AN: I'm back with the final part after extreme writer's block. I was generally so stuck on what to write but I've managed to scrape up the last bit. Enjoy!

Dean stood there as Sam tackled him to the ground. Sam pressed one of his white, polished shoes on his chest to prevent him getting up. A malicious smile spread across Sam's face and his eyes gleamed.

"You should have listened to me Dean," He spoke and pressed his foot on Dean's chest harder making one of Dean's ribs crack under the weight. "This would have been so much easier for you and Sammy if you had just left me alone the first time I escaped."

"Lucifer," Dean uttered through clenched teeth. "Sammy will beat you just like he did last time."

"I don't think so," Lucifer snarled. "Besides, you haven't got your precious angel and uncle to help you this time."

Lucifer moved his foot up to Dean's throat and began to cut off the oxygen supply.

"Goodbye Dean," With one swift movement, Dean's neck cracked and he fell into a dark oblivion.

"Dean!" The yell erupted from the back of Sam's throat as he sat up in bed sweating profusely.

He ran a shaking hand through his hair and fumbled with the light switch for the lamp on his bedside table. His eyes looked at the clock and saw that it was almost five o'clock in the morning. Sam rubbed the sleep from his eyes and got to his feet on shaking legs. His mouth and throat were dry and he was in desperate need of a drink.

Sam stumbled out of his room and down the hall to the kitchen where he grabbed and glass from the cupboard and took a drink of water.

The memories of the dream were still fresh in his mind and sent a sharp pain through his head. He held the bridge of his nose as a way to stem the pain.

Sam heard a door open down the hallway and looked up to see Dean emerging from his bedroom looking tired and bedraggled. Dean rubbed his eyes and moved towards his younger brother.

"You okay, Sam?" He asked before yawning widely.

"Dean, I'm fine." Sam snapped. "Go back to bed."

"Cut the crap, Sammy." Dean said. "I heard you shout before and you look like you've just crawled out of the ground."

"Talking about stuff isn't going to make me feel any better." Sam said and sat down at the table with a fresh glass of water. "Lucifer is going to take me over and there is nothing we can do about it."

Suddenly, there was a knock at the door and Chuck burst in without waiting for anyone to open it for him.

"Sam, Dean, you need to get yourselves as far away from here as possible!" He said sprinting towards them.

"Why Chuck; what's wrong?" Dean asked walking towards the flustered prophet.

"It's Lucifer," Chuck replied and cast a sad look at the youngest Winchester who was still sat frozen in his seat. "He's almost here. I'm so sorry."

"Right, plan," Dean stated and pulled his brother to his feet before dragging him along the corridor towards their collection room. "Chuck, go and grab Cas and bring him here."

Chuck scampered off as Dean flicked the light on and pulled open the door to the dungeon shoving Sam inside.

"Help me with the angel wards," Dean ordered to Sam who stood staring at nothing. "Sam, snap out of it and help!"

Sam came out of his world and began to paint wards everywhere in sight. Chuck returned with Cas and they began to help as well.

"You do realise that Lucifer is one of the most powerful angels in the world and these sigils are probably meaningless to him?" Cas said and stared at the brothers.

"Thanks for the memo Cas," Dean snapped. "I am not letting that son of a bitch take my brother again. Not this time."

Cas was silenced and continued with his sigils.

"Dean," Sam's broken voice brought his brother to his side immediately. "I won't be able to fight him. I was hopped up on demon blood last time so – "

"Sam, stop," Dean said and put a hand on Sam's shoulder. "I've already lost you to that dick before and I won't do it again. If it's the last thing I'm going to do, I'm going to save you from him."

Sam looked at his brother with tears shining in his eyes before nodding and continuing painting the sigils.

"Chuck, how far away is the bastard?" Dean asked as he patted Sam on the back.

"I don't-"Chuck was cut by a large blast of wind.

The ground began to shake and a large voice echoed around the bunker.

"You will come out of your hiding place, Sam." Lucifer boomed. "I will make sure of that. Mark my words."

"Over my dead body you son of a bitch!" Dean yelled into the air.

"That can be arranged," Lucifer said before the bunker began to fill with thick, dark grey smoke.

The four men began coughing and choking on the smoke and began to hurry towards the door. Sam froze in fear when he saw flames just outside the door to the collection room threatening to make its way inside.

"Sam, come on!" Dean shouted for his brother as he, Cas and Chuck scurried out of the room past the flames.

Dean saw his brothers wide, fearful eyes staring at the flames. He knew how much Sam hated fire especially after Jess; and even more so after his trip to hell. He ran back towards Sam and grabbed his arm before pulling his unmoving brother out of the room. The boys fell to the floor as the smoke filled the lungs further. Their eyes watered but Dean spotted Cas and Chuck running up the stairs to the front door.

"Sammy," Dean choked and felt around the floor till he grasped Sam's hand. "We need to get out of here. Come on."

Sam and Dean started a commando crawl across the floor towards the stairs. Dean could hear Cas and Chuck shouting for him as he and Sam reached the stairs and began their ascent toward the front door. He pulled Sam to his feet and they ran up the stairs with the flames licking at their heels.

As soon as Sam and Dean stepped outside, they took a deep breath and coughed and spluttered in an attempt to get the ash and smoke out of their lungs. During the coughing fit, Sam was lifted to his feet by the scruff of his neck and was held there by three demons, one of which was Crowley.

"I'm so sorry Sam," Crowley whispered into Sam's ear.

Lucifer stepped out from the forest at the side of the road and walked towards Sam.

"I doubt Sam is in any condition to fight me right now," Lucifer told the demons who had a firm grip on the still choking Sam. "It's his brother I'm more worried about."

The demons dropped Sam to the floor and gripped Dean as the violent hunter got himself under control.

"Get away from my brother you spineless dick," Dean growled as Lucifer approached Sam and took his face in his hands.

"Hello again, Sam," Lucifer greeted the youngest hunted who was still trying to clear his airways. "I'm ready for you now."

Sam groaned and tried to move away without success.

"Say goodbye to your brother Sam," Lucifer smirked as Sam locked frightened eyes onto his brother who was still struggling against his captors.

Suddenly, a bright flash of white light shone around the boys almost blinding them. When the light died down, Dean spotted Sam slumped unconscious on the floor and Nick was gone.

Cas slowly moved towards Sam and shook his shoulder. Sam sat up and stared around him before grinning and getting gracefully to his feet.

"Release him," He ordered the demons. "I hardly think he would harm me knowing that his innocent little brother is still inside here screaming to be released."

Dean collapsed to his knees as the demons and his possessed little brother disappeared.

"No," Dean choked and stared at the spot where Sam was moments ago. "No!"

Dean sobbed on the ground outside the flaming bunker for at least the next hour. Cas wrapped his arms around him and Chuck awkwardly apologised before disappearing off into the night.

Dean's little brother was gone. The end was near.

The End

I'm so sorry. Please don't kill me for being an evil bitch that enjoys inflicting pain and angst upon my favourite characters. I hope you all enjoyed it and please give me reviews to let me know what you thought :D
