Lucy Weasley's Sisterly Lecture

or

Wisdom from the Head Girl

Molly Weasley woke up unsure of where she was. She fought through the grogginess and the forming headache and forced her eyes open. The Holyhead Harpies poster (signed by the entire team) on the ceiling above her was her tip off. She was in dormitory. In her own bed. Phew.

Molly often left her room on Friday night unsure if she would be coming back before the next morning. And she'd had it happen quite enough times where she woke up somewhere in the castle that was not her own bed, that she didn't even really think about it any more. She would wake up, do a quick evaluation of herself and her surroundings, realize (or take an educated guess at) where she was, and then ask herself if she remembered how she got there. Usually she did. Sometimes she didn't.

She racked her brain to see if she could remember what had happened the night before. It was difficult because her whole body hurt and her thoughts were still a little fuzzy and her head was throbbing.

The Annual Back to School Bash thrown by the Gryffindor seventh years the first Friday night they were back at the castle was usually one of the craziest parties of the year. Each year, the students tried to outdo last year's seventh years, and this year, Molly was pretty sure, had been one of the best. She'd been attending since she was a second year (though it was meant to be strictly fourth years and up), so she felt like she could give it an accurate rating.

The night started coming back, slowly, piece by piece. Her outfit had been on point- just the perfect amount of sluttiness- and she'd gone to the party with... Aaron Carter? No, it was Keira. But she hadn't stayed with Keira for long because Keira had started flirting with Ben Saunders. And then Molly had started flirting with Aaron. That's why she was confused- she'd arrived with Keira but hung out with Aaron. Merlin, he was fit. Had they hooked up? She searched her fuzzy memories...

They had! No shagging, but they definitely made out. And then... what had happened after that?

"Eh-hem," coughed a naggy, nasally voice that she knew all too well. And suddenly it all came rushing back to her. Lucy.

She sat up in her bed, rubbing her eyes and ignoring how much it hurt to move, to glare at her older sister, who was sitting on her trunk at the foot of the bed. Lucy glared back.

"Welcome back to the world," Lucy said sarcastically, getting up from the trunk and sitting on Molly's bed with her. She quickly scanned the rest of the dorm. They were alone.

"God, Lucy, go away! What, did you sit up all night and wait just so you could lecture me?" Lucy smiled her classically infuriating "I-know-more-than-you-and-I'm-looking-down-on-you-because-you'll-never-be-as-good-as-me" smile.

"Please, Mol. After I got you safely in bed," her voice was condescending as ever, "I went up to my dormitory and got a full night's rest. When I woke up, I checked on you, but you were still completely out of it- sleeping like a rock- so I went down to breakfast. And then I came back, and you were still sleeping. And so I waited. Muffin?" She held up a mouthwatering blueberry muffin that under normal circumstances Molly would have devoured in a second. Such as it was, she felt queasy at the sight of it.

"No thanks," she said, but Lucy shoved it into her hands anyway.

"It'll help you to have some food in your stomach." And she was right. Why did she always have to be right? She took a small, resentful bite of the muffin and tried not to vomit. Or enjoy it.

"Ok. Thanks for the muffin. Now leave." She knew it wouldn't be that easy.

"Oh no. You're not getting rid of me that easy." Told you so. "We need to talk about what happened."

What had happened was this:

Lucy was monitoring the party, as was her job, and had just discovered that the punch she had been drinking was spiked with alcohol (she didn't even know about the extra cases of firewhiskey that were being held off the premises). Now, seeing as the majority of the party-goers were not of legal drinking age, this, of course, was against the rules.

So Lucy turned to the Head Boy (who was also one of her best friends), Corey Montague, and asked him what they should do. Corey was 5'9 (Lucy's same height), skinny, and wore thick, vaguely circular eyeglasses. He had a head that was a bit too large for his body, curly gingery-brown hair, and a sad, scraggly little beard that was more copper-colored than the hair on his head was. He was too smart for his own good, and spent most of his time coming up with intellectual jokes that would go over most people's heads. Lucy, however, found his jokes hilarious, and seeing as she was one of the few who did, they had bonded over this. She was secretly in love with him.

Corey was having a mild amount of fun at the party, enjoying a little sense of teenage normalcy for as long as it would last. But he was also a stickler when it came to the rules, and he knew he couldn't let them go so easily disregarded right in front of him.

"Who brought the punch?" he asked her, but Lucy didn't know.

"Do you think it was spiked when they brought it, or someone added to it afterwards?"

"I wonder if there's more around?" They always spoke like this, in questions, when they were "on duty." Together they searched the party, scanning the crowd and sniffing people's drinks and not caring who's good time they were ruining in the process.

"Do you think there's some up in the dormitories?" Corey asked, and Lucy stopped in her tracks, pulling him to face her.

"The dormitories?"

"Well don't you think-?"

"Corey! You didn't assign anyone to patrol the boy's dormitories?"

"Was I supposed to do that?"

"Why did you think I was giving Penny Higgenbaum all those instructions earlier?"

"Well…" But Lucy was already storming away. She headed straight for the boy's dorms, and used the spell to get past the no-girls restriction (which she thought only she knew because of Head Girl privileges, but was actually a very widely-known and commonly used spell). She marched up the stairs, Corey close at her heals, listening on each landing for noise and/or inappropriate behavior.

The first, second, third, and fourth years were all being good. On the fifth year landing, she found some giggling girls, who she promptly sent back down to the party after giving them, and the boys they were with, a detention each. On the sixth year landing, it was worse. There was a crowd of students, boys and girls, gathered around a closed doorway. A few had their ears pressed to the doorway, including James Potter, who was giving a play-by-play commentary for the rest.

"Now they're… Oh my god, I hear bedsprings! And moaning!" Laughter all around.

"What in Dumbledore's name?! Stop! Stop it, all of you! Detention for everyone, get away from there!" Lucy shoved them all out of the way, hoping that Corey was taking note of who all these people were, and upon getting closer to the door, did indeed hear bedsprings and moaning. She didn't even want to know who was in there. "Corey, since this is your fault, you can you handle this. I'll go check on the seventh years."

The seventh year landing was relatively quiet. Most of the seventh year boys were down in the common room, enjoying their party. There was, however, one door that was left slightly ajar. She could hear conversations as she got closer, but nothing that sounded ridiculously inappropriate. Nothing like downstairs.

She was definitely unprepared for what awaited her.

As she swung open the door, she saw a few seventh year boys and some girls all sitting somewhere or another in the room. Maybe 10, total. She recognized her sister Molly's best friend Keira Connolly hanging on to Ben Saunders like she needed him to breathe. That was we she realized that she hadn't seen Molly all night, and wondered where she could be.

That was when she saw an all-too-familiar head of Weasley-red hair in the back of the room, on one of the beds. She was wearing next-to-nothing, her shirt discarded on the floor with her black lacey bra on display for the whole world to see. And she was tangled in a mass of limbs with some boy who was practically eating her face off. Lucy's baby sister was being violated on some seventh-year's bed!

"Molly!" Lucy screamed, startling everyone in the room who hadn't noticed her before. The Head Girl, who everyone knew, was scary just in general- scary on a good day. Now, as she stood there, fuming with anger… she was terrifying.

Molly had been a little too out of it to even hear her sister's scream, and continued wrestling with the guy in the back of the room. It was only when Lucy bounded across the room, yanked them apart, and slapped Aaron Carter across the face, that Molly noticed her sister's arrival.

"Luce?" she had asked, confused by what was happening. Lucy grabbed her by the arm, yanked her off the bed, picked her shirt up off the floor, and dragged her out of the room. Molly didn't even protest, she was too busy trying to fight the queasiness she suddenly felt overcome her when she was forced to stand up. Lucy set her down on the floor in the hallway so she could turn back to the kids in the room and let them know exactly how much trouble they were in. Detention for a month- no, 3 months!- not to mention the point deduction they were going to get! Just wait until Headmistress McGonagall heard about this!

Meanwhile, out in the hallway, Molly had vomited all over the floor. When Lucy came back out Molly attempted to argue with her, asserting that she hadn't done anything wrong, and Lucy was overreacting, yadda yadda yadda, so Lucy, who couldn't deal with that at the moment, put her to sleep with a quick sleeping charm. She wondered if she would be able to move her. She used Wingardium Leviosa to levitate her a few inches off the ground, and was able to get her back down the stairs to the sixth year landing where Corey was interrogating James about what had happened there.

"So then they said they were going to- oh, bloody hell, Lucy, what happened?!" James exclaimed upon seeing them. Lucy was bright red with anger and the effort of magic-lifting a load as heavy as a person, and Molly had vomit in her hair. Not a pretty sight.

"I can't-" she attempted to speak as she set her sister down again, gasping for breath. She decided an explanation wasn't worth it. "Can someone help me get her back to her room?"

By "someone," she had, of course, meant Corey, seeing as he was the other person here, besides herself, who was at all responsible. But Corey couldn't lift Molly any better than she could. Maybe if they both…?

While Lucy contemplated this, James walked right over and scooped the sleeping Molly up in his arms with little effort. Lucy was still furious with him for his stunt on the train earlier that week (and the stress zit that incident had given her), but then again, when was she not furious with James? And he was Molly's family, too. He stood there, frowning down at her.

"Where's her shirt?" he asked, and Lucy, embarrassed that she'd forgotten, realized that she still had it in her hands. Together they lifted her limp arms and helped get it back over her head. Then Lucy sighed, rubbing her head, which was suddenly pounding. "Where to, chief?" James asked, waiting for her to lead the way.

Together, the two of them- with Corey lagging somewhat behind, unsure of what to do with himself- took Molly all the way back down the stairs. At the base of the stairway to the girl's dormitories, Lucy had to assure the new 5th year prefect Penny Higgenbaum that it was fine that these two boys come up- they had some business that needed attending to.

James was struggling a bit once they got up the first few flights of stairs, and was all too relieved to set the sleeping girl down in her own bed. He and Molly were somewhat close- they played on the Quidditch team together, after all- and he was sorry to see her like this. He kissed her lightly on the forehead, nodded to the Head Boy and Girl, and left swiftly after that. Lucy assumed he would want pardon from his offenses for his good deed, and she would probably end up giving it to him. He'd gotten away with far worse, so she didn't really see the point.

Lucy tucked her sister in, and after giving explicit instructions to Corey to please assign someone reliable to monitor the boy's dormitories, she decided to go to bed. She couldn't really handle much else, and she trusted Corey to do his job. And without trust, what did she have?

So that's how they had gotten here, where we left off.

"We need to talk about what happened."

"No we don't!"

"Yes, we do, Molly! Merlin, you're 15 years old! You were drunk out of your mind, practically shagging some seventh year-"

"Not just some seventh year, Luce! Aaron Carter!"

"You think I care who the chap was?! That's not the point!"

"Well what is the point? It's not like I've never shagged anyone before!" At this, Lucy looked rather shocked. She was a bit more ignorant about Molly's past than she would like to have thought she was.

"What?"

"Oh, come on, Lucy! Don't be stupid. Everybody's shagged someone!" Lucy hadn't, and Molly probably knew this, but at the moment she was just trying to make a point, not be any kind of accurate.

"Who?"

"What?"

"Who have you shagged, Molly?"

"Merlin! I'm not telling you that! Make an educated guess!" But Lucy wasn't enough a part of her sister's life to even begin to guess who it could have been. Had Molly ever even had a boyfriend?

"How many?"

"No! I'm not telling you that, either! Mind your own bloody business!"

"1? 2? 3? More than 3? Please tell me not more than 3."

"I'm not telling you anything!" The real answer was 4. "Now, are you here for a reason, or just to annoy the hell out of me?"

"I'm here because I think you need help."

"So this is like an intervention?" She was being sarcastic. Lucy was not.

"Yes. That's exactly what this is. An intervention."

"This is stupid. Last night wasn't anything special." And it wasn't. While it had been a good party, Molly had attended good parties before.

"What are you saying?"

"I'm saying where where you with all this last year?"

"Last year? You're saying that you've gone to parties like this before?" Molly didn't answer, just looked at her with an expression that read: Um, duh? "When you were fourteen?!"

"Bloody, hell, Luce, stop screaming! You're so shrill sometimes."

"Shrill?!" Lucy shrieked, rather shrilly indeed. And then, realizing what she'd done, she took a few deep breaths to calm herself before continuing. "Where do you even find parties to go to?"

As far as Lucy knew, there were only four or five parties a year. The back-to-school one, a few random Quidditch celebrations, the Christmas party, and the end-of-the-year festivities. All of these were monitored, and usually didn't get as out of hand as last night had.

Molly, however, knew the truth. She knew that there was a party (sometimes multiple) every single weekend, if you knew where to look and who to talk to. They were usually held in unused classrooms (after hours, of course) and protected by sound-muffling charms and such over the doors. Lucy, of course, as the Head Girl, would know nothing of these against-the-rules, strictly under-the-table operations.

"Like I would tell you!" Molly exclaimed. She sometimes wondered if Lucy fully understood the disadvantage that being Head Girl put her at. She could never have any fun, she could only ruin other people's. But then, Molly thought, ruining people's fun obviously gave Lucy some sort of thrill. It always had.

"Fine, don't tell me! But you can't go to any more of these parties."

"What do you mean, I can't? I can and I will. You're not the boss of me." Both sisters were furious.

"I may not be, but I happen to have a direct line of contact to the people who are." She did not just threaten to tell their parents on her.

"You did not just threaten to tell Mum and Dad on me! Why don't you just but out of my life? You're not my Mum, and you're not my friend, so why should I even listen to you?"

"Because I'm your older sister! Because I care about you."

"You don't care about me! You care about being in control."

"This isn't about me, Mol." Lucy had been accused by her sister of being a control freak one too many times to let it phase her anymore. It was Molly's favorite argument to use against her.

"Of course it's about you! It's always about you! You have to be perfect, and you have to run everybody's lives, and you have to be in control."

"That's not-"

"But you don't own me, Luce. I'm going to do what I want, and you can't stop me." She was being defiant, and she was quite enjoying how much it seemed to annoy her sister.

"You're only fifteen, Molly. You can't just do whatever you want, whenever you want."

"Yes I can," she insisted, crossing her arms and pouting.

"You're acting like a child. You're exactly proving my point." What Molly really wanted just then was to just be left alone. She was prepared to agree to whatever stupid thing her sister made her promise (no promises she intended to keep, of course), if Lucy would just go away.

"So what are you going to do about it? Are you just going to tell mum and dad on me?"

"No. I'm going to give you a chance."

"Ooh, a chance?" Sarcastic again. "Do tell."

"You're a smart girl, Molly. I believe that. You just… haven't grown up yet. You're completely irresponsible." Molly rolled her eyes. She'd heard the "irresponsible" thing just as many times as Lucy had heard the "control freak" thing. "And you're a fifth year now. Which means you have OWLs this year. Which you really need to pass if you want to have any kind of respectable job one day."

Lucy had gotten (almost) straight O's on her OWLs. O's in everything but Potions, which she'd gotten an E on due to one stupid mistake in the temperature of the flame messing up her entire potion and hence the whole practical portion of the exam. She didn't like to talk about it.

"Maybe I don't want a 'respectable job.' I want to play Quidditch, and you don't need OWLs for that." Now it was Lucy's turn to roll her eyes. She thought Quidditch was a complete waste of time and energy, not that she'd ever say as much to her Quidditch-loving family.

"Well that doesn't mean you should rule out all your other options by getting a bunch of T's on your exams."

"I'm smarter than a troll! I wouldn't get a T."

"I don't know if you would or not. All I'm saying is that you're not going to pass if you don't put any effort in."

"All you're saying is that I need to be more like you."

"Well, it wouldn't hurt! I am top of my class. And I, for one, have never-"

"Shut up! Bloody hell, just shut up!" Molly had heard enough. "You're so judgemental! All you do is look down on me and judge me and try to make decisions for me! I didn't ask you for your help."

"But I'm still going to give it to you. I keep people out of trouble, Mol. It's what I do. So, from now on..." Molly waited anxiously to hear what terrible punishment her sister would inflict, and Lucy paused for dramatic effect. "You and I are going to hang out more."

"What?" Molly asked, not fully grasping the brilliance of Lucy's plan here. The plan, basically, was to keep an eye on her sister whenever she could, and keep her by her side on weekends and such, when Molly would usually be out partying. Watch her and guard her under the pretense of "hanging out."

"You heard me. We're gonna hang out! We can do all kinds of stuff together! Go to the library…" Molly shuddered at the thought, but the Head Girl was just getting started.

"Is that really necessary?" Molly asked, feeling queasy all over again. Lucy put on her falsely sweet voice because she knew it would annoy her sister all the more.

"Oh, don't think of it like that. It'll be fun! We'll be like those sisters who actually like each other and have posters that say stuff like 'God made us sisters, but our hearts made us friends.'"

"That's not a thing."

"Sure it is! Oh, this is gonna be so great! We'll have so much fun! Maybe I'll even take you on a patrol with me!" One of Lucy's duties was to patrol the halls after hours.

"Or not. You know, we'll see." Molly didn't really think her sister was being serious. She had no idea how far Lucy was willing to take this.

"Sure. We'll see," Lucy said, getting up from the bed and heading towards the door. "Hey, what are you doing later?"

"Gee, Luce, I don't know yet." Most likely avoiding you.

"Well that's ok! I'll find you!" she exclaimed, opening the door and stepping halfway out.

"Like hell you will," Molly muttered.

"What was that?" Lucy asked, stepping back inside.

"Nothing!"

"Alrighty, then. See you later!" Lucy winked as she headed out the door. The younger girl groaned and flopped back on her pillow, knowing that Lucy never let things go, and was a very, very persistent person. She would never give up.

Out in the hallway, meanwhile, Lucy smiled triumphantly to herself before strutting off to the Head's office to file some detention slips and (hopefully) find Corey to tell him all about her genius new plan. She really did get a kick out of ruining other people's good time

Hope you enjoyed that chapter! Please, please review if you did. These two have a lot to learn from each other, however resistant they may be. Lucy needs to be less uptight, and Molly needs to start taking things seriously. Also, they need to learn to hate each other less. The next chapter I think is gonna be about Roxanne, who's only made a brief appearance so far. Read on! -Maddie
