Prompt: Dean and Sam (not Wincest), Dean is actually Lucifer's vessel and Sam is Michael's
"Dean, son," he says, wearing Dad's face and talking with Dad's voice. "Just say yes. You can rest then, knowing your work is done." Dad's expression is earnest, his hand firm on Dean's shoulder. It's like he never left, never died in Dean's place, never laid such a burden on Dean's back. "Just say yes, Deano."
"I can't," Dean answers, looking up into Dad's eyes. "Michael will kill Sammy."
Dad's smile is gentle, sad. "I can promise you, Dean, Michael won't."
He blinks, at a loss. "What?" he asks, stepping back. "Aren't you Michael?"
Dad cocks his head to the side, smile stretching to a grin, self-satisfied and holding the winning hand. "Nope, kiddo, I'm not," he drawls, standing to his full height. "Wrong brother."
Dean backs up further, and he says, "Lucifer."
Dad smirks. "Yahtzee."
"What do you want with me?" Dean demands, going on the offensive. "Zachariah said--"
Dad's laughter booms out, like Dean can remember from before the fire. "That self-righteous ass?" he cackles. "He wouldn't know the truth if it slithered up and went for his jugular."
Stepping in close, Dad tells him softly, like its a secret meant for him alone, "Why do you think you spent time in my kingdom, Dean? Why Alistair chose you, favored you, taught and trained you? You were a master with that razor, awing even my grand inquisitor--no meatsuit for an angel could do that. Would do that. That's why your daddy wasn't the one." Dad's hand, calloused and warm, cups his cheek, while Dad's eyes stare into him, through him. "Your dad never broke, Dean, because Alistair didn't play with him like he did you. Johnny-boy got a nice warm part of the Pit and just sat there for a hundred years. And when the Gate opened, he left. Simple as that."
Dean tries pulling away, but Dad's grip tightens. "Listen to me, boyo," Lucifer whispers with Dad's voice, and Dad's breath is hot on his skin. "Listen to me, and listen well."
Dean closes his eyes, but Dad's fingers dig into his cheek so he opens them, looking at Satan straight-on.
"You will say yes to me," Lucifer promises him. He uses Dad's command tone, obey me, the one that Dean never failed to follow. "You will say yes and we'll have fun until God, my bastard father, looks back towards us and finally gives me the attention I deserve. Do you understand me, Dean?"
"No," Dean says. "I won't."
And now Lucifer smiles Dad's last smile, the heartbroken he gave Dean after he told Dean that terrible secret, right before he went to die.
"Yes, Dean," he says. "You will."
