The End

Chapter 3

...

Derek drove back to the subway in a rush and almost broke the doors down when he was back. Erica lifted her head up and shared a confused look with the rest of the pack. They had never seen their Alpha this angry at something and they didn't know if they should say anything or just let him deal with it himself.

He took off his jacket with force and swung it away. He grabbed the nearest chair and smashed it into a wall, making it explode into thousand smithereens and his betas jumped.

"Erica, go online and find everything you can about demons! Isaac and Boyd, go to a shop and get me two more laptops and every book on demons and possessing humans and everything in that genre" Derek barked orders, his eyes red and claws out. He looked over at his betas and when they didn't move, he growled like an Alpha and they scrambled away, almost running over each other just to get away from Derek.

When he was alone, he picked up his jacket and hung it up on a wire that went from one side of the room to the other and sat down on the only chair left. He held his head in his hands and took deep breaths to call down. He didn't know what to do. Even if the demon had said that it doesn't want to hurt Stiles, Derek knew not to trust the words. He just hoped that they will find something useful.

"Derek?" Erica's soft voice brought him back to the now and he turned around to look at her.

"Yes, Erica" He replied.

"Why do we need to find out about demons? Is that like a new threat now or something? "She asked quietly not wanting to anger her alpha even more.

"No. I don't know actually. It's just... Stiles is possessed by a demon and we need to find a way how to get him out before something happens. So you keep looking and call me when they come back, I need to do something" Derek said and after receiving a nod from the blond, left the cave and drove to Scott's house.

He called the young wolf and waited for him outside. When he saw Scott come out of his house, Derek got out the car and walked towards him.

"We have a problem" Derek said holding his hands in his pockets.

"What kind of problem?" Scott asked.

"It's Stiles. He's ... he's a demon"

"What? What are you talking about? He's not a demon. I know you don't like him much but that is too far, Derek" Scott said and his voice kept changing range as he spoke.

"No, you stupid. He's possessed by a demon. I saw him tonight, it's not pretty" Derek said and rolled his eyes. Leave it to Scott to always say something not worth saying. How he is friends with anyone is a surprise to Derek. He could understand Stiles, that kid was funny and annoying, not that Derek will ever admit it out loud, but Scott was just ... irritating.

"Oh. So what does that mean?" Scott asked, scratching his head.

"What do you think it means? Use that head of yours for something. Trust me, it will tell you the same, I already heard." Derek said and scoffed.

Scott looked like he hadn't understood a word Derek said so instead, the alpha told him to get everyone ready and meet him tomorrow at his lair. They were going to need all the help they could get if they wanted to stop this thing without hurting Stiles.

Erica was clicking through the pages in front of her on her laptop, trying to find something useful but all the pages didn't really give her the answers she was supposed to find. She sighed and opened another page, blowing her hair out of her face. She read the words until a line caught her eye.

'...usually sensitive people get possessed'

Erica thought about it and realized that it did answer why Stiles of all people in Beacon Hills attracted the attention of the demon. She texted Derek saying that she found something and kept reading until she heard the rest of the pack mates had come back.

Isaac put the laptops on the floor and flopped down next to her in the seat, looking at what she had found. Boyd took a seat opposite them and started reading through the books.

"So do you know why he's making us do this?" Isaac asked.

"Stiles got possessed" Erica answered not taking her eyes away from the screen.

Isaac sat up straight in his seat and looked at her. "Wait, what? How do you know?" He asked.

"Derek told me right after you two left. " She replied, and then lifted her head looking over the stuff they brought. "Did you get everything? Because you know how he will be if you missed anything. Start reading, I would like to get some sleep tonight"

"How would that even happen?" Isaac asked, picking up one of the books and going through the pages.

"That's what we need to find out, I think" Boyd spoke, "And I agree with Erica, let's find something so we don't have to do this all night"

The betas researched in comfortable silence, the only sounds heard were Erica's tapping on the keyboard and the pages of the books shuffling when being turned.

Erica kept thinking about how this had happened and what it meant. She couldn't find anything on how to get the demon out except an exorcism and she knew that wasn't what they were going to do. She thought about how it felt to be possessed, she would have to ask Stiles when all this is over. She thought it would be similar to how she used to get her attacks. You lose control of your body but deep down you are still in there somewhere. She felt sad just thinking about it.

Isaac on the other was scanning through the pages and couldn't understand a word that was written there. The book he was holding was all about different types of demons from all over the world and it wasn't helping him find what he was looking for. He doubted this was just any type of demon but he didn't know much so it didn't help him knowing what was useful and what wasn't.

Boyd was the only one who was doing both, on the laptop that he found a socket to plug it in and in the books. Every time he found something in the pages, he went online to see if there was anything more on the subject. So far he found many interesting articles but none of them explained how to get rid of the demon without killing the human in the process. He sighed and shook his head, they have been looking for hours and Derek still hadn't come back. If he was worried about his alpha, he didn't show it and just sat in silence trying to find anything that would be of any help.

After leaving Scott's house, Derek drove to check in on Stiles, or rather the thing that has taken residency in Stiles' body. He still didn't understand why he was so adamant on saving Stiles but his brain kept telling him that Stiles' was pack and he was supposed to take care of his pack even if they sometimes drove him so mad that he wanted to kill them himself.

The house was dark when he arrived and hearing no heartbeats, Derek let himself in through Stiles' window and went on his computer to try and find something. He had received a text from Erica but he had to do something himself too, as the demon had told him, and if he went back now, he would probably find all three of them on laptops and he didn't want to go through the books right now, so he turned the computer on and waited for it to load.

When it was done, Derek typed 'demons' into the search engine and watched all the results pop up in front of him. The first link was nothing but an explanation of the types of demons and he sighed knowing that it will take him forever just to fin d anything useful and he thought that if Stiles was here he would probably find all they needed in five minutes flat. Derek made a note to thank Stiles for all he always does for the pack and to not take him for granted so much.

He was on his second page of links when he heard a car pull up and he switched of the monitor and got off his seat, opening the bedroom door slightly to see if Stiles was back or not. Hearing the light footsteps that re recognised as Stiles' , he hid behind the door only realising then that all of Stile's previous names of him being a creeper might actually be true, but at that precise moment, Derek couldn't really care.

"No, I don't think that" Stiles said and Derek furrowed his brows. "I just never saw it like that and there is nothing you can say that will make me think otherwise"

Derek came out from the shadows and put his hand on Stiles' shoulder making the demon jump.

"Yes, you are right, he's a creeper" Stiles said, "Derek, nice to see you again, have you found a way to get rid of me?"

"Who are you talking to?" Derek asked.

"The one who is in my head." He answered, and then shook his head, "Okay fine, it's his head and I'm only borrowing it but point remains."

"..."

"So, what are you doing here? Come back for some more kissing?" The demon asked, batting his eye lashes and pouting sarcastically.

Derek growled and the demon laughed.

"Oh relax your glowing eyes, I'm joking" The demon said and flopped down on the bed.

"Why are you doing this?" Derek asked standing by the window.

"Why am I doing what exactly? Because I am doing many things right now, so you'll have to be more specific." Demon answered

"Why Stiles?"

"Oh, hmm not sure really. Just sort of happened. Why, are you feeling left out? Do you want me to possess your body rather?" He asked, looking at the wolf.

Derek mulled it over in his mind, maybe this was something they could do. He could takes Stiles' place and Stiles would find a way how to get rid of the demon in record time.

"Yes." Derek answered, taking a step closer to the bed.

"And why would I do that when I have a human right here? You're a wolf and a hot one at that, but why should I leave this human?"

"Because he's human. He's not strong enough" Derek said.

The demon looked like he was thinking and then answered. "Yeah, you see, Stiles here thinks that you are wrong and you just offended both of us, so no, I won't do that. But you have a good day" He replied, getting up from the bed and standing close to Derek, "So if you don't mind, we would rather go to sleep. Big day tomorrow"

"What's tomorrow?" Derek asked alarmed

"Like I said, bye bye, you know where the window is" Demon said and left the room to have a show.

Derek looked at the door and growled shaking his head. Stiles would have never spoken to him that way, but it was kind of good that someone called him out on his behaviour. It's been a long time since anyone had done that. Climbing out the window, he got in his car and drove back to his cave.

Erica was on the laptop, barely awake and holding he head up with one arm, Isaac was next to her with a book in his lap but his eyes were also almost shut and Boyd had given up already and was snoring in his corner.

Derek looked over his betas and sighed.

"Go to sleep. We'll compare notes in the morning. Scott and the rest of them are coming so maybe we can find something useful" Derek said and the two wolfs nodded and moved to their beds. Derek noticed how Isaac and Erica had been spending a lot of time together and even their beds were getting closer and close by the day.

He took Erica's laptop and sat down, trying to continue his search from earlier in Stiles' room.

xXx

Why do you do that? You know it won't end well. You shouldn't annoy him so much.

"Why do you not do it all the time? Can't you see how fun it is?" The demon asked Stiles when they were lying in bed.

It's not fun. You only think it's fun because he can't do anything to you. If he could, you would be dead with your throat ripped out, trust me.

"I don't think so. There is something about him that makes me think otherwise."

That's because you're crazy.

"Did you see the way he wanted to switch places with you?" He asked, a smirk forming on his lips.

Only because he knew that I will do all the research and get rid of you. Not because he cares. And because he thinks I'm weak. Stupid sour-wolf thinks I can't do anything. We'll I'll show him.

The demon laughed then, realising that he wasn't wrong at all when he that Stiles liked Derek, he only needed alight push in the right direction. "Don't worry, Stiles, I'll help you" He said.

Also wanted to mention that I take requests on my tumblr. I have a few to do but I will do most of them in the morning and you are free to leave me more. My tumblr, in case you forgot is queenerica-eq, go there and leave me messages. :)
