AN: Okay this story takes place after the Mark Of Cain incident but it's a little different. I don't own SPN or anyone there in, I just own Lara. Let's get started.

Death Isn't the End

Prologue

Blood dripped from her hands as she stood in the middle of the room, bodies laid scattered everywhere, demons and humans alike. Lara Winchester had gone demon, the Mark had claimed its host. Her eyes black as coal. "Lara! Stop!" Sam, her second eldest brother, stood blocking her exit. Lara looked at him with a deadly smirk, "But brother, it's so much fun." Sam aimed his gun at her, a Devil's Trap bullet in the chamber. "You can't shoot me, you won't," Lara scoffed.

"We don't want to, but we will." Dean, her eldest brother, said coming up behind her. Lara looked at the fourth person in the room, the one who hadn't said a word.

"What about you, Castiel?"

Castiel looked at her pained. "Lara you have to stop this." He said. Lara laughed a cold laugh, "You three won't kill me." Dean took a step towards Lara who anticipated the move and gave him a back kick to his sternum. Dean flew back and hit the wall with a groan. Taking the distraction as a gift, Sam charged Lara and tackled her. They fell to the ground in a heap, Sam's weapon sliding across the floor.

Lara punched Sam in the face as he tried to restrain her. "Cass! Help!" Sam hollered. Castiel ran over only to be thrown back by a burst of power. The Mark had made her a strong demon. Lara rolled them over, pinning Sam to the ground by the throat, and with her free hand she grabbed the First Blade from her waist band.

Sam watched his sister bring her hand back for the kill, and closed his eyes.

"Lara!" Dean's voice broke through the fear only to deepen the act…Only it never came.

Sam opened his eyes to see a silver blade coming through his sister's chest…The end of an Angelic Blade. Lara turned her head and looked at her attacker as if confused. Castiel caught her as she fell sideways, her once black eyes a shade of silver blue, the eyes he'd grown to love.

"C-Cass?"

"I'm here Lara, just hang on okay?" Castiel said with tears in his eyes.

Lara reached up and touched his cheek, "I knew you could do it…" Castiel grabbed her hand, "Hey, don't talk like that…You'll be okay." Lara looked at him and smiled. "No Cass, you'll be okay…" She said as her eyes slowly closed, her hand falling to the ground.

Lara Winchester died that day, but she wasn't the only one….
