A/N : Originally a Oneshot. I really liked the bartender, so now, I'm going to make her live. So…the story and slightly AU but there are spoilers for Sin City. I do not own Supernatural ( I wish I did )

The Humane Demon

"Damn it" he cursed out loud in his head. Not only did he fail to exorcise the demon back to hell, he's stuck here with her. Dean only hoped that Sam would reach here first while he might just spend some quality time with Casey.

"We might as well be civil" Casey suggested. Dean seemed to ponder this. Sure she is pretty, but nevertheless a possessed girl. Dirty thoughts flew from him as he only saw her as a demon – an evil. He sat on a barrel, looking at his own surroundings. Rocks piled up the basement and there were neither windows nor reception. The air is mostly stale and musty, with a slight stench of blood from Riche's murder the day before. If not for his sensitive nose of the smell of blood, he might not even notice it. Luckily, the tiny little chimney-sized opening provided some form of ventilation.

They talked about the current situation, a war without a front, without a leader ,without the tyrant, Azazel. Stupid bastard had a name. Yellow eyed demon suited him more. He was sneaky, possessed his father even acted like him. Such a creature like him should not have even existed, let alone be named. Casey mentioned that all the escaped demons are now fighting for ground as chaos ruled the earth since Sam, the chosen 'adversary' as Ruddrick has put it, is not quite up to the position. Dean was silently happy about this though. He would prefer to face the chaos with his Sam than a world of darkness led by an evil brother he once knew and protected.

He admitted that selling his soul to the devil was rather…liberating. He could now put his life at the war front and be reckless since there was no future to worry about. In addition, he need not control his unhealthy indulgence in greasy food and chocolates. Bobby once chided him for having bacon cheese bagel for breakfast but he "ain't sweatin' the cholesterol".

Looking at Casey once again, Dean could not help but feel a connection between the two of them. Though a demon, she did not seem cold hearted like Meg or the Seven Deadly Sins. She had feelings of loyalty, love, admiration, faith. It made Dean wonder if demons and humans were any different. Yes, they were more scheming, with freaky powers and unnatural black eyes, but they too worshipped a God of their own, Lucifer, and had families and lovers. He could remember that he had pissed off the yellow eyed demon by 'killing' his daughter and son. Also, for the record, Casey was ready to follow Sam in the war until the big plan fell apart.

Out of the blue, Dean asked Casey, " Hey can I ask you a question?"

"I'm an open book" replied Casey.

"How is it like down there" he asked casually, though deep down he really felt that it is an important question. He was curious, maybe afraid. No one will be down there with him except for those demons he had ticked off all his life. Even his dad had already climbed out of Hell. Casey then remembered that Dean had gotten a one way ticket down there.

Her eyes are filled with fear as she says, "Oh, you won't get the presidential suite…why do you think we want to come up here". There, his question is answered. Hell is a place of constant agony, torture, devastation. Dean shuddered at the thought of it.

Casey broke the silence, "You're…likable".

Dean was astounded at her words. "Whoa, a demon likes me… I don't know how to respond to that".

"You could say 'thanks" Casey suggested and Dean gave an appreciative nod. She was the first pretty girl/demon that had ever liked him for who he was, not like some other girls he charmed or some other demon who would kill at the sight of him. For that once in a long time, he felt that he was worth something. Casey had openly expressed that she thought he was brave when he made that deal even if the others thought it was stupid. She had her own mind, not some sickening lackey of Azazel. He was kind of glad that she referred to him as a tyrant. It roughly meant that she hated him to a certain extent as well.

He might just agree with Casey that humans aren't "a lovable bunch". All the poltergeist, shape shifters, murderers, and the list go on, they are all of mankind, with a human heart but with no conscience, only anger and selfishness. Demons and humans kill, so why is it that demons should be sent to hell just because they have abilities but not humans? So maybe...not all demons are evil, just like not all humans are good. Casey remarked that mankind had killed a number that amazes even them.

As she lazed around in the Devil's Trap, her body moved with elegance, her curves are something to drool over indeed. "My, Dean! If I didn't know the situation, I would have thought that there was lust in your eyes". Actually, there was, but he will never admit it anyway. If not for the circumstances, he would have made friends with her, but right now, they are just from two different worlds.

Faraway, the sound of engine neared and died. The car has stopped. "Sam?" He called out. "Dean! Where are you?" Sam screamed. "Over here! Be careful Sammy" Dean shouted albeit not too loudly. The feeling of hope arised within him yet at the same time he could not bear to leave Casey - not immediately that is. He originally wanted to spend the night talking to Casey, but too wanted Sam to come rescue him. Conflicting emotions struggled within him, threatening to tear him apart.

"Looks like you win" Casey said. She was neither afraid nor angry. It was more like she was fine with the fact that she would die just like that. At that moment, Dean thought she was brave as well.

After a while, the pile of rocks blocking the exit fell and to his surprise, it was the 'holy' priest that came through, but his eyes were of a demonic black. How ironic, really. Casey stopped him from entering the Devil's Trap as he bent down and made a crack, breaking the containment circle. With a flick of a wrist, Dean was flung against the stone wall and crash down onto the empty barrels. He stood up just in time to see the priest and bartender kissing passionately, holding each other by the face, all to engrossed to attend to Dean at the moment. To tell the truth, he was slightly hurt that Casey had a lover. The sight was disgusting, like come on, a holy priest and a sleazy bartender? What an insult to Christianity!

He pointed at the two of them with incredulously, "You two are together?"

"Yes, for centuries" the Father replied as both of them looked at each other lovingly. However, within a split second, Dean was held up above the ground by the neck by the priest as Casey tried to dissuade him from killing Dean as he struggle to breathe through the tight grip clasped around his throat.

"Don't kill him! Let him go!" she screamed.

Dean was touched. Never in his life he'd imagine a demon beg for his life. Before anything was done, Sam rushed in with the Colt and shot the priest in the head. His body convulsed and statics circulated his bullet wound. The light in his eyes went out as he fell to the floor with a loud thud together with Dean.

Dean feared for what is to come. Sam is going to kill Casey. The demon who cared for him. He panicked and adrenaline pumped through his veins as his quickly picked himself up and stood in front of Casey, facing Sam, looking into his eyes. What he saw scared him. Sam's eyes were cold and unfeeling; he just killed a human for goodness sake. The person in front of him was nothing like his sympathetic Sammy. The yellow eyed demon's words ringed in his ears, "Are you even sure that what you brought back was hundred percent Sammy?". Maybe Azazel was right. Maybe…..

"Dean! What are you doing?! She's a demon" Sam exclaimed, interrupting his thoughts.

A dark look fell on his face. "Sammy, let her go. We'll just leave ok?" Dean pleaded.

"Have you been brainwashed or something? How do you even know that she wouldn't hurt anyone in future?" Sam retorted.

"Please Sammy, Please…" Dean tried again but to no avail. Sam continued to point the Colt in her direction, ready to pull the trigger at any chance.

Dean isn't going to give him one. Casey made him feel important, admired, or even loved and he was not about to waste her with the Colt and he made a choice. "Casey, leave this body now, GO!...before Sam shoots you" Dean asked with a hint of urgency in his masculine voice. He turned around to look at her, while noting for any movement from Sam. She was surprised, her eyes shone with gratitude. Dean could hear Sam asking him to get out of the way but he could not care less. Hell with the Stockolm Syndrome.

"Thank You Dean. I'll always remember you" and she left as a black smoke through the beautiful girl. She is gone now, but at least she's alive, or sort of and he's happy for that reason alone. Relief filled his mind and Dean kneeled onto the floor as the effects of adrenaline faded away.

A tear slid down the corner of Dean's eye as he swiped it away. He will miss her.

"What the hell is wrong with you, Dean" Sam scolded angrily. Dean knows that Sam will never know how he felt. The loneliness, insecurity he grew up with. The solid mental walls his built masked it all.

"Shut up Sam, like you ever killed Ruby" Dean snared.
