A/N: This is my birthday present to you guys, I hope you like it. AU after 7X03. This was a challenge given to me in which I was to write a girl Cas but was to make it a sisterly relationship. Sorry no Destiel, but I do have another girl Cas story I'll be posting soon which is not a sisterly relationship, just a heads up. :)

Disclaimer: I do not own any of the characters in Supernatural.

Sam and Dean walked through the halls with Dean sneaking glances at Sam with a smirk present on his face.

"It's not funny Dean" Sam whined.

"Dude, you got mistaken for a chick." Dean chortled.

Oh it had been funny alright. The boys had gone to a bar to unwind after a long hunt. Dean had stated that it was one of his constitutional rights, after all wasn't one of them freedom of happiness? He knew a good drink made him happy. Sam being the party pooper that he was had said no.

"We could be doing something beneficial like research Dean." He reminded his older brother.

Dean looked at him like he had gone insane. "Come on Sam we ganked that fugly's ass."

Sam stared at his brother and gave a long suffering sigh. "Fine Dean"

Later that night he would come to regret that decision.

Arriving at the bar Dean had found a girl or rather she had found him. Giving a wave to his brother and a smile to the female beside him Dean had walked away.

Finding himself alone Sam had gone up to one of the stools and gotten himself a drink. No sooner had he finished his first drink than he had felt a breath at his ear and one of the cheesiest pickup lines.

"What's a beautiful babe like you doing here?"

Sam stiffened, seriously? Turning around he stared or rather glared at the poor unsuspecting man.

He looked to be one step away from falling face down in a drunken heap. Seeing Sam's face though he appeared to quickly sober up.

"You're a guy?" He asked incredulously.

Sam thought he heard a chuckle somewhere behind him.

The guy seemed really apologetic. "I'm sorry man but with the hair….I just….." Seeing Sam's annoyed expression he finished up quickly. "I gotta go"

This time Sam heard the laugh loud and clear.

Exactly like right now. Sam ignored his slightly immature brother.

Dean caught the look his brother gave him and snickered. "I told you it would happen someday Samantha."

Sam rolled his eyes. "Shut up Dean."

Dean was about to answer when he heard a noise in their room. Looking at Sam he motioned for him to be quiet.

Getting the hint Sam quickly shut up. With a great amount of trepidation Dean placed a hand on the door and turned the knob.

In the darkness of the room they could see a figure crouching down by one of the beds.

"Step away from the bed and come up with your hands up."

Sam stared at his brother. "Seriously Dean"

The figure in question stood up and turned around.

"Hello Dean"

Man if she wasn't hot. She was a girl of about nineteen maybe twenty years, no older than twenty two. She was about 5'5 with a slim, delicate figure with dark brown almost black hair that reached her shoulders. The most striking thing about her though, was her bright blue eyes.

Dean didn't know who she was and gave her an askance look.

"Dean?" The timid voice spoke up. The young woman sounded nervous and much panicked. Then again that was the natural reaction of many people when they were faced with a gun and a glare courtesy of Dean Winchester.

Dean narrowed his eyes. "Who are you?" He demanded eying the girl in front of him warily. Sam stood to the side awkwardly watching the exchange not knowing whether he should raise a gun too or calm the girl down.

"Dean you and Sam know who I am." She answered a bit disappointed and hurt. This piece of information made Sam perk up as he now looked more closely at their intruder.

Dean scoffed. "Look girl I have no idea who or what you are, but I sure as heck don't remember meeting you." He gave Sam a pointed look silently asking whether or not he had met the girl.

Sam was sure that there was something familiar about the girl but he couldn't quite place what it was. He felt like he somehow knew her but at the same time he knew he had never seen her.

Dean took his silence to mean that he didn't recognize her and turned back to give her an apprising look. Something about the girl felt familiar.

"Are you a demon?" He asked. "Or just our personal Julie?"

"I am not a demon and my name is not Julie" She answered eyebrows furrowed and head tilted to a side.

Shit. Dean recognized that look.

"Cas?"
