[There it is. The disgust and anger and disappointment, ready to be served on a platter. It's the reason he'd hidden all of it in the first place, when Dean resurrected — he knew. And he knew Dean would feel it all over again here. Maybe there'd be punches involved again. Maybe there's not.

Sam turns away, doesn't look at Dean.

("You're destroying your relationship with him all over again?" Lucifer asks patiently, "Bold move, Sam. Now he'll just see a monster. Again. That's all he'll ever see with you, no matter what he says to the contrary.")

Sam utters angrily:]

Doesn't matter. I deserve it.

[But his fingers are shaking, and he digs them into his jeans to do something about it.]

I thought Ruby cared about me. She saved my life, gave me something to do when you were gone. And then you came back. [His head whips, and his desperate gaze lands on Dean finally.] After everything I tried to get you out — after demons wouldn't even cut deals with me, how was I supposed to know you'd come back to see that? To see me?

[He buries his head in his knees, palms pressing the back of his shaggy locks.

("Sam, be reasonable. There wasn't anything wrong with you.

You are p-e-r-f-e-c-t.")]

Dad was right. He was right about me. He knew what I was. Before anyone.

He just made the mistake of not handling it soon enough.
