Author's Note: I have never had a writing block this bad in my life. Everything I tried to type I ended up deleting out of disgust. Nothing was satisfying my unhelpful muses and so it vanished. I don't think I've ever gotten this frustrated trying to write anything before. Not even school papers that bore me to tears….
Disclaimer: I do not own Supernatural. The creature is mine however.
Content: A protective and rather pissed off Dean Winchester, an ailing Castiel, a troubled Uriel and a rather enraged monster. Oh, and mustn't forget about the deaths…

Castiel gasped for air, his fingers going up to his heaving chest while his vessel's body shuddered uncontrollably and the angel could do nothing to stop it. The feeling terrified him; he'd never been unable to stop this body from doing something without his permission. He heard Dean call his name in confusion mixed with concern. The celestial being grabbed the comforter in an attempt to ride out whatever the hell his body was doing while managing to keep from face planting on the floor. A low whine sang from his vocal chords as he continued to spasm. The pain in his chest was horrendous, consuming every intelligent thought he tried to form. Dean's name escaped his lips as he felt his tedious grip on reality start to slip from his grasp. Black was forming along the edges of his vision and he fought against it with desperation. A searing pain shot through his true being when the old man took a bite from the heart and the angel groaned. His grip on the comforter tightened as he fought to keep his real voice from sounding.

Sweat soaked hair started to cling to his face but the angel couldn't bring himself to care as he tried to retreat deep into his grace. It felt wrong and a frown marred his lips as he searched through it, trying to find whatever it was that was causing this.

The next bite left him quivering and curled while whimpers snuck past clenched teeth. His back arched and the angel shut his eyes. A rough and yet gentle hand carefully placed itself on his shoulder in a comforting gesture and the angel leaned into it. He was terrified and hurting but he wasn't alone. He wasn't alone. A labored sigh rocked through him and he felt his body start to relax. The respite was brief though and then shear agony lavished its administrations as it raced through the nerves of his body. Castiel's back arched while he tried his best to fight the scream that sought to release itself from his true form. He failed to do so, the pain to strong and the sound escaped him without the slightest attempt to be silenced. The angel was dimly aware of Dean rocking away from him while uttering a string of curses.

The Ancient One apparently didn't like the sound either as he refrained from taking a nibble at the heart and his eyes scrunched tight. Blood leaked from his ears and the skinny fingers tightened in a result. The scream cut itself off as the angel gave into the darkness that beckoned to him; his body flopping down onto the mattress once more.

Dean lunged forward, his hands grabbing the celestial being's shoulder as the angel slumped back onto the bed. A venomous glare was cast in the direction of the elderly old man sitting on the far corner of the bed. It would have been almost comical had the old man not been holding a half-eaten heart in his gnarly hands. Disgust flickered through green eyes as he eyed the blood that oozed out from in between the ancient fingers, staining the fabric of the bed with intricate patterns. What concerned the hunter the most was the glowing tendrils of a light blue that snaked its way through the blood that occupied its time by dripping from the still beating organ. "So," he tried to muster up some sarcasm to lace into his voice but at the moment Dean Winchester was finding that hard to do. "You going to tell me how to waste your sorry ass?"

A baleful and slightly annoyed brown eye rolled in its socket before gazing over at the young hunter. "And why," there was another careful, slow bite, "would I deign to tell you such…" The croaky voice stopped once more to nibble at the heart, "important information?"

Dean stayed silent, the muscle in his jaw working furiously as he ignored the creature and focused his attention on Castiel. His fingers gently pressed against the angel's throat, feeling for a pulse that he knew wouldn't be there.

"You want to know something interesting?" The Ancient One asked, head tilting in a gruesome mockery of the angel when the celestial being was confused. "The heart keeps beating outside of my victims' bodies. Doesn't matter if I don't eat it for days, it still pumps and their bodies still act as if the heart is inside their miserable meat suits." Thin shoulders shrugged and the old man nibbled once more on the struggling heart.

For a brief moment it reminded Dean of a caged bird, desperately trying to spread its wings in order to flee from whatever horror was chasing it.

"Angel hearts are a rare delicacy my boy," The man hissed possessively.

"So what do you want? A fallen star in the form of a girl?" Dean snapped sarcastically, green eyes dark with broiling emotions.

"No Tristan, I don't." The creature surprised Dean by catching onto his reference. "And those witches were idiots." A look of distaste adorned the elderly man's face as if he'd just eaten something extremely bitter. "Every fool knows that you don't eat a star's heart. No, that author got it all wrong, you see, the angel's were trying to tell the bloody idiot that witches could eat angel hearts if the circumstances were correct." The last part was a snicker as the old chest puffed out with self-assigned authority. "Isn't that right Castiel?" A decrepit finger trailed its way over the angel's jaw line making the celestial being shudder and attempt to lean away from the touch. A strange look crossed the demon's face as he peered down at Castiel's chest. "Ah, you are a sneaky one." He muttered, clawed fingers trailing down to the exposed chest. He sensed more then saw Dean's hand move as though to swat him away and he snarled, a deep feral sound that would have sent most people scramming. But Dean Winchester was not like most people and the Ancient One resented that. This would be so much more fun if the Winchester was quaking where he sat with fear rather then anger.

"You can call me Darrel." The demon said as an after thought, "It was my vessel's name after all."

"I'd rather call you Dick." The reply was a harsh retort, ground out through gritted teeth.

"Dean…" The demon shook his finger at the hunter in a rebuking manner as though he was a school teacher that had caught the oldest Winchester decorating the school hallways with graffiti. "That wasn't very polite of you." The brown eyes feigned a hurt expression as they regarded the younger man coldly. "That could have hurt my feelings."

"Didn't know you had any." The retort was snappy as the green-eyed hunter carefully helped his friend to sit up. The angel obviously didn't like lying on his back with his chest and stomach so vulnerable to whatever it was Darrel wanted to do next. There was an intent expression of concentration on his face and Dean narrowed his eyes, trying to figure out what the celestial being was doing. "Cas?"

Blue eyes flickered up to meet his and Dean carefully moved the other being closer to himself in a protective manner. The angel leaned against him heavily, cheek resting on the hunter's shoulder as he curled up. Normally Dean would rather be torn apart by a Wendigo then to be caught 'snuggling' like this with anyone. He could make an exception for this though and so the hunter did, an arm wrapping around the seemingly frail body next to him. There was a soft whimper and Dean grimaced when he realized he'd been putting pressure on the celestial's shredded back. "Sorry Cas," he muttered quietly before his eyes flicked back up to watch the creature.

A movement from behind Darrel caught the hunter's attention and green eyes flicked to study the source of the motion. Uriel was slowly getting to his feet with a look of divine wrath adorning his already hard features.

Dean wasn't sure who he would rather face right now considering the options. He could go against Uriel seeing as he knew how to banish the bastard or he could try and go against a creature that claimed to be older then something known as an 'Eve'.

The soft tug on his shirt brought his attention back to the angel curled against his side and he frowned in confusion. Castiel was attempting to reach Dean's pocket knife, eyes gleaming with an unreadable emotion. What the hell? "Cas what…what are you doing?"

A grunt of effort was the angel's only reply before he managed to snag the handle with the tips of his fingers.

Dean swallowed thickly before he sighed and handed the blade to the angel, not wanting the celestial being to aggravate his injuries. There was a grateful flicker in the deep blue eyes before the angel slit his forearm carefully.

"Cas?"

The angel turned to look at him before forcing himself to sit up. A pained groan escaped the smooth lips of the celestial being as he twisted his torso so as to the see the headboard better. His fingers swept through the blood that his wrist was providing and started to draw.

The sigil appeared to be far more complex then anything Dean had ever seen before and the hunter watched with confusion. A low snarl snapped his attention back to the old man and his eyes widened. There were freaking spikes growing out of the old man's back while skin turned leathery. Red eyes flashed into place and Dean tried to pull Castiel away from whatever the fuck he was painting before he pulled Sammy up onto the bed. He wasn't very gentle about it and a flash of guilt ran through him but he couldn't afford to take his time.

The Darrel thing was freaking scary and Dean sure as hell didn't want to stay in the same area as it. Long silver claws extended from gnarly fingers and twisted nails.

When the transformation was complete the creature narrowed its eyes before howling furiously when it spied what Castiel was doing. The over-sized mutant-like body trembled with rage before it turned back to look at Uriel.

Blue light seemed to light the other angel up from the inside out and the celestial being was staring at himself in horror. The burly angel's lips parted as though to say something but before any words could form the angel exploded into flames. The flames were a rich emerald green as they devoured the angel. Dean was relieved to see that nothing else in the room seemed to be burning….

A whimper from next to him caused Dean to look over at Castiel and he was horrified to see that his friend was starting to glow in the same manner that Uriel had been. Pure unadulterated fear was shining in the angel's eyes as he frantically finished the sigil. Emerald flames started to form around the angel as Castiel added the last symbol to the series of sigils and the angel writhed as he tried to bring his palm up to the sigils. With a desperate lunge forward, Castiel managed to slam his palm against the largest of the sigils before he threw his head back and screamed in self-inflicted pain. The angel's body was rigid as he continued to hold his palm against the sigil.

Dean, the hunter was startled when he heard Castiel's voice inside of his head, close your eyes and make sure that Sam's eyes stay shut as well.

Cas? What….what are you doing? Dean attempted to ask mentally. It was odd to be talking inside his head like this and he wasn't even sure if the angel even heard him.

There was a long pause before his friend answered him and even then the usually powerful voice sounded extremely weak. I… I am going to drive the creature away. Dean… you must keep Sam from seeing Ruby. He mustn'- The angel's voice cut off completely and Dean reached for his friend mentally, searching to see if the celestial being was still present in his mind. The reassuring warmth was gone though and Dean fought the urge to panic. What had Cas meant when he said to keep Sam from seeing Ruby? The angel knew that Dean didn't approve of his little brother seeing the demon bitch anyways. He mustn't what?

A deafening roar sounded from somewhere to Dean's left and the hunter flinched reflexively before a shriek of pain made itself heard from where the angel was located next to him. A flash of bright light seemed to explode beside him and both sounds were abruptly cut off leaving a deafening silence behind.

The oldest of the Winchesters cautiously opened his green eyes, scanning the room before his heart rate picked up and he clenched his jaw. "Cas?" His voice was small and thick with a horrified grief as he stared at the empty spot next to him.

The spot that the angel had been occupying only a few seconds ago…

One could always point out that something was amiss when they were woken up by the roar of what sounded like a bear and a cougar combined. The strange yowling scream made the entire house tremble in the same manner that thunder sometimes could. Most people would be terrified and scared senseless but Bobby Singer was not like most people. He was not scared senseless, rather he was infuriated with being woken up from his well-earned sleep.

Bobby, shut your eyes.

"What the hell?" The hunter looked around when the weak voice whispered through his thoughts.

Shut your eyes, its for your own safety.

"Cas?" The hunter's eyes widened as he recognized the voice. Deciding that he'd best trust the angel, Bobby Singer closed his eyes and waited. A bright light suddenly illuminated his eye lids and then there was silence. Once the light vanished completely, Bobby grabbed his gun and quickly made his way up the stairs.

Bobby's senses were tingling and his muscles tensed before he entered the room where the boys had been and stopped in his tracks. A relieved sigh swept through him when he saw that Dean and Sam were ok, well pretty much ok. That wasn't what caught him off guard… The gruff utterance of , "Balls!" was heard as he followed the direction that Dean was gazing in.

Starting on the floor, a feather was imprinted followed by many more. The scorch mark traveled up the side of the bed and into the bed itself. Dean's t-shirt also had the scorched marks on it as the right wing had left its imprint in a similar manner.

Author's Note: So… Uriel is now dead and we've gotten a glimpse of the Ancient One's true form. Castiel is….shall we say… missing? There's a reason why Dean's skin doesn't have feather imprinted burns in it, same with Sam…. I hope you guys liked this chapter, I'm not really sure what to think of it quite yet so feedback is greatly appreciated!

Also, for those of you who are waiting for the second chapter of Fight It Cas, you can expect to see that within the next 7 days. Its going through the final stages of editing and fixing right now.
