Morning time came around for Royal Woods, the sun shining through the windows of the Loud House. It wasn't the light that woke up one particular Loud, however.

Weird sounds of groaning and moaning, and a mattress twisting around came from Lucy's coffin. Lynn tried to sleep through it, since her alarm clock hadn't started beeping yet. It soon got to the point where she couldn't, though, and so forced herself out of bed. She rubbed the dead skin away from her eyes and the drool from her mouth, and slowly walked towards her roommate's bed. Lynn rapped her knuckles on the wooden surface and said, "Wakey, wakey, Lucy."

Lucy immediately popped right out, scaring the living daylights out of Lynn and making her let out a girlish yelp. "And that's the benefit of having you as a roommate. An even better wake-up call than coffee." Something about her seemed off though… she seemed paler than usual. If that was even possible. "Also, I heard you making weird noises, you okay?"

Lucy simply tilted her head in confusion and groaned again. She lay limply on the side of the coffin and carpeted floor. "I feel like I'm burning up…" she said, before laying down inside again. It only took a moment for Lynn to realize what that meant. Lynn quickly made her way out of her bedroom, into the hallway, and closed the door.

"EVERYONE, LUCY'S SICK AND WILL BE QUARANTINED IN HER BEDROOM UNTIL FURTHER NOTICE! I REPEAT, LUCY IS SICK!" she shouted, scaring the living daylights out of the Louds that were sleeping before. They scattered out of their rooms and all throughout the house like cockroaches after a light had been turned on. After all, nobody wanted to be contaminated. The last time that happened… that was Hell On Earth. Even felt like it with the feverish symptoms from the flu virus.

After a few minutes, when all of the Louds were already downstairs, after going through a quick process of hygiene, they managed to organize themselves in order to avoid more chaos, and maybe gather some more information on their situation.

"Okay, who declared quarantine?" Lynn Sr asked.

"It was me, dad." Lynn told them. "Lucy was pale, and she was a bit weird."

Everyone looked at her like she was some sort of alien.

"Uh, Lynn," Lori said. "You literally just described Lucy. With or without sickness."

"No, I mean, she was even paler." Lynn explained. "She kept moving around in her bed, making noises, and apparently found it hard to sleep. She was groaning a lot when I talked to her, and apparently, she also has a fever. I don't know what it is, but it definitely is something." She crossed both her arms on her chest.

"Ah, Lucy's, like, not feeling okay?" Leni asked.

"That's what it seems." Lynn said.

"Yeah, dude, but can't she just be having a headache?" Luna asked.

"I'm not going to take any risks." Lynn said. "Better make sure most of us are healthy than risking checking her out."

"I think we should still check her out." Rita said. "We can't simply leave her in her room."

"But what if she is sick, and she escapes?" Lola asked. "I can't risk getting sick, I have a pageant in 3 days."

"There is no need to worry, fellow family units." A voice came from upstairs, and what appeared to be some sort of dwarf astronaut was there holding a briefcase. "This suit shall allow me to analyze our sibling/daughter's condition, avoiding any sort of possible contamination to others."

"Lisa?" Most of them asked.

"I'll be protected against any sort of danger. I'll only take a few instances." Lisa said. Everyone went upstairs, and then Lisa opened the door as little as possible and squeezed herself inside. She knocked on the coffin bed too. "Older sibling unit, it's me, Lisa. Lynn informed the family you might have contracted an illness of some sort, and I would like to run some tests just in case. Confirm to me, are you feeling any symptoms?"

Lucy popped out again, startling Lisa. Even if she found the suit quite unusual "Yeah, I've certainly had better days. I might have a fever or something, though I also feel nauseous."

"Those are certainly good indicators of some sort of sickness. Now," Lisa opened her briefcase, revealing all sorts of equipment. "It's time for your examination."

Lucy frowned, but didn't protest. At that point, she found the process to be no different from when Lisa liked and was allowed to use them test subjects for her experiments. And for the next 15 minutes, Lucy passed through a series of exams, from temperature and pressure measurement, to blood collecting and analysis. Every once in a while, Lisa took notes of the results collected.

"Okay, based on everything I've been able to determine on this short minutes, I've got good and bad news, one of each. The bad one is that I can't determine what you have."

"And what's the good one?" Lucy asked.

"I'll most likely be able to identify it on the autopsy."

Lucy just maintained her same emotionless expression.

"You're hard to scare, older sibling unit, that's a fact." Lisa said. "Childish behavior aside, I was not capable of finding a source of your symptoms. Everything seems to be working properly in your body. While there are some tests I didn't manage to do due to the short period of time I have before my presence to go to school is required, I'd recommend that you rest, at least for now, to avoid any sort of development of the sickness."

"Okay. And… you see that wolf mask near me?" Lucy asked.

Lisa looked around in confusion before noticing it. "Yes. It sure is a fine piece of art. Why do you ask?"

"It helps me relax. Could you hand it to me, please?"

Lisa raised an eyebrow at the odd request. "Err…I'm not exactly sure on how it would help you relax, but if you say so, I'm not the one to argue with someone's preferences." She did so and Lucy immediately put it on, even moving the bangs from her eyes to not cover the eyeholes. She turned to face Lisa again, gave a quick thank-you, and lay down again. Lisa was heading towards the door and was about to leave and explain the rest of the family Lucy's situation. She found a few things a bit strange, but maybe the strangest was the fact that Lucy's eyes were yellow. She couldn't remember any other moment she saw those, but they was sure looked to be the hue of yellow a human wouldn't show in regular conditions. In fact, they seemed oddly wolflike. For all she knew, though, it could've just been a result from the illness. Or maybe she just made a mistake, after all, she only had the chance to give them a quick glance.

She couldn't help but continue to think about it, though. What if it was something else? It could be something even worse than a sickness. Maybe something affected her liver, and she didn't catch it on the blood analysis, which was a bit unlikely. Still, she made sure that she'd make more examinations later that day., just to be safe.

Right now, though, she and the rest of her siblings had school and Lily had daycare. She explained that Lucy showed some symptoms, though her exams showed nothing wrong with her. So, they assumed that, for now, letting her rest was the best medicine. Well, Luan thought it was laughing, but even she knew that was something nearly impossible. When was the last time Lucy laughed? Had she ever done so at all? Was she even capable of doing so? Luan someday would still answer those questions.

After a series of different classes according to each and every siblings day schedule and grade, the Louds finally started to make their way home. Due to some of them having different dismissal times, some were able to get a ride home in Vanzilla while others had to walk home. Lucy was the only one of the elementary school kids who didn't have to face that path that day. While it may sound odd that the older kids (minus Lynn) were the ones that got a ride, it actually worked just fine for the Louds.

Lynn announced her presence by kicking to front door open, having jogged all the way from Royal Woods Middle School. Lisa and the twins were all on the couch watching an episode of Blarney The Dinosaur, seemingly content until Lisa tried to change the channel to a documentary after the first half of the episode ended and subsequently got attacked by Lola and Lana over the remote. Lynn chuckled and went into the kitchen for an afternoon snack for herself, which for her was a sub meant for two people.

Just then, she saw Lucy in there digging in the fridge and… wearing that wolf mask from yesterday?

"Luce, what you doing here?" Lynn asked keeping her distance. "Weren't you supposed to be resting?"

"I'm actually feeling a lot better. The spirits helped to heal me."

"Are you sure? No offense, but we don't want any sickness from you nor anyone. And what's with that mask?"

Lucy took out an entire pack of bacon and closed the refrigerator door, turning to face her older sister with those yellow eyes of hers again. "The mask is comforting." she simply said, and put all the slices of bacon from the pack into the microwave.

"And hey, save some bacon for us too! There's a lot left in there."

"Says the girl that eats meatball subs like they were candy." Lucy replied.

"That's because they practically are candy! But, point proven. Speaking of subs, move over a sec, I gotta go get one." Lucy obliged and Lynn pulled out a nearly-footlong sub that was bunched up together to save space. When she was about to give a bite of it, however, she noticed that Lucy was staring directly to towards her. "What?"

"Looks tasty." Lucy said.

Lynn raised an eyebrow. "You… like subs? Never saw you eat one."

"It's just look so good…" Lucy said, as she began approaching the snack, but Lynn quickly moved it away.

"Hey, you have your bacon already. Stay away from my food."

Lucy gave a low and barely-audible growl but was interrupted by the beeping sound from the microwave, signaling that her meal was ready. Quicker than Lynn ever saw Lucy move, she popped it open, took the plate out and dashed upstairs into her room. Even faster than the time Lola threatened her with glitter over the last slice of pie.

"What the-?" Lynn thought. She narrowed her eyes in suspicion and took a bite out of the 11-inch-sandwich. "Something just doesn't seem right…"

In the living room, Lisa noticed someone dashing upstairs in a rush, while the twins still fought for the remote. When Lynn appeared in her sights, she got even more confused, as she was the most likely to reach such amount of speed. She approached Lynn. "Older sibling, who was the one that managed to elevate their speed on such a high rate?"

Lynn slowly swallowed the piece she had bitten off and answered, "Lucy."

"Our fifth youngest sibling? She was supposed to remain in her bedroom. I shall see what's going on." Lisa said. She made her way upstairs and entered Lucy and Lynn's bedroom. "Sibling, I'm sorry to interrupt, however… why are you consuming such a high amount of salt-cured pork at the moment? I doubt that doing so while ill would be a good idea."

"Because I'm hungry." Lucy answered flatly, and went back to tearing into the strips of bacon.

"It's understandable that your stomach might require you to ingest alimentary products, however there are much healthier and better options to choose from."

"Let me guess, soup?"

"That's one suggestion. And probably one of the most effective to healing certain diseases." Lisa said. "Speaking of which, we shall proceed with the more detailed examinations, in order to conclude what illness you posses."

"Can I finish eating first, though? I haven't eaten all day. And what kind of examinations?"

"Unfortunately, I cannot allow you to continue to consume this product until we conclude what sickness is present on your body." Lisa explained, taking the plate out of her reach. "As for the examinations, I'll do everything in my reach, from X-ray, sample collection, internal inspections, and others."

Lucy let out another low growl, which was somewhat louder than before. She managed to stop herself from lunging at her little sister, though. Even though she had just taken her bacon away. Oh well, she could always get it back right after, right?

"Actually." Lucy said. "I'm feeling quite better now. I don't think we'll need those exams-"

"Nonsense. It's required for me to realize these tests so that I'm capable of providing an accurate update on your health."

"I said I'm fine, Lisa. Maybe it was just a passing thing, a hit-and-run cold."

"Even if your theory is correct, these sorts of symptoms do not heal with such speed. A cold usually lasts a minimum of 24 hours."

"Well, then this is the exception. I'm okay now, Lisa."

"Older sibling, I believe you don't comprehend how important these exams are to-"

"Lisa, I'm fine!" Lucy snapped, the aggressive tone catching the scientist off-guard. Never had any of the Louds heard her raise her voice, except for when she squealed in delight over learning that Ronnie Anne had a crush on Lincoln. And even than, there were doubts if she actually did so. "Now can I please have my bacon back?"

"S-sure…" Lisa said, a bit frightened. "But I have to inform you that this is not the wisest choice, when it comes to your health." Lucy gave her another glare, which was enough to get the nerd out of the room as quickly as possible.

"Primarily, the symptoms showed earlier today, followed by an aggressive behavior and change of emotional expression." Lisa said to herself. "There's certainly something unusual happening with her. And it's my obligation to find out what. However, I'll need some sort of physical protection and strength. Before that, though, I must prepare my equipment." Lisa said, as she headed towards her room.

Lucy watched her exit the room and her range of vision before going back to the meal that had been taken from her. That surge of anger was… strange. Usually when she was angry, it would come off as tranquil. Due to not being used to it, her vocal cords had tightened considerably due to her raising her voice. Instead of thinking it over even further, she chose to go back to eating the bacon in front of her.
