Title: For The Greater Good

Rating: K, and I don't own a thing.

Note: Spoilers for 5x04. A little AU version of Dean and Lucifer's conversation. Why Sam said yes.


For The Greater Good

"You'd better kill me now, 'cause I swear to God if you don't I'll find a way to kill you."

Lucifer pauses and gives Dean a smile full of pity, he steps closer and shakes his head. "I can't kill you, Dean." He says quietly with a slight shrug of his shoulders.

Dean growls, frustration and anger mounting, "Don't give me that bullshit, you sonuvabitch. My brother might have fallen for your mind games but I'm not about to."

Lucifer sighs, his face pulled into a frown that looks so much like Sam's bitch-face that Dean bites the inside of his lip until it bleeds. "You don't understand, Dean. I didn't trick your brother – I didn't lie to him, he knew exactly what he was doing. I can't kill you because I quite literally cannot."

"What are you talking about?" Dean demands furiously, "Sam would never give his consent unless he was tricked into it!"

Smile firmly in place, Lucifer replies, "You were my number one target, Dean. As Michaels vessel you were my greatest threat, and Sam? Sam wasn't stupid. He knew that I would find you eventually, that you would never give Michael your consent willingly…that I would be able to eliminate you with a snap of my fingers, even in my weaker vessel."

Dean remains silent as he mulls over Lucifer's words, unable to speak when the fallen angel continues to say softly,

"…and I owed your little brother a favor. I was in his debt for freeing me from my prison."

"So what?" Dean growls, going stark white as it suddenly dawns on him, and he speaks at a dead whisper, "Sam made a deal?"

Clapping twice, Lucifer nods, "Sam thought it would be a win-win situation for you. He makes me promise to never harm you – mentally or physically, and that gives you the time you need to destroy me. He thought things were lost between the two of you, and no matter how hard he tried, he knew there was no other way to protect you from me. He was convinced that what he was doing was for the greater good, even if it meant eternity screaming in his own skin."

Feeling sick, Dean staggers backward, horror written all over his face. Oh god – Sam gave himself over to the freakin' devil so that I would have a shot at ganking him…oh god!

"No…no…" He mumbles to himself, jumping slightly when Lucifer is suddenly inches away from his face.

"But there was one thing Sam forgot, Dean. One thing that he hadn't counted on…one thing he thought for sure would never be an issue."

Dean can feel tears slipping down his face as Lucifer continues, his body trembling.

"Sam never doubted that you would be able to kill me – him, when the time came…and that is where he was wrong."

Dean blinks and Lucifer – Sammy – is gone. The last thing he is aware of is his future self groaning on the ground and Zachariah in front of him before he is sent tumbling through darkness.
