Dean and Sam were sitting around the bunker up to nothing as they were in a lull between hunts. Dead growled as he shifted in is chair unable to find a comfortable spot with his right leg held up by the chair, his ankle in a make-shift cast. Sam looked up over his book to check on his brother and he nearly screamed like a girl as he quickly stood up and put his book down.

"Hey Cas." Sam said with a small twitch of his lips, Dean nearly fell out of his chair as he quickly stood up and raised a brow at the angel's ruffled look.

"Dean, Sam I need your help." Cas said quickly with a desperate look.

"What-" Sam was cut off as Dean spoke,

"This isn't some angel war, is it Cas?" Dean asked as his brow furrowed,

"No Dean this is much worse Crowley has a fledgling of Gabriel's grace. We must move now!" Cas snapped quickly reaching forward to grab the brothers' shoulder as to fly away with them in tow. Dean grabbed Sam's shoulder and pulled them both back with his eyes wide.

"Wait, hold on. Fledgling? Gabriel? What the hell Cas, explain first!" Dean growled eyeing the angel Cas shook his shoulders and his head glaring at the floor.

"A fledgling is a young angel and it has a part of Gabriel's grace because god choose him as his father. I think there are others but Crowley does moth have them yet! We have to go now!" Cas yelled grabbing them both as the brothers looked at him with flabergasted looks.

They landed outside an old factory that seemed to have abandoned for years by the rusted gates, cloudy windows and overgrown lawn that had vines crawling up the sides of the building. Cas quickly turned to Dean and healed his ankle before Dean and Sam quickly re-adjusted themselves before turning to follow Cas as he stormed into the factory. The light was low as they walked down the hallway. Dean had his gun drawn, Sam had Ruby's knife, and Cas had his Angel Blade in his hand. They moved slowly clearing any room they came across. They all froze in unison as an ear piercing scream split the air, Dean shrank against the wall and watched the window. He glared at it as the scream stopped, Sam was giving him a questioning glance and Cas looking at the window dumbfounded.

"Cas... Shouldn't that window have broken from an angel's scream?" Dean asked remembering the first time Cas 'spoke' to him in the motel room.

"Yes it should have... But-" Cas was suddenly interrupted has some song, Dark Horse by Katy Perry Sam realized, started blarring from deep inside the factory. "We need to get moving," Cas snapped breaking out in a run towards the noise. The brothers turned to each other and shrugged before following. They burst through a pair of double doors after Cas and Dean arched a brow at the seen. Some teenage boy was tied to a chair bleeding, growling, and seeming to be quickly losing consciousness as his head bobbed up and down as if trying to stay awake. Holy fire was lit around him as well as a few sigils as if Crowley was afraid of him. His black shirt was ripped and blood ran down his torso around a silver half-heart necklace that layed on his chest.

"Castiel, how nice to see you. Now if you don't mind SHUT OFF YOUR DAMN SHITTY MUSIC!" Crowley screamed as a ring of Holy Fire was lit around Cas and he gave Crowley a blank stare,

"That isn't my music-" Cas began and as Dean and Sam were thrown against the wall by an invisible force. Crowley glared at the angel.

"It has to be yours, it can't be his!" he yelled pointing at the boy as the music quieted the lyrics fell softly but still strong as a gust of wind picked up.

*So you wanna play with magic - Boy you should know what you're fallin' for - Baby do you dare to do this - 'Cause I'm comin' at you like a dark horse*

The music stopred as the stanza ended, Dean couldn't help but chuckle as Crowley growled turning in a circle, "What's got your feathers ruffled Crowley?" He asked with a devilish smirk as Crowley stopped moving to glare at Dean. Sam quickly looked between the two but he kept his mouth shut.

"What ever this is you fool it isn't an angel! I have wards up to remove their power! And the only affect the ring of Holy fire has on that thing," Crowley yells pointing madly at the boy, "Is that it suppresses his powers completely." Crowley ranted, "There are no demons or other angels besides the good old angel of Thursday here! What ever these things are they some how fly under my radar and that shouldn't be possible because I am the king of HELL!" Crowley yells throwing his arms around like an angry Italian. Sam and Dean chuckle nervously at the notice of movement behind Crowley. They couldn't see quite who, no what, it was. Cas stayed dead silent as he seemed to been able to see what it was. But Crowley gave them a pointed glare before continuing yelling at them. "You idiots stop with your girlish giggle fits! That music was coming from somewhere and have I have no idea where! CAN'T YOU REALIZE THAT'S A BAD THING?!" Crowley yells but then freezes as he hears a voice begin to speak behind him,

"Haven't ya ever heard of a radio Crowley?" A young girls asks. She has average length brown hair the waves ever so slightly. Her eyes are a piercing blue that stares into the depths of Crowley's as he turns to stare at her; she smiled as she noticed the fear dancing in his eyes. She was wearing a pair of blue jeans and a black tanktop. The necklace seemed to catch Crowley's attention as he sputtered slightly starring at the other half heart the boy was wearing. But what eventually grabbed the demon's attention was the sight he took in of this earthly human girl(creature) was the black and white wings that protruded from her shoulders. The marginal coverts were a midnight black, the secondary and primary coverts were black with a white blotch that came from the shaft, and finally the secondaries and primaries were black with white tips. The wings were flared out in a aggressive manner, the span of them reaching about thirty feet from tip to tip. The girl quickly lost her smile as she growled, a primitive sound coming from the depths of her throat. She flared her wings as she straightened her posture.

"Who the bloody HELL do you think you are you pest?!" Crowley yelled raising an arm as though to attack. With a quick flick of her wrist Crowley was sent flying into the opposite wall. The metal barb that was deeply set in the wall cracked itself free and wrapped itself around Crowley's arms and torso. Dean and Sam gasped her strength but the didn't say anything. Cas watched the girl's every movement with a predator's intentive gaze. The girl quickly turned and with a quick movement of her hand going down the holy fire around the boy flicked out. The girl panted slightly as she quickly ran to his side and slightly touched the pure golden shackles that encased his wrists. Not more than a second latter the shackles fell off him and he slumped forward. Before he fell to the floor the girl grabbed him and gently laid him down on the floor. She laid her hand against his forward and she slowly took her hand away as she kneeled next to him watching him closely. She was panting and looking fatigued at this point. She almost jumped back as he gasped and quickly leaned up into a sitting position. She touched his cheek with the palm of her hand and he growled as the blood faded from his skin and all his skin healed. The blood faded from his blonde hair and the girl gave a small smile running her hand over it gently. He glanced at her and his eyes widened taking in the sight of her sweating and drooping wings as she breathed heavily.

"What the hell! Don't do anything else or you will pass out!" The boy snapped quickly standing and bring her up with him,

"You warned me not to do it, damn hypocrite..." he said shaking his head. "Come on lets go..." he said trying to drag her away from the angel, demon, and the two men. She pulled her self out of his grasp and shook her head she raised her hand to touch him, "No! Don't you dare!" but it was too late. She touched him and as he vanished ahem fell catching herself with her arms.

She glanced up at Crowley with a glare,

"What the HELL are you?!" he yelled and then he smiled like a snake, "Oh... You're running low on mojo aren't you... You gonna let you loose birdy? Or do I have to hang here all night? Either way I am going to trap you like the like bird you are, birdy. Why don't we do this the easy way? Birdy, its me or those three; and those three will kill you... Come on Birdy you know the right choice, just say yes..." Crowley said with a sickening smile plastered on his face. Dean gaped at him and Sam's jaw dropped. Dean glanced at Cas to notice his jaw locked and him glaring at Crowley. Dean furrowed his brow at him slightly confused. His attention was drawn to the girl as she moved raising her arm. "Oh Birdy-" Crowley began was cut off from the girl on the ground she barred her teeth at him.

"My answer is no, you black blood..." she said she slammed her hand down on the ground she flopped down on her torso, her wings stretched out on the floor life-lessly. The windows shattered destroying Crowley's wards and he screamed as the Holy Oil fire surrounding Cas dissipated. Dean and Sam were soundleasly freed and they landed on their feet gun and knife drawn as they run towards the wings girl. Cas moved quickly but not fast enough. Crowley chuckled as he suddenly disappeared, Cas growled and turned towards the brothers and the girl.

"She has a weak pulse..." Sam said as he equated next to her, his index and middle finger on her neck. He stood quickly looking around.

"You think he'll come back for her Cas?" Dean asked looking down at the girl.

"Dean I am positive he will... We must bring her to the bunker and protect her." Cas said seemingly to himself as Dean balked.

"Cas this is someone's kid, we take her that's kidnapping! We can't fo that-" Sam started just as startled at the suggestion as his brother.

"Crowley wanted to figure out what they are, she sent the boy away because he was the same thing she was. You saw what he did to try and make him talk, do you want him to do the same to her?" Cas asked in his gruff voice. "She just saved our lives we can at least for her to wake up before kicking her to the curb." Cas snapped bending over and picking the girl up and beginning to walk away. Dean and Sam glanced at another; Cas was acting way weird even for himself. They followed him quickly outside before he turned and spoke, "Grab me," he said, the brother's did quickly knowing he would be willing to ditch them.

They puffed as the landed in the bunker again, Cas yet again walking out towards a spare bed room without a word. Dean and Sam waited to hear a door open and shut before turning to another.

"Sam, what the HELL is up with him?" Dean whispered his hand wacking in the direction that Cas just went.

"I don't know Dean. Crowley said she wasn't an angel, or a demon. So god only knows... Cas is acting weird though... And that boy almost did look like Gabriel's vessel but I am not sure..." Sam said shaking his head before running a hand through his hair.

"Yeah... And that girl's eyes looked almost the same exact color as Cas'..." Dean said pinching his nose, missing the award look Sam gave him.

"Maybe you go talk to him Dean, that might be the only thing that gives us any reasonable answers." Sam says as he shrugs his shoulders before turning and walking.

"Why don't you go talk to him?" Dean grumbles, he did not whine, and Sam chuckled and continued walking as he replied.

"Because Dean, you two are the one who share a profound bound with another."Sam said before disappearing around a corner. Dean sighed before following Cas' trail.

"Hey, its me. Can I come in?" Dean asks after gently knocks on the door.

"Come in Dean," Cas says. The angle is leaning, well sort of, against the farthest wall from the bed that the girl is laying on. She is still unconscious but it looks like Cas used some of his angel mojo to clean up the room and the bed sheets. Cas is chewing on something, probably his tongue Dean guesses before he walks in the rest of the way shutting the door before walking to Cas' side. He looks at Cas and debates on speaking before he finally realizes he might as well.

"Cas did you have any idea that-" Cas cut him off with a tired growl.

"I had no idea what we were walking into Dean, I apologize." Cas says with a frown but still stares blankly starring at the girl. Dean sighs shaking his head. They both feel frazzled but with the new-comer it made it worse. "

"What... What is she Cas?" Dean asks quietly starting at the wings.

"I don't know Dean... That's one of the problems... Do you remember how I said I felt a fledgling with a part of Gabreil's grace?" Cas asks so quietly Dean isn't sure he heard him. He nods his head.

"Yeah I do Cas, why? Who's peice of grace does she have?" Dean asks studying the reaction. He arches his brow as he watches Cas slam him eyes shut tight.

"Dean... She has a peice of my grace..." Cas says quietly as Dean jaw drops as he stares at Cas with wonder in his eyes.
