A/N: Hey guys, well here we go, the final chapter, I hope you like it, let me know.

Disclaimer: The usual, I don't own Supernatural blah blah.


Dean started in surprise as Kia drew in a sharp breath and her eyes opened, he moved forward to help her as she struggled to sit up, worry on her face.

"Hey, what is it?" Gently he took hold of Kia's arms, helping her to her feet and noting to himself that she no longer seemed to be suffering the effects of the toxin he had injected her with.

"It's Alyssa; she's killed again." Kia's voice trembled and she would not meet Dean's gaze.

"No surprise there, I should let Sam know, she's more dangerous than she was." He reached for his phone, only to find his wrist grasped by Kia.

"Dean, you don't understand; the person she's killed...it's Sam." Her eyes met his, a swirling mix of sorrow and fear. Dean shook his head.

"How do you know, how can you be sure?" His grip tightened on Kia's arm, red marks appearing on her pale skin. When she spoke her tone was urgent.

"A person's life has a specific feeling, it's like a fingerprint. I've felt Sam's before and believe me I know it was him." She watched as Dean's eyes clouded in anger.

"So you're only standing because my brother is dead?" His voice was harsh with anger and grief.

Kia winced as his grip tightened still further and it took her only a second to work things through in her mind before she spoke again.

"Dean, listen to me. I can save Sam, but you have to get me to him quickly."

"Fine." Without another word, Dean moved towards the door, maintaining his grip on Kia's arm and pulling her with him.

It did not take them long to near the apartment building where the twins lived: Dean's almost reckless driving had seen to that; and his angry silence could have been cut with a knife. As they pulled up outside the building Kia turned to Dean.

"Listen to me, if Alyssa is in there then don't let her touch you, don't even go near her." She moved to get out of the Impala and turned back to Dean again. "Oh and for goodness sake, don't shoot her."

Dean grunted in reply and got out of the car, tucking his gun into his jeans and pulling his jacket over the top of it before slamming the door and striding towards the building, Kia following behind.

They ran through the halls of the building, skidding to a halt as they reached the door of the twin's apartment. Dean moved a hand to his gun as Kia fumbled with the door, finally managing to open it and they pushed through the door way and into the apartment, stopping in horror at what they saw.

Sam lay near the couch, one arm stretched out at his side, the other laying across his body. His shirt was ripped open almost completely, his chest and stomach exposed. His face was pale and he showed no sign of life. Dean ran to Sam, skidding to a halt and falling to his knees beside his little brother.

"Sammy!" Although he already knew in his gut that what Kia had told him was true he still felt for a pulse in his brother's neck, fingers desperately searching for any sign of life.

"Move!" Kia knelt beside Dean, pushing him out of the way. Dean watched anxiously as she placed a hand on Sam's chest and heard her intake of breath as she allowed the life to flow back into his brother's body. His brow furrowed when Sam seemed to be showing no sign of improvement.

"Why is nothing happening?" His voice was harsh and his eyes darted accusingly in Kia's direction.

"I'm bringing him back to life; it's going to take a little time." Kia's tone was brusque and she did not look up at Dean.

After a few more minutes, Kia smiled and Dean saw the light flutter of a pulse in Sam's neck; his brother was alive, if barely.

Their smiles faded when the bedroom door opened and Alyssa stepped out, her dark eyes filled with rage.

"Oh no you don't." Her voice was an angry hiss.

Without warning, Alyssa ran across the room, her gaze fixed on Dean. As Alyssa launched herself over the top of Sam, Kia pushed Dean out of the way, taking the impact as her sister crashed into her. Dean landed hard on the wooden floor and heard the thud as the twins hit the floor together.

The girls rolled across the floor, each trying to gain advantage over the other. Alyssa, identifiable by both her dark red strap top and the wild look in her eyes, had succeeded in gaining the upper hand. Her fist was raised; preparing to deal her sister a vicious blow; Alyssa was unprepared when Kia's leg swung round, her knee connecting with her ribs and sending her into the wall.

Dean could only watch as Kia rolled on to her front and scrambled across the floor, reaching for Sam's inert body. She managed to grasp his hand and what little colour that had returned to her cheeks faded as she allowed her life to flow into Sam.

"Kia look out!" Dean shouted a warning as Alyssa dived once more at her sister, grasping her leg and pulling her away from Sam. Alyssa's eyes were almost crazed as she pushed her sister across the room and threw her into the punch bag.

As Dean watched he realised that Alyssa had gone completely insane, she no longer cared who she hurt, as long as she survived. He wished that there was something he could do to help Kia but he knew that if he got close then Alyssa would drain him too and there would be no chance that Kia could save both him and Sam.

Alyssa had pulled one of the knives from the wall and was brandishing it at Kia.

"We could have been fine, nothing would have happened if they hadn't got involved." Her voice was angry and almost sullen. Kia shook her head.

"No, Alyssa, it was going to happen anyway. The cravings have been getting worse and worse, you know that we were heading in the wrong direction. We have to stop..."

"NO!" Alyssa's angry cry cut Kia short. "I'm not going to let you save him, I can't."

She lunged at Kia and they crashed together once more. Dean heard a pained cry and watched, helpless as they collapsed to the floor. After a moment that seemed to last a lifetime, Kia struggled back along the floor, her shoulders shaking and her gaze fixed on her sister.

"I'm sorry, Alyssa...I'm so sorry..."

Dean was hesitant as he edged closer to the girls, when he was able to see past Kia he stopped.

Alyssa lay on her back, her breaths shuddering and punctuated by gasps of pain. Her eyes darted back and forth, unfocused and her hands clutched at the knife that was embedded in her stomach, blood soaking through her top and running onto the floor.

As he approached, Alyssa's gaze shifted and focused on Kia, her pain filled eyes desperate and pleading. One hand moved, reaching out for her sister, but Kia shifted further away, tears rolling down her cheeks, her arm moving across her stomach as she suffered with her sister. Dean reached out for Kia, carefully staying out of Alyssa's reach. Kia turned to him, allowing him to slip his arms under her body and gently lift her from the floor.

Kia clung to Dean as he carried her across the room and knelt down next to Sam, cradling the girl in his arms. He could hear her whimpers of pain and feel her shake with grief. Dean looked over at Alyssa, her face was ashen and a pool of blood was growing under her body. He knew that she would not last long and with her all hope of bringing Sam back from the brink of death where he still hung would be lost. He looked down in surprise when he felt Kia stir in his arms, she shifted, pushing herself out of his arms and turning to kneel next to Sam.

"What are you doing?" Dean's tone was unsure and he met her gaze as she looked up at him.

"What I promised." She reached out a hand, her fingers brushing Sam's skin.

"Kia, no." Alyssa's voice was filled with pain and she lifted her head weakly.

"I'm sorry, Alyssa. This has to end." Her voice was a whisper and a single tear rolled down her pale cheek. She took a deep, shuddering breath and placed her hand flat on Sam's chest, allowing her life to flow into Sam.

Dean watched as Sam's breathing grew stronger and Kia grew weaker. After a few moments Kia slumped forwards, her hand falling to the floor. Dean moved to see if she was alright, but at that moment, Sam's eyes opened and he struggled to prop himself up on his elbows, his expression confused as he attempted to work out what was going on.

"Dean? When did you get here? What happened..." His questions stopped short when he noticed Kia slumped beside him and saw Alyssa where she lay on the other side of the room.

Kia looked up and smiled, her smile turning into a grimace of pain. Sam scrambled to kneel beside her, and she did not resist as he encircled her in his arms and pulled her towards him. Dean saw tears forming in his little brother's eyes as he looked at the girl cradled in his arms.

"Hey." Sam tried to smile reassuringly as he spoke.

"Hey." Kia smiled briefly before a shuddering, pain filled breath overtook her. Sam stroked her hair and shook his head.

"You gave too much, you..."

"Shh." Kia cut him off. "Saved you didn't I? There are certainly worse ways to go."

"No, you're not going to die." Sam once again shook his head, a tear falling down his cheek, he followed Kia's gaze as she looked over to where Alyssa lay; her eyes closed and her chest barely moving.

"She only has moments left, Sam and when she goes..." Kia did not finish, her breaths were becoming shallower and more laboured as her body shut down with her sister's.

Dean watched as Kia smiled once more and her hand reached for Sam's, their fingers entwining. Her body shuddered and Dean could see that she was letting the last of the life remaining to her and her sister flow into Sam.

Alyssa went first, her head falling gently to one side and her face becoming peaceful. Kia slipped away a moment later, her final breath a gentle sigh before her dark eyes closed and her head fell against Sam's chest.

Dean felt tears in his own eyes as he watched his brother cradle Kia's body. After a few minutes, Dean moved and placed a hand on Sam's shoulder.

"Sammy, we gotta split, if we stay here there's gonna be questions and the answers won't be good." Although Sam was upset, he knew that Dean was right and nodded, gently laying Kia's body on the floor.

"What do we do, Dean?" His older brother did not reply as he considered his answer.

It was way past midnight when Dean drove the Impala into the secluded area he had found, far away from anything else and unlikely to be stumbled upon. The brothers piled up old pallets and other pieces of wood that they found before carefully removing the two wrapped bodies from the back of the Impala. They had debated whether to bring Alyssa as well as Kia, finally deciding that the twins should stay together, even in death.

They watched in silence as the pyre burned, the fire dancing in the dark night. Hours later, when the fire had gone, they salted what was left one final time and buried the ashes. After a few moments, Sam drew in a deep breath and turned to Dean.

"Let's go."

With a last look back at the grave they went back to the Impala and drove away, the wheels making clouds of dust as they headed back to the road.


The end. Hope you liked it.
