The bolded is Lucifer, and the italics is Sam.
Lucifer stands alone in the cemetery, fixing the leather jacket Sam refused to let go. He rolls his shoulders, flexing his wings to smooth out rumbled feathers as he waits for the other archangel. They're going to get worse if you keep on doing that. Lucifer brushes aside Sam's comment as he pushes the human soul deep down and into a section of his grace, the sound of wings coming from behind him causing Lucifer to turn, finding Michael in some random vessel standing there.
"It's good to see you, Michael." Are you really? Michael nods, squaring his shoulders as he straightens up.
"You too. It's been too long." He pauses, wings settling into a relaxed fighting stance. "Can you believe it's finally here?"
Lucifer shakes his head. "No. Not really."
"Are you ready?" Michael asks, giving the younger archangel a searching look.
"As I'll ever be." A sigh passes his lips as the stubborn soul he buried deep inside his grace squirms closer to the surface. "A part of me wishes we didn't have to do this.
"Yeah." Michael agrees, nodding. "Me too."
"Then why are we?" Are you really going to ask him that? Keep quiet, Sam.
"Oh, you know why! I have no choice, after what you did."
"What I did? What if it's not my fault?"
"What is that supposed to mean?" Yes, Luce, what is that supposed to mean? Luce?
"Think about it. Dad made everything." Blame Dean. He usually shortens long and/or unusual names. Who even uses 'and/or?' "Which means he made me who I am! God wanted the Devil."
Michael scoffs. I'd never thought I'd see an archangel with a stick so far up his ass do that. "So?"
"So why? And why make us fight? I just can't figure out the point."
"What's your point?"
"We're going to kill each other." A dark look crosses the younger archangel's face. "And for what? One of Dad's tests. And we don't even know the answer. We're brothers. Let's just walk off the chessboard."
"I'm sorry. I-I can't do that. I'm a good son, and I have my orders."
"But you don't have to follow them."
"What, you think I'm gonna rebel? Now? I'm not like you."
"Please, Michael…"
"You know, you haven't changed a bit, little brother. Always blaming everybody but yourself. We were together. We were happy. But you betrayed me – all of us – and you made our father leave."
"No one makes Dad do anything. He is doing this to us."
"You're a monster, Lucifer. And I have to kill you."
"If that's the way it's got to be... Then I'd like to see you try."
Sighing, Lucifer reluctantly starts to circle his older brother.
