AN: I'm back! This chapter took me a bit longer to start just because I like to have all of my facts straight before writing it. Pretty much everything I put in this story Hogwarts related should be consistent with the actual books. Anyways, I hope you enjoy! I lovvveee reviews; they keep me going :)

"So what's your first class?" Alison asked Sarah, who was sitting adjacent to her at the end of the table.

"Defense against the Dark Arts, with that creepy Moody bloke."

"Who's that? The one that walked in late yesterday? With the cane?"

"That's the one. The one who fucked up the ceiling."

Alison smacked Sarah's arm, causing her to drop her toast, "Oi!"

"Watch your language. Seriously, it gives me a bad name, the two of you talking like hooligans."

"The way I speak ain't got nothin' to do with you. I think it's pretty clear that we had different upbringings, yeah?" Sarah said smartly. Alison rolled her eyes.

"What do you have first, then?"

Alison looked at her schedule, "Apparently Divination, what kind of fluke class is that?"

"'Dunno, maybe you'll become a seer."

"Ugh, don't say that, I don't want to pursue any magical career. After this, I'm going to college and getting a degree in kinesiology."

"Well that's just like… massage therapy, innit?"

"No, Sarah, kinesiology is different. It heals."

Sarah waved her hand, "Either way, how are you going to go to college with no high school experience?"

Alison shrugged, "I'll have to get a GED certificate."

"A GED?"

Alison nodded, "Gen-"

"General educational development. People have to take classes and pass tests to certify that they have high-school level academic skills." Cosima said approaching the pair.

"Oh, look who decided to show up," Sarah said sarcastically, "Oi, Cos, did you get that stick out of your arse last night, or should I prepare myself for another verbal lashing?"

"Sarah!" Alison chastised.

Cosima looked down guiltily, wringing her hands. She was visibly uncomfortable, not going unnoticed by Alison, who reached out and squeezed her hand. She knew from being by her side for two years that the girl was sensitive.

"What made you so upset yesterday?" Alison asked.

Cosima shrugged, "I don't know, I guess it just felt like you were ganging up on me," she mumbled.

Sarah barely heard her over the bumbling chorus of people that were also eating in the great hall, "I was just asking you a bloody question, Cos."

"I know! I know and I'm really sorry for flipping shit, I was just irritated that whole night, and I took it out on you guys," Cosima looked up at Sarah with the best puppy eyes she could manage, "Forgive me?" she said, jutting her lip out.

Sarah caved nearly instantly, "Come here, you silly tit," she said holding her arms.

Cosima beamed and shuffled across the table into her arms.

"Talk to me like that again, and I'll break your glasses in half," Sarah said with a laugh.

"That's a pretty idle threat, Sar. There's a spell that can fix them, and it's pretty easy."

Sarah looked at her, "Oh yeah?"

"Yeah, it's- hey!" she shouted when Sarah snatched her glasses and bent them until they snapped. "Hey, easy, those cost like 10 galleons!"

Sarah looked at her, "Really?"

"Okay, more like 5, but still, they're sensitive!"

"Jeez, Sarah, you can't just go around breaking people's glasses!" Alison scolded.

"She said she knew a spell, so I wanted to see it. It's school, yeah? Teach me, Professor Niehaus," Sarah said tossing Cosima the pieces of her glasses.

"It's okay, I've got you." Cosima said to her glasses, making her sisters shake their heads. She placed them gently on the table pulled out her mahogany wand and chanted, "Oculus Reparo."

The other two watched in awe as the glasses fixed themselves right on the table. Cosima inspected them and put them back on her face with a cocky grin. Alison clapped as Sarah just stared at Cosima's face.

"Do it again," she said as she reached for Cosima's glasses again. Cosima smacked her hand away.

"Hell nah, dude. One time show."

"I guess that's what being in advanced spells classes will get you," Alison said.

"You're in advanced spells classes?"

"Yeah, man, why do you think I was never in your classes? And it's not really advanced, I'm just taking fourth year classes."

"I just thought it was at a different time. Shit, Cos. That's badass."

Cosima raised her chin, "If I'm gonna be a super spells inventor, I need to get ahead, right?"

"Hmm. I guess," Alison said gathering her materials, "I have to get ready for class. You two, good luck with whatever you have today."

"Toodles, Alison," Sarah teased. Cosima punched her in the arm.

"Shut up, don't use my word."

Sarah laughed, "What class do you have first?"

"Umm… Transfiguration 4 with McGonagall."

"Pssh," Sarah said, unattractively, "Have fun with that old bat."

"She's not that bad Sarah, she just likes to follow the rules. And you definitely do not," Cosima said chuckling.

"What, as opposed to you?"

Cosima straightened her tie with a smirk, "Exactly."

"Yeah right, don't pretend I don't see you and your friends," Sarah accused.

Cosima put her hands on her hips, "Doing what, exactly?" she said nervously.

Sarah pressed her index finger and thumb together and put them to her lips a few times. Cosima gasped, pushing Sarah's hands down and looked around, hoping no one noticed them talking. Sarah laughed, "The astronomy tower? Really, Cosima?"

Cosima looked down, "We didn't think anyone would notice."

"I didn't until one particular dinner when you couldn't stop laughing. I'm surprised the prefects haven't smelled it already. Who's giving it to you anyway?"

"…Justin Finch-Fletchley."

"That random bloke that's everywhere and nowhere?"

"That's the one. His parents were muggles, and one of his grandparents or whatever has some sort of illness that gets them marijuana… so…" Cosima shrugged.

"Aren't you a little young for it?" Sarah asked knowingly.

"I'm older than I look, Sarah." Cosima said, looking over her glasses, "Trust me when I say, I know the risks."

"I just don't want you getting into trouble, yeah?"

"Oh no, Sarah, I'm careful as hell," Cosima said, patting her on the shoulder. She leaned in closer to Sarah and whispered, "McGonagall still likes me."

Sarah shoved her away, "Oh piss off!"

Cosima giggled and walked away, "Try harder!"

"Fuck you!" Sarah called after her.

Cosima walked into the Transfiguration chamber minutes before class was to start. She mentally pat herself on the back for being on time, and couldn't stop a smirk from creeping onto her face.

She was looking for a seat before she spotted a familiar face and suddenly felt as if someone had used a glacius spell to her spine. The girl from the ceremony was sitting in her class, and she was sitting… alone?!

Cosima heard another Gryffindor boy behind her, probably heading for her seat before she all but ran to the vacant seat, bumping into the table as she skidded to a halt.

The girl looked up at her, half in question and half in amusement.

Cosima laughed nervously, "Sorry… the floor, you know," she tried to explain as she moved her hands around.

"Hmm," the girl said in… understanding?

"Umm… you're from Beauxbatons?" she asked politely, doing all she could to stop herself from face-palming. Clearly the girl was from Beauxbatons.

"Um, yes." The girl responded with a small smile, and that was all it took to make Cosima melt.

"Oh. Well, I'm from Hogwarts," Cosima said casually before recovering, "Wait, no- that was obvious wasn't it? Shit, uhh…" she tried before deciding it was probably best to stay quiet.

Apparently Cosima's discomfort was amusing to the blonde girl, because her giggles caused Cosima to look back up at her with cheeks redder than Gryffindor's banners.

"Je suis désolée, you are… very funny."

"I- I am?" Cosima said, her grin spreading, "Sweet."

The blonde was going to say something else, but McGonagall walked in, quieting down the class. She introduced herself to the visiting students, before introducing the first spell, Duro.

After the explanation and demonstration, McGonagall distributed various pieces of cloth out to the class, and instructed everyone to turn them into stone.

Cosima had trouble at first, but then looked over the book and saw the picture give a slight flick of the wrist at the top of the wand motion, before curving it back down. Once she included this, she successfully turned her piece of… what looked like an old robe, into a small stone. She did it two more times before she heard someone speak next to her.

"You did it."

She looked up next to her to see the girl standing closer than usually accepted by society, pointing at the stones she produced, "You… le chiffon… umm"

She took a couple of small steps backward before chuckling nervously, "Yeah, I uhh…" she scratched at the base of her head, trying to explain it in the simplest way possible, "There's a small flick of the wrist, after you bring the wand up," she tried, gesturing it with her hand.

The girl watched carefully, "Um… show me?"

Cosima nodded and took out her wand again, pointing to one of the girl's pieces of cloth, "Duro," she chanted, making sure to accentuate the flick of the wrist. As the cloth coiled tightly into stone, the girl's eyes widened. She took out her own wand and tried it again, but her cloth only coiled into a soft ball.

"No, you're-" Cosima began to explain as she uncoiled all of the previously transfigured cloths, "You're not flicking hard enough, you have to give more. flick." she said as she made the hand motion again.

The girl nodded and tried again, flicking harder until the cloth coiled into a rough stone.

"See? You did it! Awesome, dude," Cosima said, going for a high-five. The girl laughed and reciprocated the gesture.

"Um… thank you." the girl said with a smile, quickly turning around trying it again.

Cosima smiled at the girl's enthusiasm, and turned to her own pieces of cloth. By the end of the period, she had perfected the spell, her cloth coiling so tightly that it was shiny.

When McGonagall dismissed them Cosima went to go talk to the French girl again, only to see her walking out of the class with her friends. She sighed and went to go collect her books, when she saw a piece of parchment sitting where the girl was earlier. Putting her books down, she reached over, only to see that it was her schedule for the year. Reading it, she realized the girl also had Charms 4 with her.

She looked down further to see that the girl was taking Potions 6 and an extra session working with Madam Pomfrey in the Hospital Wing.

Cosima quickly grabbed her books and headed towards the dungeons where she would hopefully spot Delphine.

In her transit, she hugged a corner as she switched corridors and ran into a familiar face, sighing when she saw who it was.

"Hey, Cosima!"

She ran past the boy, "Not now Scott, I'm in the middle of something," she shouted.

"But-" she heard him protest, but she ignored him as she descended the side staircase. She was nearing the dungeons when she saw the French girl, talking on the side of the hall with her friends. She seemed to be saying goodbye and turned around as Cosima approached, skidding to a halt in front of the pretty blonde, who looked at her the same way as when she did that before their class.

"Heyy," Cosima drawled.

"Bonjour," the girl responded casually.

"You just- um…" she started, taking out the piece of parchment, "You forgot this in the classroom."

"Oh, umm… thank you," the girl said, taking the paper.

"No problem," Cosima said raising her hands and backing away. Deciding that she didn't want to end the conversation, Cosima turned back around, "F-full disclosure," she started, gathering the girl's attention, "I um… I did peek."

The girl looked at her expectantly.

Cosima blinked, remembering to elaborate, "You're schedule, it's like wicked killer, man."

The girl shook her head, not understanding at all what 'wicked killer' could possibly mean, "Umm…"

"Oh- I meant um… very hard."

"Oh yes, I'm… potions."

"You're trying to be a potioneer?" Cosima elaborated. The girl nodded. "Oh cool, cool. Yeah, I'm in spells."

The girl squinted her eyes, "A spells… inventor?"

"Yeah! Yeah, yeah that's what… yeah." Cosima said, laughing nervously.

The girl held out her hand, "Delphine," she said suavely with a small smile.

Cosima clenched her jaw to keep it from dropping, "Cosima," she managed with a smile, shaking the girl's hand softly.

"Enchantée."

"…Enchantée."
