Okay so this is the fourth part! I read through the first 3 chapters and I saw that I'd made SO many mistakes! So I'm sorry about that and sorry if there are any mistakes! I'm so bad at describing the setting so I'm sorry about that too!

Thanks for reading –SikemiNatural

This is my curse

This is my curse (the wanting)
This is my curse (time)
This is my curse (the needing)
This is my curse

Sam continued to stare at the darker version of himself, a look of horror and disbelief on his face. That wasn't him; it looked like him but Sam was sure of it - that wasn't him.

"Oh come on Sam! You're in denial...you and me are the same" Dark Sam said with a bright smile, "Although I dress a lot better...but we don't need to worry about that" Sam shook his head frantically. No. NO. They weren't the same person. Dark Sam smile vanished,

"Your thoughts are hurting my brain Sammy...now listen to me. We are the same, get over it...oh and do you want to see my thoughts?" Dark Sam said, with an evil look on his face. Sam winced in pain as he saw an image of Dean lying on the ground dead. He didn't want to see this - Dean wasn't going to die.

"Stop, STOP IT NOW!" he yelled. Dark Sam laughed,

"Aww did poor little Sammy have a little nightmare?" he said in a sing song voice. Sam glared at him,

"Dean's not going to die...I...you've got to help me save him" he said in a shaky voice. Dark Sam rolled his eyes and flicked his fringe.

"I thought that you were brainy...gee how the hell did you get into law school? Why would I want to help you..?"

"Well...he's your brother too..." Dark Sam edged closer towards Sam his eyes filled with rage.

"You saw the vision right? You were the one holding the gun...but are you the one who killed him?" D.Sam said quietly. Sam frowned,

"What? I don't follow…what do you mean?"

"I'm the one who kills him! Okay?! Not you...you don't have the guts to do it!" D.Sam said with a look of disgust.

"I don't understand...why?"

"Uh, you're SO pathetic! Well let me tell you something Sam, I'm your curse, you're stuck with me and together we are going to follow our destiny" D.Sam said as he took another step towards Sam.

"But...why do we...I mean you, why do you need to kill Dean" Sam asked as he started to tremble. Dark Sam came even closer and Sam stumbled backwards and fell onto the ground. D.Sam shook his head and looked down at Sam,

"He's in the way, we could wait for him to die but that's too much of a risk. He needs to die. Tonight." he said. Sam remained silent as tears streamed down his face. D.Sam rolled his eyes,

"What's wrong with you?! You cry way too much...he's going to die anyway isn't he? We're just speeding things up...and then we can rule the world"

"Rule the world?" Sam asked. D.Sam smiled and his eyes turned black...like a demon's eyes.

"Together...we are going to become this! And we're halfway there..." he said as he motioned to himself.

"No way…won't I let you" Sam whispered.

"It's too late sunshine...let me show you something" and suddenly they were back in Wyoming. Sam was just about to kill Jake. They watched as Sam shot him four times, Sam flinched as he watched this scene. Dark Sam chuckled,

"This is my favourite part," he said, "He begged for mercy, but you still wasted him...well I did". Sam watched as he shot Jake three more times. He looked away guiltily. Well he'd deserved to die...hadn't he?" Dark Sam chuckled again,

"Of course he did" Sam however was still watching the scene intently; he watched himself wipe Jake's blood of his face. Then he saw the look that Dean had given him. Dean looked worried...scared even. Dark Sam watched Sam for a few moments and he said,

"This is getting boring..." and he clapped and they were back to the dark, empty place where they had been before.

"You're insane" Sam said in an angry tone.

"Well it has been said-"

"Shut up," Sam interrupted, "All you've done is talk and talk...just be quiet, okay. I don't need you or your emo crap...you're a monster and I'm going to kill you"

"Hey! Less of the 'emo' you were the one crying your eyes out! Besides, you're not going to kill me" D.Sam said with a smile.

"Oh yeah and why's that?"

"Because I'm part of you! You would be committing suicide...and like I said Sammy, I'm your curse" D.Sam stopped and he looked at Sam for a moment, "And some curses can't be broken".

Dean meanwhile was walking down the pathway that leads to the main road; there was no sign of Sam.

"Sam!" he called but there was no answer. Where the hell was his brother? Dean swore out loud, he had to find him. What if something had happened?

Sam sank down to the ground slowly; he couldn't take this anymore. He felt sick, things had been fine in the morning and then suddenly everything had changed. What was happening to him? He wasn't a monster. That 'monster' was a sick joke, he wasn't Sam. But Dark Sam had been inside him. Inside his soul; how did he explain that? He wished that Dean was here…he'd know what to do.

"You know what Sam? You're starting to get on my nerves, there's nothing Dean can do! You need to understand that" Sam looked up at Dark Sam and said,

"Screw. You", in an angry voice. Dark Sam merely laughed and said,

"Aww are you mad at me?"

"I hate you" was Sam's reply. He stared into the distance, why me? Why did the demon pick me? Why did he kill my mom? Why me?? I've destroyed my family…it's all my fault…Mom dying…Dad dying…and now Dean…all because of me. Maybe I should end it. Dark Sam's smirk was quickly replaced with a look of alarm.

"Excuse me?" he asked.

"Oh so you heard me then, well yeah maybe I should kill myself…it's the best option…"

"What?! Oh come on Sam…this is your destiny…our destiny! Stop trying to fight it" Dark Sam pleaded with a look of desperation in his face. Sam laughed dryly and said,

"Aww, what's the matter?" he said. Dark Sam glared at him,

"Fine, do what you want! I'm going to kill Dean whether you like it or not…try and stop me" Sam pulled out his gun from his pocket and he aimed it at Dark Sam's forehead. Dark Sam didn't even flinch.

"You're not going to use that" he said with a smirk. Sam's hand shook but he managed to steady it, "You still don't understand? I'm evil Sam and you're 'good' Sam. Evil Sam kills. Good Sam can't. You got that?" Sam's hand faltered slightly. He dropped the gun. He had no more fight left in him. Dark Sam grinned,

"No fight left in you? Dude the fight hasn't even begun" Sam looked up at Dark Sam – how did he know what he'd been thinking? And why couldn't he hear his thoughts. Sam closed his eyes and concentrated…he could hear a faint noise…it got louder and louder. He could now make out the words 'kill' and 'Dean'. Sam looked up and he saw that D.Sam still had that irritating smirk on his face. Sam remembered how dark Sam had messed with his head by showing him Dean's 'dead' body. He remembered the pain he'd felt; he need to get away. He had to distract the 'monster'. He decided to think of all the good things, things that made him happy. It seemed to do the trick; Dark Sam yelled out in pain. He grabbed his head and fell to the ground,

"Stop.Doing.That."He screamed, but the pathway had come into view. Sam took one last look at Dark Sam lying on the ground in pain. Then he turned and ran away. Dark Sam lay on the ground appeared to be unconscious. Sam meanwhile ran back in the direction of the motel. If he'd been five minutes earlier he would have spotted Dean walking in the direction that he'd just come from. He was walking towards Dark Sam and towards his death.
