1 Hallelujah by Leonard Cohen

Castiel didn't know what prompted him to save the old guitar he saw on the side of the road at a yard sale but as soon as he did he knew it was something special. The strings were broken, easily replaced, the wood was scratched, easily repaired, but there was just something about the sad little instrument that screamed out for saving. He paid $3 for it and felt that he had gotten quite the bargain.

"You don't even play guitar Cas." Dean teased him as he lovingly worked to fill in the scratches in the wood.

"I can learn." Cas replied.

"What use does an angel have for a guitar?" Sam asked him but unlike Dean his comment didn't contain the teasing, he was genuinely curious.

"It just looked like it needed help." Cas shrugged. Dean and Sam exchanged a brother look and Dean rolled his eyes. Hell if the angel wanted a guitar then let him have a guitar.

Castiel had never fixed anything in his life, not with his own two hands. With Sam's suggestion on looking through YouTube for repair tutorials and instructional videos on how to play he would spend all his spare time learning. He fixed up the old broken acoustic and within a surprisingly short amount of time the boys were listening to him practice.

"He's a natural of course." Sam said one evening as the brothers shared a six pack watching Cas strum at his guitar.

"He's a freaking angel, of course he's a natural." Dean rolled his eyes. He was watching Cas closely. The angel had stripped off his trench and jacket and rolled up the sleeves of his dress shirt to strum the guitar. His eyes were glued to the computer screen and he had a little scrunch in his nose while he listened to the instructions. As soon as the instructor finished with a tip he'd look down at the guitar, place his fingers along the strings and try it. Dean thought it was absolutely adorable.

"Oh god." Sam rolled his eyes and took a drink of his beer.

"What?" Dean asked looking over at his brother.

"You've got that look." Sam bitch faced him.

"What look?" Dean asked confused. Cas strummed the start of Twinkle Twinkle Little Star in the background.

"The same look whenever you see someone attractive play an instrument. I swear dude you some have weird music fetish." Sam told him.

"Can it Sammy." Dean blushed but went back to watching Cas playing.

"Can't believe the stupid angel ditched us for music lessons again." Dean complained as him and Sam sat in a bar sharing nachos and beers.

"I can't believe he found someone willing to take him teach him in such short notice." Sam said.

"Its a freaking guitar, not some holy object. Why is he so obsessed?" Dean drank some more of his beer.

"Maybe he wants something to distract him. With all the shit we deal with a hobby would be nice." Sam suggested.

"Then why not take up a real hobby, like pool hustling or poker?"

"Why is this bothering you so much Dean? Are you actually jealous of a guitar?" Sam teased his brother.

"Again dude? Can you get off the 'Dean's in love with Cas' train for one night?" Dean shot him a glare.

"Nope, I'm shipping you two hard brother." Sam grinned when Dean glared at him harder.

Many beers later they returned to their room to find Cas on one of the beds with his sleeves rolled up and a look on concentration on his face. He was playing the guitar like an expert, each slide of his fingers and stroke of his hand careful and precise. But that wasn't what made Dean freeze in the doorway and had Sam running into his back. Cas was singing.

Baby I've been here before

I've seen this room and I've walked this floor, you know

I used to live alone before I knew you

And I've seen your flag on the marble arch

And love is not a victory march

Its a cold and its a broken Hallelujah

Hallelujah, Hallelujah, Hallelujah, Hallelujah

Cas stopped singing and looked up at the boys shyly. There was a flush to his cheeks but his blue eyes were sparkling.

"Dude, you were right." Dean breathed out quietly.

"About what?" Sam asked looking over his shoulder.

"I'm in love with Cas."
