Most of the italics are flashbacks.

Sam pushes Lucifer into the chair opposite Chuck, giving the fallen archangel a dark look to keep him sitting there. The tall man sits on the nearby steps leading to the telescope, making himself smaller than he appears. "One of you is gonna have to, uh, go first. You know what? Lucifer, you agreed to have a sit down if God would show, so..."

Dean simply rolls his eyes, nodding to Chuck as he sits beside his brother. "And Chuck, you did say you'd talk."

"Him first." Lucifer forces out, crossing his arms as he leans back in the chair. "I'm the one who's owed an explanation."

Chuck lets out an aggravated little sigh, giving his second oldest son a long look as he says nothing.

Dean groans, shaking his head. "Okay, let's try 'I feel' statements. Doctor Phil." He says the last part to Sam, who shrugs in response. "Eh?"

"Ah, yeah. Of course." They shift awkwardly on the steps, going quiet as they stare at the old beings before them.

"I am… sorry?" Chuck starts, "that you feel that I betrayed you. That I acted without cause." Lucifer simply shakes his head. "I'm sorry that you can't see you gave me no choice." He turns to Sam and Dean. "I'm good."

"You heard that, right?" Lucifer asks, a scowl on his face.

"We all know that you are God, but maybe could you be a little less 'Lordly'?"

Chuck frowns, confused. "But I am… I am the Lord."

"Wow. There he goes." Lucifer rolls his eyes.

"I did what I had to do!" Broken feathers float slowly to the ground, falling listly through the air. "To create the world, I had to lock Amara away. And when the Mark corrupted you," blue-silver grace rots away, growing darker and darker by the day, "and I saw you posed a threat to humankind, I did the same with you."

"No, you betrayed me." "Father, please! Please help me!" The young archangel looks fearfully at the Mark on his scaly arm, curled up on the ground in front of his father's throne room. "You gave me the Mark to lock her away, and when it changed me… when it did what the Mark inevitably does... you threw me away." He shakes the bars, the cage barely trembling as he throws his weight against the grace made barrier again and again. Why? Why is he doing this?

"No, son. The Mark…" Chuck pauses, grey blue eyes falling to the floor. "You always cast a jaundiced glance at humans." "Don't step on that fish." The youngest archangel tells the small blue-eyed angel, causing Lucifer to scowl as he watches on. "Great plans for that fish." "The Mark didn't change you. It just made you more of what you already were."

"What I was, was your son." "Don't make me do this, Father. Don't make me put the brother I raised down like a dog." "Your child."

"Why should I put you first above all others?" He closes the eyes of the fallen archangel, tears falling into the ashes of his wings, though his weren't the only ones to mark the ashes. Lucifer's own tears had washed away the edges of one of the larger wings and Kali's had pressed down the ashes near his shoulder, her weight rumbling his clothes. He always had a soft spot for Gabriel.

"You have any idea what it's like to argue with your father when your father is God?" He turns to his father, another scowl (though darker) on his face. "You have to do this, Michael. It'll hurt, but it needs to be done." "Everything is a tautology with you. Everything is, 'Because I told you so.' Everything's, 'It had to be done.'"

Dean scoffs. "Pretty sure that's all fathers." Sam clears his throat in a warning but gets waved off.

Lucifer straightens up in his chair. "Okay, fine. Big picture, as God. You did what you had to do. But little picture? You sucked at being a dad."

"Okay, maybe I didn't handle everything perfectly. But tell me: could I have kept humankind safe with you on the board?" Lucifer narrows his eyes, saying nothing as he stares at the 'man' before him. "I know about your little bid to replace me with the angels. Okay, 'New God,' what would you have done about you?"

"That is not the point."

Sam coughs a bit. "I-I can't believe I'm actually about to say this, but… um. Lucifer is right." He quickly continues when Chuck turns to look at him. "All he wants is an apology, and you're too concerned about being right to give him one. But apologies aren't always about being right. Sometimes they're just about apologizing."

Dean nods along. "Yeah, and the great thing about apologies is you don't even have to mean 'em. Y'know, I lie and tell Sam I'm sorry all the time." Getting a look from the younger brother, he mutters a 'sorry' under his breath and brightens. "See? That's. Heh."

"Enough from the peanut gallery." Chuck waves his hand and the two brothers are deposited somewhere else in the bunker. "What? What would you have done?"

Lucifer shakes his head. "It doesn't matter. You are my father and you forsook me."

His head bows, grey blue eyes falling to the ground. "I did. I was supposed to love all creation equally. I wasn't supposed to have favorites. But you… You were mine." You were my brightest creation was left unsaid. "I gave you the Mark because I loved you the most, because I thought you were strong enough to bear it." As it is in heaven, so it must be on Earth. "And when I saw that I was wrong… When I watched my choice devour my most cherished son, I hated myself, and so I punished you. And I am so sorry."
