A/N: I'm going to need a lot of fluffy stories and tons of Family Guy episodes after this. I can't believe I even finished it. (I can't believe I even wrote it...) I feel so evil and bad and...vicious for writing something so dark. I wanna bleach my brain now, please. -Shutters and hugs myself-

Disclaimer: I don't own the characters or the show. Just my mistakes.

A/N2: Okay, this is the last part for this story. I am done with angst and dark stuff. I can't do anymore. Not for a while. I'm finishing this now and with only three chapters because I feel like crying. Anyways, This is for my best friend Bekky, who asked for a dark dark angst Alpha/Omega Dean/Sam where Sam fights back because he doesn't really want Dean and Dean doesn't really give him a choice of the matter. This is it. Enjoy.

WARNING: Major Character Death. T_T

After Sam made sure to clean up and hide most of his bruises, he got dressed and met Dean downstairs. The Alpha male waited by the door with a kind smile, one that would have made Sam swoon had he not have met the real Dean behind the facade.

"Are you ready babe?" he asked. Sam had to put on a fake smile and nodded his head.

"Yeah, I'm ready,"

They left the house and decided to walk to where Sam had in mind. He wanted to find wherever his mate was and by the vibes he was getting they were somewhere in town. It had gotten dark by the time Sam had finished cleaning himself up so that gave him time to figure out a plan.

"Where are we going?" Dean asked, he had his hand on the lower area of Sam's back to keep him close. Sam could feel his heart beating in his chest; nervousness and anxiety over powering his will to run.

Sam sighed, his breath shaky, "I...I don't know just yet," the pull he was feeling got stronger and they weren't exactly in town just yet. When they walked out of the cemetery the pull was so nerve wracking that Sam fell to his knees and looked around but he didn't see anyone. It was dark and only one street light was one shining over the track that wrapped around the city park.

"Sam, are you okay?"

Sam trembled and wrapped his arms around himself as the pull on his heart and soul became almost too much. Was Dean really his mate? Everytime he got closer to him the pull got heavier and heavier on his heart. Sam felt the tears begin to fall down his face, he was seriously stuck in this hell. He wasn't going to get out and now it was comfirmed for sure that Dean really was his Mate.

Sam looked up to Dean and opened his mouth to speak when...

"Is there a problem here?" a strong Cajun accent was heard between the men. Dean stood up and looked behind him to see a tall man in black clothing and a black hat on his head. He didn't like the feeling he got from this guy. Sam stood as well, stumbling as he did, and when he spotted the man the pull on his heart expanded to him and it was like a current of electricity hit both of them. Sam knew. This guy was his true mate, not Dean. And then the feeling to sob happily was much needed but Sam help back. He still needed to take care of Dean.

"We're fine, thank you for asking," Dean said shortly.

"I can see those marks from here, what happened to him?" the man asked. Dean felt the need to protect hisself as well as Sam, but mostly himself, as he let his eyes change color and his teeth grow.

"That's none of your business what I do with my little bitch,"

Sam looked to Dean and saw his body begin to tremble. He glanced up in time to see the man smiled under his hat.

"I would appreciate it if you didn't talk badly about MY mate, you low life mutt," he sneered and bared his vampire fangs. Sam's eyes widen. He imprinted on a...vampire?

Dean dashed towards the man and swiped with his claws out, but missed as the guy dodged it and caught his hand. He twisted it, easily breaking the bones. Since Dean refused to phase he doesn't heal as quickly as he'd like. So screaming out in pain, the Alpha fell to his knees while the guy bent the hand back even further.

Sam stayed where he was and watched it all go down, not daring to move.

"Sam! You little slut, get over here and help your Alpha!" he screamed. The man snapped Dean's entire arm and tossed him to the ground.

"He's not anything to you anymore, he is an Alpha and judging by the way you're acting, you already know this," the man said. He looked up to Sam and give him a kind smile, one that Sam DID swoon over.

Dean sat up, holding his arm as he tried to stand but the guy was there in no time and grabbed him by his throat and lifted him up. "I saw what you did to my mate, I can see it through your eyes, in your mind. You're like an open book and I''m disguted by how foul you've acted,"

The man looked into Dean's red eyes, "He is my Alpha, you had your Omega. You've already imprinted. Ever since he died you've done nothing but hunt down weak men to try and over power then kill them later on if they got too much to try and handle. If I hadn't gotten here when i did, my Sammy probably wouldn't even be here right now."

Dean sneered and snapped at the man when he said 'My Sammy' and tried to grab at him with his free hand but wasn't successful. Sam watched the guy slam Dean into the ground and land earth shaking blow after blow to his face. He grabbed Dean by his shirt and tossed him against a near by oak tree, the sound of bones crunching against the force of the throw. Dean screamed out in pain as he laid there, his one arm bent and broken and now his back in the same shape. He let out a sob and looked to Sam, who looked back with a dull look in his eyes.

"Sam, baby, please help me," he whimpered. Sam took a step close to him and just stared, a completely straight look on his face. The vampire grabbed Dean by his hair and held him up so Sam could watch the ending.

He kept his eyes locked on Dean's as the guy shook Dean one time, with so much strength that it snapped his neck. He was still managing to breath so the man tossed him down and looked to Sam. "My names Benny,"

The taller man looked down with a slow blush and caught sight of Dean trying to crawl away. His entire body twisted and bent, no human would ever be able to survive it. Benny caught the look and was at Dean's side in an instant. He lifted his head, with one smooth swift motion, ripped Dean's throat out and feasted on his blood before letting the rest of it seep out of his body.

Both men stood, side by side, and watched as Dean choke on his blood. He looked around, trying to find help but not finding none then his eyes landed back on Sam. The new Alpha didn't look like he was remorseful in anyway, it broke Dean's heart. He opened his mouth but gagged on the blood before taking his last breath just as his green eyes faded.
