A/N: I'm really sorry for being late, life got stressful. Plus I probably used up too much creative juice on Guilty Rose, What's left of her, and a few other projects. I'll try to have another chapter out this week, but we'll see how that goes.

I don't own RWBY or RoosterTeeth. I live near where they started, but that's a different matter.

Mithril POV

Well, I guess it's time to tell her the truth. Mithril, Winnie, and Team RWBY were all in Team RWBY's dorm, waiting for Mithril to explain her name. "So, are you going to tell us," Weiss asked while looking rather annoyed. Mithril sighed, "of course I am, I was just giving you one last chance to see the obvious." Winnie did warn me. "Well, I'm gonna go with the bandage method, we are twins," Mithril said while giving a slightly nonchalant hand gesture. Winnie sharply inhaled while the rest of the room was dead silent. "What," Weiss finally shrieked, much to the discomfort of mithril and the raven haired girl, Blake. "But Winter, you and mom, why didn't you tell me," Weiss babbled at her older sister. Winnie sighed and motion for Mithril to fully explain. "Yeah, that's because of an agreement between dad and mom, see, when she gave birth to us she wanted to keep both of us, but ears are a lot harder to hide than tails, so I got passed to dad while mom kept you, they agreed to never tell a soul about this, hell I only found out 'cause Winnie here called me Weiss last year," Mithril explained. Winnie cleared her throat, "please don't call me that, yes, she is telling the truth, after the incident where I refered to her by your name, we managed to piece together the truth and have been waiting for the right time to tell you." "Bullshit, mom told us never to tell you," Mithril laughed, "you should have seen Winnie's face when mom tore her a new one for finding out." "Don't call me that," Winnie chided her. "Now that the cat is out of the bag, can I be an actual sister to Weiss," Mithril Asked Winnie. Winnie cocked an eyebrow, but shrugged her approval. Mithril immediately hugged Weiss. "Ack, too tight, let go," Weiss pleaded. "No, you need a hug, and that bastard needs to beaten to an inch of his life, repeatedly," Mithril loosened her embrace, but wasn't letting go. Weiss looked baffled, but quickly understood what Mithril meant. Mithril took a deep breath and gave one last squeeze before letting go. "By the way, you need to put some meat on your bones, otherwise guys will have nothing to hang on to," Mithril chimed befor darting out of the room. Her exit was quickly followed by two indignant shrieks and a loud laugh. Now I have two sisters to mess with. Mithril smiled to herself as she wiped a tear away.

.Time Skip to Later That Night

Sterling POV

"Why," Sterling growled while staring at the form on his bed. "Because I insisted," Mithril shot back from his bed. Sterling scowled at her. My opinion of Ozpin is reaching dropping even further. Sterling sighed and returned to scrolling through news articles, more out of habit than not. "Why did you make sure Ozpin gave me asylum," Mithril broke the silence this time. Sterling stopped and stared at his desk. "I never wanted you to be involved in what happened that night," Sterling sighed again, "Winter promised that you, and her, would be safe." The bed creaked as Mithril adjusted her position. "You are seriously more worried about me than yourself," Mithril giggled. Sterling put his scroll down, "it's hard to worry about yourself when you've been turned into an abomination." Mithril was silent for a moment, "it's hard to believe what they did to you."

"The experiments were supposedly to produce soldiers capable of turning the power of grimm on their own kind," Sterling spoke with disgust. "I was recruited because my original semblance was conducive to their needs, at first, I was honored, then they began pumping grimm blood into my veins," Sterling continued, "eventually, the experiment succeeded, and I was corrupted." Sterling clenched his fist, "when I learned they planned to perform the experiment on others, I couldn't just stand by."

"Not really, I was some random faunus who suited the needs of their experiments," Sterling sighed. Mithril growled but didn't say anything. After a few moments, Mithril spoke up, "You said you were corrupted, what does that mean." Sterling chuckled soberly, "I was a woodland wolf faunus before the experiment, now, you could say I am a beowolf alpha faunus." "What," she gasped to the amusement of Sterling. "I grew a tail and my hair turned black, apparently people don't notice because I also picked up habits of beowolf alphas as well," Sterling answered. Don't forget, the more grimm I absorb, the more I turn into one. Sterling let out a sigh and got up. "Well, I've got the day off tomorrow, and I have several matters to attend to," Sterling said while he stretched. Mithril took this cue to take a seductive pose, "then why don't you join me in bed." "No," Sterling deadpanned. Mithril pouted a bit. "Goodnight, Mithril," Sterling dismissed the woman in his bed while he laid down in a spare bed meant for Mithril.

Mithril POV

He's so much different than before. Mithril looked over at the bed Sterling was in. Always the serious one, but then again, he did have that experiment performed on him. Mithril recalled all the times she saw him in Atlas. He always had that same cold expression. Even when she met him during his escape, he had that same expression. It does look good on him. Mithril blushed lightly at that stray thought.

Ozpin POV

Ozpin was trembling with a variety of emotions whie sitting in his office. Only she could think of such a twisted plan, turning humans into grimm. Ozpin wanted to call Ironwood to Beacon so he could beat the man himself for what he had done. No, he was lied to as well, how could he resist soldiers that could use any enemy's power against them. Ozpin seethed again. How could I let this happen.

..Time Skip to the next day

Sterling POV

Sterling Managed to get through the morning with only minor harassment from Mithril. Apparently, she was both a light sleeper and a terrible morning person. He added a coffee machine and coffee to his list of things to get. Why did Ozpin agree to put her in my room. Sterling mused on the enigma that was Ozpin's mind and Mithril's stubborness. He always knows more than he'll ever tell, even when they need to know. Sterling growled loudly to himself, startling a few of the people around him on the sidewalk. He realized what he had done and shuffled onward to a bar owned by a man named Junior.

A/N: So, what did you guys think. Fluff, plot, and fluffy plot all in one chapter. The story thickens with both Sterling's past and the fact that Mithril is Weiss' twin sister, fraternal by the way.

I got to say, I really enjoy writing Mithril, I hope you guys enjoy reading her antics.

I hope you guys enjoyed reading this chapter!

Until next time!

Please review and follow!

P.S. about the paragraphing, I like writing it like an American novel, it's more natural to me. Guilty Rose will not be like this though. So for those who have a hard time reading big paragraphs, don't worry!
