H-Hypothermia

Takes place during: Season 10

(Sam's P.O.V)

We'd been ambushed, A routine hunt turned into catastrophe when what we thought was 1 werewolf ended up being about 10.

It happened so quickly that neither Dean or I had a chance to escape, which is how we ended up locked in a freezer while a pack of hungry werewolves patrolled the building.

My whole body shivered uncontrollably as I curled into myself trying to keep warm.

Dean was busy screaming his head off, trying to pry the door open with no luck.

"COME ON, OPEN THIS DAMN DOOR!"

I knew this rage was most likely coming from the Mark of Cain, he's been sporting for a couple months now, However we'd been stuck in here for several hours at this point and Dean's constant screaming wasn't going to solve that.

"D-d-dean th-that's enough." I begin trying to stop my teeth from chattering.

"You got any better ideas?" Dean asked angrily as he sat down across from me.

"N-n-not at th-th-the mome-moment no."

"Sam you're shaking." Dean points out as his anger starts to fade.

I try to stop but I can't because my whole body is frozen, I can barely feel my fingers and toes and the only thing I have on is a flannel to keep me warm.

"Aren't y-you c-c-cold?" I ask wrapping my arms around myself tighter.

Dean seems to ponder this for a second before answering.

"Ever since I got this mark, I tend to run warm. I think it's protecting me from the cold."

"L-lucky you." I stammer rubbing my hands together in an attempt to feel my fingers.

"Here Sam take my flannel, you need it more than me."

I try to fight him on it but the extra warmth from his shirt is irresistible and I take it gratefully.

Unfortunately it's too tight around the arms so instead I use it as a blanket for my hands, which helps slightly.

"Thank's."

"Don't mention it."

I can see that Dean is fighting with himself, the Mark compelling him to do things he doesn't want to do, his fists are clenched at his sides and his face scrunched up.

He turns further away from me, clearly at a loss for how to escape this prison.

(Cas P.O.V)

"Hello, Dean, are you home, Sam?"

I checked both Dean's cluttered and Sam's impressively neat rooms, however both were empty.

I decided the logical next step would be to call Dean, since that was the human way of keeping in contact with someone.

Of course the cellular device still confused me greatly, and it took several tries before the desired ringing could be heard through the phone.

"Hey Cas, what's up?"

"Dean, where are you?"

"I'm doing well, how about you?"

I sighed realizing this was part of Dean's sarcasm he often resorted to when he didn't want to talk seriously.

"This is serious Dean, are you on a hunt right now?"

"Weeeell yes, but it's a very tame hunt, nothing the mark will get too crazy over."

I huffed out a breath of frustration already on my way to my own vehicle.

"I thought I said hunting was a bad idea right now, the mark is too powerful, it is going to consume you if you're not careful."

"Cas, can you cut me some slack okay, it's a werewolf we're after, not anything Sam and I can't handle."

"Dean, every kill you commit gives the mark more power, a werewolf is no different."

"Dammit Cas, I'm fine, okay lay off me."

The tone in his voice was of anger, clearly the mark was already taking a toll.

"Where are you right now?" I asked, already seated in my car ready to drive myself out to wherever Sam and Dean were.

"Montana, I think the town is called Hespeler, but it's fine. Cas don't even bother, Sam and I are 3 hours away, just stay at the bunker and we'll talk later."

"But Dean…"

The call ended, Dean had hung up on me.

I quickly pulled up the digital map on the cellular device, slowly typing in Hespeler, Montana.

The nearest route was 18 hours away, nearly 2 days of driving for them, but for me just under 19 hours since I of course didn't require the human bodily needs, such as sleep and food.

I started up the car, preparing for the 18 hours ahead, hopefully Dean was right, and maybe he was of course 1 werewolf wouldn't be too much trouble, but I could sense the Mark, and it was getting much worse than Dean ever let on.

Hopefully everything will be fine, I just had a bad feeling about this.

(Dean's P.O.V)

"Sam, your lips are turning blue!" I stammered just having noticed Sam's condition.

Sam looked at me weakly, his head lolled to the side.

He wasn't even shaking anymore, just completely still, breathing slowly.

That was a bad sign, how I had not noticed before.

I cursed myself, I was so focused so consumed in controlling my rage, thanks to this stupid mark, that I had neglected to even turn my eyes away from that door and towards Sam who was clearly suffering.

I quickly made my way over, fighting the urges the mark was sending me.

Sam was easy prey just one move and he's at our mercy.

Stop, I can't think like that, not with Sam, never with Sam.

I forced myself to wrap my arms lightly around Sam, not even letting myself apply too much pressure, worried that if I gave myself that opportunity, the mark would turn it into something deadlier.

Sam was freezing to the touch, even with my flannel it did little to cover his huge body.

"De, I can't feel my hands." Sam almost whispered the energy for speaking, simply taking all of his energy.

He's on the brink of death. I should just put him out of his misery.

NO I mentally screamed at myself pushing those thoughts away.

"It's okay Sammy, I'm gonna get us outta here, and then we'll have a fire at the bunker, some hot chocolate, get you some blankets."

Sam smiled weakly at me, but did not respond.

We stayed like that wrapped around each other for a long time, hours passed with very little conversation.

Mostly just me making sure Sam was still conscious by asking him questions he could answer easily, although with every hour my little brother grew weaker as the impulse to kill grew stronger.

God maybe if he wasn't so goddamn skinny he wouldn't be freezing to death like he is now.

That was one of the main things I had noticed since Sam cured me of being a demon, was just how underweight Sam was right now.

His weight always fluctuated but it was almost as bad as when he was going through the trials and I thought he was going to drop dead just from undernourishment.

The lack of meat on Sam's bones definitely didn't provide much insulation, and it was blatantly clear locked in this freezer that his body was just weaker than it had once been.

Suddenly the sound of commotion could be heard from outside the door, something more than just the usual banter that was sometimes loud enough to hear from inside this freezer room.

I jolted upright as the door to the cellar made a loud screeching sound, and even Sam stirred some to look up at the source of the commotion.

"De?"

"Sam stay back, it's alright I'll protect you." I began approaching the door.

I was maybe 5 feet from the door when it flew open, the scent of blood permeating the air, sending the mark into overdrive.

However it was Cas who appeared blade in hand, blood dripping from several spots over his body.

"Dean, Sam." Cas sighed in relief.

"Cas how…"

But before I could continue another werewolf appeared behind Cas, knife in hand, and it was now more than ever before that the Mark forced me forward demanding I take this opportunity.

I charged past Cas leaping onto the man, who seemed caught off guard.

My mind was so overwhelmed with the need to kill, that I grabbed at the knife, ripping it out of the man's hand and plunging deep into his neck, relishing in the carnage of blood that spewed from the wound.

Deep guttural choking sounds escaped his lips but I didn't stop, nothing could stop me right now as I swung the knife down on his neck and head over and over, making quick work in severing the entities from each other.

He was dead but that wasn't enough, I needed more. I jammed the knife down into the corpse's chest, clawing at his skin feeling the way it empowered me.

"DEAN."

I continued my hands coated in the thick syrupy liquid of this man's blood, before stabbing him again this time in the stomach.

"DEAN, STOP IT!"

What was that annoying incessant voice, couldn't it see how important the matter at hand was as I dove the knife back down slicing down on the arms this time.

"DEAN THAT'S ENOUGH!"

This time the voice was louder, loud enough to break through some semblance of my concentration, and force me to turn my head in the direction of the voice.

Cas was there carrying Sam, Sam who was unconscious and blue in the face.

My brother, how had I forgotten my brother.

"DEAN WE HAVE TO GET SAM HELP NOW!"

This time I had fully snapped out of the violent rage I had moments ago been consumed by.

My hands and clothes were soaked in blood, as the corpse I had just mutilated lay scattered around the area. Flecks of blood on my face, in my hair I was covered in the evidence of my poor self control.

"Heal him, Cas HEAL HIM!" I snapped angry at myself, why had this happened my brother was freezing to death and I didn't think twice before leaving him.

"I can't, the grace I have been using isn't mine, I don't have enough power left to heal your brother."

I followed Cas outside my mind moving a million miles a second.

I stayed back as Cas lowered Sam into his car wrapping his trench coat around my large brother.

"Is he.."

"He's not doing well, we have to raise his temperature, and fast."

"Right."

I quickly got in as Cas turned on the heater, warming up the car.

"The Impala has blankets and stuff inside."

Cas nodded and I quickly directed him the short distance to where my baby was parked.

I allowed Cas to bundle Sam up, scared of what I was capable of, and what I might do if given the chance to get close to my brother right now.

Although I did help Cas maneuver Sam into the back seat, wrapped in blankets and such, and soon his eyes were fluttering open on the drive to the nearest motel.

"De….what happened."

"Cas came to our rescue Sammy, you feeling any better?" I asked keeping my eyes on the road as Cas continued to drive.

"A little."

I sighed in relief, knowing that Sam would be okay.

However, I wasn't sure if I was gonna be okay, not with the way Cas kept looking over at me and not Sam.

It felt like I was the one he was more worried about, I guess I couldn't argue with that after what had happened.

I couldn't have been more sure that this hunt was going to be fine, I'd felt like everything was under control, turns out that couldn't have been farther from the truth.
