Stiles POV
The time had come, I complete this, and then the ceremony comes and then the injections stop.

Not only will the injections stop but I won't be a "greenie" anymore.
The mission was to kill off a group of failed experiments that were trapped inside a warehouse.

"Perfect." Stiles thought. "They're all in a closed area, this will be easy."
He was so excited that the injections may finally stop. 3 times a day, everyday. Stiles touched the sore spot on his neck where they inject him, and flinched a little at the pain.

He didn't know what they inject him with, but he falls unconscious and wakes up with his memories jacked up. The worst part is he doesn't know what he's forgetting.

As he pulled up at the warehouse, he was still deep in thought. Quickly snapping out of it he grabbed his gun and various knives and strapped them to his belt. "Here goes nothing

(One hour later)

One left. He had one little failure left, and then he would complete the mission. This one would be easiest considering the others fought and this one ran.

Turing around a corner, he heard heavy breathing, followed by a quiet. "Do you want to die? I thought not so be quiet."

"Huh guess I have two left" Stiles thought.

He raised his gun and kicked down the door he heard the voices in. He was right there were two of them but the other person didn't look like an experiment. He looked a little familiar too.

"St-Stiles?" I guess the guy thought he looked familiar too.

"You're the one killing these innocent people? What the hell are you doing?"

I tightened the grip on my gun.

"Who the hell are you and how in the hell do you know my name?" I practically yelled at him.

" Come on, don't be like that Stiles, you know exactly who I am!" Derek yelled.

"I swear I have no idea who you are! That's why I asked who in the hell you were!" I replied slowly getting angry at the beautiful man in front of me.

Apparently he was getting angry too.
"Look I don't know why the hell you left me. We promised each other we wouldn't do that. But trying to forget me is a new low Mieczyslaw!" How in the holly fire in hell did he know my real name.

"How do you know my real name? Obviously you know me and it's only fair since I don't think I'll be completing this mission any time soon."

"Derek, Derek Hale. Your boyfriend."

The name sounded familiar but it didn't strike any memories.

"I think I would know if I had a boyfriend." Especially one so beautiful.

"Nice try though, A for effort."

I aimed my gun at the teen's stomach and fired.Derek looked at me with shock evident on his face.

" Get out of my way Derek or you'll end up just like the others, dead."

"You won't shoot me."

I laughed  " oh I won't now?"

"No, you won't."

I was getting mad now.

"TELL ME! TELL ME WHY I SHOULDN'T SHOOT YOU DEAD RIGHT NOW!"

"Because, I love you with all my heart."

The memories came rushing back, like the dam of my mind just crumbled to the ground.

I dropped the gun and fell to my knees,
I remember.
Flashback:

We were sitting on top of the lookout. Enjoying each other's presence.

Derek was still healing from one the fight with the rouge pack.

Scott and the others went home afterwards,but Derek and I went to our spot.

I leaned over and kissed him.
"I love you."
"How much?" He replied. Looking over at me.
I smiled at him.
"With all my heart."

Another flashback:

I burst through the doors of Derek's loft to find him on the ground not moving.

"Derek!" I yelled as I ran over to him.

"No no no no no no no. Come on big guy, you're okay." The slash marks across his chest were really deep.

I felt for a pulse. It was faint and felt like it was slowing, but it was there.

"Please, I can't do this alone." I whispered and kissed him.

"SCOTT!" I screamed hoping he was nearby.

"SCOTT! Derek needs help! I-I can-I can't help him! SCO-!" My voice cracked at the end.

I was crying so hard everything was blurry with tears.

I kissed Derek again, and readjusted his body to where he was in my lap.

I held him tight.

Not letting go.

As I rocked his body back and forth i kept praying he would wake up.

"I-I...I love you" Derek whispered.

I stopped rocking us and looked down. Der still wasn't moving.

I leaned down and kissed him.

I felt him kiss back slightly. I knew I didn't imagine that!

A grin blew up the edges of my mouth.

"How much, big guy?"

Derek open his eyes a little.

"With all my heart"

End flashbacks

As all of my memories come back the new ones I made as an assassin made their way into my mind.

I shakily stand up. "Derek, I- I'm so sorry!" I burst into tears.

I wanted nothing more than to cuddle up next to Derek, but I could barely look at him.

"Stiles...... it's okay, you're okay. You weren't in your right mind."

I looked up at him but all of the faces of the people I've killed were the only thing I could see.

"I-I-I killed peop-" my voice cracked as I try to catch my breath.

Derek pulled me into a hug and kissed me. I tried to pull away but he held on tight.

He finally pulled away.

"Derek.... I-I'm a murderer. I deserve to die!"

He grabbed my shoulders and forced me to look at him.

"Stiles! Don't you ever say that again!"

"But I am a-" Derek interrupted me.

"Do you consider me a murderer?"

I look up at him shock and confusion painted across my face.

"No! You aren't a Murderer Der! You're just a sourwolf." I joke trying to lighten the depressing mood.

"Look into my eyes."
His forest green eyes changed to their electric blue.

"You know how I got my blue eyes Stiles..... I've killed an innocent. Wouldn't that make me a murderer?"

"But that's differen-" I try but Derek interrupted me.

"No it's not, we'll get through this Stiles, we always do." Derek took my hand in his.

"Now how about we go home?"

"But the people that kidnapped me..... they'll just take me again." I shuddered remembering all that they did to me.

"And we'll deal with it. Together."

"Okay" I said while nodding my head.

"Lets go, but first what about him?" I point to the experiment laying dead on the floor from my gunshot wound.

"We'll take him to Deaton's." Derek sighed.

I nodded and pursed my lips.

"Okay lets go."
