Stiles stayed with Oliver that night, you could say that it was fun for the two of them. Stiles was surprised by his sudden outburst of confidence. Morning came and gone, Stiles knew the fun time had to end eventually.

Oliver dropped Stiles off at his house, fully clothed thanks to him. Stiles' care was still in the driveway. Did she even go out to look for me? Stiles thought to himself as he said his goodbyes to the man in the drivers seat.

"Goodbye, love, I'll see you Friday at 8." Oliver grinned pecking Stiles' lips.

"Bye, Oli," Stiles exited the car, instantly getting hit with questions as she came out of the house. Her face bright red with anger.

"Where the hell have you been? I've been trying to call you." Stiles just rolled his eyes, brushing past her going into the house. Oliver pulled out of the driveway, knowing this was a family moment and left.

"My phone is upstairs in my room, you dumbass. I was out with a friend anyway, I wouldn't answer you." the words flew out of his mouth, he was shocked himself that he was so harsh to her. It felt like it wasn't even him saying that. No, he wouldn't say that, it wasn't him who said it.

"By 'friend', do you mean lover?" Stiles stopped in his tracks. "I can see the hickey's littering your neck. The jacket he lended you doesn't cover much."

The hazel eyed boy felt as if he had no control of the words coming out of his mouth or his body. He couldn't stop them from coming out. "Oh shut up, you bitch." he turned around, his hand coming up from his side and his hand touched her cheek before he could try and stop himself.

Emma gasped, the anger vanished and it was replaced with betrayal and shock. Stiles has never hit her, not intentionally or even call her names as bad as the ones he just called her. He's called her stupid, idiot, stuff like that when they were playing around but never 'dumbass', or 'bitch'.

"Did you just-did you just hit me?" she stuttered, she hadn't even fully grasped onto the fact that he hit her.

"Yes, I did, got a problem with that?"

Emma tried to speak, but she had no words left to say. Her gaze dropped to the floor and a soft sigh escaped her lips. She began to walk away without saying anything, and she walked up the stairs, tears brimming her eyes. She refused to let them fall while she was still in his sight.

The blonde eventually reached her room and took a seat on her bed, the tears falling down her face. He has never done that before. Emma missed the old him, the funny, optimistic Stiles. Ever since the whole thing with Barry and the kidnapper went down, he's completely changed. He's...grump, sad...he feels guilty for killing that man. She would have felt the same way, but she would have moved on by now.

The way he acted yesterday was unbelievable. She knows it's hard for Stiles to see Barry since Barry was in love with Iris, but his actions were uncalled for. He's never yelled that way either. Stiles has always hated yelling.

Emma jumped hearing her phone go off, indicating she had a new message. She wiped away the tears, getting up and strolling over to where her phone laid. The blonde gasped.

unknown: Think back to what I said, Emma...you are slowly losing him. He is winning.

"Emma, in order to help you, you have to tell us what happened." Caitlin said. Emma snuck out of her window to tell Barry and the two others about the message. She was a little frightened, but it can't be the kidnapper. He's dead, Stiles had killed him.

"It can't be the kidnapper, Cait." Emma's voice shook as she spoke. She didn't want to tell them, but she had no choice. She needed help. "Stiles killed him. I watched it happen with my own eyes. He buried the body because he thought it wasn't self defense. It was. He only wanted to help."

There was a moment of silence, nobody talked or moved from their spot. Barry was the first to speak up, "Is there anything that the kidnapper said to you guys that could be useful?"

Emma was relieved that nobody cared about the fact he did kill him. Stiles surely would be relieved as well. She began to think back to when the kidnapper came to their house. There had to be something. And just like that, it came to mind. "There was something he said. Something about there being an evil spirit inside of him. He wanted to get that spirit to come out and destroy all metahumans."

"Dark spirit? I've heard something like that. Hold on," Cisco made his way over to the computer, a twizzler hanging out of his mouth. Emma giggled a little to herself, he looked adorable in her opinion. Cisco's face had an expression she couldn't read and she began to worry. The twizzler fell out of his mouth as his jaw dropped.

Emma furrowed her eyebrows, completely concerned, "Cisco, what's wrong? What is it?"

"Nogitsune,"

"Nogitsune?" Emma thought that sounded very familiar. Didn't I hear that in a TV show or read it in a book?

"It's a dark spirit or kitsune. It feeds off of pain. Power comes from chaos, tragedy, strife, and pain."

Emma's heart dropped hearing these words come out of Cisco's mouth. She looked down, tears escaping her eyes. She couldn't believe it, she wouldn't believe it. The kidnapper had to be lying. My brother does not a dark spirit in him.

"No, no, my brother is fine. He doesn't have a dark spirit in him."

Barry said, "Emma, it would make sense. The way he has been acting. He's never acted that way."

"He does not have a dark spirit in him! Shut up, shut up, SHUT UP!" she couldn't handle it all. Every time something good happened, something bad always followed behind. A sob escaped her lips, tears streaming down her face. The blonde closed her eyes, she wanted this to be all a nightmare and that she would wake up any second and forget about it. Arms engulfed her in a hug and she sobbed into their chest, make up staining their shirt.

"We need to go find him before he does anything." Emma sniffed pulling back, she wiped away the tears on her cheeks.

"I'll go do it. It will be better hearing it from me than any of you." she didn't mean for it to come out in a mean way. They all nodded, thankfully taking no offense to what she said. "Can I actually do it tomorrow? I'm not ready to face him just yet."

"Would you like to stay with me, Em?" Caitlin questioned.

"Yes please,"

Morning came by and Stiles was beginning to wake up. He didn't remember anything after Emma left last night. When he had became himself again, he searched for alcohol and drank until he passed out. He tried reaching out to his little sister in hopes she would answer, but she never did making him cry in frustration. He currently had a huge hangover, the light coming through his window wasn't making it any better either. It hurt his eyes.

Stiles groaned upon hearing someone talk in an English accent, "How're you, love?"

"Why are you yelling?" a light chuckle was heard from across the room.

"You have some asprin on your side table. When you have taken it, come downstairs. I made breakfast for the two of us. Oh, and nice hickey's there. Wonder who gave you those," light footsteps padded across the floor, the sound fading away as Oliver made his way downstairs and into the kitchen.

Stiles began to slowly peel his eyes open having to blink a couple of times to get used to the brightness. His head pounded and he gritted his teeth at the pain. The hazel eyed boy sat up, taking in his surroundings. His room was trashed. His dresser had been pushed over, creating a huge mess, there were two holes in his wall next to his door most likely created by his fists. His gaze quickly went to his hands which were bandaged. He furrowed his eyes, he hadn't even felt any pain coming from his hands. What happened last night? Why is Oliver here? Stiles reached over grabbing the pill and swallowing it easily.

The smell of bacon hit him and his mouth watered, his stomach growling. He swung his legs over the bed, stretching then got up. He left his room, coldness surrounding him. Oliver was in his kitchen, no shirt covering his torso. No sign of Emma, sadly.

"Not to be rude or anything, but erm why are you here?"

Oliver chuckled, "You texted me last night at least a billion times then called me until I picked up."

"Oh god," Stiles' cheeks burned, well that's embarrassing.

"Don't worry, your messages were explicit but very hot and amusing."

"I'm not going to look at them. That's just embarrassing." the two laughed a little, Stiles' eyes brightening. "Did my sister come home?" when Oliver shook his head, the hazel eyed boy's heart dropped. Stiles looked down at the counter suddenly interested in it while tears were threatening to fall, but he refused to cry in front of the guy he liked. She hates me, he thought to himself.

"What happened between you guys anyway? It sounds like it's pretty bad." said Oliver as he put the last plate of food down on the island. Stiles stifled a laugh seeing the hickeys trail up his neck that he gave to him.

The hazel eyed boy cleared his throat, "We got into a fight. I erm I hit her, but like I'm not crazy, it was not me. It was like I had no control over my body."

"People make mistakes, love. They learn from them and then they move on. She'll forgive you. Just give her time."

"I've never hit her before, Oli." Stiles sighed, he's been holding in a secret that he has never told to anyone. Only him and his father know. But he thought it was time for him to talk to someone about it. "Before she was born, my dad and my mom decided to take a break. He went to the bar and came home with a beautiful blonde. A couple weeks later, she found out she was pregnant and by then, my dad and mom got back together. She kept the baby a secret until a 10 months later, she found out it was very hard to take care of a baby. She found my dad and asked if he could hold her baby and him being the nice guy he is, he held her. She ran. My dad didn't give the baby to a foster care. He instantly knew that the baby was his. A couple years later, the mother came back and took her daughter during the night while everyone was asleep. She thought she could handle taking care of her, but she couldn't. Oliver, she returned the baby but she had bruises on her bottom."

"She hit her?"

"It seems that way." the two began to eat in silence, the only sound that was heard was their forks hitting their plates. The silence didn't last for very long though, the front door had opened and slammed closed. "Emma?!" Stiles left his seat and speed walked through the hall way, his legs moving faster than his mind can comprehend.

"Stiles?" Emma came into view, Stiles instantly seeing a small cut from where his nails scratched her when he hit her. The blonde sighed in relief, her brother still seemed sane and she instantly ran to him throwing her arms around him. The coldness she saw the day before was no longer there, his eyes were full with worry and relief.

"I'm so so so sorry I hit you and called you names. I have no idea what came over me, I felt like I had no control over my own body. It was like I was trapped and couldn't take back over my body." the hazel eyed boy apologized as he hugged her tighter. The guilt stayed in the pit of his stomach, apologizing for it didn't do anything.

"I know what's happening to you. I know the reason why you are acting like this." Emma pulled back looking her brother in his eyes.

"What?" he looked down at her and just by glancing at her, you could tell she was frightened, worried.

"Remember what the kidnapper said about you?" he nodded. "He wasn't lying. It's called the Nogitsune. When you killed that man, it unlocked the door that kept the nogitsune away."

His whole world came crashing down. He began to panic, he needed to get locked up. Right away. Stiles didn't want to hurt anyone, much less kill anyone. It's all my fault, the hazel eyed boy thought. His breathing became heavy, he could barely hear his sister calling his name, or the sound of his own breath as he fell backwards into the wall behind him. Stiles slid down the wall, instinctively holding his head as he cried. Everyone is going to die because of me. He was not stupid, Stiles knew where the nogitsune draws their power from. Chaos, tragedy and strife. The spirit feeds off of the pain being caused. Stiles began to shake, he was having a seizure.

Emma screamed, "Stiles!"

"What's happening to him?" shouted Oliver. Stiles fell over, his entire body shaking, his eyes rolling back into his head.

Everything went still and silent. Stiles' body stopped shaking and his eyes were close, no longer able to see his hazel eyes. Emma and Oliver sat on either side of Stiles, hovering over the passed out body.

"St-Stiles?" Emma inched towards his face cautiously. Suddenly, his eyes flung open, gasping as he shot up as if he needed all the air he could get. The blonde flung back along with Oliver who hit the wall. "No, no, no, no," his eyes were cold and distant, Emma couldn't feel any warmth radiate from her brothers body. His head snapped towards the girl, a sickly smirk planted on his face. She gasped not having any time to shield herself before a fist flew towards her and she was knocked out instantly.

A snarl made it's way to his face, he needed more pain to feed off. He turned towards the guy who sat next to him, shaking from fear. Oliver was not doubt scared of the boy and did not make an effort to keep that hidden. But that's what the nogitsune wanted. He was fast, almost inhumanly fast. The nogitsune was up along with his knee that hit Oliver in the head. Though he could not of cared less if he created brain damage, he needed the most pain he could get.

He smirked, "Took you long enough," he fished through his pockets, looking for the small device that was the key to finding the Flash. He rolled his eyes finding that the body he took over did not have a lock on his phone which to him was an idiotic thing to do. He strolled through his contacts finding the man he needed instantly.

stiles: where are you? I need to talk to you right away!

barrythebear: I'm at Jitters, what's wrong?!

stiles: I'll tell you when I get there

barrythebear: is everything ok?

The nogitsune didn't bother to text back when Barry texted him. He grabbed the keys to the car out of the bowl next to the front door and left the two people important to Stiles lying on the floor.

***

Jitters was in sight, the nogitsune had parked a block away. He needed to cause chaos, more chaos. The pain he caused was not enough for him to take complete control over Stiles' body. He needed to be stronger. Stiles was really strong for a human, he was most definitely a fighter. Stiles was not happy with the fact he hurt Emma and Oliver and was fighting to get his body back. He was winning, but soon the nogitsune will be winning.

The nogitsune strolled into the cafe, Barry and Iris coming into view quickly. He went through the plan in his head and it was perfect although he had to make it believable. The spirit threw on a panic looking face and ran towards the couple pretending to breath heavily.

"Stiles, woah, calm down. What's wrong?" Iris questioned, honestly concerned for her boyfriends best friend.

"S-something happened to Oliver. I need your help." the couple nodded, letting the hazel eyed boy lead the way. They were worried for the boy, if he lost Oliver, they would lose Stiles. For the dark spirit, everything was going perfectly. He could feel the pocket knife in his pocket, bouncing as he ran to the destination. It was getting closer.

"Stiles, where are we going?"

"We're getting close. Just hold on," the nogitsune took a sharp left into the alley, the smirk invisible to the couple. He jogged to the green dumpster in the corner and began to dig through it. "Iris, I need you to come here and help. Barry, keep watch." Iris nodded, walking over to where the nogitsune was completely oblivious to what was about to happen. He handed her random things he could find.

"Stiles what are you looking for? Where's Oliver?" asked Iris.

The dark spirit sighed, annoyed with her. "God, you are so annoying." he took out the pocket knife, turning to the brunette who gasped dropping the stuff in her hands. He drew his arm back and stabbed the girl harshly in the abdomen, next to her stomach.

"NO!"

Next chapter is going to be big for all you Allenski shippers! But warning do not get too attached. 

I changed Emma's age. Just so that you don't have to go through the book to look for it, she is now 22 years old instead of 15. I found a celebrity that I thought would fit her character. I also found a love interest for her as well.
