The Leviathans

Fluorescent lights flicker in their cages, haunting shadows casted upon the brick walls and metal tables. The world seems to stop as the menacing words leave the beings lips, wildly wide eyes staring in amazement at the terror overtaking the hunters' features. With his fingers still wrapped tightly around the fabric of Dean's thick coat, Castiel tosses him across the room as if he were just a doll. His body crashes into a metal table, hard surface denting and tipping over from the sudden weight. With a groan, Dean crumbles to the ground in a pile of shattered glass.

"Dean!" Bobby's cry catches the attention of the insane looking Castiel, lips parting to reveal a soul-stirring smile as he takes long strides towards the older hunter. (y/n), in helpless desperation, is able to beat the angel to it, body protectively shielding Bobby's. This only seems to amuse the crazed angel

"Hello, little bird-" He teases her playfully, vicious intent lacing his cheerful tone ,"-how pretty your feathers must be! I can't wait to tear them from your human flesh"

"Fuck you" Her words are filled with venom, spitting out in his direction. He feigns hurt, bright eyes never blinking

"You wound me, Phoenix!" he chuckles darkly, watching as she continues to protect the frightened Bobby behind her ,"Is that any way to treat your family? Your elder?"

Without responding, she snatches his face in between her fingers, feeling the white hot heat from her palms grow in intensity as she holds his cheeks. Expecting his vessel to disintegrate from her touch, her eyes widen upon seeing her hand slowly sink into the skin. A black tar like substance seeping out from beneath the pads of her fingers as a faint sizzle echoes through the air.

"Sorry, little bird-" He wraps a tight hand around her wrist and snaps the bone in her arm. A scream tears at her throat at the pain erupting from the shattered limb

"Your fire doesn't work on little ol me"

Using his impossible strength, he throws her to the side. Her body slides across the ground until it crashes into Dean's, glass inserting itself into her soft flesh as she stops with a pained groan next to the man still somewhat out of it from his own fall. Slowly lifting her head up, she's able to watch helplessly as Castiel throws Bobby to the other side of the room, his much weaker body smashes into the brick wall with a sickening crack. He falls to the concrete lifelessly.

"Oh, this-" Dean and (y/n) watch as Castiel takes slow steps towards their broken bodies ,"-is going to be so much fun..."

Black veins begin to make a slow crawl across the length of the angel's neck, pulsating dangerously beneath his skin as he methodically paces the lab. Dean, glancing over to lifeless heap in the corner, calls hesitantly

"Bobby?"

He doesn't answer for too long of a second. Calling a second time, the man finally shifts on top of his pile of shattered glass. (y/n) can hear the shaking sigh of relief that escapes Dean's lips upon the sight. When Castiel gets too close for comfort though, he quickly tries to stall his time

"How many of you ass-clowns are in there?" he asks the Leviathans bitterly, bloodied hand reaching down to check on (y/n) still laying next to him. Staring up at the green eyed man, she reassures him through a nod. He focuses his attention back onto the powerful being in front of them.

"A hundred? More?" He asks again, not receiving a response the first time. When the creature stays silent, (y/n) finds her ears picking up the faint pitter of liquid. (e/c) eyes glancing down, she watches as the same black goo from earlier oozes down his fingers. Slowly returning her gaze up, she finds that the liquid is steadily pouring from every hole in his face, seeping out of his flesh at a dangerous rate.

"Your vessel is going to explode." (y/n) states the fact hesitantly, eyes never leaving the man slowly melting in front of her ,"It can't handle all of you, can it?"

"Wouldn't do anything too strenuous," Dean adds, desperate to get Castiel to leave them alone ,"In fact, I'd call it a day! Head on home, huh?"

"We'll be back-" the words come out gurgled, mouth overflowing with the thick black liquid ,"-for you."

Without saying another word, the vessel packed tightly with Leviathans turns towards the exit, dragging itself down the dimly lit hallway. The faint sloshing of his shoes through the black goo seeping out of his pores fills the tense air.

"Well-" Bobby sits up with a pained groan, eyeing the shadow of the man disappearing down the hall ,"-this is a new one..."

"We have to get Sam and get out of here-" (y/n) slowly stands from the ground, Dean rushing to help lift her aching body ,"-Castiel could change his mind"

Nodding in agreement, Dean motions for her to get Bobby before turning to rush down to the room Sam was last seen in. Dragging the man up to his feet and making sure he was okay enough to walk by himself, (y/n) and Bobby follow close after. Their anxious steps echo throughout the stone hallway, faces barely illuminated by the pale yellow lights hanging overhead.

"Sam?" Dean calls out for his brother, the group picking up their pace upon hearing labored breathing coming from around the corner. Sliding into the room, their concerned gazes fall upon the massive man they've been looking for, body trembling against the brick wall and completely unaware of their presence. He was out of it. Dean reaches forward and lightly grabs a hold of Sam's shoulder, flinching back when the man gasps to life before them.

"Woah, hey!" Dean moves his hand to rest on Sam's arm, staring hard into his light colored eyes as Sam frantically searches the room around him ,"Look at me, it's alright..."

"Dean?" His voice is fragile, face full of fear as if the people in front of him were going to disappear any second.

"It's me, Sammy..." Dean replies, concern evident on his features ,"We got to button this up, come on. Let's get out of here."

Holding onto his jacket, Dean begins to lead the frightened looking Sam towards the exit, Bobby and (y/n) following close behind the pair. Spotting an opened metal door, padlock laying in a shattered pile near the wall, the group make their way outside. The early morning light illuminates their forms, eyes squinting to shield themselves from the bright blue sky overhead.

"He left a trail-" (y/n) points down to the splotches of tar black liquid staining the dirt beneath their feet ,"-are we following him?"

"As much as I'd like to say no-" Bobby gives each person a nervous glance, nodding slowly ,"-we should see what the son of a bitch is up to"

Without another word, the group follows the crumbs left behind by the melting vessel, boots kicking up the soft dirt as they rush forward to try and catch up with him. (y/n)'s (e/c) eyes spot a figure near a fence in the distance, hand reaching out to rip away the thick chains keeping him out of the enclosed area.

"He's getting into the water!" she shouts the observation, hair standing on end at the sight of him slowly wading into the pool, body slowly being swallowed by the clear water. The group rushes to the bank of the lake, eyes watching helplessly as he welcomes the cool water with open arms before completely disappearing beneath the waves. A haunting moment of silence passes before (y/n) has to cover her mouth, stomach turning at the way the water bubbles up in the spot Castiel had just sunk into. The once clear liquid turned murky and black, spreading out across the entirety of the lack like roots on a tree, before fading back. The leviathan were free from their vessel.

"Damn it" Dean is the first to speak up, green eyes staring at a sign posted near the bank. Following his gaze, they all seem to freeze in shock. In bold red letters read the words 'Public Water Supply'.

"If they're in the pipes...they can get themselves anywhere" (y/n) shivers at the thought, recalling the countless nightmares she's had about the Leviathans, the things she was still trying to convince herself were real.

"Awesome" Sam replies bitterly, the others nodding in sarcastic agreement as they stare out onto the lake. (y/n), noticing movement to her side, turns to watch as Dean slowly bends down near the edge of the water. A sad look crosses her features as he picks up a sopping heap of clothing. The trench coat worn by the man the hunters grew to love and she never got to really know. A sorrowful silence falls upon the group as they watch Dean wrap up the clothing in his hands

"So-" there's a shielded vulnerability as he glances at the others ,"-he's gone?"

"Yeah...rest in peace...if that's even in the cards" Bobby replies sadly

"Dumb son of a bitch" theres a fragile anger in his words, face full of hurt as he stares down at the wet trench coat

"Well, he was friends with us, wasn't he? Can't get much dumber than that..." Bobby glances over at (y/n), a pitying smile pulling at his lips ,"No offence."

Smiling lightly in response, she steps towards Dean. Placing a soft hand on his bicep, tilting her head down to look him in the eyes, she silently offers a gentle comfort.

"We did everything we could here, okay? Let's go"

Nodding in understanding, he quickly tries to cover up the fact that he's hurting with the loud clearing of his throat. (y/n) can see the way he buries his feelings, tossing them in a pit to deal with some other time. Glancing over at the others worriedly, they all watch as he makes his way out of the fenced area, never once turning back to look at the lake that had just claimed his friend. Without questioning or checking on him, the group follows after, knowing that today was a loss packed full of consequences.
