Percy met up with Annabeth to go to lunch and was surprised to see a blue button pinned to her shirt.
"What is that?" he asked. Annabeth thought about it for a few seconds, wondering if she should tell him.
"I can only tell you if you agree to join," she decided.
"But what is it?"
"I'm not telling." Percy sighed in exasperation.
"Fine. I'll join. Now tell me what it is."
Annabeth smirked. "Well, we can't let just anyone join. I'll have to talk it over with the other girls," she explained and then walked off. Percy shook his head and walked into the lunchroom. He sat down at their usual table with Cleo, Emma, Rikki, Lewis, Ash, and Zane. Then Piper, Jason, and Luke joined them. Percy kept glancing at the door to see if Annabeth would walk in but she didn't. He heard laughing from a nearby table and turned his head to see Annabeth sitting there with a bunch of other girls all wearing blue buttons.
Percy walked over to Annabeth and asked, "What is this, some kind of cult?"
Annabeth looked up at him and pulled him down so he was sitting with her. "They agreed that you could join." Then she pinned a blue button on his shirt. It said, "LCFC" in black.
"What does that stand for?" Percy asked.
"Luke Castellan Fan Club," Annabeth explained.
Percy knitted his eyebrows. "Why are we in this? And why don't I get a fan club?"
Annabeth chuckled. "I helped them overthrow their former dictator so they wanted me to join." Percy was still confused but nodded anyway.
"Can we move back to our table before our friends get suspicious?" he asked. Annabeth nodded and said goodbye to the other girls.
Once they got back to the table, Piper eyed them wearily but no one asked any questions. Percy was glad about that. He didn't know what he would tell them if they did ask.
Over the course of the next few days, all of their friends joined the club. So at lunch, everyone was wearing a blue button except Luke. And he was thoroughly confused.
"Why do you guys all have those stupid buttons on?" Luke questioned. Cleo giggled but everyone else pretended like they didn't hear.
"Hello? I'm starting to feel left out here!" still no one answered him, so he turned to Cleo. "Can you tell me what you're all hiding?" She suppressed a giggle and shook her head. Luke threw his hands up in exasperation. Luke looked around the lunchroom and saw that every single person there was wearing a blue button. Even some of the teachers!
Luke walked up to the table where Annabeth had been sitting a few days earlier. A couple of the girls squealed.
"Can you guys tell me what is going on here?" he asked.
"We're your biggest fans!" a girl screeched. Luke looked confused. "I always have been your biggest fan, Lukey-poo." The girl stood up and Luke almost passed out.
"Kelli?" he breathed. The demigods all snapped their heads in Luke's direction.
"KELLI?" all the demigods screamed at once.
"Didn't we already kill you this month?" Percy sighed as he stood up next to Luke.
Kelli grimaced. "Well, I heard that Luke was back and I just had to see that!"
Annabeth clenched her fists. "How could I not know?"
"Oh, don't worry about it, daughter of Athena. We have plenty of Mist."
"Why are you here? You're working for Antaeus, aren't you?" Jason asked.
Kelli chuckled. "Oh, son of Jupiter. How little you know. We empousi will not be tied down to such small beings. No matter, I would say we should take this outside, for the mortals' sake. But when have I ever cared about mortals?" Kelli and a dozen other girls sitting at the table changed into their true forms. Cleo, Emma, Rikki, Lewis, Ash, and Zane ushered all of the mortals out of the lunchroom while Percy, Annabeth, Jason, Piper, and Luke pulled out their weapons.
All of the empousi snickered at them before turning to Kelli.
"So long, demigods!" Kelli waved before every single one of the demons burst into flames.
"They're all senior empousi?" Annabeth exclaimed, frantically running for the exit.
"We are going to be in so much trouble!" Piper yelled as they ran out of the doors of the school. The principal was waiting for them.
Percy turned to Piper and muttered, "When are we not in trouble?"
