Crash and burn

So this how Stiles gets repaid for being part of the supernatural realm he gets another curve ball thrown in his direction and this one really messes it all up as he has to kill someone. And not just anyone this person is Peter. It was never meant to happen this way, yes I was a werewolf and he decided to repeatedly get involved but he was not meant to get dragged into the world I am now part of.

Apparently due to him bringing me back he has to restore the balance and someone has to die, which has to be the one who killed me. It was like a double edged sword I get to live and Peter finally dies but Stiles has to be the one to do it. Derek said that when you kill someone it takes away a part of your soul. And for that it was going to be the hardest thing I have ever asked Stiles do for me.

"You can't do this Stiles, I can't expect you to do this."

"I don't have a choice Scott; he will continue to harm you as long as he lives."

"But we have to be smart about this Stiles."

"Why he still thinks I am human as you found out just a few hours ago and Derek hasn't told him."

"But somehow he manages to know everything about everyone in this town."

"He doesn't know and he can't stop me Scott."

Obviously and no offence to Stiles but it had gone to his head and he believes he is unstoppable and that will be his downfall as the minute you don't doubt yourself then bad things happen. I was hoping that this was just him putting up a brave front as he should be scared. I was nervous for him and he could see but he could probably feel it as well.

"You should be scared Stiles."

"I am Scott but I know how to do this and all we need is to know where Peter is and then we can take him down."

"Only you can Stiles as I can't kill anyone, even though it is Peter it isn't the right thing to do."

Stiles' point of view:

How could he think that this wasn't the right thing to do? He had said all along that Peter would get his come upance and now he finally had he wasn't going along with it. Honestly I don't believe that I have the power in me but if I didn't have any confidence in myself then no one will. I was new to this and everything and it would take all the power in me to do this.

I said I knew how to do this but if I was being completely honest I had no idea what I was going to do to Peter. Scott didn't want me to do this but he is my priority and if it kept him safe then it was the right thing to do. Scott left and I was left to talk to Deaton.

"I don't know if I can do this."

"You can Stiles as all you need to do is believe."

"How do I do it then?"

"Because of what you are all you need to do is think about what you want to happen to him."

"What do you mean by that?"

"When you do whatever to him all you need to do is picture in your head what you want to happen and say it out loud and it should happen."

"So you're saying that all along it is my mind that will get me through this."

"In a way yes Stiles but you need to do it soon as if not he will realise that Scott isn't dead and target him again. And one thing don't take Scott with you as all he will do is try to stop you."

"I know but thank you."

I left the vets and made my way home. Peter was going to be harder to kill than we thought as he had died once and come back from the dead and at the end of the day what is to stop him from doing it again? This man wasn't indestructible and somehow I had to be the one to do this.

When I got home I did a quick locater spell to find out where Peter was as I was going to have to find him. Weirdly the spell said he was still in Beacon hills and this was probably his apartment, I was wishing that he wasn't lying when he said he lived in an underground network of caves but obviously he did live in an apartment.

I really didn't want to do this and needed some protection and the only other person who I could ask was Derek. As Allison would just shoot him, Lydia was well helpless, I didn't trust the twins and I didn't really trust Isaac. And I know me and Derek don't get on at the best of times but at the end of the day he would do anything for Scott and protecting me always comes up.

"What do you want Stiles, it's 10pm?"

"I need your help."

"With what exactly?"

"Well you know I have to destroy Peter, I can't take Scott as he will stop me."

"So that leaves me?"

"Yeah it does."

"Why for once in your life can you not do something on your own?"

"Do you want Peter to kill me?"

"No as if you do die then Scott will never let me live it down. So what do we need to do?"

"Meet me at mine in an hour and then we can get started."

At least I know with Derek's help in may go more smoothly than I first expected but at the end of the day either Derek or I will get hurt. Peter does still think I am human so all I need to do is make sure it stays that way until I do what I need to do. I was actually trying to think what I wanted to do but honestly I am not the diabolical type.

Derek was at mine in the hour and he didn't look happy.

"It is 11pm Stiles so you better have a plan."

"Not exactly."

"Not exactly are you kidding me?"

"Look I know where he is so all we need to do is get there and you need to distract him while I work out what to do."

"Great so you want me to get hurt in order for you to be safe?"

"You will be fine as everything will happen to Peter and I can protect you as much as I can."

"You are going to protect me then I am definitely screwed."

I knew he would have little faith in me but going as far as screwed is a bit much but I knew I could protect him. We made our way to Peter's apartment with a very awkward and silent car journey, but none the less we made it. But when we got there it was another story.

I went to open my door and Derek put his arm across me to hold the door. He was scared and it was obvious but he had no need to be.

"Are you sure you want to do this Stiles?"

"I don't really have a choice and you know that Derek."

"There has to be another way to atop him."

"But what is to stop him from killing everyone else first, including you and Scott?"

"You're right."

"Of course I'm right when am I ever wrong?"

"I wouldn't go that far, Stiles now what do we do?"

"Go up and kill him."

We made our way out of the car and up many flights of stairs as taking the lift would show and tell him that we were here. We arrived up at the apartment and Peter was sitting there on his sofa with his arms folded.

"Well well well, what can I do for you?"

"You must know what we want."

"Well considering that I took care of Scott I can only assume that this is revenge."

"Well yes."

"And Stiles how are you going to do this as you are only human and sometimes I swear you struggle with that."

"I have more talents than you give me credit for Peter, but no Derek is here to fight you."

"Derek you really think you can beat me as the last time we fought you only won due to a fire bomb and even after that it was Scott who kicked me down."

Both of them extracted their claws and their eyes went to their wolf colours both of them luminescent blue. They walked round circling each other and growling. They charged at one another pinning each other to the ground first with Derek on top and then Peter flipping him over. Derek kicked Peter off him throwing him into the wall.

The dust fell off the wall and Peter fell into the pile of dust while Derek was picking himself up off the floor. I probably shouldn't have been paying this much attention to the fighting as the longer I put this off ten the harder it would become.

Derek and peter continues to fight on an off for twenty minutes, and even though it was pretty one sided to Peter it was still quite entertaining to watch.

"Stiles are you actually going to help?"

"What can he do?"

"Quite a lot if he actually gets around to doing it."

I was trying to focus all of my anger on Peter just hoping that my thoughts would pull this off. Whilst trying to think I could see that nothing was happening but then I remember what Deaton said all you need to do is say it out loud.

"What are you going to do me Stiles?"

"I want your blood to boil."

I could see it working as Peter was starting to sweat quite dramatically, but it wasn't enough to kill him yet. I was still trying to work this whole thing out.

"I want your organs to fail and twist in your body."

"He gtabbed his stomach and fell to the writhing in pain.

"What are you doing to me?"

"It's magic I'm killing you from the inside out Peter!"

"But you're only human."

"I was but you can thank Scott for that."

"How?"

"Him being who he is brought my genes into play."

"You're an arch mage aren't you?"

"And you're a dead man."

"You won't kill me; you don't have it in you."

"I want your heart to stop beating and for you to take your last breath by suffocating on the air around you."

His throat seemed to literally close up in front of my eyes and he fell to the floor me and Derek stood there watching his chest rise and fall until it stopped and we both knew he was dead.

"He won't come back will he Derek?"

"Hopefully not this time."

"Well at least for now we can say that he is no longer the biggest threat in Beacon hills."

Thank god at least now Peter was well and truly dead.
