[Sam's heartbeat quickens, and for a moment he's not sure what to say, what to do. He doesn't have Dean here to help him explain, and Cas is — Cas is out, and Cas would know how to explain it to himself, right? But it's just him, him and all of his gross sins, all of his mistakes and all the lives lost that weigh down on him. He's ashamed, honestly. Dean's left this place to go die by Lucifer's (Sam's) hand. Cas could do the same, any time, any day.

I said yes.
[You sure did, Lucifer says. Sam's fingers clutch at his knees until the skin pales.

Sam pushes Lucifer down, bowing until his bangs sweep and hide his shamed gaze.
Maybe this is a good thing, though. Maybe Castiel will smite him or something. Purge the town of him for a time... Maybe this is how he gets around promising Dean he'd keep trying. He could just... let Castiel handle him and Lucifer both. Sure, he'd failed getting rid of Sam Winchester plenty of times-

But he's not an angel, now is he?]
He won.
