Malevolence
You stormed out of the bunker and made your way to the road, your blood still boiling. You realized that the air was incredibly thick and your surroundings were eerily quiet. Something was off, you sensed it. Dean and Sam crashed through the bunker door and immediately sensed it as well.
"(Y/N)!" Dean called out, hoping you would heed the warning in his tone.
"Dean...something's not right.." Sam said with a low voice.
Dean didn't take his eyes off you as he started to wearily make his way to you and Sam followed closely behind him. You slowly turned to face him while checking your hips and jacket for any weapons you may still be armed with, only to find there was nothing. You were unarmed. Just as you were about to sprint towards Dean and Sam you were swept up into a current of energy that sent you flying through the air and crashing into a solid tree.
"(Y/N)!" Sam and Dean yelled in unison as you growled in pain.
Both started to run to your aid, weapons drawn when 3 demons appeared before them. The demons eyes were black as coal and all 3 of them dawned conniving smirks across their faces. Sam and Dean swallowed hard realizing they had nothing but their guns. No angel blades. No rock salt. Nothing that would send these son of a bitches back to hell.
The 3 demons started to draw closer.
"Alright, 3 of you, 3 of us...odds are even. You uglies don't have a damn chance." Dean warned them.
"(Y/N)! Get up!" Sam called to you.
One demon stepped forward and spoke with such arrogance in his voice.
"Even you say?" The demon smirked hard. "We'll lets change up the odds, shall we?"
Sam and Dean began to hear foot steps approaching them from behind, They both turned fast to see 3 more demons at their backs. Then past the first 3 demons that appeared another demon before you at the tree you laid beneath. You struggled to get to your feet but was kicked back to the ground immediately. Sam and Dean knew they had to fight their way out of this someway. Dean began to growl deep in his throat as he watched the demon that hovered over you kick you back to the ground.
"You idiots should have never trusted Crowley enough in the past to let him know where you're hideout was." One demon snickered at Sam and Dean.
"So then where's boss man? You goons are here, he can't be far behind." Dean snapped sarcastically.
"He's got more important things to do. You no longer are his concern nor does he care enough to deal death to you HUNTERS any longer." The demon continued. "We can take care of you Winchesters."
"So what you're saying is Crowley is too afraid to deal with us.." Dean snapped again. "Once a coward always a coward."
"Your death wont be quick, Winchesters!" The demon barked back at Dean while all of them closed in on Dean and Sam.
The other demon hovering over you once again waited until you got to you're feet and slammed you back to the ground with hard kick to the side. You tried to catch your breath since he knocked the wind out of you and lifted yourself once again. The demon who was bullying you chuckled at your perseverance as you rose to your feet. He swiftly grabbed you by the throat and slammed the back of your skull against the tree and tossed you into the middle of the road. You held the back of your head and scrambled back up to your feet, having enough. Dean watched the demon kick you around and for whatever reason grew more enraged and protective. Dean growled and sprung into action hitting one demon in the face with the butt of his gun. Sam followed suit and threw an elbow and a direct hard puck to 2 of the demons that stood behind them.
As the boys went to combat against the 6 demons that surrounded them, you aimed your focus at the demon who stood before you. Readying your fists. You narrowed your eyes and growled.
"Play time's over, you son of a bitch!" You snapped as you stepped forward and swung a hard right fist into the temple of his skull. He flew through the air and landed hard against the pavement.
You took the chance to dart over to him, repeatedly stomping on his skull, con-caving it. Your brute strength splitting his head in two. As the demon's vessel's brain matter was mashed into the road you turn to see Sam and Dean in their scuffle. Clearly out numbered. You rushed to their aid when a bight flash of light nearly blinded you. After your eyes re-adjusted you took notice that all the demons had disintegrated within that flash of light. Where the demons once stood a new man stood before Dean and Sam. He wore a long, tan trench coat and had a very serious demeanor. Sam and Dean looked relieved.
"Cas.." Dean said with a deep sigh as Sam dusted himself off and walked towards you to lead you back to the bunker.
"Dean...Crowley only needs 3 more shards. He is using what he has to make himself and his demons stronger." Castiel replied with a seriousness in his voice.
"Great! No wonder why his demons are kicking our ass." Dean groaned.
Sam and you approached Dean and Castiel quietly. Castiel took notice of you and stared you down coldly. Dean raised an eyebrow at the way Castiel looked at you.
"Cas...this is (Y/N). She helped us out in a confrontation with Crowley." Sam introduced.
"Good old (Y/N), here, saved our asses." Dean interjected.
"Mmm.." Castiel turned and looked at Dean, warning in his eyes.
You, Dean, Sam, and Castiel made your way back into the bunker and Dean sealed the doors tight. Castiel looked at the table you had destroyed before walking out of the bunker earlier and narrowed his eyes at you. You noticed his suspicion with you and decided to nip it in the ass. With an annoyed sigh you started.
"Alright angel feathers, what's your problem?" You asked, letting him know you knew he had an issue.
"Angel feathers?" Castiel asked confused. "...But you can't even see my wings."
"I know what the hell you are. It isn't hard to figure out." You rolled your eyes when you saw that Castiel wasn't following. "I can see them...as well as your grace."
Castiel stood in shock, although his face didn't reflect it. Sam looked at Castiel raising an eyebrow then turned his gaze to you.
"Wait..his grace? You can see his grace? How is that even possible?" Dean questioned.
"Well obviously whatever Rowena did to (Y/N) made it possible to see those sort of things.." Sam answered.
"But only other angels and demons can see each others true form..." Castiel stated accusingly, Narrowing his eyes at you once again. "...And you are no angel..."
Castiel walked to a bookshelf while he was finishing his statement, quietly grabbing a flask of holy water and discreetly tucking it under his arm. Cas returned to the table and swiftly revealed the flask of holy water, flipping the top open and splashing you in the face with the water. Sam and Dean jumped back some questioning Castiel's intentions.
You didn't flinch at the holy water, only looked back at him and slightly sucked your teeth in irritation. You wiped your face and stared Castiel down hard, not saying a word. Dean jumped to your defense immediately.
"What the HELL Cas!? She may not be an angel but she sure as hell isn't a demon either!" Dean barked.
Castiel looked down slightly and dropped the flask on the table. He looked at you through apologetic eyes.
"My mistake..." he nodded towards you.
"Cas, (Y/N) isn't a demon or an angel or anything else for that matter." Sam reiterated. " But Rowena did something to her, drained all the light from her. Now she's fighting some sort of darkness or evil within her."
"I don't understand...." Castiel confessed.
"Ok...Think of Dean with the mark or Cain. How he had to control the evil in him that the mark caused...like that." Sam continued.
"Pretty much, except without the demonic blade and scar." Dean chimed in.
"But it was caused by Rowena, so with her being a witch I'm going to assume it's a spell." Sam said while he came to his conclusion.
"If it's a spell, maybe Cas can get rid of it." Dean suggested looking at you and then Castiel.
"He just splashed me with holy water..." You growled. "He couldn't even figure out if I was a demon or not and you expect me to trust him with my soul?"
Castiel thought for a moment, then spoke.
"I suppose that I could possibly cleanse her." Castiel said.
Dean walked over and placed a gentle hand on your shoulder.
"It's worth a shot..." Dean assured.
You looked at the 3 of them not convinced but you knew something was growing inside of you. Something that if it took over the real you would be gone. You just wanted revenge when you made a pack with Rowena. Only to find out she was playing you. It was evident that all she cared about reassembling the Onyx only to gain what Crowley was aiming to achieve. You took a deep sigh as you prepared yourself for what Castiel was going to attempt.
You nodded after running through everything that had happened in the past months in your head.
"What the hell...even if it goes wrong, I'm sure I've been through worse." You sighed.
"Atta girl." Dean encouraged, squeezing your shoulder.
Sam grabbed a chair and dragged it over to the center of the room while Castiel signaled for you to sit. You took a seat and shifted in the chair, already feeling the stress. For some reason you're body started to react inside. You felt it in your chest. Like whatever evil or darkness that was inside of you was becoming agitated, sensing an angel was going to use his celestial powers against it. Castiel sensed this as well. He looked at Dean.
"You may want to restrain her..." Castiel warned.
Dean opened his mouth, almost to question Castiel, But instead said nothing. Dean removed his belt and Sam removed his, handing it to Dean. Dean then knelt before you and
looked you in the eye and watched you intently.
"Sorry..." He said softly as he began to use the belts as straps and tied your wrists to the arm of the chair tightly. Then a smirk crossed his face and he raised an eyebrow are you. "
This would be a lot better if it were under different circumstances."
You smirked slightly back at him although you weren't sure if it was because of his joke or if it was your nerves. He finished up an stepped away allowing Castiel to approach you. Castiel raised is palm and placed it to your head, a low light began to glow from the connection of his hand to your forehead. Immediately you're body began to react more violently. You could feel a heat welling up inside of you, twisting and turning inside of you. It became stronger and hotter, Your breathing became heavy and rapid, and you could feel this darkness rise up to your skull. It began to feel like you we engulfed in flames. Finally you threw your head back violently and your eyes rolled in the back of your head. Sam and Dean stood back watching, concerned. Castiel began to seem as though he was physically battling something. His brow was furrowed and his teeth were gritted. He let out a growl as he forced more light through the contact between the two of you. On your end a flood of rage, power, guilt, regret, and malevolence raced through your body and you let out a blood curdling scream and you began to fight against Castiel. You began to wrench your arms back and forth until finally a mass amount of power gave you the strength to rip your arm free from one of the belt restraints. You grabbed Castiel's arm and looked him in the eye. Your eyes were empty. No emotion ran through them. While gripping Castiels arm you threw him through a wooden bookshelf on the other side of the room and began to rip your other wrist from the chair. Dean and Sam then jumped into action.
"Cas!" Dean yelled while he ran over to you and pinned your arms back down with his own hands, using his body weight on top of his hands.
Sam ran to Castiel's aid while Dean continued to struggle restraining you. You started to give up fighting when you began to go into convulsions. Dean ripped you from the chair and to the ground, while he craddled you through the seizure.
"(Y/N)!" Dean yelled in your face trying to bring you back. "God damn it! Come on!"
Castiel managed to get back to his feet, astounded by what you just accomplished. Sam now ran to Dean and you. Both Winchesters trying desperately hard to pull you back from this seizure. Dean kept trying to talk you down until finally your body began to relax in his arms. Your breathing slowly regained a normal pace and your body ceased violently jerking. He continued to cradle you close to his chest whispering for you to come back and relax. Eventually, in his arms it was almost as if you were just in a deep sleep. Dean turned his worried gaze to Castiel. Castiel came over to check on you, hesitantly he placed two fingers on your forehead and looked back at Dean.
"She's unconscious....but she will be alright." Castiel assured.
Dean turned away from Castiel and placed his chin against your head while he continued his embrace.
