Stiles' POV

Later that night I was sitting in front of my computer face timing Scott about what I'd found out from my dad when my screen froze up and I heard my bedroom window slide open. I stood up turning around. Derek was standing in front of my window staring at me. Watching me actually.

"Derek, what are you--" I start.

"Shut up Stiles."

I clamped my mouth shut and watched him as he came towards me slowly. He stopped in front of me, his blue eyes staring down at me. I held his gaze for as long as I could before looking away sheepishly. Derek gently lifted my chin, stared deep into my eyes and kissed me. My eyes widened in shock as my mind tried to wrap itself around what was happening. Derek was kissing me. Derek fucking Hale was kissing me! But it was a slow gentle kiss filled with passion. And then I was kissing him back. A warm fuzzy feeling hummed throughout my body as he placed his hands on my waist. Everything felt right in this moment. I wasn't sure who pulled away first, me or him but I didn't care. Derek had just kissed me. Derek fucking Hale. And I'd kissed back.

Derek smiled, raking his fingers through his hair. "God, I've wanted to do that for a while now."

I looked at him surprised. "Really?"

Derek nodded. "Yeah. Earlier today I was going to say that Dean guy was coming into my territory."

I raised an eyebrow and said, "Territory? You care about me?"

"Hell yeah. How can I not?" Derek says. "I love you and I'd do anything for you." I blushed, biting my lip. "Which reminds me..."

Derek pulled me over to the window and I looked down into the driveway. There it was. My blue jeep, clean and shiny as is nothing had ever been wrong with it. I glanced at Derek, my eyes wide with happiness, a goofy smile on my face.

"I fixed your Jeep. Figured it would make you happy." Derek says smiling back at me.

I threw my arms around him, burying my face in the crook of his neck. "Thank you Der." I say. Der was a nickname I had made for him a while ago when I realized I had a small crush on him. Derek wrapped his arms around me breathing deeply.

"Anything for you, Stiles."

-------------------------------------

The next day at the Archery range during training, my mind was elsewhere. Specifically on a guy named Derek Hale. I couldn't stop thinking about Derek's lips on mine, his hands on my waist, the three words that mad my heart flutter.

'I love you.'

Derek Hale loved me and apparently had for a while. I just couldn't believe it...but it was real. And it was happening. If I was Derek's territory could that mean I was his mate too? I didn't know for sure but I was pretty sure Derek would know. I was also pretty sure I loved Derek back. I was so caught up in my thoughts about Derek, that Dean managed to flip me over his shoulder. I landed on my back, the air leaving my lungs in a 'whoosh!' I blinked a couple times, before sitting up. Dean was frowning at me.

"Stiles are you okay? It's like you're here but you're not."

I nodded, climbing to my feet. "I'm fine. Just thinking."

Chris and Sam strode over to us. "About what?" Chris asked.

I contemplated on telling them but thought better of it. "Nothing."

Chris sighed, pinching the bridge of his nose. "Stiles, you need to focus and concentrate on your training. One mistake out there could cost you your life."

"You don't think I know that?" I say exasperated. "I'm trying here! Okay? I'm trying."

"Well try harder!" Chris yelled. "Or don't try at all, just do it! Stop acting stupid and do what I taught you to do!"

"What the hell do you think I'm doing?!" I yelled back, flinging my arms out. "I'm trying alright?! I'm giving it my all! I'm tired of being seen as a liability!"

"Maybe it's because you are!" Chris shouted.

That totally stung, but I tried not to show it but judging by the look on Dean and Sam's face, I knew I failed miserably. They watched but I paid no attention to them. I stared at Chris and said, "I hate you."

I turned to leave and Dean grabbed my arm. "I'll walk you to your jeep."

I wrenched my arm away from him. "No thanks. I'm perfectly capable of walking to my jeep without getting myself killed."

I stormed across the clearing, down the path to the parking lot and hopped in my jeep, driving off down the road. I didn't feel like going home so I decided to go to Derek's loft. I hadn't seen him all day. I needed to see him. I needed to touch him. I needed him...no I craved him.

Pulling up to Derek's loft, I saw his car parked in his usual space. I parked beside his car and got out. The minute I did I knew something was wrong. I grabbed the gun that Chris had given me and took the elevator up to Derek's loft. I stepped off the elevator and walked inside. 

What I saw was not a pleasant sight.

Derek was bloody and beaten and he was lying on the floor writhing in pain;Braeden was bleeding from a cut running along her hairline and she was unconscious, her shotgun lying at the feet of a man who had to be six feet seven, brown eyes ad dark hair. And who the hell was I kidding? He was four times my size. Muscular and cocky...I could see why Derek couldn't possibly beat him. The man tensed and turned around to face me. He smiled creepily and said,

"Now you must be Stiles."

I didn't hesitate for a second. I brought the gun up, took aim and fired. For once the kickback didn't send me stumbling. I watched as the bullet cut through the air...and bounced off of him. What the...Did I not aim correctly or something?No. That wasn't the case.

The man gave me a taunting smile and slowly walked towards me. I squeezed off four more shots, the bullets harmlessly bouncing off his body before he reached me, knocking the gun from my hand and grabbing me by my throat, slamming me against the wall. I wasn't scared--no I was terrified.

"What are you?" I ask, trying to keep my voice from trembling.

The man's eyes turned black and I gasped. "I'm a demon. I go by the name of Grego Arkright." He looked me up and down. "But you my young prince my call me master or your Highness."

"P-Prince?" I stutter. 

"Oh yes, oh yes. When I'm done with you, you'll be begging for more." Gregor said, ignoring my question. My eyes widened and Derek growled deep in his throat angrily. Gregor smirked. "No need to be afraid. I'll be gentle."

I shuddered in disgust. The only person I wanted that way was Derek. Not some fucking stranger. Without thinking, I brought my knee up into his crotch. Even if I couldn't kill the guy, the asshole wasn't immune to pain. Gregor groaned, shoving me to the ground and cradling his private parts. I scrambled for Braeden's shotgun as Gregor recovered enough to grab my ankle and drag me back towards him. I aimed a kick at his face and my shoe connected with his nose. Blood spurted and surprised he almost let go of me. Almost. Instead he roared in anger, picked me up with ease and flung me across the room. I crashed into a far wall and crumpled to the ground. A silent scream escaped my lips as Gregor's hulking figure bore down on me. I rolled out of the way just in time and scrambled to my feet only to fall to one knee as pain filled my left ankle.

Shit, I cursed silently to myself. 

I had no choice but to get to my feet and limp as fast as I could for Braeden's shotgun. Something collided with the back of my head and I fell onto my stomach inches away from the shotgun. I grabbed it, rolled onto my back, racked a shell into the chamber and pulled the trigger. The shotgun blast was deafening and I thought I lost my hearing for a little bit. Gregor had stopped his advance and where his head used to be was mangled flesh and blood. A lot of blood. Gregor dropped to his knees before collapsing forward, blood pooling on the floor. I let out a breath I hadn't realized I was holding as the reality of what I'd just done sunk in.

Demon or not, I'd just killed a man.

-----------------------

I don't know how long I sat there cradling the shotgun and staring at Gregor's dead body. It must've been a while though because Scott, Lydia, Dean and the others were rushing into the loft. I barely noticed when Dean pried the shotgun from my numb fingers. Someone covered the body with a white sheet but I continued to stare at it.

"How long has he been like this?" Parrish asked.

Derek who had been tending to Braeden said, "Since he pulled the trigger."

Someone stepped in front of me blocking the view of the body. I looked up and saw that it was Dean. Since I couldn't see the body, I stared at my hands, which were shaking. My whole body was shaking.

"Stiles what's wrong?"

I looked up at him my vision becoming hazy and blurry. "I killed him."

And the I passed out.
