Here's a little story that I will be updating the next couple weeks. I just really wanted to write a jealous Blake and...this is what came out of that! It won't be terribly long (it's only about 20k words), but hopefully everyone still enjoys it! Read and review :) Reviews make me happy!

(Also, I know that we have no idea if Winter is older or younger than Weiss, but I figure that I had a 50/50 chance of being right here.)

"Come on, I could totally take Pyrrha in a fight and you know it!"

Blake laughed, shaking her head at her partner's claim while they made their way through Beacon's hallways towards Team RWBY's dorm room. The two of them had just finished studying together in the library and were finally prepared to turn in for the night.

"I don't know, Yang…Pyrrha is a very, very experienced fighter. No one in class has been able to defeat her yet."

"Psh…that's just because she hasn't fought me yet!" Yang replied confidently.

Blake decided not to comment, opting instead to laugh at Yang's self-assuredness. It was one of the traits that made Yang definitively…well, Yang.

In the time they had been together as partners, Blake had never once been bothered by Yang's boasts – because underneath the surface of sureness lay a modesty and willingness to sacrifice for others that Blake truly valued.

Of course, Yang refused to let the subject drop that easily.

"I'll prove it to you! I'll challenge Pyrrha next class!" the blonde proclaimed, instantly causing Blake to raise an eyebrow in surprise.

"You mean that you'll actually choose someone besides me for once?" she asked in amazement, holding one hand over her heart in mock hurt. It had become something of a running joke between them by this point, since Yang would choose to spar against Blake each and every time she was given the opportunity to pick her opponent – a fact that did not go unnoticed by everyone else in the class.

Yang laughed in response to Blake's act while she ran one hand absentmindedly through her gorgeous mane of long, golden locks.

"Well…you know…I just like for everyone in class to see what an amazing fighter you are," she replied with a smile.

Blake rolled her eyes, although her heart did not fail to speed up at the unexpected compliment.

"And you like for everyone to see when you beat me," she added helpfully.

"Ah…you might have me there," Yang admitted, turning to send her a good-natured wink.

Blake playfully shoved her partner's shoulder, causing Yang to bump into the hallway wall.

"Then why are you a completely poor sport when I win?" Blake chastised the blonde, making Yang hang her head in shame.

"But it's ok, since Pyrrha is going to completely wipe the floor with you," she finished with a smirk. Yang instantly regained her swagger, giving Blake a beaming smile that was sunny enough to melt Weiss' sturdiest icicle.

"Dream on, kitten," Yang replied, using the unfortunate nickname she had settled upon for Blake (although it still made her blush every time Yang used it). "When I defeat Pyrrha Nikos, I'll expect to collect a hefty reward from you!"

She shrugged her shoulders in response, not at all concerned with the proposition of losing.

"Sure, why not. It will never happen anyway," she replied nonchalantly.

Just last week, they had watched Pyrrha demolish the entirety of Team CRDL in a matter of minutes - for what must now be the twentieth time. The four boys seemingly could not get enough of Pyrrha's ferociously dished out punishment. There was no way Yang was going to win this bet.

But Blake's agreement caused Yang to let out a loud whoop of excitement anyway as she raised her fist in the air in delight.

"You've got yourself a deal, Belladonna!" she cried out eagerly, just as they reached their dorm room.

As she always did, Yang rushed forward and opened the door, giving Blake an exaggerated bow that caused the Faunus to laugh and roll her eyes while walking inside.

She immediately cut off her laugh when she sensed the unhappy atmosphere hanging over the room. It didn't take long to pinpoint the source of the mood - a certain heiress sitting shell shocked upon the edge of her bed. Ruby was settled beside her partner, slowly rubbing the girl's back in what could only appear to be consolation.

"Woah, who died?" Yang asked as soon as she had stepped into the room, swinging the door shut behind her. When the blonde stopped by Blake, she jabbed one elbow into Yang's side and nodded her head meaningfully towards Weiss.

"What's wrong, Weiss?" Blake asked in a much softer tone, trying to make up for her partner's less tactful approach.

The heiress sighed and responded without even glancing up at them, content with staring down at her scroll.

"Winter's coming."

Yang promptly laughed.

"I don't know if you've looked outside recently, but winter is kinda already here, Weiss," she commented as she pointed out the window, where a fresh layer of snow could still be seen laying upon the Beacon grounds.

Weiss sighed again while Ruby looked up at her sister with a frown.

"She means her sister, Winter," the brunette informed them. "Not the season."

"Oh."

Yang mouthed the word 'oops' towards Blake while the silence of a mausoleum enveloped the room once more.

"So…when is she coming?" Blake asked, finally daring to break the increasingly uncomfortable silence.

Weiss hardly ever spoke of her family, so Blake didn't know much about Weiss' sister. But based upon the heiress' mood right now, she could imagine that their relationship was rocky, at best.

"Well, thanks to her refusal to inform me of anything with enough time to make adequate plans, she'll be here tomorrow evening. And, since she procrastinated so long, all of the nearby lodgings are completely booked since it's so close to the holidays."

"Uh…then where will she stay?" Yang asked curiously, causing Weiss to heave another big sigh before finally turning towards them – crystal blue eyes seeming to be asking for their forgiveness.

"With us, if you're all ok with it."

Ruby immediately began nodding her head enthusiastically.

"Of course we're ok with it! Right guys?" Ruby replied, sending Yang a glare that said her sister had better agree with the proposal and not make things any worse.

"Y-yeah! I mean…sounds great!" Yang replied hastily. Blake nodded her head in agreement with the two sisters, hoping that this would at least make Weiss feel slightly more relaxed about her sister's visit.

And Weiss did look visibly relieved upon receiving their approval, relaxing back into Ruby's loving embrace.

"Thank you," she said softly. "She'll only be here for a few days so it shouldn't be too much of a hassle. And I'm sure the school has an extra bed we can squeeze in here…somewhere."

The four girls glanced around their already crowded room, each wondering what it would be like with a fifth person joining them. Eventually, Yang just shrugged at Blake and headed over to put her items away from studying.

It was only going to be a few days. What was the worst that could happen?

That night, after Ruby and Weiss had already fallen asleep, Blake was still sitting on her bed reading by the soft light provided by a sole bedside lamp. For the average person, it wouldn't have been nearly enough light to read by, but with her superior night vision, the words were still crystal clear on the page. Quite a benefit when living with a particularly fussy heiress...

She would often read at night after her teammates had gone to sleep – she always had one book or another to catch up on. But mostly she stayed awake because around now was when…

"Hey Blake?"

She paused mid-sentence and smiled when she heard the whisper come from above her. Turning her attention away from her book, she looked towards the bottom of her partner's bed while listening to the sounds of covers shuffling about above her. Seconds later, Yang's face came into view as she hung her head over the edge of her bed, peering at Blake upside down while her long golden hair dangled towards the floor.

The blonde grinned when she found that Blake was still awake and quickly swung herself off of the bed, dropping almost noiselessly to the floor.

"Impressive," Blake remarked sincerely, while scooting closer to the wall in order to make room for her partner to sit next to her on the bed.

Months ago, she had had to teach Yang how to land more quietly after the brawler had landed on the ground with an exorbitantly loud thud one too many times – earning herself the ire of a certain short-tempered heiress.

Weiss had threatened to have the girl's feet removed the next time she was woken up in such a manner, so Blake had forced the blonde to work with her after classes. Thankfully, Yang was quick to learn and an absolute pleasure to teach. Before too long (and not nearly long enough in Blake's mind), she was landing soundlessly on the balls of her feet, much like Blake did.

"Thanks!" Yang whispered, crawling underneath the covers. Blake felt her heart begin to race when Yang's arm brushed gently against her own - blushing when she thought about her partner's bare skin touching her so casually.

But she cast that thought out of her head almost as soon as it appeared, not wanting to get distracted by those…feelings…once again.

Yang had become comfortable with crawling into Blake's bed very early into their partnership - much earlier than Blake had been (if she ever would have been at ease with that, at all). But, as with many things Yang did, Blake had learned that sometimes objecting would lead to something even more embarrassing or uncomfortable happening.

As proof of this, she only needed to recall one of the many instances when Ruby had tried to tell her big sister 'no.'

The blonde just didn't take 'no' for an answer. At least, not very easily. So Blake hadn't spoken out against her partner invading her personal space, opting instead to scoot uncomfortably away from the girl on her own bed while the blonde would chatter incessantly.

But now, she was glad that she had never said anything since she rather enjoyed when Yang would drop down and spend some time talking to her before they would go to sleep. The time spent, just the two of them, reinforced her feelings for her partner – helping Blake grow closer to Yang than to anyone else she had ever known.

Still, it never failed to make her heart pound to have the stunning girl sitting so closely to her. She couldn't help but think of how many of the boys in their classes would kill just for the chance to experience this for even one night. Of course…Blake got to do this every single night…something she was both incredibly honored and protective of.

"What do you think Weiss' sister will be like?" Yang asked after she had made herself at home in Blake's sheets, her above-average body temperature already creating a nice, warm pocket of air surrounding them.

Blake closed her book, making sure to keep one finger placed between the pages to mark her place, before turning towards her partner.

Thanks to Blake's night vision, she could see Yang clearly even in this low light. And from the minimal distance in between them, Blake could say with complete certainty that Yang was far more beautiful than anyone else even knew. Sure, everyone already spoke of Yang as one of the prettiest girls in the school, but Blake could say without a doubt that Yang's beauty went far beyond anyone else she had ever seen. It was as if...the blonde glowed from within.

And recently, the blonde seemed to have been growing increasingly more gorgeous – something Blake would have never even thought to be possible if she hadn't been the one seeing it with her very own eyes. But this had made it even more difficult for Blake to look at Yang without a flush racing quickly to her cheeks.

"I think…" she began slowly, turning her eyes briefly away so that she could form some sort of coherent and intelligent thought that wasn't about how beautiful Yang was, "she is probably very similar to Weiss. They were brought up by the same parents, after all."

"Yeah, but they don't seem to get along very well!" Yang replied.

Blake scoffed lightly at the rebuttal.

"What sisters do?"

Yang's only reply was to point one finger towards herself while directing another towards Ruby's bed with a crooked smile.

"Ok, but you two are the exception, not the rule," Blake hastily replied, realizing that she had already lost this argument.

"But if they don't get along…wouldn't you think they'd be different from one another? Have different beliefs and stuff?" Yang asked - not combatively, just…curiously.

Blake thought about that for a few seconds before nodding her head.

"Maybe…but, honestly, could you imagine Weiss getting along with anyone before she got stuck with us? You saw how she reacted when Ruby was selected as team leader, after all."

Yang laughed quietly, the sound ringing like music in Blake's sensitive ears.

"I guess you're right," she replied. "What am I saying? Of course you're right; you're always right!"

Blake felt her ears twitch with happiness at the proclamation; the tiny movement not going unnoticed by her partner.

"What are you going to do about…" Yang gestured towards Blake's feline ears, causing them to twitch once again.

"Well…I guess that I'll just be wearing my bow in our room for a few days…" she replied, feeling pretty forlorn about the prospect. She had really grown accustomed to the freedom of being able to be bowless – at least while in the privacy of her own room.

When her teammates had first discovered that she was a Faunus, they had told her that they would support however she decided to present herself to the rest of the school - but insisted that within the confines of their own room, she be herself.

"That sucks," Yang replied bluntly, adding an adorable pout for Blake's plight.

"Yeah…but it's not worth getting her all riled up if she feels about Faunus the way her father does," she replied, appreciative of Yang's sympathy for her feelings. It had been Yang, after all, who had pushed hardest for Blake to ditch the bow when they were alone.

She noticed Yang observing her ears intently, looking almost as if she wanted to reach up and touch them.

"I'm going to miss seeing those cute little ears though!" Yang replied with a big grin.

Blake smiled in return. She knew that Yang really liked her ears. And, personally, she loved it when the blonde referred to them 'cute' or 'adorable.' It was almost as if Yang was calling her cute and adorable.

"Alright, well I'll leave you be now," Yang suddenly said, giving Blake's knee a light pat through the covers before she slipped out from underneath them and stood up.

To Blake, this was always the worst part of her entire night.

When Yang would leave, the warmth would begin dissipating almost instantly – providing an obvious reminder that the girl was no longer sitting beside her. It would be one thing if Yang left and the warmth remained to keep Blake company, but losing both at once was always disappointing in a way Blake couldn't even begin to describe. But she could never think of a good way to ask Yang to stay without seeming…well, without it being weird.

And even if she could think of how to ask, she would never be able to gather the courage to actually follow through.

"Goodnight, kitten!" Yang whispered before hauling herself up onto her bed, making hardly any noise at all as she disappeared from Blake's view.

"Goodnight, Yang," Blake whispered in response, listening to the sounds of her partner getting settled back into her own bed.

A soft sigh unconsciously passed her lips as she opened her book to where she had just left off.

The next evening, she was standing with Weiss and Ruby outside the grand front entrance of Beacon, anxiously waiting for Winter to arrive. Yang was supposed to be there too, but the blonde must have gotten caught up in something and was running late. Which was hardly unusual for the girl, but still, Blake knew that Weiss would probably scold her for it later.

The normally composed heiress was broadcasting her nerves for everyone to see - fidgeting with anything she could get her fingers around: her clothing, her hair, Ruby's hand…

"Why is your sister visiting, anyway?" Blake decided to ask, realizing that they had never been given a reason last night.

"Honestly, I have no idea," Weiss answered with an annoyed huff. "She just left me a message saying that she would be here at this time and not to be late coming to get her. I doubt she has any reason at all other than it was her current whim and she enjoys disrupting my life in anyway possible."

"Wow…" was all Blake could say in response. It sounded like Winter was certainly going to be…difficult to please.

"And this would be her. Late, as usual," Weiss muttered in displeasure, nodding towards the decadent black town car approaching them.

Several seconds later, the car pulled to a smooth stop in front of them, allowing the chauffeur to jump out and walk around to open the back door. Blake and Ruby watched in avid interest as Winter Schnee stepped from the vehicle.

If Blake were forced to use one word to describe Winter, it would have to be – stunning. The girl appeared to be a couple of years older than them, or at least she gave off an air of being older. She was taller than Weiss, closer to Blake's height or maybe even taller. Her hair was stark white, just like Weiss', but fell in long, perfectly sculpted waves rather than straight lines.

And, shockingly, she seemed to be even more elegant and poised that Weiss, which Blake wouldn't have even believed to be possible before three seconds ago.

Maybe most surprising of all was that as soon as Winter's piercing blue eyes found Weiss, she broke into a huge smile, which was, by itself, nearly too radiant to look at.

"Weiss!" Winter exclaimed, walking quickly over to wrap her stiff sister in a strangely polite hug. She then held Weiss away by the shoulders and looked her up and down. "It's great to see you!"

Weiss didn't seem at all taken aback by Winter's merry greeting, while Blake and Ruby were still busy trying to collect their jaws off of the pavement in astonishment.

"Winter…good to see you're still doing well," Weiss responded plainly, evidently nowhere near as happy to be back in her sister's presence as Winter was.

"Oh, and these must be your teammates?" Winter asked when she finally noticed the two other girls standing there, still completely flabbergasted.

"Yes, this is Blake, and this is Ruby," Weiss said more animatedly as Blake and Ruby nodded their heads when Weiss introduced them.

"It's very nice to meet you," Ruby said politely, bowing her head slightly.

"You as well," Winter replied graciously, reaching out and shaking both of their hands in turn. She flashed a disarmingly charming smile when she shook Blake's hand, only succeeding in reminding Blake of someone else she knew…

Winter turned away as her chauffeur placed her luggage on the sidewalk beside her. "Thank you, Marshall. I'll see you in a few days."

The man tipped his hat politely before turning away from them. Blake could have sworn she heard the man heave a huge sigh in relief while he walked away, but brushed that off as just her imagination.

"So, where will I be staying?" Winter asked lightly. Blake glanced quickly at Ruby, suddenly feeling uneasy about what was to come.

Weiss also appeared to be much more insecure than usual when she answered.

"You'll be staying with us in our room."

At first, there was silence. Then something worse than silence emerged.

"You expect me to stay in a dorm room?" Winter remarked incredulously, her smile now completely gone from her face while she leveled a withering scowl at her sister.

"Yes," Weiss replied firmly, the strained effort of attempting to hold her ground showing in her slightly imperfect posture. "Since you gave me such short notice, everything else in the area had already been booked."

"You're a Schnee," Winter sneered towards the girl. "Or, at least, I thought you were. You could have easily bought an entire building. Or convinced someone out of their room, if you were really creative."

"Sorry, I didn't feel like ruining someone's vacation just for you to have their room," Weiss shot back. "And since I'm not 'daddy's little angel,' I don't just go around buying hotels."

Winter rolled her eyes and straightened up to her full height, crossing her arms firmly over her chest.

"Well, you'll have to figure something out because…"

"Hey guys! So sorry I'm late."

Yang screeched to a stop beside them, placing her hands briefly on her knees and breathing heavily from what must have been a very long sprint across campus to meet them.

"Professor Goodwitch made me clean all of the boards in her classroom since I…"

The blonde abruptly stopped talking when she realized that everyone was staring at her, including a new set of eyes.

"Oh, sorry, didn't mean to be rude," Yang remarked as she turned towards Weiss' sister, extending a hand with a warm smile.

"I'm Yang. Fourth teammate on Team RWBY and big sister to that little critter over there," she said, using her other hand to point towards Ruby.

Winter stared at Yang for several seconds with an expression that Blake couldn't quite put her finger on, before a big smile reappeared on her face – the girl's attractiveness back in full force.

"Winter Schnee," the girl replied as she reached out and shook Yang's hand, hanging on for a few seconds longer than what might be considered normal.

"Uh…nice to meet you, Winter," Yang responded in confusion when the girl finally let go of her hand. "So, do you guys want to take Winter's stuff back to our room and then grab a late dinner?"

"Actually…" Weiss began.

"That sounds lovely," Winter cut her sister off, flashing a dangerous smile in Weiss' direction before turning back towards Yang. "Please lead the way."

Yang looked at Weiss curiously before she shrugged and easily picked up Winter's luggage, even though it looked like it weighed a ton. The blonde shot a quick smile towards Blake that said, 'see? look how well everyone's getting along.'

Blake smiled back, but her face fell when she noticed how keenly Winter was watching Yang walk in front of them, fervent eyes roving up and down the blonde's figure. After several seconds, Winter sped up and fell into step beside Yang, the two girls chatting amicably while they headed through Beacon's front gates.

Falling back, Blake walked next to Weiss and Ruby.

"Uh…Weiss…" Blake began as she closely observed the two girls in front of them, feeling the hairs on her arms stand on end when she watched Winter laugh and playfully swat at Yang's shoulder.

"That went much better than expected," Weiss replied with a sigh, picking up Ruby's hand while they made their way back to their room.

As she looked back towards her partner, she wondered if this could possibly be 'better' when she felt so horrible at this moment.
