(Okay, this is just an idea I had last night while eating dinner at a Mexican restaurant, while reading FanFiction on my smartphone…so here it is. If you like it, review/leave a comment to let me know if I should continue with it.)

ALLY:

"Allyson Dawson? That's your name, isn't it?" A girl holding a pencil, and a baseball cap, stepped from the shadows of the dark music room. "My name is Annabeth Chase."

Ally was assuming to just come to Sonic Boom, turn the power back on—after that nasty electrical storm earlier tonight—and text Trish to tell her she was coming back over, after she called her dad. He had woken her up at Trish's, where she was sleeping over, and told her about the electrical storm—lucky for her, Trish's dad and JJ had built a backup generator for Wilderness Scouts, and her and Trish had already been sleeping with the lights out, so she hadn't noticed—and asked her if she could please go to the store, and turn the power back on. She had hastily agreed, but already she knew it was a bad idea.

"Please leave. Now. Just don't hurt me. You can even have my chicken fingers!" Ally tossed her purse to Annabeth, who crouched down to the purse, and threw it back to her.

"Listen, don't be afraid. The scary part has yet to come. Listen, you are a Greek demigod, who's been unclaimed for the last 16 years, quite an interesting case really, no monsters have ever come near you. I've come here to take you to a safe haven, called Camp Half-Blood."

Ally exhaled. "This is a lot to take in." She wrapped her blue sweatshirt farther around her body, as if warding off evil with a security blanket. "What do you mean, demigod?"

"It means you have one godly parent, from Greek "mythology" as they put it, but the gods are very real, Ally. Very real—and they sometimes have children with mortals—normal people. Although your dad seems very abnormal sometimes…but that's not the point."

"So, you just expect me to leave—drop everything, and disappear?" Ally was on the verge of a nervous breakdown—she even might start chewing her hair again.

"Yes," Annabeth patted the girl's arm, not knowing what to do at the moment. Her mind was on Percy, her demigod boyfriend, who was also the only demigod son of Poseidon. "You have to—for your own protection."
"But—Trish, and Dez—and Austin. They'll be devastated." Ally's voice trembled.

"Not if you don't tell them you're gone." Annabeth opened the practice room door. "Come on, Ally. We can't wait forever."
Ally felt like a different person as she walked to the door. Annabeth followed closely behind, holding her pencil up, like a weapon. "Why do you have a pencil, anyway?"
" Pencil? Well—" The music store's doors burst open, pushing the doors aside, and smashing the panes of glass inside them. Bits of clear sharpness flew toward Ally, and Annabeth, who pushed Ally behind her as she raised her pencil point at—mall shoppers?
"Annabeth, what's wrong with those people?" Ally put her hands to her face, rubbing her eyes, to see if she was in a dream. One lady, holding a new hairdryer, brandished it like a sword. "We are not shoppers. We are from the old times, long forgotten. We are—"

"Eidolons." Annabeth said. "I haven't forgotten you, not when we just defeated Gaea."

"You were the one who put The Earth Mother back into slumber?" The eidolons—or whatever Annabeth just called them—were now really ticked off. They narrowed their eyes, still filled with golden, and put their various hair care products to use. Hair curlers were flung at the demigods—one hit Ally sideways in the stomach—even flat irons, among other things. But then the worst happened—the eido-whatevers charged, but now Ally could see those weren't ordinary hair dryers and flat irons. It was like her vision had been missing something big here, but had suddenly shifted into greater detail. They were actually swords, made of shining bronze, and others, made of sparkling metal. "Whoa!" Ally yelled.

"What?" Annabeth shouted back to her. "What's wrong?"

"The-they're holding weapons. And their eyes are golden."

"You—you mean, you couldn't see through the Mist?" Annabeth narrowed her eyes. "This must be Hecate's work. Ever since we came back from our quest to stop Gaea, we've learned that the Mist is more complicated than it seems. My friend, Hazel, can even manipulate it."

Annabeth sprang at them, swinging her pencil—now a dagger, in its unMist-ified form. She dove low, hitting the ground just by a inch short of a hair-sword. "Ally, think! Use your instincts!" So Ally did the best thing she was good at: telling rule-breakers off. "Excuse me, ma'am, but there's no sword fighting in the store."
"We don't care about rules!"
"But what about Gaea? Wouldn't she be mad if she heard you not following orders?"

"What orders?"
"The ones that said 'Do Not Disturb'."
Annabeth crept toward the fire alarm, wearing her Cap of Invisibility. Tugging it down with all her might, the alarm went off like a giant police siren, shocking the eidolons from their bodily states. "Understand this, Allyson Dawson, and Annabeth Chase, a thought can be easily erased as it is brought to mind." And with that, the eidolons raced through the broken doors, into the dark night.
