Crumpled copied smiles

Pairing: Dean/Cas
Au: Dean and Sam gone dark
Plot: Sam and Dean destroy the world and Cas is the only one who is left but not for long.

STORY BEGIN!

     A loose sigh radiated throughout the dark shelter.
     Castiel, an angel of the lord.
     "Castiel?" A younger angel by the name Samandriel asked, "Castiel, why do you carry that knife?" The younger angel addressed the old hunting knife with sigils burned into it with caution.
     Castiel was an old legend, he was the oldest angel besides Lucifer who still sat in his cell and waited. Although he was a legend the stories of Castiel weren't as shiny as before. They were rusted and grimy, they were old.
     "It is a knife that was gifted to me by an old friend," The angel sighed rubbing a scratched in D. W. "It was gifted to me by death, of course."
     Samandriel furrowed his eyebrows. "Who did it belong to?" Samandriel's baby like face was captured by confusion and interest.
     Castiel inwardly groaned, he knew a time like this would come. A time when someone questioned his blade and challenged his past.
     Castiel closed his eyes trying to remember everything. Remember was not quite the right word, he wasn't remembering anything he knows what happened. He remembers what happened he's more, reminiscing.
     He remembers them like how he remembers the world being created, most likely because they were his world. He remembers the tall shaggy haired boy who was his older brother's vessel, and he remembers the shorter freckled boy who was his oldest brother's vessel.
      He remembers both of them like the back of his hand. He remembers their adventures as well. He recalls a lot of motels and bars before the bunker was discovered. He remembers a red haired girl who was like a little sister. He remembers the grief and loss especially.
     Castiel heaved a sigh but finally cleared his throat and spoke, "Sam and Dean Winchester. They gave me this knife." Almost as if the two boys were there, right there next to him again, the angel smiled.
     Samandriel however did not smile, he flinched in fear of the names. He flinched like the spoken words would take form and melt into the two brothers themselves, but they didn't. "Wait. You knew them? Personally?"
     "I knew all of them," Castiel murmured. "At least, I thought I did. Once. A long time ago."
      "What were they like?"
     Some crumpled copy of a smile crossed his face. "They were going to change the world," Castiel's eyes filled with tears as he told the younger angel about his two longed for best friends.
       Castiel scoffed, "and in a way they did." He casted his sad blue eyes to the world that played outside his window. He so pitifully begged that it was simply a trick of the eye, or a prank. That the fires and blood that was seen outside his window was merely a painting someone sketched onto the glass that separated war and peace.
     "Were they always such monsters?" Samandriel asked his eyes flicking back from the world outside to the older angel again.
     "No, but it's possible there's a little bit of monster in all of us."
     The sunshine haired boy smiled at the saying but didn't bother to reply. He was too timid to ruin the older angels memories with a swipe of a sharp tongue dishing out reality.
     At the moment the two angels were simply basking in a past life. They were laying in Sam and Dean Winchester's life before everything.
Castiel already knew everything there was to know about the past they watched. He knew all the stories, word for word and he knew all the rhymes. However he never got tired of it. And he never got over the chills and speed bumps he experienced when he listened to their voices again.
Their voices. The Dean and Sam he knew. The ones that were brothers. The ones that saved people and hunted the supernatural. The ones that were good.
It wasn't supposed to happen this way. It was never written by Metatron or even seen by Chuck. It was a hunting trip that got them, got them both. A Women In White case that was in Sioux Falls. Castiel went along with but neither of the three were prepared for the disaster that was about to strike.
Castiel still isn't sure what happened that night. A demon showed up, he knows that but what about after? He was banished by a sigil, the demon was smart. When he returned, there was blood everywhere, however no bodies lingered.
After months of searching for the two Winchesters a massacre struck Lawrence killing nearly 80% of the city. Soon after that buildings exploded and natural disasters swept the earth. The Croatoan virus infected the nations, backing all of humanity up into a corner, or at least what was left of it.
The angels were baffled. The world's own personal assassins were almost invisible, no one saw them coming and no one sees them leave.
The attacks kept coming. They didn't come for days at a time and sometimes years at a time. However when Heaven was attacked it marked the longest one.
Castiel should have known. He should have known who it was when all two bodies went missing despite the blood. He should have known when the first massacre struck Lawrence of all places. He should have realized it when their old house was burned to the ground and the neighborhood was the bloodiest. He should have known it was them. But he didn't.
The blue eyed angel searched for safety and comfort in his Heaven, the autistic man's eternal Tuesday. However when he reached his safe haven, it was no longer safe.
The man laid in a pool of his blood crying for help, as his kite was stuck in a tree. Fellow angel's wings scorched the grass, Samandriel being one of them. Two lone brothers sat on a bench sharpening bloodied knives on bones.
"Sam? Dean?" Castiel said with his strained voice.
Dean was the first one to speak, "Hey Cas." His voice brought comfort to Castiel, it sung to him to relax and drop his blade, but he fought it.
Sam pushed himself off the bench and sauntered over to the bleeding man. Intensity swamped the Heaven as Castiel waited for Sam to make his move. The youngest Winchester's voice came quiet, "His name is Raven," Sam drawled out smirking down at the crying man.
"I know."
Sam shrugged, he squatted down to the ground close to Raven's head. "We've been looking for you." Sam drew a line into Raven's skin making him whimper.
"I know," Castiel bit his tongue from anymore of an answer.
Dean got up from the bench but did not make a move to assist Sam in torture, instead he walked to Castiel. Blood stained Dean's skin as well as clothes, it made Castiel sick to his stomach.
Dean circled Castiel like a predator about to attack prey. Castiel didn't follow his gaze but watched Sam cut Raven with the knife. Castiel's stomach lurched when he realized what Sam was cutting into the man a bloodied S laid on the man's wrist and a half done W being worked on.
Cold fingers danced strokes onto Castiel's cheeks gaining his attention. When Castiel shuffled his feet so his back was to Raven's cries, he was met with Dean's face smirking. Dean cupped Castiel's face and softly rubbed his lips with his thumb.
"You know Castiel," Dean said as he pressed his body into Castiel's grabbing his left wrist. "I've always loved you."
"Don't say that to me. Don't you dare."
Dean cocked his head to the side acting clueless. He pouted mockingly, "Why Baby?" Dean leaned in towards Castiel, making sure the angel could feel his breath on his opened lips. "Are you afraid of the dark?"
Castiel only got a glimpse of Dean's eyes turning pitch black before rough lips were pushed onto his. On instinct Castiel closed his eyes. Castiel lost himself in the kiss but did not dare make a move to kiss back, frightened it would just give Dean more of a reason to not be cured.
A searing hot pain engulfed his stomach. Castiel tried to shove Dean back but the demon just kept pushing his lips onto Castiel, swallowing all of the angel's screams. Suddenly he went limp in Dean's arms, closing his eyes fearing for the worse.
Dean laid the angel on the floor but no scorch marks burned the grass. Instead blood did, the angel laid in a pool of the warm sticky substance, only half way subconsciously there.

Then black.

A voice greeted him in the darkness, a voice that smelled of old hidden comfort words. The voice sang, "Come on Baby, open your eyes." Obeying the voice Castiel opened his eyes, and black swamped the once ocean blue.

A demon arose. A demon that was once an angel of Thursday. A demon named Castiel, the very same demon that saved the world alongside two boys and an old drunk. But that Castiel is gone now, he was replaced by this one. The one that has D.W. cut into his skin to show he belonged to someone, not just anyone but

Dean Winchester.
