So I wrote this in one day so yeaaahhh sorry if this totally sucks.
Crowley had turned you half demon so that he could have a hunter to deal with his problems and those problems were demons.He would give you a list of which demons to kill but the adrenaline pumping in your veins couldn’t care about who was on the list.You couldn’t control your craving to kill.Demons started to complain to Crowley about you. He had told you to follow the list,but you ignored him and kept killing any demon who crossed your path.That was until Crowley was fed up with your actions that he threatened to tell the Winchesters where you where.
The Winchesters,gosh you hadn’t seen them since your last encounter with them and that was 3 months ago.
You didn’t want Crowley to tell the Winchesters where you where located and how to cure you ,but also you didn’t want to stop killing demons.So you left the king of hell and continued on your own.Crowley was unpleased of your actions and made every demon go after you.After days of leaving from the king of hell and his “minions” you were tired.You knew you couldn’t keep moving from place to place just so that demons wouldn’t find you,deciding it was best for you to seek help from a witch to keep you hiding from demons.
Before you could meet up with the witch you had to make a potion to locate were she was.Gathering all your ingredients for the potion,you suddenly hear a flutter of wings .“Castiel what brings you here?” You turn around and face the angel.He didn’t say anything instead he jumped on you and started to punch you in the face.He kept punching you and yell at you" You broke Dean! He doesn’t sleep,he doesn’t eat,hell he doesn’t even hunt anymore!Just because you were stupid and listened to Crowley.How could you just leave Dean, leave us just like that! After all I’ve done so you wouldn’t end up like this! I had faith in you and you let us all down!“ You tried to look up at him but the punches made your eyes and face all swollen and bloody,that you could barely open them. You coughed the blood out and chuckled.“And here I thought we were going to have a nice and peaceful chat as best friends like before.” He didn’t respond he just punch you one more time before he pulled you up from your shirt and slammed you against the wall.“You have no idea what you did to him,to us.He hasn’t stop looking for you,for a cure to fix you.I don’t see why he even tries to fix you,you are not worth saving, You destroyed a man who would give his life for you!” You looked Cas straight in his eyes and told him “ Dean left out everything that happened that night didn’t he ” Cas tilted his head in confusion making you laugh “I take that as a yes huh?“He looked angry at you and raised his hand to grab your shoulder.As instinct you reached for your angel blade before you could even pull it out you and Cas where snapped to the library and the bunker. You looked at Cas annoyed ” Take me back Castiel!“ He just wrapped his arms around you and held you tight.You tried to get free but his grip got tighter making you scream in pain.“Cas let me go!” But he didn’t let go he simply hold you tight.
Deans POV*************************************************************************************
I heard screaming coming from the library knowing Sam had gone out for a hunt I knew someone had snucked in.Grabbing my gun I headed to the noise,when I reached the corner of the room I stood frozen.There was Cas with y/n wrapped around his arms.I hadn’t seen y/n in 3 months and here she was,her beautiful y/e/c eyes were now bloody and swollen.Her beautiful lips were now cut and full with blood,my stomach churn at the sight of her.Who did that to her and why! I wanted to kill whoever was responsible for making her be in pain.I looked at Cas and asked “ What in the hell happened to her Cas?” Cas looked uncomfortable and shifted his feet with y/n in his arms.y/n coughed and smiled “more like what in heaven,are you going to tell him or should I tell him Clarence?” Was it an angel that did that to her,before I could ask Cas spoke up.“Don’t you dare talk to Dean you abomination after what you did to him and to all of us!” My eyes widened, Cas did that to her.How could he do that,he knew her for heavens sake,seeing her in pain made me angry I wanted to punch Cas for making her suffer for calling her an abomination.But I didn’t,I took a deep breath.“Do you mind telling me what in the world were you thinking Cas! Why would you hurt her.” Cas face became angry,he took blood from y/n face and drew a weird sign in her arm,then he let y/n go. y/n snapped her fingers to leave but nothing happened, she tried walking but she didn’t move it was as if she was frozen in place. She glared at Cas and yelled at him “ What did you do! Haven’t you done enough! Also Cassie ouch! me an abomination? …What I did to him it’s more like what he did to me!” I flinch when she said that.Cas looked at her and said “I drew a sign that’s made to keep you in place,so no snapping out of here or walking away.” y/n let out a groan and stayed standing up crossing her arms in her chest. I ask Cas again “ Cas why did you hit her!” He looked again at her and yelled “ Because Dean she left us! You weren’t the only one who loved her,me and Sam needed her too,but she left without saying anything.She broke you,you haven’t been the same since she left.It’s her fault your hurt! It’s her fault you don’t save people from monsters! She lost all the trust we had that’s why I hurt her because she hurt us after all we’ve done for her!” That was the last straw Cas didn’t know why she left,after all it was my fault,I was the one who drove her away it was my fault she was like this. I screamed at the angel “Don’t you say that about her Cas! She didn’t do nothing wrong, it was me.It’s my fault she’s like this, I drove her away.She didnt brake me the way i broke her.I hurt her enough to make a deal with Crowley! So don’t you dare blame this on her!“Cas looked down at the floor ashamed.y/n laughed “Bravo Dean you finally grew a pair and told the truth!” I looked at her and saw that she was amused by what I said she cleared her throat and said “Cut the chick flick moments its disgusting,now Cassie can you undo this crap you did to me and let me leave?” Castiel looked at me asking for permission I nodded and he snapped his fingers and the sign was gone.She was about to leave when Crowley showed up “Hello boys and my my my what a surprise, my favorite little soldier where have you been I’ve been looking all over for you darling? ****************************************************************************************************
After all those days getting away from the king of hell he finally found you.Walking backwards you hit the wall.You heard Dean ask Crowley “What are you doing here?” Crowley looked at Dean,while Crowley was distracted you decided to snap your fingers and leave before they locked you up in the dungeon.
“Bullocks,you let her escape! You morons you have no idea what you have done,I could’ve helped you get her old self back!But now she’s gone and now to find her again.“Crowley hissed at them. Dean stepped forward and told Crowley ” Do you mean there’s a cure for her? Why didn’t you tell us this before! How do we know you’re telling the truth?“ Crowley smiled "There’s a cure for her "condition”,do you think I was going to let you fix the best soldier I had but now she’s gotten out of hand,she’s killing all of my demons and I can’t have that being the king of hell and all but now that she’s gone thanks to you two inbeciles she’s gone and I don’t know where to find her.“ Cas cleared his throat to catch Crowley’s attention "I found her once I can find her again, we just need you to tell us how to get the cure.” Crowley chuckled “Thanks to the little angels act y/n is probably off to find a witch to ward her against angels and demons.” Dean snapped Crowley “Just give us the cure and will bring y/n back here and fix her!” “Fine,the cure is 2 pints of human blood blessed by a priest,1 pint of demon blood, and a pint of an angels vessel blood,mix those together and just inject her like you would to cure a demon."Crowley said. Dean looked over at Cas and asked him "Can you give us 1 pint of your vessels blood?” Cas just nodded. Dean continued “Alright,now Crowley can you give us the demon blood? Also why do we need a angels vessel blood isn’t that human blood?"He just laughed"Of course I can get you the demon blood I am the king of hell,and for the angels vessel blood since angels don’t bleed the thing close enough to be holier than angel blood is the vessels blood since it contains the angel.” Dean nodded and said “Crowley get the demon blood and meet us back here in 6 hours will get the rest of the blood we need and Cas go find y/n.” Crowley snapped his fingers and was gone,suddenly a flutter of wings was heard and Cas was gone, now all Dean needed to do is get the human blood and bring it back to the bunker.The only thing in his mind is that there was a chance to change you back.Maybe...
