Dean looked at the guy as if he was crazy. A fallen angel? Angels weren't real.' This guy must be high or something' Dean thought to himself. But the strange thing was that he was acting completely normal. Not loopy or anything. That must mean he is crazy.

"What's your name?" Dean asked.

"Castiel." He said and turned around to walk away. Dean reached out and grabbed his arm. Castiel stopped and looked back, tilting his head to the side in curiosity, "Yes?" Dean was once again flabbergasted. He was just almost hit by a car, and he was just going to walk off?

Dean wouldn't let his arm go. "What do you mean you are a 'fallen angel'?"

Castiel turned around, fully facing Dean. "I was wrongly accused of a crime in heaven, and I was stripped of my wings and grace. I am now fully human." He looked slightly sad at this statement. Dean was still convinced this guy was psycho. "Maybe we should get you to a hospital or something, are you feeling alright?"

Cas made another attempt to walk away. "I assure you, I'm not crazy-" He was cut off as wobbled a little and lost his balance, effectively passed out and starting to fall to the ground. Dean cursed and jumped to catch him. Looking down at the unconscious man in his arms, Dean sighed and lifted Castiel, placing him in the back seat of his car.

Starting up the car, Dean shook his head and asked himself, "How did I get into this?"

Parking Baby on the curb in front of his apartment, Dean dragged Castiel out of the back seat and carried him into the building and into the elevator, pressing the button for his floor. Now that Dean had a chance to think, he looked at the man he was holding.

He was dressed in a messy looking suit, with a too-big trench coat and a loose tie. He had a thin but muscular build, and had dark, tousled hair. Dean remembered Castiel's ocean blue eyes, and how hypnotizing they were. He could look into them all day.

Dean shook his head sharply. He had only met the guy, he shouldn't be thinking like that. And for all Dean knew, Castiel could've been a crazy serial killer. He sure seemed nuts.

They finally reached Dean's floor and walked down the hallway until they reached his door. He struggled to get his keys while still holding Castiel. He finally managed his way in, and set Cas down gently on his leather couch.

Dean stretched his shoulders and walked over to where he kept the liquor. He got a glass of whiskey, and sat down on a chair across from the couch Cas was on. He took a sip and started to think about the situation he was in. All he really wanted to do was take a hot shower and go to sleep, but he didn't know how long Cas was going to be out.

Right then, Cas shifted and let out a little moan. He sat up slowly and rubbed his forehead. He looked around at his surroundings and finally found Dean sitting on the chair. They both sat like that for a while, staring at each other. Until Castiel stood up and made a step to the door. "Thank you for taken me here, but I really have to leave." Right after he said this, he stumbled and leaned on the wall so he wouldn't fall over.

Dean shot up and led him back to the couch. "Oh no you don't. Just rest for a little, ok?" Cas looked reluctant but didn't attempt to get up again. After Cas declined a drink from Dean, Dean sat down in his chair and started to ask Cas some questions. "What exactly were you doing in the middle of the road anyway?" Cas looked down at his hands, as if he was trying to remember. "After I went unconscious in Heaven, all I remember is a strong heat and then I opened my eyes, and I was in the road."

'Oh great, here we go again with the Heaven crap.' Dean internally rolled his eyes. "Buddy, listen, there is no such things as angels. I don't know what you're smoking, but you really sound crazy, dude."

"I'm not 'smoking' anything; I assure you I was an angel of the Lord." Cas said, looking Dean straight in the eyes. Dean had to look away, becoming overwhelmed by his intense stare.

Not convinced, Dean looked back at Cas skeptically. "Prove it."

Cas seemed to become frustrated. "When I was angel, I would've been allowed to perform small miracles in order to prove my Father's power." Cas paused and thought for a moment. He face lit up and he looked at Dean. "Your name is Dean Winchester." Dean was taken aback. He didn't remember telling Cas his name, and he sure as hell never met this creep in his life. "Anyone could have found that out, I still don't believe you."

Cas then plunged into Dean's life story, getting everything right. Everything from taking care of his little brother Sam as kids, to his passion of cars and loud music. Dean just sat there with his mouth hanging open. It was like Castiel had been with him his whole life.

"How the hell did you know all of that?" Dean whispered, still extremely confused and slightly scared. He was scared because he was starting to believe Castiel. He feared he might be going crazy too. Nothing had ever been impossible to Dean. He never had an established religion, but he never really shot down the idea of Heaven and Hell.

"I've told you, I was once an angel. I was assigned to you, Dean. I was you guardian angel." Cas said, looking at Dean indifferently.

Dean laughed to himself. "This is insane." He couldn't believe he was actually starting to believe this nut job, but everything checked out. Castiel just sat on the couch patiently, and watched Dean as he paced around the room.

Dean finally looked at Cas and spoke. "So let's say this is real. What did you do to get yourself to get kicked out of Heaven?" Cas sighed and gestured for Dean to sit down. "This might take a while to explain."
