"Come on, Weiss. I promise I'll be careful with it," Ruby pleaded.

"No," Weiss deadpanned. Weiss was beginning to regret her decision to lend Blake some of the experimental elemental rounds that Schnee Dust developed during their last mission. Weiss was losing track of how many times they had gone through this conversation.

"But you're still letting Blake use them," Ruby continued to push.

"Ruby, Blake uses small rounds that, should they fail, aren't going to seriously hurt anyone. You on the other hand, made a small cannon. Its simply too risky," Weiss said, turning around to return to her studies.

At that moment, Yang entered the room. "What's got the Ice Queen so worked up?" Yang asked.

"Your sister refuses to understand that I won't lend her potentially dangerous ammunition," Weiss answered.

"Would now not be the best time to ask if I can have some of those fire things you gave Blake last mission?" Yang asked, smirking widely.

"I hate you all," Weiss said, though she clearly was just expressing her frustration and held no real animosity, "I'll ask my father, but I assume that you're gauntlets use too large of a calibre for it to be safe."

"Weisssss," Ruby whined, "How come Yang can have it?"

Weiss closed her book and began walking toward the door, "I don't think Yang will be using elemental dust rounds. If anyone has an actual reason to talk to me, I'll be in the library."

Ruby stared after Weiss, but even Ruby's love of weaponry couldn't convince her that continuing to pester Weiss was a good idea. She sighed and sat down on Yang's bed.

"Don't worry sis, you'll be able to use them once they are done testing," Blake said.

Ruby looked to be deep in thought, before leaping up. "Hey Blake, can I borrow some of the ammunition that you don't want," Ruby asked.

Blake stared at her over the top of the book, "Please don't tell me you're going to add another gun to your scythe…" Ruby stared at her innocently "Fine I'll lend them to you. I don't want to know what you're planning, so that I can plead ignorance once Weiss finds out." Blake passed her an unopened box of elemental rounds, which Ruby eagerly took before blinking out of the room with her semblance.

:::::::::::::::::::::::::::

Ruby used her semblance to leap around the forge, grabbing the parts she needed. .950 shells, some fire dust for propulsion, a funnel. She set down her load near a press, and set to work opening all of the elemental rounds. She quickly got the process down to a science. Remove bullet from the 10mm rounds; pour dust into .950 round. After emptying the entirety of the box, Ruby had made 12 rounds for her sniper rifle. Ruby was slightly worried that she couldn't tell which kind of dust was which, whatever had been done to make the dust ammunition worthy had bleached it of its original color, but she was sure that it would still work out fine.

"Alright, time to show Weiss," Ruby clapped her hands together, "She won't be able to say it's too dangerous if she sees it work."

:::::::::::::::::::::::::::

Ruby went back to the dorm to find the WBY of Team RWBY sitting on their beds doing various activities. Weiss was studying, Blake was still on her book, and Yang was lying down complaining about the heat. Seeing as she wasn't interrupting anything overly important, Ruby said, "Weiss, I have an announcement."

"Yes, Ruby," Weiss responded, not looking away.

"I've made my own elemental rounds..." Weiss makes a spluttering noise "to prove that their safe enough for you to let me use your company's," Ruby declared.

"And you're certain your… homemade… weapons are safe," Weiss asked.

"Yep, I took the dust from Blake's ammunition and put it some rounds for my rifle," Ruby said.

Weiss's eye began to twitch erratically.

"Tonight, I'm going to use some of them for the first time," Ruby said happily, "And you're going to be there, so you can see how well it works."

Yang had taken an interest at this point, and got on her scroll.

Come to Team RWBY's dorm after dinner if you want to see Weiss have an aneurism. Ruby made some incredibly unsafe weapon and wants Weiss to be there when she tests it.

"Ruby, why would I agree to be there when you blow yourself up?" Weiss questioned.

"Because I want to prove that it's safe Weiss, and you need to be there to do that," Ruby whined. When Weiss continued to stare her down, Ruby made to continue but was stopped.

"I will be there, but only to make sure there's someone there to make sure you don't hurt yourself," Weiss stated.

"Aw thanks, Weiss," Ruby said, leaping forward to hug the heiress.

"Gah, NO Ruby let go," Weiss yelled to no avail, "Let me go, you dolt. Down... Ugh, any help Yang?"

"But you two are such a cute couple! How could I ever interrupt your romance?" Yang said.

Ruby effectively threw Weiss away, blushing madly. Weiss froze, also blushing, and crashed into the bed. Once Weiss had recovered, she requested, "As effective as that was, could you employ different methods in the future?"

"Nah, this way is more fun. Plus its true," Yang responded.

Weiss looked over for help from Ruby, but discovered her partner was still in shock. "Send me a message when you're ready to fire your… ammunition," Weiss said.

:::::::::::::::::::::::::::

Winter stepped off of her family's Bullhead and onto the grounds of Beacon Academy. Officially, she was here to participate in the tournament, which she would do to the best of her ability, but Winter was more looking forward to seeing her sister. Their father had insisted that Weiss not attend the same school as Winter, so that Weiss couldn't "rely on her sister to do the work for her" to use their father's words.

Regardless, they were going to be together for a couple weeks until the tournament came and went, plenty of time to make up for all of the time the sisters had spent apart. Winter idly wondered if Weiss had ever relaxed; Weiss had always been too high-strung, but maybe school had mellowed her out a bit.

:::::::::::::::::::::::::::

Ruby had said she was going to try out her ammunition that night, but, well, there was no reason to not do it now. She opened up her scroll to send Weiss a message: "I'm going to use the elemental ammo. Are you ready right now?"

:::::::::::::::::::::::::::

Weiss heard her scroll ding and saw Ruby's message. Come on, Ruby; you said you were going to wait till tonight not 5 minutes ago. She sent a message back: "Fine, I'm not doing anything I can't come back to." She got up to head out, calling back to Yang as she went, "I'll send you a message if your sister hurts herself too badly."

"Alright," Yang called. Once Weiss had left the room, Yang reluctantly got up. "You want to come Blake?"

"Nah, this is more your thing," Blake responded.

"Alright, I'll go ask JNPR," Yang said as she left the dorm. "Hey, anyone want to watch Ruby and Weiss with me?" No one responded. Presumably they were in class at the moment. Oh well.

:::::::::::::::::::::::::::

Winter knew that her sister's team was called RWBY, and had used this information to look up which dorm Weiss lived in. Winter got slightly turned around in the first year dorm complex, but arrived at the door without much issue. She knocked on the door and was greeted by a black-themed girl. "Hi, is my sister Weiss here?"

Blake didn't recall Weiss ever mentioning having a sister, but the lady in front of her certainly had a strong resemblance. After a moment of debate, Blake decided there wasn't any harm in taking this stranger's word for it. "Weiss is down in the training rooms with Ruby. You might want to wait for them to come back though," Blake suggested.

"What are they doing?" Winter asked.

"Basically, Ruby's going to blow up some dust but will be fine; Weiss will get really mad at her for putting herself at risk. They'll argue back and forth, and Yang will pop out at some point to try and tease them about being a good couple," Blake explained, "It's going to be a trainwreck."

"Sounds like fun," Winter said, "Do you know what room they're in?"

"Not exactly; just look for a girl with a lot of blonde hair," Blake said.

"Thanks, see you around," Winter said.

:::::::::::::::::::::::::::

"Is there anything I can say to convince you not to do this?" Weiss asked, exasperated.

"It'll be fine," Ruby said for the umpteenth time, "Even if it does blow up, I've got enough aura that I won't get hurt."

Listening against the wall, Yang was growing increasingly frustrated. Neither of them were saying anything worth recording, and it didn't sound like there was anything worth rushing in for. All in all, this was beginning to look like a waste of time.

"Alright, it's all loaded up," Ruby said happily.

Winter rounded the corner and saw Yang leaning with her ear pressed against the wall. She looked quizzical for a moment before realizing what the blonde was doing and moving over to join Yang in listening in.

Yang was broken out of her focus by the Weiss lookalike who just showed up and joined her. Looking closer, the girl wasn't exactly the same: cooler hair, bigger boobs, taller. A very attractive woman, if Yang was honest.

Winter noticed the dumbfounded look on Yang's face and decided to try and clear things up, "I'm Weiss's sister; what's happened so far?"

"Ah, ok; Rubes, er Ruby, was about to test it," Yang said, "Um… are you alright with me teasing Weiss?" Not that Yang was going to be stopped, she just wanted to know what side Winter was on.

"Only if I can join in," Winter said.

Yang nodded; Winter and her were going to get along just fine.

BANG… POW POW POW

And with that, Ruby's self-made ammunition failed catastrophically, to the great surprise of no one involved except Ruby.

"NOOOOO!" Ruby screamed.

"Ruby! Are you alright?" Weiss shouted, running into the smoke the explosions caused.

"Crescent Rose is hurt," Ruby said, "We need to fix it."

"Are you kidding me!? Don't scream no so dramatically after something has exploded; I thought you were hurt," Weiss screeched.

"Are they dating?" Winter asked Yang.

Yang smiled devilishly, "Why not ask them?"

Winter entered the training room without hesitation, before thinking better of it. "Wait, I really don't want to ruin this for them," Winter said.

"They aren't dating; I've been trying to push them together, but haven't had any luck yet," Yang responded.

"I'm not sure about Ruby, but Weiss definitely has a crush," Winter said, "And Weiss won't do anything with it if I'm not careful about setting them up."

"Is she really? This is perfect! Ruby's been crushing for forever, but I figured Weiss was just oblivious. I guess Ruby would never do anything with it either," Yang said, "Ah, but I hate giving up a chance to tease them; alas, it's for the greater good.

Inside the training room, Weiss was looking apprehensively at the doorway. "Did you see Winter in the door a second ago?" Weiss asked Ruby.

"Is your sister here? Ooh I want to meet her," Ruby said, "But first, I'm going to fix my sweetheart." With that, Ruby left the training room. Winter and Yang ducked around the corner to avoid being seen.

"I thought you said Ruby had a crush on Wiess. Who's her sweetheart.?" Winter asked accusingly.

Yang laughed, "Make that 'what's her sweetheart'. She has a pet name for her sniper-scythe."

"Seriously?" Winter said.

"No joke. That weapon is Weiss's main competition," Yang said.

"Alright, how about we reconvene in your dorm room and we'll figure out how we're going to get our little sisters together," Winter suggested.

"Shall we?" Yang said, jokingly offering her arm to the Schnee sister.

"So we shall," Winter said, slipping her arm into the blondes.

Yang's heart sped up a bit from the unexpected proximity. She found herself focusing on every touch as they moved through the hallways. Yang knew too much about love to miss what was happening, but that didn't mean that she expected it. For the moment she was determined not to react, and hope that it didn't get worse. It was one thing for Weiss to fall for her adorkable sister, but there was no way that such a beautiful, elegant but still fun, sma… "Shit," Yang whispered. She was falling hard enough to already be rambling.

For the people in the 4chan greentext thread asking for the Winter and Yang shipping Whiterose fic, resident writefag reporting for duty. Winter may not have a single line of dialogue in the show and we know nothing about her personality, but that doesn't mean that I can't ship the older sisters together. I'm not sure if the primary focus of the story will be Whiterose or the newly christened Frostburn (Winter/Yang) so there will be a poll on my profile to decide. This is going to be my first romance fic, so any tips or tricks you can offer are greatly appreciated. This chapter doesn't have much on the romance front and is more to set up the scenario for the rest of the story, but I still enjoyed writing it. As always, thanks for reading and please review. Hope everyone enjoys.
