Final Part of the story requested by Risk_Dash

As she lay unconscious on the bed, I couldn't help but study her closely. The similar way her eyelashes dusted her cheeks as she slept, her hair I ached to run my hands through once again. Everything about her seemed the same, but so different at the same time. The tattoo on her arm a glaring reminder that I hadn't been able to save her. That she had died on my watch, and now something had returned her topside, turning her into a viscous killing machine. A machine that I might have to kill. The thought sent a shiver up my spine, and I wasn't sure if I would be able to.

"Dean, we need to work fast. She won't be out for long." Sam said softly, knowing the turmoil I was going through. "We need to search for a way to save her, or face the possibility that we might have to..."

"I know that Sam. It's just...." I started before ending my sentence. He knew how I felt, there was no need to take out my frustration on him. 

"Dean, I wish I could be of more help, but I haven't heard of a symbol like this. It's Demonic, I know that. But as to breaking it, I can't help. Call me if you need anything else." Cas apologized before reaching over and healing my wound effortlessly. Without another word he vanished, leaving Sam and I with an unconscious Y/N. 

"Great." I muttered, just as Sam opened up his laptop. Sitting down across from him, I opened up Dad's journal, hoping for some sort of clue in his crooked handwriting.

An hour passed and Y/N had yet to stir. Sam was still hunched over his laptop, furiously typing away while I was coming towards the end of the journal. Disheartened, I was about ready to shut it when I saw something written down in the margins. The symbol seemed close to the one on her wrist. Reading what Dad had written, I was finally feeling a little bit of hope that I would be able to actually help Y/N.

"Sam, I think I might have something." I told my brother just as Y/N began stirring on the bed. "Damn it, I thought Cas said she would be out longer!" I exclaimed, rushing over to the bed. She hadn't totally woken up yet, but I knew as soon as she was conscious we were in trouble. 

"Try to figure it out!" I yelled at Sam, tossing him the journal as I rushed over towards her. Just as I reached the bed, Y/N sat straight up in bed, her eyes wild as she glanced around the room. Her eyes might not be black, but you could just feel the evilness rolling off of him. 

"Y/N, wait." I started, but before I could grab her she was off the bed, rushing towards the door. Jumping forward, I wrapped my arms around her, both of us falling to the ground. Wrestling on the ground, I was quickly losing control. Whatever that spell had done to her had made her strong, much stronger than before. Wincing as her elbow connected with my cheek, I hesitated for a moment, not wanting to hurt her, knowing that my Y/N was in there somewhere. 

"Dean, here!" Sam yelled, tossing a pair of handcuffs my way. 

"Maybe a little help!" I yelled back, reaching over and grabbing the cuffs. 

"Hell no!" She cussed, rearing back and letting another punch fly, this one connecting with my lip. 

"Ugh." I groaned. Still grappling with her, I finally got one hand in a cuff. 

"I'm going to skin you alive." She growled. "You, that man over there. I can't wait to inflict as much pain on you as possible."

"Promises." I answered. With a groan I was able to pull her up off of the floor. Sam had pushed a chair close by, and I attached the other cuff to the chair. It wasn't much, but it gave me a chance to take the rope, tying her up before she could inflict any more damage on my already sore body. 

Breathing hard, I placed my hands on my knees. "So Sam, you figured anything out?" 

"Yeah. There's a reversal spell, but it's pretty nasty, and Dad wasn't sure it would even work. He said that even if it did it might kill her all over again." He explained, turning the laptop back to him so he could look up more information. "The spell is relatively easily, and we already have all the ingredients."

"Set it up, I'll keep an eye on her." I told him, watching as she fought against her confinement, spewing profanities. 

"Dean, we're going to have to break the mark. That means inflicting pain." Sam said before he went out to the Impala. 

Sitting down across from her, I waited for Sam to come back. "You know, I actually remember you." She said, and my head snapped up, staring at her in surprise. So far all of her actions had pointed to the fact that she didn't know us. 

"You're just trying to reel me in." I answered carefully.

"No, it's true. I remember you, and Sam. Even Cas the awkward angel. I remember how much I loved you. But do you know what?" 

I knew better than to answer her, but I couldn't help myself. "What?" I asked, watching as an evil grin broke out on her face. 

"I don't care. I don't feel any of those emotions any more. To me, you are just three people that got in my way. And I can't wait to watch the light fade away from your eyes. And it will, I promise that." She purred, just as Sam came rushing back into the room, his arms full.

"I'll add the ingredients, you break the mark. With any luck it will be over in an hour." Sam said, frowning when he noticed the bleak look on my face. 

Pulling him over to the side, I leaned forward, speaking low. "She says she remembers, everything. I'm just afraid that this isn't going to work." 

"If it doesn't, you know what we have to do." He said, watching me carefully.

"I know. And I will be the one to do it. But let's hurry up and get this over with." I muttered, taking the knife from my bag and striding back over to Y/N.

"Aww, did you guys talk about me? About how hard it's going to be to kill me?" She asked, her face lightning up at the thought of blood, even if it was her own. 

Without saying another word, I leaned down, running the knife along her arm, watching as it sliced right through the mark. Blood welled up, but the deed was done. The mark was sliced in half.

Stirring a bowl, Sam came walking over to me. "It's ready. We take this paste, pack it on and around the mark. We say these words, and it should be done."

Taking the bowl from him, I began placing it on the mark. Wincing as her skin started bubbling and she started moaning in pain. Still I kept at it, even when she smacked her head against mine and I swore I was seeing stars. 

"Damn it." I mumbled, knowing my face was going to be a multitude of bruises the next morning. Pressing down against the still bleeding wound, I made sure the paste made it's way inside.

"No! You're going to kill me!" She screamed before her head slumped forward.

"Do you think we did? Kill her I mean?" I asked, knowing that was a distinct possibility. Pressing against her shoulder, she didn't move. 

Rubbing my hand along my mouth, I went to the fridge, grabbing a beer. Downing it all in one long gulp, I tossed the bottle into the trash can before continuing my pace around the room. With my eyes on her, I waited for signs of life.

My gaze kept moving from Y/N to the clock, watching as time slowly passed. An hour, then two. Sam had left, getting food that laid uneaten on the table as I waited for her fate. To know if we killed her, of if she would survive.

It was about three hours later when she finally showed signs of moving. Her entire body started shaking, as if she was experiencing a horrendous seizure. "Y/N?" I asked, kneeling down next to her. Throwing her head back, she kept shaking, her eyes rolling back in her head. 

"Damn it Sam, I think she's dying!" I exclaimed, tears in my eyes as the threat of losing her was right in front of me. 

"Dean, it might be for the best." He answered, placing a comforting hand on my shoulder. "I know it will be hard, but we already lost her once."

"Dean?" I heard a small voice whisper as my attention was focused on my brother. My head turned so fast I heard the pop of my neck. 

Staring at me was Y/N, her eyes wide with shock. "Y/N!" I exclaimed, ignoring Sam's warning as I reached forward, untying her from the chair. Slumping forward in my arms, she started shaking once again. Pulling back, I noticed she was sobbing. "Shh, it's okay. It's all over now." I assured her, rubbing her back.

"It was horrible. I wasn't myself. That Demon spelled me. In Hell he made me..." She started, tears running down her face.

"The mark is gone. You're back to normal now." I assured her, but it still hurt seeing the pain and guilt in her eyes.

"But all the people..." She whispered, and I placed my hands on her cheeks, making her look at me.

"That wasn't your fault. Sure it was your hands, but all the blame goes on that Demon. I know it will be hard to get past, but I will be here for you. It's been so hard without you." I comforted her, loving the feel of having her back in my arms.

"Thank you for not giving up on me." She whispered, before tilting her head up. With a soft smile, I leaned down, pressing my lips against hers.

"Of course I wouldn't give up on you. Love you too much for that." I assured her.

That was the last part. Hope you liked it!!
