REVIEWS: Thank you all so much for the reviews, faves and follows. Thank you, too, for the support you're giving me. Love y'all! mwah

h9i6t3: Yes, of course. But, demigods would still feel something from the curses or spells inflicted on them. However, the Forbidden Spells (Imperius Curse, Cruciatus Curse and Killing Curse) will effectively affect them. The reason will be mentioned and explained in the story. Thanks for the review.

Finwitch1: Yeah, I know. The plot with Percy and Annabeth or the Seven going to Hogwarts is just too overused. So, that's why I'm making an original plot. And I agree, Lou Ellen IS the daughter of the goddess of crossroads and WITCHCRAFT, I just don't understand why they don't use her that much. By the way, thank you for reviewing.

Guest (Feather): Thank you and thanks to your review. As Dean Winchester would say, 'You're awesome.'

Guest (Passer-by 101): Cool penname. You're awesome, too, dude. And you will see what lies ahead in that door in the near future and why Hecate LOOKS sad. But, maybe she's not sad. She's just disappointed. I won't spoil anything. Thanks for the review.


CHAPTER THREE:
LOU ELLEN


FINDING SOME PRIVACY IN THIS gigantic castle was not that hard for Lou Ellen, as the very thought of her own professor quarters came into her mind. She scolded herself for forgetting the important matter, but after the meal in the Great Hall (and after a bunch of questions that were asked by the seventh years); she excused herself from her fellow co-workers and went to her quarters.

As expected, and like Michael had said, her things were already in her quarters. Her duffle bag was on the top of her comfortable-looking bed, and she dug out a drachma from a hidden pocket inside it.

"O Fleecy, do me a solid. Show me Chrissie Collins at Camp Half-Blood," she whispered, but not before preparing for the Iris message – entering the bathroom of her quarters, twisting the tap open, creating a mist and tossing the coin into the awaiting water on the sink.

The open air in front of Lou Ellen flickered, and a blurry image slowly formed before turning clear. However, the sight that greeted her made her groan. Di immortales. She was not staring at Chrissie but at the back of one Cecil Markowitz. Don't get her wrong, Cecil was one of her friends, but he tended to babble some useless things and other nonsense. It was only irritating Lou Ellen, and she remembered when she often smacked him on the arm when he blurted out things people didn't care about.

The sound she made didn't go unnoticed as Cecil, startled, whirled around to face her, Chrissie barely visible since Cecil was blocking the view of Lou Ellen and the chance to catch a peek of her half-sister. A grin broke its way onto Cecil's lips and he exclaimed, "Lou! Yes, Lou! Lou Ellen, my friend," with a slight tint dusting his cheeks.

"Hello, Cecil," Lou Ellen mumbled. "I hope I'm not interrupting but I have to talk to Chrissie."

Cecil nodded and assured her quickly that it was fine and he had no problem about it. He grinned again, this time, his pinkish cheeks turning a few shades deeper. The demigod son of Hermes rushed out of the Hecate Cabin and Chrissie finally appeared on her message, who offered her a kind smile.

"Cecil just went here to tell me about the obstacle course Harley was planning," Chrissie informed, her eyes glued to where Cecil had disappeared off to. Lou Ellen stayed silent, not wanting to hurt her half-sister's feelings by retorting snappishly that she didn't ask whatever Cecil said, but her eyebrows rose in confusion. "It was rather... interesting, to say at least."

"What obstacle course?" asked Lou Ellen.

"Nothing that's important right now," said Chrissie, though a grimace marred her face. The image swayed, but then cleared once again. The other daughter of the goddess of witchcraft was now looking at Lou Ellen. "How's your mission going, Lou?"

"It just started, Chrissie," Lou Ellen chuckled, used to her half-sister's question, nevertheless she answered her. "But I've got no classes yet, so I have the rest of the day to plan out my lessons. Can't afford to humiliate myself in front of the class, considering my age and knowledge towards witchcraft. I might be the youngest professor Hogwarts ever had, but I'm not sure. And besides, I've got an identity to cover. It's suspicious enough that I'm teaching at the age of seventeen-years-old, the same age as some of the seventh year students here."

"Ah, well. That's a good start, I guess," Chrissie said.

There was a moment of silence as both girls had nothing to say anymore.

Then, Lou Ellen tossed her sister a sly look. "You and Cecil were alone in that cabin before I IMed you. And we all know that two demigods with different godly parent can't be alone in the same cabin. What were you two doing?"

"Oh, gods. Lou, what the hell is wrong with you?" Chrissie said, hiding her face behind her hands. She looked a little green, Lou Ellen noticed. "I don't like the guy that way and there was nothing that happened between us. He was informing me about the obstacle course that Harley – you know, the Hephaestus kid – planned."

"Are you sure?"

Chrissie grumbled, and she spoke through a muffled voice, "I'm sure, you big tease. Besides, Cecil's smitten with someone and I'm not going to tell you."

"Yeah, yeah," Lou Ellen rolled her eyes. "Listen, Chrissie, I—"

The image of Chrissie flickered then shimmered. Before Lou Ellen could utter another word, the Iris message vanished. Please deposit one drachma for another five minutes, a woman's voice said.

She frowned, checking her pockets if she brought an extra drachma but found none. Lou Ellen clicked her tongue as the connection snapped, breaking her conversation with Chrissie

Well, she could contact Chrissie next time.


It seemed that even at the magical school that had boundaries that could keep monsters away, Lou Ellen landed herself into another trouble.

It wasn't her fault, really. She was just walking around the school, giving herself a tour since there was no one to help her, all of the professors had their own classes, so they were busy. While she walked, she started a conversation with the people inside the paintings. One of those people was Violet, and Lou Ellen quickly bonded with her. Violet was a nice person, or painting.

During her tour, she stumbled upon the memorial of the Second Wizarding War she learned from her mother. She also talked to paintings of the ones who died during the said war.

And after that, well, that was how her problem started.

Lou Ellen decided that she was tired circling the castle, and it was time to plan her lessons for tomorrow, when she crossed paths with a cat. Normally, she would've cooed and pet the animal until it purred. But the cat didn't even give her a chance to do that, as it hissed at her and would've probably claw at her face if she didn't back off. "Bad kitty," Lou Ellen said as she glared at the cat.

"You don't just claw on someone's face, that's basically rude," she grumbled as she stood up. The cat hissed again and when Lou Ellen turned her back against it, the cat jumped onto her head, clawing at her hair. "What the – Get off! Get off, you stupid cat! I swear, if you're a monster in disguise I'd –" she yelped as the cat scratched her scalp. "That freaking hurts! That's it, cat, I've had enough of you."

She whipped out her wand that was on her pocket and pointed it blindly at the cat, "απολιθώ (apolithó)!", but nothing happened. Lou Ellen stared at her wand, ignoring the growing pain on her head. Realization dawned on her and she pointed it again at the cat, "Petrificus Totalus."

The cat went stiff as a board, falling to the ground. Lou Ellen smiled in triumph, and winced when her scalp throbbed. She gingerly touched the wound and her hand came back with smears of blood. She sucked in a breath as the pain intensified. She tensed when she heard the heavy footsteps approaching her direction.

She was preparing to face the monster, when an old man (definitely human) spun around the corner. He saw Lou Ellen and the cat, lying petrified near her. His eyes grew in horror and he screamed while pointing his index finger at her, "You! I knew I shouldn't have trusted you! You freak killed Mrs. Norris."

She scoffed, "I didn't kill the cat. If you're just smart enough to actually check on your 'Mrs. Norris', then you would know she's just frozen."

The old man glared daggers at her and scrambled towards his cat, checking if it was really died. When he was finished, he cried out, "Dark magic! You used dark magic. I ought to tell the Headmistress about it. Oh, you wait. You'll be banished here before you can even start your plans!"

"What are you blabbering about?" Lou Ellen directed a strange look towards the old man. She couldn't understand what he was muttering about. "I didn't use any dark magic; a full body-bind curse is different from petrification. Besides, your cat first attacked me and I only defended myself."

"Rubbish," the old man spat. "Tell that to the Headmistress."

Lou Ellen fumed on the way to the Headmistress' office, muttering darkly under her breath and calling Filch (the older man's name, she later learned) some insulting profanities. She didn't really want to go but Filch was persistent and practically forced her to come with him.

Because she was busy cursing the man, she didn't notice that he had halted on his pace until she bumped into him. Apparently, they had stopped in front of a gargoyle. "What're we—?"

Filch shushed her. The gargoyle spoke, "Password?", and Lou Ellen barely blinked. Of course, if statues could be brought to life and could talk, surely gargoyles could, too. She had a feeling that maybe she did see a gargoyle or two during the Battle of Manhattan when she was fighting alongside Katie Gardner and the other thirty-and-above demigods.

Filch replied, "Albus Dumbledore."

The gargoyle was silent for a moment, and when Lou Ellen heard a rumble, the gargoyle was turning in a round motion as it shifted higher, spiral stairs forming below it. Filch beckoned her forward and they head to the Headmistress' office. Filch stopped, with Lou Ellen following, as he came face to face with the wooden doors that separated the office from the stairway. He knocked three times on the door, and a stern voice called out from the other room.

"Come in."

"Headmistress," Filch started as he entered the room, throwing another nasty glare at Lou Ellen's direction. "This person you call a staff member petrified Mrs. Norris," he shoved his cat in the line of Headmistress McGonagall's eyesight. "She performed dark magic! Dark magic, I tell 'ya. You hafta fire her!"

"Whoa!" Lou Ellen exclaimed, offended. "First of all, like I told you, it's a full body-bind curse not petrification. Secondly, your cat attacked me first. You can't just fire me because I acted on self-defense."

Headmistress McGonagall raised her eyebrows at the two of them, her facial expression screaming at them that she was not, even a little bit, amused. "Mr. Filch, you want me to fire the new Defense Against the Dark Arts professor because of a misunderstanding?"

"It's not a misunderstanding. She killed my cat!"

"Petrified," Lou Ellen insisted, getting fed up with the argument with him.

The headmistress narrowed her eyes at them, her lips formed in a thin line. "Return to my office if there is a real problem. And no, I will not fire Lou Ellen here, Mr. Filch. Now, get along."

Lou Ellen sent a smug look towards the old man, who grumbled as he exited the office. Then, she turned to the headmistress, wearing an apologetic look. "I'm really sorry, Headmistress McGonagall, it's my first day here and I'm already on the bad side of one of your staff."

"Nonsense, Professor," said McGonagall, the corner of her mouth twitching. "Everybody gets on the bad side of Mr. Filch."

Lou Ellen chuckled, "Figures. Anyways, I'll be going, Headmistress."

"Do enjoy your stay in Hogwarts."

"Thanks."


Night came and Lou Ellen was once again alone. She tried to spend the night chatting with Chrissie, but she decided against it. She didn't bring that many drachmas with her, and she swore that she'd only IM if it was an emergency. Dinner was already done and the students were all asleep (except for the students—what was it? Prefects?—who were patrolling the school) and possibly the other staff.

That was, until someone knocked on the door.

Lou Ellen stopped skimming on her spell book and stared at the door. Who would've visited her in this time of night? Surely not a student, she hadn't even started a class yet.

Climbing off her bed, she walked towards the door and opened it.

"Galaxy-themed pajamas, seriously?"

"Michael? What are you doing here?" Lou Ellen asked, surprised to see him. Looking down, she smirked. "And are those cat-themed boxers? You must know that your robe doesn't really cover it nicely."

"What?" Michael looked down, too. Red in the face, he quickly covered his undergarments with the robe.

Lou Ellen chuckled, "Gods, you are such a dork."

"Whatever," he muttered, gaze locked on his slippers as if he found it interesting.

Lou Ellen cocked her head slightly, her curiosity spiked. What was he really doing here? Shouldn't he be asleep on his own quarters? "Michael, do you need anything? Is that why you're here?"

He muttered something she didn't really understand. "What?"

"I said I want to wish you luck for tomorrow," Michael said.

Lou Ellen smiled, "Aw, that's so sweet, 'ya dummy. You couldn't wait to say that to me tomorrow, huh?"

"It didn't cross my mind," he replied, grinning sheepishly.

"You're not so bad after all," Lou Ellen kissed his cheek. He blushed, turning crimson, and stuttered. "Good night, dude."

"G'night, mate."


It's finally finished. Oh, gods. So much hard work, especially since I've got no idea what to do next, other than slipping into another point of view. How long was my last update? Two, three months? Anyways, here it is. As you can see, this is only a filler chapter. Which I'm a little great at. Who am I kidding? I'm the worst.

There's a little spoilers here. Yep, you're correct. It's the obstacle course courtesy of one Hephaestus kid, Harley. I'm hoping you guys like the appearance of Cecil, but do not worry, my friends, this is not Cecil's last appearance in this story. Maybe he'll appear again in the mid-chapter or he could be in the last few chapters of this story.

I've got a question: which ship is better? Loucil (Cecil and Lou Ellen) or Milou (Michael and Lou Ellen) or Cessie (Cecil and Chrissie)? State your votes in the comment section.

As for why Lou Ellen's spell didn't work in Greek, it will be explained in the future. Until next time, bye!
