Dean and Jo in “Unfinished Business”

Dean

So. Dangerous mission tomorrow. Guess it's time to eat, drink, and, you know, make merry.

Jo

Are you giving me the last night on Earth speech?

Dean

What?

Jo

What?

Dean

Jo

[leans in to kiss him, but breaks off] No. Sweetheart, if this is our last night on Earth, then I'm going to spend it with a little thing I call self-respect.
