Where it All Began (All)

Evil TFW
******************
You and the boys (Sam, Dean, and Cas) had discovered a nearby case. It didn't seem too difficult, so you figured you should get it out of the way while on your break. All of you had followed the creature to an abandoned wear house.
"Stereotypical huh?" You joke, Dean chuckles as he presses himself against the wall.
Sam is in front of you and Cas is behind, almost creating a protective barrier "On three." Sam whispers "1, 2, 3!" The brothers simultaneously kick the door, causing it to break open.
Everyone rushes in, guns loaded and looking around, only to be confronted with darkness. Cas steps closer to you as he pulls out his angel blade.
"Be careful, I sence something dangerous here."
"It's you." A voice echoes, causing everyone to instinctively step closer to you.
"It's who? Who are you?" Sam calls out, looking around as the door closed behind them.
"If I were her, I'd run." The voice chimed as all three guys started gripping their heads in pain.
You were about to grab Castiel's shoulder, but stopped when you saw the red marks growing from his neck up the side of his head. Shaking your head, you backed away before turning and running full force away from the group. After running through the maze of equipment throughout the building, you stopped to breathe.
"What..." you huffed "What did you do to them?" You called to the voice.
It replied with a chuckle "The question is, what did they do to themselves? Everything they did to themselves is imploding on them as we speak. Sam's demon blood, and souless personalities. Deans time with the mark of Cain. Castiel's time as god, with those nasty monsters eating him alive from the inside. They did these things to themselves, and now you get to see all of them fight to the death, all because of you."
You began to shake in fear "Why because of me? What did I do?"
"Because you exist dear girl. They all want to protect you from the monster, but the others are the monsters. They are all fighting to protect you from the others. At least you don't have to worry about them killing you." He laughed, causing a tear to roll down your cheek
"So Soulless Sam, Demon Dean, and God Cas are all trying to save me from the others?"
"Well Sammy boy also has his demon blood affliction, to make things more interesting."
You open your mouth to speak, when you are interupted by a voice echoing from somewhere near you "(Y/N)? Where are you?" It was Dean, but something was wrong.
"Sammy is chock full of blood right now. Oh, and don't forget that Dean has the first blade too." The voice chuckles.
Slowly, you sneak along the equipment, trying to stay away from him. You turn around to see if he is behind you, but don't see anything. You are about to turn back around when you run into something. Something warm.
Quickly, you turn towards it and back away on your knees "There you are." Sam kneels next to you "We have to get out of here."
"Sam, what are you-?!" You shout.
He quickly tries to shush you, but is stopped by a chuckle from behind him. You and Sam look to see Cas tilting his head with a smile. Sam stands and tries to hit him, only to have Cas catch his hand and throw him to the side.
"You will come with me." He forcefully grabbed you and threw you over his shoulder.
"Cas! This isn't you!" You scream and try to squirm from his grip.
"That's not yours." A voice chimes, catching your attention.
You look up to see Dean, a blade made of a donkeys jaw in his hand. Your eyes meet his, the beautiful green disguised by a dark black.
He blinks them away then steps towards you "Hand her over."
Cas turns to him with an insane smile "Come get her."
Suddenly you were knocked from Castiel's hold and on the floor. Sam had tackled Cas and forced you out of his grasp. Dean laughed and grabbed your arm "Lets get out of here."
"Not so fast." Sam growls, now standing.
"Hey Sammy, you want her?" He chuckled, gripping your arm tighter.
Sammy cleared his throat, straightening his back with a smirk "Your a demon, Dean. Remember what happens when I'm around demons?"
Suddenly Dean let you go "You wouldn't hurt your big bro would you?" He chuckled nervously, gripping the blade.
"No soul means no empathy. I couldn't care less if you were half dead in a ditch."
"Guys please!" You yell, running in between the triangle of guys "This isn't you! This needs to stop before someone kills someone!" You shout.
"I'm afraid that isn't how it works." The voice booms across the space you all had become confined in "Either they kill each other over you, or they all team up to kill you. Which would you rather choose?"
