Mark and Ruby took up stances opposite of each other. Ruby unfurled Crescent Rose as she waited for the signal for the battle to begin. Mark unsheathed Madax Furashada. He held them in his usual grip, with the katana in reverse-grip and the longsword regularly. Ozpin walked into the middle between them.

"I will be refereeing this match. Are you both ready?" Ozpin asked. Both parties nodded towards him. "Begin!"

Ruby dashed forward to Mark with the help of her semblance. She twirled Crescent Rose in her hands to bring it down on Mark's left shoulder. He caught the shaft of her scythe with his katana, before attempting to slash at her with his sword. She blocked the attack with her scythe, while jumping backwards to gain some distance between each other. She took a couple of shots to gauge whether or not he could deflect them to which he deflected each bullet with ease. Mark ran forward to close the ground between Ruby and himself. She dashed away with the help of her semblance. Allowing himself to tap into the power he sealed away with his memories, Mark closed his eyes to focus on activating his aura to access the dust infused inside of him. Tapping into the lightning dust, he charged himself with it. As he opened his eyes, crimson lightning started to crackle around him. He sprinted forward towards Ruby who snapped out of her confusion just in time to dodge Mark's swipe at her with his katana. Moving faster than most people could keep up with, their fight became into a dance, with Mark going on the offensive, while Ruby could do nothing as she tried to fend off the attacks.

Everyone just watched on in shocked silence as they witnessed the fight before them. Barely able to keep up with them fighting.

Yang spoke up. "If we could barely see what's going on, how could Summer even keep him in check?

"Never mind that, how in the name of Dust did is Ruby keeping up with him?" Weiss asked in disbelief.

Everyone grew dead quiet as they heard a crack resonate through the air. They saw Ruby drop to her knees, with Mark standing over her smiling with a demonic look on his face. Weiss watched in horror as she saw Ruby drop her beloved Crescent Rose to hold her broken arm, courtesy of Mark, or whatever he is now. During their fight, Mark had activated even more of his aura to tap into the dust in his body, black flames surrounded his body as white ice grew over certain parts of him to act as armor with the red lightning still crackling around him. His eyes had become full red orbs.

"He resembles a Grimm now." Weiss thought aloud as she watched him approach Ruby, the girl who tried to befriend her even though she treated her like dirt the first time they met, the girl who always cared for her no matter how much she pushed her away, the girl she shared her first kiss with.

"Stop him!" she shrieked. Her yell brought the four adults out of their shock to help Ruby. Siegfried tackled Mark away from Ruby as Ozpin, Taiyang, and Qrow engaged him. Mark was forced on the defensive as he deflected each blow from the four skilled fighters. Weiss ran towards Ruby to help her.

"RUBY, RUBY LOOK AT ME!" Weiss screamed at Ruby as she was on the verge of passing out due to blood loss.

"W-Weiss, what are you doing in my dreams?" Ruby asked shakily.

"This isn't a dream you dolt, don't you dare go to sleep now. You hear me, Ruby, RUBY?!" Weiss screeched.

"Well isn't this cute?" Weiss heard a demonic voice chuckle from behind her. She turned her body to see Mark looking at her, his demonic grin still on his face. "Having a little moment are we? I'd hate to break this up, but I still have a little killing to do."

"What, but how?" she searched for the four adults, only to find them fighting another Mark.

"What, but how?" she repeated.

"My semblance, allows me to create things from my aura, I just created a shadow of myself for them to fight. The real me, the real Mark is right here." he said, tapping his chest.

"No, you're not Mark. You wouldn't do this on purpose."

"Ding-ding-ding, We have a winner, sorta."

"What do you mean?"

"Hmm, how do I put this easily for you to understand? I'm the Grimm side of him, the violent side, the monster inside. Everyone has a monster inside of them, I just gained control for a little bit, so I can kill you all."

"No, you can't hurt her anymore, I'll stop you." Weiss stated as she stood up, protecting Ruby behind her.

"Oh really, and what makes you think you can do that?"

"Summer was able to do it, I can do it as well."

"Ahh, Summer, she was someone I could enjoy a fight with. I miss her. We saw her not too long ago you know. Last night actually."

"W-What?"

"Bah, enough of this," Mark said waving off Weiss' questions. "you can't stop me, no one can. Look over there, your knights in shining armor have just been defeated." Mark gestured to the four adults struggling to stand up as Mark's shadow approached them to deal the killing blow. "I can almost taste the blood." he sighed happily.

"N-No..." Ruby said shakily, standing behind Weiss.

"Ha, prepare to die!" Mark shouted as he attacked Weiss. She barely had enough time to create a glyph to stop his attack. Before she could react, he struck again, breaking the glyph, his hand stopping inches from Weiss' chest.

"W-Weiss?" Mark said, his normal voice breaking through, saddened by what he saw. "I-I'm sorry you had to see this side of me."

It was just enough time though for Ruby to grab Crescent Rose, and thrust the shaft end forward, impaling Mark. With Weiss' help, they threw Mark into the air before twisting the scythe around to cut Mark, from his left shoulder to his right side. He dropped to the floor as he kept his body from falling apart. Mark's face started smiling.

"Looks like I've been bested again, but just barely." Mark's voice took on the demonic side again. "I'll bow to you since you've bested me, but remember, if you can't give me a good fight, I'll be sure to find someone who can." the demonic side laughed as his eyes closed. The shadow that was attacking the adults stopped moving, before melting into a shadow. Mark's upper half surrounded itself in a flurry of black rose petals, which came from the shadow that was fighting the adults, which blew away after a time to reveal Mark standing before them. His aura died down as he opened his eyes. Mark opened his eyes to find the carnage he had wrought before him. He immediately rushed to Ruby's side as she collapsed. He held his hand above Ruby's arm, letting a black glow enveloped under his hand as he healed the wound he had inflicted.

"I'm so sorry..." he kept muttering under his breath as he continued his work.

Weiss just watched in awe as she saw the person who had inflicted this damage be so regretful that they allowed this to happen. The aura that was used to deal this damage be used to mend it.

As soon as Mark finished healing Ruby, she opened her eyes to the sight of Mark crying over her.

"Why are you crying? Don't cry, I know you didn't mean it." Mark stopped his tears before gesturing for Weiss to take his place by Ruby's. As he let Weiss take his spot, he left to heal the four adults that were injured during their fight.

"Ruby, are you okay?" Weiss questioned as she held her head in her lap, tears falling for her eyes.

"I'm fine, don't worry Weiss." Ruby chuckled.

"Don't you EVER scare me like that again." Weiss sobbed as she grabbed Ruby's head to lean down to give her a kiss on her forehead..

Ruby just looked up at Weiss, who was still sniffling. "I promise." The redhead said she sat up to give the heiress a hug.

Yang and Blake ran towards the two after deeming it safe to approach.

"Ruby, are you okay?" Yang said as she rushed to hug her sister. Weiss let go to avoid being crushed by Yang's embrace.

"Y-Yang, can't breathe..." Ruby squeaked out as her sister let go.

Catching her breath, Ruby replied, "I'm fine Yang, I'm more worried about Mark."

"Why?! He hurt you Ruby." Yang lectured.

"No he didn't, I could see it when I was fighting with him, He wasn't in the right mind. Something was in his place. When he fought, I noticed a sadness coming from him." Ruby replied.

"She's right," Weiss said as she stepped forward to help Ruby. "There's another side to him that I spoke with when I ran down here to help Ruby. The violent side of him took over or something. When he spoke, he sounded more, I dunno, demonic."

"Well that's a relief to hear." Ozpin said as he walked towards the girls, with Mark in tow. "I had hoped that Ruby alone would be able to stop him, but alas that cannot be. I'm afraid we may need to send hi-"

"Sir, if I may," Weiss interrupted. "I believe I know why Summer, Ruby, and I were able to stop him."

"Please explain then." Ozpin started.

"When Mark was about to hurt Ruby and I, he stopped for a second, recognizing us. That gave Ruby and I enough time to stop him. I believe he is still able to somewhat control himself when he finds himself fighting someone he cares about. That's why Ruby and I was able to stop him. As well as Summer. We were the only people he opened up to personally."

"That would make sense. I never really cared about anyone on a personal level aside from you three. I also know that that side of me would never purposefully hurt either of you. He was testing you. What did he say, if I may ask?"

"He said that we had bested him, and that he'll bow to us." Ruby said shakily as she stood up. "He also said that he wants a good fight. If not, he'll find someone who can." Ruby stated.

"Is that all?" Mark pressed on.

"As far as I can remember, yeah."

She doesn't remember him talking about Summer? I'll ask him about it later. Weiss though to herself. "What did he mean?"

"He said the same thing when Summer first fought me. He started to listen to me and her. We never lost control again, aside from fits of rage over seeing someone I cared about hurt."

"What do you mean by "we"?" Weiss questioned.

"After he said that he'll bow to someone, he started to work with me to protect the people we care about. He cares about you guys the same way as I do, he just expresses himself differently. He wanted to make sure you were someone worth protecting. I am able to use that power I had just used, only I stay in full control."

"So, we don't need to worry about anymore outbursts?" Qrow questioned.

"No, they stopped after he agreed to work with me to protect the ones we care about. We should be good. I don't have to hold back now if I don't want too."

"I'm more interested about how you can just get up from a injury like that." Weiss stated.

"I can cover myself in my aura, and if that piece gets injured, it hurts my aura, leaving my physical body untouched aside from a scar." Mark stated as he lifted up his torn shirt to reveal a new scar caused by Ruby and Weiss.

"Well that's useful." Yang stated.

"So what did you do to get Mark out of his trance?" Sieg asked.

"Well, we cut him with my scythe to stop him." Ruby stated.

"Yes, but we hurt him as well, why did he not snap out of it then?" Tai asked.

"We dealt a fatal blow to him that he wouldn't have survived without his semblance." Weiss continued.

"Maybe that's how we get you out of your bloodlust." Ozpin stated. "By killing you in it."

"Well that's pretty grim..." Yang joked.

"Indeed it is..." a voice Weiss was all to familiar with said behind Mark. The Grimm side of Mark walked out from behind him, almost like it was his shadow. Everyone held there breaths, anticipating what he would do next.

"That was a lovely fight. I thoroughly enjoyed it, though please quit calling me "he". I prefer Grimm." Grimm stated. "Allow me to apologize for attempting to kill all of you earlier, I wanted to make sure you were worth fighting to protect. I see that you are worth protecting."

"Why did you have to try to kill us to make sure we were worth protecting?" Ruby asked, unfazed by what was unfolding before her.

"Everyone has to die, right?" Grimm asked cryptically.

"Yeah, but what does that have to do with anything?"

"We wanted to make sure that the people who we will be protecting will become capable of killing us later on." Grimm stated.

"Nice joke, but really, why did you do what you did?" Weiss said nervously.

Grimm stayed quiet to reinforce their point. Ruby and Weiss turned to Mark who wore a mask with no emotion on his face.

"Oh..." Ruby and Weiss whispered.

"Enough of that though," Grimm started, "I want to actually kill something, and so does Mark. So Ozzie, got any hunts for us to go on?"

"There are some, but what do you mean Mark wants to kill something as well?" Ozpin asked.

"I'm his violent side, that he usually keeps quiet, doesn't mean that he isn't violent. He craves bloodlust just as much as me, only he keeps it on the down low." Grimm smirked.

"Well that's disturbing...Anyway I'll send you out on a hunt. Get ready, be ready by tomorrow night."

"Excellent, I want Ruby and Weiss to accompany us." Grimm stated.

"Why?" Sieg questioned, concern lining his voice.

"Just so they know what we're capable of when we want to kill." Grimm replied.

"Ok, it's their choice whether or not they want to go. I'll get it ready. Everyone get some rest, its been a long day." Ozpin lectured as he left to retire to his office.

"Alrighty then, who's hungry?" Yang asked.

"Let's go eat at a restaurant, my treat." Sieg said. Yang and Ruby fist pumped, while Weiss and Blake smiled as they left. "You can come as well, you guys." Sieg said to Tai and Qrow. They thanked him as they left to get ready.

"Weiss, Ruby, a moment." Mark called to them before they walked away. They looked confused for a moment before walking back to talk to him and Grimm.

"So we agree?" Mark asked to Grimm as they approached.

"Yes, it seems that it would be for the best. I trust them." Grimm said.

"What's for the best?" Weiss asked.

"Hold still you two." Mark commanded. Grimm walked into Mark's shadow and melted into it. Mark reached out with his hands and placed them on each of the girl's shoulders. His hands started to glow black as he passed his aura to them. They felt a warm feeling wash over them as his aura reached out. After a moment, he withdrew his hands and rested them on his knees to catch his breath.

"What was that?"Ruby asked, as she felt the warm feeling dissipate.

"I transferred some of my aura to the both of you in the way of unlocking one's aura. It will act as a shield for each of you. If you take damage, it'll drain my aura from each of you before it drains your aura." Mark informed.

"You're able to do that?" Weiss asked in disbelief. "Why can't you do that for everyone else?"

"Because," Mark started. "It splits my aura between each person. I gave each of you about 1/4 of my aura to protect you."

"You'll be fine without it?" Ruby said.

"I can hold my own without it, I don't use my aura that much anyway. Now let's get going, wouldn't want you guys to miss dinner."

I had fun writing this chapter. The only problem I feel I had with this chapter was when I had Grimm explaining how he existed with Mark. Aside from that, I felt like this chapter got my point across of how I want to set up Mark as a character. Please review, any criticism is appreciated.
