A/N: Thanks to everyone for all of their support throughout this fic. Sadly, this is the last chapter. But, if you want me to continue with the sequel, please let me know. Anyway, Roxy and I decided to do this last part like the finale of the show. Therefore, at the end, it's kind of taken from season four's finale, Lucifer Rising. It's not verbatim, but it's close. Enjoy! And review and tell me if you want me to post the sequel!

CHAPTER SIXTEEN: THE BEGINNING TO THE END

"Dean?" Sam asked, his spirits rising. "Dean, are you really there?"

"Yeah," Dean answered, closing his eyes at how broken his baby brother sounded. "Now what do you want?"

Sam could tell Dean was mad. "Dean, I'm so sorry. Please...don't be mad at me." He closed his eyes as more tears fell. Slowly, he opened his closed fist, resting his palm on the cold iron door. "You're all the family I have left in this world. I need you. Help me, big brother. Please?"

"Sammy..." Dean started, fighting his tears. Figuring this was a private moment, Flare walked outside.

Sam sighed. "Tell me you're not mad," he begged. "Please. Tell me."

"I'm not mad, Sammy. I'm just worried about you."

"Dean...we have to stop Lilith," Sam suggested. "Let me out of here. Please? We can kill her together."

"I can't let you out, Sam. Not yet."

Sam sniffled. "Well, could you at least stay here and keep me company?"

"Sure, Sam." He sat on the floor, staying silent, his back pressed against the door.

Sam did the same, not knowing Dean was sitting that way; just out of instinct, trying to get closer to his brother. He threw his head back gently, resting it against the door as well. ""Keep talking to me, Dean. Just to let me know that you're still there." he felt a little more safe than he had earlier now that he had his big brother in the room with him. And now that he knew Dean wasn't mad at him.

At the sound of Sam's voice, Dean let his head fall back to lay on the door. "Flare looked broken up when she came to get me."

"It's because I'm not talking to her right now. I just wanted to see you."

"She's just worried about you, Sam. She loves you. You should cherish that."

Sam nodded. "I know." He took a deep, labored breath. "Dean, I need help."

"I'll help you, Sammy. But you have to help me help you." He closed his eyes. "Stop drinking blood."

"Dean..." Sam cried. "...let me out. I don't like it in here. Please?"

Noticing Sam neglected to answer his request, he knew Sam had other plans when he got out. "Sammy..."

Sam closed his eyes, letting the breath he had been holding out slowly. "That means you're not going to do it," he cried. "You're leaving me in here...alone." Sam shifted so that he was on his hands and knees, facing the door. He placed an open palm on the door. "Dean, please...open the door," he begged. There was no answer. He beat the door with his open hand, rising to his feet. "Dammit, Dean! Why are you doing this to me?! You promised to protect me! You said you'd never do anything to hurt me!"

Dean stood as though Sam could see him. "I am protecting you, Sam! From that bitch, Ruby!"

Sam chuckled. "Don't call her that, Dean. She's done nothing but be there for me. You were gone! And she was there! You left me all alone! And she was all I had! She took care of me!"

"By feeding you demon blood?! That's not taking care of you, Sam! That's killing you!"

"No, Dean, it's helping me. It's making me stronger."

"No, Sam, it's not. It's a drug."

Sam sighed. "Dean, let me out, please?"

"No, Sam!"

"Dean..." Sam started, sighing. "I know what you think. You think I'm a monster. A vampire. You want to end me, but you won't. Because I'm your brother. You think I'm evil. Disgusting. Tainted. That's why you have me locked in here like some kind of wild animal."

"Shut up, Sam. I'm trying to keep you safe," Dean said before walking upstairs.

Hearing Dean walking up the steps, Sam scrambled to his feet. "Dean! Dean, don't leave! You said you'd stay with me! Dean, come back!" He sank to the floor, crying. "Come back," he whispered.

Flare stood outside, trying to ignore the conversation going on between Sam and Dean, but the shouting made it almost impossible. Suddenly, Ruby walked up to Flare. "So, you and Dean are torturing Sam, now, huh?" She chuckled. "You little bitch."

"Get away from me, you scum sucking bitch," Flare shot back.

"Do you even know what you're doing to Sam right now?" Ruby yelled, furious. "You're killing him! He needs to be with me. He needs to have my blood. It's what keeps him sane!" She shook her head. "And you're helping to keep it from him." She chuckled, crossing her arms over her chest. "No wonder he has sex with me and not you. You don't love him. Not like he loves you. And that's probably why he keeps coming back to me."

Flare shook her head. "D-Demons lie! You're lying!"

Ruby smiled. "Ask him yourself."

Flare ran at Ruby, ramming into her. "I will kill you! If it's the last thing I do, I will kill you!"

Ruby pushed Flare off of her, causing Flare to fall on her backside. "If you loved Sam, you would get him out of that room," she spat before she turned and walked away.

Flare curled up into a ball and started to sob. "Abbey...I need you here with me. I feel so alone."

Suddenly, a figure appeared before Flare. "Hey, Flare. You look like Hell," the girl informed, walking closer to her. "Believe me, I would know."

"A-Abbey?" Flare whispered, slowly sitting up.

"Nope, sorry, Carrie. I'm here to help you."

"G-Get away," Flare warned, throwing her hand out in front of her to put distance between herself and Carrie.

"Keep your shorts on," Carrie said, taking a seat next to Flare. "I'm not going to hurt you." She looked up at Flare. "Tonight. Lilith is going to break the final seal. Sam is the only one who can stop her. You have to let him out. Save the world."

"Why should I trust you? You killed my sister."

"Because the world depends on it. Carrie looked into Flare's eyes. "But hey, maybe the world would be better off if Lucifer was walking amongst the people." With that, she disappeared.

"Maybe we should just let him out," Dean spoke. He was merely thinking aloud, but he got a response.

Bobby looked up at Dean. "You know the minute we do, he'll just go back to Ruby." He sighed. He sighed. "But it's up to you. You're his brother."

Dean stayed silent, thinking, as he stared out the window. This was so hard. He loved his brother, and he wanted to do what's best for him. However, at the same time, Dean didn't think Sam knew he had his best interests in mind. It hurt Dean to think Sam was under the impression that Dean was just trying to hurt him. That's the last thing he wanted to do.

"Well," Bobby asked, "what's it going to be, boy?"

Flare walked into the house again. "Sammy?"

"Flare?" Sam asked. "Dean won't let me out."

"If this is wrong, I'm sorry," Flare said to herself before she opened the safe room door.

Sam looked at Flare, standing. "You're letting me out?"

"Y-Yes."

Sam touched her shoulder. "You look scared."

"Dean is going to kill me."

"No, I won't let him. You're coming with me." Sam walked towards the back exit. "Come on." Once outside, Sam pulled out his cell phone and called Ruby. "I'm ready. I'm out. Meet me." He looked back at Flare. "Come on. It's time to finish this." Flare felt like this whole thing was wrong, but she loved Sam, so she followed him.

He met Ruby in by the warehouse. She was in her car. "Get in," she ordered. Sam climbed in the passenger seat, telling Flare to get in the back. Once they were in, Ruby sped away. Finally, she stopped. "Okay," she started, climbing out of the car. "this is about two miles from where Lilith is." She looked at Sam who had also climbed out of the car. "You know what you have to do." She walked back to the trunk and opened it, hauling out a girl who was kicking and screaming. "The demon in her is dormant. It went into hiding when it found out our plans for it." She threw her into Sam's arms, and he caught her, looking at Ruby. Ruby cut the girl's throat. "Drain her, Sammy."

Sam looked at the blood dripping from the wound. He covered the wound with his mouth, drinking deep until there was nothing left to drink. While he was doing this, he forgot that Flare was there; focused only on the blood he was getting.

I can't do this Flare thought as she turned her gaze away from Sam drinking more demon blood. Quietly, she opened the door and ran back to Bobby's house.

"Dammit!" Dean yelled, seeing that Sam was gone.

"What is it, Dean?" Bobby asked, walking down the stairs. When he saw Sam was gone, he sighed, shaking his head. "Dammit!" He grabbed his gun. "We have to go find him."

"Flare let him out!" Dean yelled matter-of-factly. "I'm going to kill her!"

Bobby shook his head. "Now, don't go doing anything stupid, boy. Right now, we need to find Sam."

Ruby smiled as Sam let the girl's body drop to the ground. He looked up at Ruby, his eyes having a slight darkness to them. "Where's Flare?" he asked.

"She ran off when you were drinking. But who cares?" She pressed her body closer to Sam's. "Let's go kill Lilith. You're ready."

Sam smiled, capturing Ruby's mouth in a hard kiss. He shoved her away once he was finished. "Drive," he ordered. Ruby listened, reaching their destination in minutes. They walked into the church, seeing Lilith.

"Dean!" Flare yelled, running into Bobby's house. "Dean!" He turned, pointing his gun at her. She threw her hands up. "I know where Sam is."

"Take me," he ordered.

"I can't. We'll never make it there in time. Have Castiel take you."

"Cas, I need some help down here!"

Castiel appeared, worried. "Dean, there's not much time. Lilith is the final seal, and Sam is about to break it! Go now!" He placed a hand on Dean's forehead, teleporting him to the church where Sam was.

Sam walked into the room Lilith was in, stopping inches from her. "I've been waiting a long time for this," he said, waiting for the right moment to strike.

Lilith turned, smirking. "I was wondering when you would show up. But, Sam, you're not strong enough to defeat me. Lucifer will walk."

Sam shot his hand out, concentrating on one thing and one thing only; killing Lilith.

Ruby turned to look at Dean as he appeared in the church. She smiled maliciously, throwing her hand out, closing the door so Dean couldn't get in.

Sam's eyes turned inky black as Lilith convulsed and glowed from the inside. He had done it. He killed Lilith.

"Sam!" Dean yelled, beating on the door that separated them, trying to get him to stop. "Sammy!"

Flare looked at Castiel. "I need to help them. Send me there."

"I cannot do that," Castiel answered.

"Castiel, please."

Castiel looked away, looking as though he was watching some distant movie on the floor. "It is too late," he whispered. He looked back up at her. "Lucifer is free."

Flare continued to sob as Castiel disappeared.

"You did it," Ruby breathed. "You broke the seal."

"What?" Sam asked. "No, I just killed Lilith."

"Lilith was the last seal. You brought him forth."

"No, I just killed Lilith. I stopped it!"

"And it is written that the first demon shall be the last seal," Ruby said fervently. 'And you bust her open. Now guess who's coming to dinner."

"Oh, my God," Sam whispered, almost inaudibly. He fell to his hands and knees, wishing now more than ever that his brother was with him.

"Guess again," Ruby said, delighted.

Sam thrust his hand forward, trying to exorcise Ruby, but failing miserably, instead falling to his knees again. She laughed. "Don't hurt yourself, Sammy. You're not strong enough right now." She cut her forearm, showing Sam the wound. "You want?" She smiled, covering the wound with her own mouth and drinking deep, making little moaning noises as she did.

"The blood," Sam realized. "You poisoned me!"

Ruby smiled at him, licking the blood off of her lips.

Sam barely noticed when the door opened and Dean walked through. Ruby however, did notice. She turned, looking at him. "You're too late," she declared.

"I don't care," Dean hissed. He pulled out the knife he and Sam had used to kill so many demons before Ruby, advancing on her. Once Sam realizes what Dean is doing, he stands, holding Ruby in place to insure she doesn't get away as Dean rams the knife into her abdomen, twisting it angrily. And just as Lilith had, she flickered from within, gasping. Sam let her go and he and Dean watched as she fell to the floor, dead.

Dean and Sam stared at each other for a few quiet moments before Sam broke. "I'm sorry," he cried, tears rapidly falling.

Dean looked at Sam, his hard expression softening a bit. He hated seeing Sam this way. Suddenly, a white light emerged from the perfectly patterned portal created by Lilith's blood. Dean grabbed Sam's jacket, ready to pull him away. "Sammy, let's go," he ordered.

Sam clutched Dean's arm, unable to look away from the brilliant white light. "Dean...he's coming."
