sleep in the stables every night." She thanked him and set her backpack on the bed. She didn't realize that it was already getting dark. "You should sleep." He said. She nodded. "Goodnight Leo," she leaned over and kissed his cheek. "And thanks again." He walked out and shut the door behind him, he knew he was bright red.

No matter how much she tried Alexis didn't sleep that night. Her head was full of questions that she didn't want to talk about. She realized no one else besides Leo knew she was still here. By a force of habit she reached up to touch her necklace then she remembered she gave it to Percy. She grabbed her backpack and pulled out another necklace she kept at the bottom of the bag. It was a simple gold chain with a square charm. It wasn't even real gold. She took it from a jewelry cart on 22nd street. She was sitting on her bed with her legs crossed in front of her when someone knocked on the door. She looked at her watch, which she also stole, it was 2:16 am. Carefully she walked up and slightly opened the door. On the other side was Percy. His eyes were frantic they were darting around everywhere. When his eyes set on her he relaxed. He took her arm and hugged her. Alexis struggled her way out of his grasp. She looked at him confused. "What are you doing?" He reached out to touch her shoulder but before he could she pushed his hand away. Alexis stepped away from him. She was scared because no one had ever shown any kind of affection to her. He just noticed that. "I'm sorry. I was relieved to know that you were still here." Percy said. "Why?" Alexis said. "I mean you're my sister. I've always wanted a sister. Come on, we need to talk." Percy spoke in a calm voice. "About what?" Never in her life has Alexis ever been so confused. "Well," Percy said seeming just as nervous. "I need to know something about my sister." He smiled at her but she didn't smile back. Percy led her to the commons area. Where he brought her hot cocoa. They talked all night. He told her about his life. Her favorite story is when Annabeth had found him at Camp Jupiter and she flipped him. That was the first time in a long time that Alexis had laughed for real. She told him about her life too. He said when she had been a stowaway on that ship it was interesting. He said he had been on every kind of boat except for an actual cargo ship. The only thing that told them it was morning was Leo walking out of his room to check on the ship's status. "Hi Leo." Alexis said happily. That really woke him up. He hadn't heard her be actually happy before. So it surprised him. "Umm morning Alexis, Percy." They nodded at each other. Alexis didn't get why guys did that. She smiled and shook her head. Percy walked her to the dining hall since they were the first one's there they continued talking. He told all the things demigods should know from the story of Kronos to the fact they weren't supposed to use phones. Which she was fine with since she didn't have any friends. When people woke up and started to file in. Leo stop them from going in. When Leo walked away they walked in and were surprised to see Alexis and Percy talking like they had known each other for their entire lives. They all walked away, when Annabeth woke up she still believed that Alexis was gone and on her way back to Greece. So when she walked into the dining room to see Percy and Alexis talking. She was surprised but when she made Percy laugh the same way that he laughed when she made him laugh, she got mad. Alexis noticed her. "Morning Annabeth." Alexis smiled and walked out of there leaving Percy and Annabeth. Alexis walked past everyone in the common. "Morning everyone." She smiled and walked to her room.
