Sam and Castiel left the impala and traveled to the factory on foot, trying to stay undercover. After they spoke to Kevin, who told them what he believed had happened; they tracked a few demons down who unwillingly told them where Crowley might be at, but upon getting there, Castiel said he felt Dean within.
"Can you enter?" Sam asked, and Castiel nodded.
"Yes, I can…but not in the room where I feel Dean at. There's a sigil in the room Dean's at, it's going to prevent me from entering, and it'll need to be destroyed before I can enter." Castiel explained, and Sam nodded as they walked along the fence surrounding the building
"What I want to know is why there isn't more than one sigil that prevents you from entering? Did they think we wouldn't find them?" Sam asked, and Castiel hummed.
"Maybe, the demons did say it was impossible to find the place; that they shouldn't tell us were Crowley was. My thought is death scared them so much they decided to speak rather than die." Castiel commented, and Sam shrugged.
"Maybe, come on. I see an opening over there." Sam said and the two ran toward the hole at the bottom of the fence.
As they got inside, after killing a few demons, they walked toward the area Castiel said he felt Dean at. It surprised Sam that Castiel could tell where Dean was, considering the branding he placed upon their ribs; but Sam suspected it was because of their 'profound bond' that they used to excuse their over-friendliness towards the other. He was tired of their small touches, lingering looks, sexual tension, just about EVERYTHING going on between the two was killing Sam…especially the eye-fucking. Seriously, it was like the two tried to undress the other with their eyes.
"Where is he Cas?" Sam asked Castiel, his panic slowly rising back up again.
"You have to understand Sam the sigil is messing with my sense's at the moment, it's hard to pinpoint where Dean is." Castiel murmured as he tried to listen to where Dean might be.
Suddenly they heard a scream further down the corridor, and stopping to look at the other in shock, they ran down the hall, heading toward the sound as they heard it again. Sam soon smelt burning flesh, and nearly recoiled in disgust, but he pressed forward; his brother's life was at stake…again. They heard the scream again, and Castiel recoiled away from a door and Sam looked at it. This had to be the door that had the sigil on it, and Sam cursed…it'd be hard to break down since it was metal…but the bomb he had might do the trick. It wasn't a demon-bomb, but it did help when it came to breaking down doors. Sam placed the bomb, before grabbing Castiel and they moved toward the corner right as the bomb went off. They both ran through the door, and gasped as they saw black smoke going inside Dean, and Sam's eye widened in horror…but the tattoo!
"Ah yes, better. Now that the marking on your chest is gone it seems to be a lot easier in taking over your body." The female demon said as she spun the iron rod in her hand, some flesh still sticking to the burning tip.
"NO!" Sam shouted and shot off a salt-bullet at the female demon.
She shrieked as the bullet got her in the head, and she fell down with a thud, and Sam ran toward Dean as Castiel dealt with the other two demons.
"Dean? Dean, listen it's me Sam." Sam said as he watched his brother try to fight the demon invading him off.
"Sammy, get back!" Dean warned, throwing his head back against the chair, clenching his hands into fists, and shutting his eyes shut tight.
"What happened?! How did it get you?!" Sam shouted, before he looked at Dean and saw the condition he was in…before he noticed something was missing.
The anti-possession tattoo on Dean's chest had been burned off…literally. Sam looked at his brother on the verge of crying…his brother was fighting a demon, and might end up losing.
"Come on Dean, fight that damn thing!" Sam encourage, resting his hands on his brother's shoulders.
"Sammy, get away!" Dean shouted, but Sam refused to bulge.
"No Dean, I'm not going to back off. I'm staying right here, I'm going to help you fight this!" Sam shouted as Castiel came over.
Sam began chanting off the removal spell, but Castiel stopped him.
"No don't! The demon has grabbed hold of Dean's soul, if you force the demon out of Dean, the demon could easily take Dean's soul with him." Castiel said as his eyes glowed blue.
Suddenly Dean stopped moving, his head falling forward; and Sam with Castiel watched Dean cautiously, wondering who won.
"…Dean?" Sam asked after some time passed, tilting his head a bit.
Sam suddenly was thrown against a wall, and shouted as his back made contact with the stone wall. Castiel looked back at Dean after seeing the act, only to feel something try to push him back; but he threw a hand out, stopping the demon power. Suddenly the bindings holding Dean broke, and he looked up at Castiel, his eyes black and he smirked as his wounds healed. Castiel stared at Dean with wide eyes, his blue eyes showing horror at what happened to his best friend.
"Hello…Castiel, correct?" Dean asked, being controlled, and Castiel nodded slowly.
"How do you know me? What did you do to Dean?" Castiel asked, trying to see if he could see through the black eyes into Dean.
"Dean's bound at the moment, and I, Kartesh, decided it'd be best if I just…take over...for a bit. You see, I'm Crowley's right hand demon, I do anything he asks…and even he has a slight fear of me should I turn. But seeing as I'm allowed to do whatever I want, whenever I want, I can't complain." Dean/Kartesh said, who grinned as Castiel glared. (I will be calling Demon! Dean Kartesh from now on. So whenever Kartesh is mentioned, think Dean with black eyes.)
"Leave Dean's body now!" Castiel commanded, but Kartesh laughed loudly, before thrusting a hand out and Castiel slammed against a wall.
Kartesh raised his hand, lifting Castiel in the air, who grunted as he tried to break the power holding him.
"I wouldn't resist if I were you…you might anger me enough to destroy Dean's soul. You see, with his body having been weakened and his soul having been tortured it'd be no problem for me to destroy his soul. Especially seeing as I'm inside the body, and I'm holding his soul at this exact moment…I'd say it'd be unwise…for you to anger me at this moment." Kartesh said before his black eyes turned green.
Castiel dropped to the floor and grunted at the impact before looking at Kartesh/Dean, seeing him holding his head.
"No…leave my body!" Dean shouted as he gripped his head tighter, trying to push Kartesh out…but the demon refused to budge.
"Sorry Dean boy, but I like this body too much to think of leaving. Besides, I was given a job to do…your brother and his angel have to die, and due to the agreement; Crowley can't hurt them, but this is your body, not Crowley's or a demons, so this doesn'tinterfere with the agreement. Because youwill have killed them, not Crowley." Kartesh said in Dean's head, who growled.
"Dean." Castiel said softly, before he gripped Dean's arms.
"Cas…g-get away from…me. Kartesh…h-he'll k-kill you, and S-Sammy!" Dean stuttered out in pain as he fought the demon.
Dean tried to push away from Castiel, but Castiel only tightened his grip; before he pulled Dean into a hug and embraced him tightly.
"I'm not going to let you run away Dean, I'm staying right here. I will help you fight Kartesh off…please, let me help you." Castiel said, before he laid his hand over the mark on Dean's shoulder.
Dean went rigged and leaned into Castiel more, the touch sending jolts of pleasure through him at the simple contact as a gasp left Dean's mouth. Castiel was shocked about the reaction, before he realized that had actually been the Mark he left on Dean that he touched. He looked at Dean, seeing that while he still fought the demon, his mind was on Castiel, the thought keeping Kartesh pushed back.
"I WILL NOT BE OVERCOME!" Kartesh shouted in Dean's mind, causing Dean to stiffen.
Dean pushed Castiel away, before he backed into the chair, and gripped it tightly.
"Cas…g-grab Sammy, and…l-leave…before Kartesh…k-kills one of y-you." Dean said, and Castiel was about to protest, but Dean shook his head.
"DO IT!" Dean shouted as black slowly overcame his eyes.
Castiel gritted his teeth, but walked over to Sam, and helped him up.
"Cas…D-Dean…" Sam mumbled out, blood dripping from his head.
"Dean…I'll be back for you…I promise." Castiel said, and the sound of wings him and Sam were gone.
"Don't come back for me…it's useless." Dean said, before his eyes turned black, and he snarled.
"Damn you Dean, letting them get away." Kartesh said once he completely gained control.
The door opened up, and Crowley walked in; before he smiled at seeing the blacked eyes of Dean.
"So…you like the body?" Crowley asked, and Kartesh nodded, rolling the shoulders.
"A little tight, but that'll be fixed as times goes on. What'd you want me to do in this body?" Kartesh asked, and Crowley smirked.
"Search Dean's memories, try to find out where the location of God's Weapons are. We will need those weapons if we wish to kill all the angel's and control Heaven, Purgatory, Earth, and keep control of Hell." Crowley said smiling widely, and Kartesh smirked.
"Alright then, I'll see what I can dig up from his mind." Kartesh said, before he walked toward Crowley with a nod.
Next Day with Sam: Sam sighed as he closed the last book he had, before he looked over at Castiel, seeing the far-off-look in the angel's eyes. Ever since they got back yesterday evening Castiel had been silent, never answering whenever asked a question, not responding to anything that would usually get his interest…not even mentioning God's Weapons got his attention. It suddenly made him wonder…why did Crowley want Dean? They never got to ask him that question, and Sam had been rendered unconscious once he had hit the wall.
"Hey Castiel, who knew about the location of Gods Weapons aside from Balthazar?" Sam asked, knowing he might not get a response.
"No one except Balthazar, though he did frequent you two a lot after he hid them." Castiel said, his voice rough from not having used it for hours.
Sam was surprised to have received a response…but the answer confused him. Balthazar frequented them? When? Why?
"He did? Me and Dean never saw the guy, nor did we heard, or feel him nearby. We usually had to summon him." Sam stated, and Castiel looked at Sam tilting his head.
"That's impossible, he constantly told me he spoke to you all whenever he'd leave for hours." Castiel said walking toward Sam and sitting before him in the chair across from him.
"Yeah well…never did see him myself unless we summoned him. Why did he visit us?" Sam asked, suddenly curious to know the reasons.
"He always said something about Gods Weapons…did he ever tell you two anything?" Castiel asked, but Sam shook his head.
"No, he never said anything to us about them…unless…" Sam went quiet as he began typing away on the laptop before him, his fingers moving swiftly over the keys.
Suddenly Sam smiled as he came upon the camera he had in his computer, and searched through the files. He usually had his computer's camera on some nights whenever they were at a hotel incase anything ever happened while he was asleep. He watched some of them, usually fast forwarding through them, until one caught his attention.
"Whoa, whoa, whoa what's this?" Sam questioned, catching Castiel's attention.
"What is it?" Castiel asked as he circled over to Sam's side.
"Watch this." Sam said as he clicked play, and turned it toward Castiel.
The screen showed Balthazar appear and looked around cautiously, before making his way toward Dean, and knelt down. He placed two fingers against Dean's head, and mumbles something in Enochian that Sam couldn't understand, and due to the bad quality, Castiel couldn't understand it either.
"Sorry Dean, but you're really the only one I can trust about in showing you the locations of the weapons. Sammy too…unstable to process the thoughts to him, and Castiel is losing his mind as his thoughts are only on defeating Raphael. Besides, I have complete faith in you Dean; I know you'll be able to keep it a secret…even from an angel or demon."Balthazar said, before he disappeared…then they saw Crowley.
"So, little birdie did something to Dean…well, let's see what it was. AH!"Crowley shouted a little in pain when he tried to see the memory, but something blocked him.
"I see Balthazar put a lot of effort into hiding that from anyone. Till next time Dean-o."Crowley said before he disappeared.
"Balthazar implanted a memory into Dean's mind to keep the secret hidden. He knew Dean was good at hiding things, seeing how Dean buried memories deep down inside, and never really brought things up in conversation's unless forced." Sam said with a slight chuckle as if he had figured out a great secret, pausing it.
"That must be why Crowley kidnapped Dean, he knew Dean knew the locations. It would seem to me though that Dean is unaware of this from his actions." Castiel explained, and Sam nodded.
"I noticed that as well, Dean hasn't spoken, asked, or said anything related to the Angel's Weapon's ever since the incident when you…turned…against us." Sam said, hoping to not insult Castiel.
"If you fear insulting me don't worry, I am well aware of what it was I did." Castiel said as he looked at Sam, who sighed with a nod.
"Alright…in the meantime we've got to try and find a way to get Dean back to normal. I got some calls I need to make." Sam said as he grabbed his cellphone and began making calls.
