Percy, Annabeth, Piper, and Jason all went back to the house to get Luke, then headed to the beach. The mermaids were already there.
"Hey!" Cleo exclaimed once she saw them.
"So we wanted to tell you that our boyfriends know about us. And we want to know if you would consider telling them about yourselves too?" Emma questioned cautiously. The demigods glanced at each other.
"If something goes wrong we can always use the Mist," Percy whispered to the other demigods. They all agreed.
"Sure, why not?" So, Cleo texted Lewis to have Ash, Zane, and he meet them in the moon pool.
Then Cleo, Emma, Rikki, and Annabeth jumped into the surf, followed by Percy, and Jason, Piper, and Luke with air bubbles around their heads. Once at the moon pool, Percy dried everyone off.
"Annabeth! Why didn't you tell me you were a mermaid?!" Luke exclaimed.
"Because you didn't know anything about them so I thought I should wait," Annabeth explained, gesturing to the other mermaids. Suddenly they heard the sound of someone falling and some cursing. Then Lewis, Zane, and Ash joined them. They all were very confused.
"What are they doing here?" Zane asked.
Cleo glanced at Emma and Rikki before she said, "They know about us."
"WHAT?" Zane and Ash exclaimed at the same time. Lewis's mouth formed into a little O.
"They came to Mako during a full moon. Are you all mermaids now?" Lewis looked like he couldn't believe it.
"No. Just me," Annabeth explained. Zane looked like his head might explode.
"But, Luke. We need to explain this to you," Emma remembered. So they did. They told Luke all about Mako and the moon pool. Once they were finished, Luke looked mystified.
"That's crazy! Can I do it? I need a power," Luke joked. Annabeth rolled her eyes.
"Well I bet you could but we've never seen a merman before," Cleo explained.
"Plus, you're fine the way you are. I didn't do this to myself on purpose," Annabeth said. "But, Luke. We need to talk. Rachel spoke another prophecy."
Luke furrowed his eyebrows. "Prophecy? Who's Rachel?" Annabeth glanced down.
"She hit you in the head with a hairbrush once," Percy said, trying to make light of the situation. Luke gave him a confused look.
"What does that have to do with a prophecy?" he questioned.
"She's the oracle," Piper explained, not understanding what was going on.
Luke glanced at Percy and Annabeth. "What is she talking about?"
"Um. Sh-she passed the Spirit of Delphi into herself," Annabeth explained in a shaky voice. Luke looked like he didn't understand why she was so nervous.
Percy took a deep breath and elaborated, "Luke, she did what your mother tried to do. And succeeded."
