Six Feet Under, Season 5

[David is putting stitches on the corpse of Paul Duncan, a triple amputee Iraq war vet, in the embalming room.]

Paul Duncan:
You're gonna die, David. Just like Nate, just like your dad, just like everybody.

David:
I am aware of the reality of death. I work with it every day.

Paul Duncan:
You're scared. You're more scared now than you've ever been in your life. You thought you knew what fear was when Jake poured gas all over your head, but this? This simple, unavoidable fact that you're alive and alone and you'll be dead, gone.

David Stop it.

Paul Duncan:
You'll never see Keith after that, you'll never see your boys.

David:
Shut up!
