[Lucifer's eyebrows raise at the insult, but seems more than content to leave it be. He would have been angry in Dean's shoes, too. Angry to be jerked around and used and manipulated, all because he loved his family a little too much.]

You know, Dean, despite everything — I don't particularly hate you. Not like I do all the other unpleasant human-shaped leeches, roaming the earth. In fact, I owe you... You may have come up short for Sam, but you never let me down.

I never would have been here if you didn't break the first seal; if you hadn't undervalued yourself, threw yourself away at the first opportunity to ensure my vessel's survival and picked up that blade—

Well. The devil wouldn't be here.

[He licks his teeth, blood still painting them.

The air is thick with a suffocating warmth, but Lucifer radiates cold; too hot on Dean's back, frigid cold on Dean's front.]

So, you know. That's why I decided to pay a little visit. While everyone loves to give Sam credit for starting an apocalypse — for freeing me... you're an unsung hero. It's a little unfair of me not to appreciate your hard work.
