Author's Note: This one's a little brutal. Sorry! I couldn't help it. I found myself wondering what might have happened if Dean didn't arrive in time — or at all — and this practically wrote itself. Please be advised… it does not have a happy ending. (Oh, and I don't know exactly where this scene takes place, but it made me think of St. Mary's Convent, so for the purposes of this fic, that's where it's set.) Enjoy!

Warning: Spoilers for episode 13x23, "Let the Good Times Roll."

"I love you. I love all of you."

"No! No, no, no, no!" Sam rushed forward, catching Jack as he crumpled. "Please… Jack, no…" They sank to the floor, Sam cradling the boy in his arms. This couldn't be happening. Jack had turned the blade on himself, but Sam felt the pain straight through his heart. "No… no…" His eyes filled with tears as he watched the color drain out of his friend's face. "You can't… Jack, please…"

But the damage had been done, and moments later the boy was gone.

Sam's breath caught in his throat. Please, not Jack…

He pictured his loved ones. Jessica on that ceiling. Charlie in that bathtub. Kevin on the bunker floor. Bobby in that hospital. Jo and Ellen in that hardware store. His mom, his dad…

Dean, torn apart by hell hounds.

Everyone he cared about… he could never save them.

Please, not Jack…

He shook his head, trembling in despair. How could he let this happen? "Jack…"

A chill spread through the room, covering the floor with frost. Sam wrapped his arms around Jack's body and glanced up at the source of the cold. Lucifer.

"Here we are again, Sammy…" He spoke in a soft, malevolent voice, eyes drifting around the sanctuary. "St. Mary's Convent, where it all began between us…" He chuckled mirthlessly. "I remember that night like it was yesterday. I was so full of hope. After all those centuries, I could finally walk free! Do you have any idea how grateful I was?" He sneered down at Sam. "I would've given you anything, you worthless pathetic runt. Anything. I never thought — never imagined — that it would all come to this."

Sam shrank back, averting his eyes. In that moment, he knew beyond the shadow of a doubt that Lucifer would never let him go. Jack died for nothing. But still, he didn't move. He couldn't. He couldn't leave the poor kid here, alone with the devil. Jack deserved better.

Without warning, Lucifer reached down and grabbed Sam viciously by the throat. His other hand seized the archangel blade and wrenched it from Jack's chest. Then, he straightened up, lifting the hunter off his feet. Sam gasped, dangling helplessly, clawing at Lucifer's fingers, unable to free himself.

"You took everything from me," Lucifer growled, striding over to the pristine altar. "You turned my own son against me." With his unholy strength, Lucifer heaved Sam onto the marble structure, slamming him down flat on his back. Sam's head hit the surface, stars exploding in his eyes. Lucifer took the blade and pressed it up against Sam's cheek. "If you thought I tortured you in the cage, you haven't seen anything yet. So brace yourself, Sammy, cause when I'm through with you, there won't be a scrap of humanity left."

Sam squirmed, unable to look away from the devil's crimson eyes.

The grip on his neck slackened… the hand brushed down his chest…

Sam panicked, bucking frantically… he tried to roll away, but it was too late. Lucifer plunged his arm in, reaching deep for his soul. Sam screamed, writhing in untold agony, while Lucifer leaned in close.

"Is it just me…? Or is it a little cold in here? What do you say we crank up the heat?"

Through the haze shrouding Sam's vision, he glimpsed the sanctuary catch on fire. They were going to burn.

Good… Maybe that would be the end of it.

"Oh, don't get your hopes up," Lucifer taunted. "This doesn't end till I say it ends."

With flames crackling around them, Lucifer maliciously fondled the innermost private particles of Sam's being. He showed no mercy… and no signs of stopping.
