Ok so here's the second half... I know it's short but it was a contest entry.
Thanks for reading!

Dean fell back onto the forest floor as the Shapeshifter released its grip, got up, and simply walked away; leaving him for dead as it once again vanished into the night. He lay still for a moment, staring up at the starry sky through bare tree tops, and feeling the warmth of his own blood as it trickled down from the wound. Knowing the longer he had to think about the knife sticking out of his gut, the worse it was going to be to deal with; Dean sucked in a shallow breath, wrapped his fingers around the handle of the blade, and yanked it out before he could give himself time to truly panic. The pain was instant and almost unbearable, but this was nothing new to him, living the life of a hunter, he'd been shot, stabbed, mauled and left for dead before...

Sam swore under his breath as he used the Impala's bright spotlight to pierce the darkness and look into the woods, his eyes searching for anything that moved. Now that the echo of gunshots had faded away in the night and he was left with only silence, he was starting to worry... His brother wasn't back yet. "DEAN!" He shouted, focusing the beam of light in the direction the other man had taken off, but knowing that he could be anywhere in those dark woods by now. Though he had tried to keep up, Dean had the head start and it didn't take long before the pair split up and lost sight of each other in the chase. He grabbed his cell phone and punched down Dean's number, taking a quick glance at the old factory behind him before once again turning his attention to the dark woods ahead, listening for the sound of the other man's cell ring. He didn't hear the phone, but what he did hear was his name, and that was good enough.

"DEAN!" He called out in response, leaning in through the Impala's window to lay a hand on the horn; hoping the sound would give his older brother the sense of direction needed to make his way through the dark maze of trees. When Dean suddenly stepped out of the woods, Sam couldn't help but breath a sight of relief. "Where the Hell have you been?"

"Out for a moonlit walk." Dean casually replied as he approached. "Where the Hell do you think?"

"Did you get it?" Sam continued. "Is it dead?"

"Yeah it's dead, no thanks to you..."

There was a moment of silence and Sam couldn't help but let his mind start to wander as he pocketed the cell phone he still held in his hand. If he had been able to hear the other man's voice drift through the night, then he should have been able to hear his phone ringing as well. Reaching into the back seat of the car to grab Dean's flask, he held it up for a moment before tossing it over to the other man; reaching for his gun as the Shapeshifter made a left handed catch. "Where's my brother." He growled, his tone of voice demanding an answer.

"Whoa, come on Sammy..."

"Unless you tell me where Dean is, I suggest you shut up." The young hunter snarled as he loaded his gun and turned the Impala's mounted spotlight to the impostor standing there in front of him.

Once the light hit it's eyes, the Shapeshifter knew that it was done for; it reached for the gun tucked in the back of its belt as Sam pulled the trigger on his. The single shot echoed in the night as the Shapeshifter fell dead to the ground and Sam lowered his gun, swearing under his breath as he did so.

Not only was it using Dean's form, it was also using his gun, which was something it couldn't physically replicate... That meant the thing had caught up to his older brother and managed to walk away with a weapon Dean never went anywhere without. A shiver crawled down his spine as he reached down to pry the gun from the Shifter's grip, tucking it away before turning towards the woods and taking in a deep breath.

With his flashlight in one hand and his cell phone in the other, Sam just started walking, trying to keep a straight line and follow the beam of the Impala's spotlight into the woods. He yelled out his brother's name, called dozens of times, but the only thing he could hear, was nothing but silence.

Dean knew his cell phone was ringing, but he too was busy applying pressure to his wound to pick it up. The only person that would be calling him anyway was Sam, and if that was the case, he was probably only using the sound of the ringing phone to narrow down his search. Sam would come looking for him, this he knew, but if the Shapeshifter was still out there, the last thing he wanted was to stay where the thing had left him. Setting his phone down at the base of a tree, he carefully pushed himself into a sitting position, wincing as he felt the pain radiate from his stomach. He swore to himself, the deep breath he took pulling at his battered body as he got to his feet and staggered out of the moonlight. He couldn't go another round with the Shapeshifter, he'd barely gotten by the first time and he wasn't literally or figuratively out of the woods just yet.

When Sam heard the faint sound of his brother's cell phone ring, he couldn't help but feel a weight lift from his shoulders. "DEAN!" He shouted, hearing his own voice echo through the woods but getting no reply. As he approached and the sound got louder, Sam knew he was getting close, but when his eyes caught the blue glow of a screen on the ground, his heart sank like a stone. He quickly made his way over, swearing under his breath as he reached down to grab the bloody phone from the forest floor. "Damn it..." He said out loud, using his flashlight to take a glance around him. "Dean?" He called out, momentarily focusing on what looked like a puddle of mud; though his mind was convinced it was blood he could see glistening in the moonlight.

Flashlight in hand, he carefully studied his surroundings, pausing as a wisp of smoke drifted out from behind a tree in front of him. "Dean?" He called out again, sure that what he was seeing wasn't smoke at all, but the warmth of his brother's breath hanging in the cool air.

Dean closed his eyes for a moment, his grip on the bloody knife tightening as he listened to the other man approach. He was trying to keep his cool, trying not to go into shock, but he knew what kind of situation he was in, and just knowing had his stomach in knots.

"Dude, it's me." Sam calmly started, pausing in his steps as he watched his older brother step out from behind a tree; clutching a bloody knife with one hand and his stomach with the other. He couldn't see much from where he was standing, but by the silver light of the moon, he could tell that his brother was hurt and exhausted.

"Sorry Sammy, but you're going to have to prove it to me..." Dean growled, holding the bloody knife out in front of him.

"Fair enough, we were chasing a Shifter." Sam was quick to reply, wasting no time pulling out his own silver blade and slicing into the palm of his hand. "There, convinced?" He asked, holding his hand out for the other man to see.

No sooner did he give his younger brother a nod, Sam was at his side, prying his hands away to get a better look at the stab wound. "Sammy are you alright?" He asked, sucking in a breath as the other man pressed his hands back against the wound to stop the bleeding.

Sam couldn't help but smile as he caught his older brother's eyes; the man was bleeding from the stomach and he could hardly keep his balance, but still he had to ask, just like he always did. "I'm fine." He was quick to reply, using his sleeve to wipe away a streak of blood that was running down the side of Dean's cheek. "You on the other hand... We need to get you to a hospital." He continued without missing a beat, hooking one arm around his brother's waist to help him move along. "C'mon, let's get you out of here."

"Did you get it?" Dean quietly asked. "Is it dead?"

"Yeah it's dead." Sam replied simply, helping the other man steady his steps as they started to make their way back to the Impala. "When I shot it, it looked like you... That thing sheds fast, is it safe to assume that it looked like me, when you came face to face with it?"

There was a moment of silence and Dean offered his brother a nod. "Yeah... and by the time I figured it out, it was too late... Son of a bitch landed a punch that sent me to the ground, next thing I knew it had my knife."

"Well it didn't fool me." Sam casually replied. "Thinking it could was its last mistake."

Dean couldn't help but smile as he spotted the Impala's bright spotlight in the distance, beaming into the woods like a lighthouse guiding them to safety. The nightmare was almost over, soon he'd be sitting in his car, on the way to some hospital in town where they'd fix him up and ask about the injury. He'd lie of course, tell them about a bar brawl he broke up, Sam would have a laugh, and then they would be off to their next hunt a few states over.

"Hey, you still good?" Sam asked, pulling the other man's attention away from his scattered thoughts. "You sound like you're out of breath."

"I'll live." Dean replied softly, a grin appearing to the corner of his lips as he caught his younger brother's eyes and let out a chuckle.

"What's so funny?" Sam couldn't help but ask, he too eyeing the Impala's bright spotlight beaming through the trees.

"Dude, you run like girl." Dean quietly remarked.

There was a moment of silence and Sam shook his head. "I do not. Jerk..."

"Yeah you do, Bitch."
