The Fallen

A/N: I got this idea last night while watching showtime on my tv. They show a ten minute 'sex scene' (the characters are definitely not having sex, but it completely looks as if they are) then they show about 10 – 15 minutes of plot, then sex again, then plot again. The acting is horrid, and the sex, while just like a porno in feel, you can tell the guy never actually penetrates the woman. I normally don't like Supernatural AU's but I got this idea and decided to go with it. In this story, Castiel is an angel, but he is a 'Fallen' which are angel's who commit a sin, and God forces them to Earth to repent. Until they repent for their sins truly, they cannot go back to heaven.

Castiel's sin was evny. He envied the humans and wished to be one of them. Castiel has just fallen; he does not inhabit a human body. i.e. Jimmy Novak does not exist. The body Castiel is in (the one from the series) is his own. However, Castiel only appears to be in his 20's.

Dean and Sam's mother died in a house fire cause by a demon, but they do not know it was a demon that caused it. Their father put them in a foster home and left to hunt the demon, not telling them because he wanted to keep them safe. In other words, supernatural beings do exist in this world. Dean is 18, leaves the foster home, and convinces the judge to allow Sam to come with him. Sam is still in school and Dean has to provide for the both of them. Also, the age difference is 2 years in my story, not 4.

Castiel looked down at the newspaper in his hands, then back to the door in front of him. This was the right address, he noted. Without hesitation, he knocked on the door, and after a minute, a man appeared, being sure to only crack it open a little.

"What?" He asked in a gruff voice.

Tilting his head to the side, Castiel replied, "I am here to inquire about a room."

The answer to his statement was simple enough, "You do drugs?"

To this, the Fallen gave the man a confused look, "No, am I required to?" The door closed and Castiel found himself even more confused at the man's strange behavior. He was about to leave when he heard the chain being removed and a second later the door opened all the way.

"I have to get to work. I'll talk for five minutes and if I don't like you, I'm kicking you out."

Castiel nodded, "That is acceptable," He answered in return before entering the very small apartment. He looked around in fascination – this was his first time in a human dwelling. There was a couch and a black and white T.V. in the living room, in the kitchen they had a stove, oven, fridge, but not much else. Castiel believe if he were to look in the fridge, there would be hardly anything in it. Only two rooms in the hallway, one to the left, one to the right, and a bathroom in the middle.

The human looked Castiel over, "It's not much, but it's our home. We don't usually let strangers in." He spoke quietly.

"We?"

At this, the human nodded. "I have a brother. He lives here with me." He then started to walk away, Castiel following behind, "Rent will be 300 a month, plus utilities. The room has a bed, but not a frame." He opened the bedroom door. "There is no dresser or closet, but it's bigger than the other room."

"These accommodations are more than acceptable. Do you wish for the money now?" He asked as he reached into his trench coat and retrieved a wad of money. "I am not sure how much this is," He handed the wad over to the human, whose eyes had grown wide in response, "Is it acceptable?"

The man stuttered for a moment, "There's…" He counted and his eyes grew wider, "1500 dollars here! This is way more than enough, man." Suddenly, his eyes narrowed, "How did you get this?"

"My Father," Castiel replied. He sat on the bed, testing how comfortable it would be. Smiling, he added, "Before he kicked me out, he wanted to know I would have some place to sleep."

"I'm Dean," The man pocketed the money, "This will cover you for 5 months. You can share food with Sammy and me."

"I do not require substance as far as I know." Castiel laid upon the bed, "Does this mean I can stay?" He then asked, staring at the ceiling.

Dean nodded, though he knew the Fallen could not see, "Yeah, you can stay. But any freaky stuff and I'm kicking you out. I gotta go to work now." Dean stared at the man for a moment before shaking his head and closing the bedroom door as he left. Tonight after work, he was going to finally be able to get some food for him and his brother.

Sam threw his book bag down on the couch and opened the fridge, not at all surprised when he saw no food. Sighing, he closed it, the note attached finally catching his eye. 'Sammy, new tenant, little weird, not a threat. Gun is in the ice maker. Dean' Sam rolled his eyes at his overly cautious brother. "Yo, anyone here?" He called out.

"Hello,"

Sam whirled around at the voice behind him. "Damn, you snuck up on me." For some reason he was tempted to reach into the ice maker, "You the new tenant?"

Castiel cocked his head to the side, "If by that you mean do I live in the spare room, the answer is yes," The fallen stepped closer to Sam, making the younger man step back. "You…have a very strong aura…" The Fallen reached for him, but stopped himself. "I apologize, to you I must seem to be acting…strange. I will retreat to my room now,"

Sam watched the man's back as he walked away, confused by the encounter. Dean was wrong, weird didn't even begin to describe the man. As he sat down to do his homework on the couch, Sam wondered why Dean and chosen this man – his older brother was usually overly cautious with the people in their lives. Whatever the reason, Sam decided, it had been a good one.

A few hours later, Dean returned home, arms filled with groceries. "There's a taxi downstairs with the rest. Go grab some stuff," He said gruffly, setting the stuff down on the counter. He looked to Sam, but his brother didn't more, "What?" Dean barked out to him,

The younger Winchester shook his head, then looked at Dean, "Did we win the lottery?"

Dean scoffed, "The new guy paid for 5 months."

"1500! Dude, that's awesome. Here I was thinking he was a creeper." The two brothers got the rest of the food, and Dean surprised same with a T.V. he bought at a pawn shop. It wasn't fancy or anything, but this one was at least in color. He had also bought a DVD player and a few movies with the money, and still had plenty left over for rent.

The two brothers were drinking some beer and watching some action flick when Castiel appeared in the kitchen. The brothers looked to each other, then back to the Fallen. Neither has seen or heard Castiel leave his room. "Yo," Spoke the older of the two, "You still haven't told us your name."

Castiel looked over at the two. "I am called Castiel." He replied before opening the fridge, "I have discovered that I do indeed require sustenance. What would you recommend? I have no experience in the kitchen."

Dean paused the movie and stood. "Well, sense you are the benefactor of this food, how about I make us all some grub." He smiled and walked over to his new roommate, placing a hand on the man's shoulder, "Why don't you go watch the movie with Sammy."

Nodding, Castiel finally smiled at the Winchester, "That would be most appreciated. I thank you for your assistance."

Dean whistled as he cooked. Living in the foster home, his foster parents rarely made dinner for them, so Dean took it upon himself to cook for everyone in the house, being that he was the oldest. There were two girls, and one boy besides him and his brother. Though Sam and Dean were the first to enter the foster home, Dean felt a connection to the other children instantly when they showed up. He protected them in school, kept them fed, he even bought them clothing and other things that the foster parents had no intention of spending their money on. Dean couldn't explain why, but he felt the need to keep them safe, to help them. Even now the older Winchester would stop by the house and leave things for the kids, making sure they were well looked after.

Looking over to the living room, he smiled at what he saw. Sam was laughing at something obviously funny, but Castiel's face was contorted in confusion. He said something to Sam, and it just made the boy laugh harder. Shaking his head, he finished the burgers and fries. "Yo, Cas! What do you want on your burger?"

"I've never had a burger. What does one normally put on it?" The Fallen asked with a tilt of his head. Again, Sam burst into laughter.

Shaking his head, Dean mumbled never mind and gave Castiel the works before bringing the plates in the living room for his brother and their new tenant. The three ate in peace, and Castiel surprised them by finishing his food in record time. "Did you like it?" Dean asked with a chuckle.

The Fallen nodded, "It was…delicious. Thank you for making it for me." He stood and took the others empty plates. "I will reciprocate by cleaning the mess."

When he walked away, Sam whispered, "He's really strange. Never had a burger?"

Dean nodded at this, "Yeah, but I think he grew up in a rich house. He said he got the money from his dad. They probably had cooks and gourmet meals. That's probably why he sounds so damn formal." Thinking about it, the older brother added, "That also explains the nice clothes."

Sam agreed, but also said, "Still, we should keep an eye on him," Both men looked over to Castiel, who was whistling the same tune Dean had been earlier that night, his back turned to them as he happily washed the dirty dishes.
