Gadreel and Sam in “Unfinished Business”

Gadreel

If this is like looking into a fun-house mirror for me, I cannot imagine what it is like for you.

Sam

[barely controlling his rage] How long have you been working for Metatron?

Gadreel

I will not talk, and you cannot make me.

Sam

Yeah?

Gadreel

I have been you, Sam Winchester. Your insides reek of shame and weakness.
