Supernatural, Season 5

Lucifer as Sam :
Oh. Hello, Dean. Aren't you a surprise? You've come a long way to see this, haven't you?

Dean:
Well go ahead. Kill me.

Lucifer as Sam :
Kill you? Don't you think that would be a little... redundant? [Sighs] I'm sorry. It must be painful, speaking to me in this... shape. But it had to be your brother. It had to be. [Tries to touch Dean but Dean flinches back] You don't have to be afraid of me, Dean. What do you think I'm going to do?

Dean:
I don't know, maybe deep-fry the planet?

Lucifer as Sam :
Why? Why would I want to destroy this stunning thing? Beautiful, in a trillion different ways. The last perfect handiwork of God. You ever hear the story of how I fell from Grace?

Dean:
Oh, good God, you're not gonna tell me a bedtime story, are ya? My stomach's almost outta bile.

Lucifer as Sam :
You know why God cast me down? Because I loved Him. More than anything. And then God created... [smirks] you. The little... hairless apes. And then he asked all of us to bow down before you. To love you more than Him. And I said, "Father... I can't." I said, "These human beings are flawed. Murderous." And for that, God had Michael cast me into Hell. Now tell me, does the punishment fit the crime? Especially when I was right. Look what six billion of you have done to this thing. And how many of you blame me for it.

Dean:
[voice wavering] You're not fooling me, you know that? With this 'sympathy for the devil' crap. I know what you are.

Lucifer as Sam :
What am I?

Dean:
You're the same thing, only bigger. The same brand of cockroach I've been squashing my whole life. An ugly, evil, belly-to-the-ground supernatural piece of crap. The only difference between them and you, is the size of your ego.

Lucifer as Sam :
I like you, Dean. I get what the other angels see in you. Goodbye. We'll meet again soon.

Dean:
[voice harsh and hoarse] You better kill me now!

Lucifer as Sam :
Pardon?

Dean:
You better kill me now! Or I swear, I will find a way to kill you. And I won't stop-

Lucifer as Sam :
I know you won't. I know you won't say yes to Michael either, and I know you won't kill Sam. Whatever you do, you will always end up here. Whatever choices you make, whatever details you alter, we will always end up... here.

Dean:
[tears start falling freely]

Lucifer as Sam :
I win... So, I win.

Dean:
You're wrong.

Lucifer as Sam :
See you in five years, Dean.
