Dean Winchester, the man who survived Hell, had turned into the very thing he hated most. That killed him deep down, he didn't like that feeling. Why did he have a human emotion like that, he was so frustrated. He looked down at his brother who was passed out on the floor, with a bit of blood on his face. He felt bad, he didn't mean to do that, did he? The demon kicked his brother in anger. Ignore it, he shook the feeling off his back and dragged his brother into a nearby closet, then locked the door. He was not going to let Sam ruin the good news he heard. In all honesty he was being a downer to Dean. The demon decided to go out and get a drink at the nearest bar, since all the beers at his 'home' might actually hurt him now.

He sat down on a bar stool and placed his order, and while waiting for his drink he took a quick look around to see what pretty ladies might be around. He heard a flutter behind him and didn't even bother to look.

"Cas? You got your grace back fast." He took a sip of his drink that had just arrived. Castiel sat down on the seat next to Dean.

"Yeah, the process was nice and smooth. How are you feeling?" Castiel kept his eyes focused on Dean.

"Pretty good considering what happened." He took a quick look at the angel and then moved back to whatever he was staring at before.

"I'm surprised Sam let you come here." Castiel looked at the imaginary item Dean was looking at. "I'm confused as to what we are watching."

"Its a wall."

"Why are we staring at it then?"

"Look, Cas, Sam didn't let me come here." Dean and Castiel turned and faced each other.

"You left without permission?"

"What are you, a cop? I don't need permission." The demon chuckled at his own remark.

"Isn't Sam going to notice?"

"Yeah I should probably head back now." Dean winked at the angel. "Think I could hitch a ride?"

"Dean you-" Dean shushed Castiel with a finger in his face.

"Just once please, Cas, don't argue." Castiel chuckled and moved Dean's hand out of his face, and stood up.

"Okay okay, I'll take you back home but you have to buy me drink." Dean's smile grew and he nodded.

"Yeah, whatever you say pretty boy."

"You think i'm pretty?" Castiel sat back down and gave him a smile.

"...Yes Cas you are as pretty as a disney princess" Dean sarcastically said while shaking his head.

"Thank you" Castiel didn't seem to notice the sarcasm in Dean's voice, and Dean threw his head around in frustration.

"For pete's sake Cas Its an expression!"

"Disney princess?"

"No!"

When Dean and Castiel arrived at the bunker Sam had just busted through the door with just his body weight. Sam stumbled around, angry and had blood on his face, but when he saw Dean is when he really got pissed.

"Cas! Grab him!" Dean stood still when he heard these words and sighed, and Castiel hugged the demon from behind.

"Like this?"

"No! He knocked me out then locked me in the closet!" Sam grabbed his gun.

"Woah woah there, I'm sorry...I just lost control." Dean sighed, pushing the angel away.

"Sorry or not, it doesn't change the fact that you did that." Sam snorted and put his gun away. "Are we just going to take the heat from you or are you going to learn to control yourself?"

"I'll learn don't worry..."

The younger brother went to his bedroom and locked the door behind him. He sat on the edge of his bed and thought to himself for a bit about the situation. Knowing demons, no they wouldn't be able to control themselves, but Dean was not just a demon. He was human only a few days ago. Sam wiped the blood off his face and stood up, when he heard a gentle knock on his door. Carefully and slowly he opened it. He didn't know why but he was scared of what was behind it. A sense of relief washed over him when it was just simple Castiel. "Cas..." Sam sighed as he let the angel in and then lock to door again. Castiel sat down on the floor and Sam went back to where he was sitting on his bed before.

"Dean is not alright." Sam let the words pour out "He is a demon, he punched me down for no reason, he...he isn't okay Cas."

"I know. He seems to be putting up a front that he is ok. I can see through it, I did not want to upset him, he could kill me fast." Castiel looked down at the floor as he responded. "What are we going to do?"

"Cure him...Its the only option." Sam stared at Castiel, looking to see if the angel agreed or not. Castiel nodded and looked back at him. " Its going to be hard to do."

"Yeah... I'll get right on it."

Little did they know that right outside the door was the very thing they were talking about. Dean listened through the door and felt anger wash over him quickly. He did not want to be healed, he WAS fine. And Castiel was pretending? Dean hid when the door flung open and the angel left, walking down the stairs. Dean slowly snuck into his brothers room and closed the door behind him. Sam looked up and jumped, obviously startled by his brother suddenly being there.

"H-hi Dean."

"Sam." The demon growled, with the first blade in his fist. Sam looked at the weapon and swallowed.

"Uh, are you feeling alright?"

"Yes." Dean's eyes went black and he smiled, taking slow steps over to Sam. "But you won't be."

"Dean look I know you said you are sorry but you aren't you-" Sam barely got his last words out before Dean threw his fist at him, hitting him hard in the chin.

"Listen you FUCK. I am DEAN. I am OK. You obey me remember?!" Sam stood up to defend himself.

"Dean, NO! We are brothers thats not how it-" Another punch and Sam was down on the floor, trying to crawl away. Dean grabbed him by the collar of his shirt and threw rapid punches at him.

"I'm going to tear you to pieces..." He whispered to him before he took his brothers arm and twisted it, he didn't stop twisting it until he heard the snapping of a bone and Sam crying.

"Stop!" Dean did his leg next. Snap! Another leg. Snap! He took Sam's only good arm and broke his fingers one by one, taking in Sam's screams. Castiel knocked at the door.

"Sam?! Are you okay?!" Dean finished his work early by shoving his hand down Sam's throat and scratching him hard on the inside, clawing like a cat. He then disappeared, right as the angel barged in.

The damage was more then any angel could fix.
