Law & Order: Special Victims Unit, Season 19

Benson:
I feel so guilty about this.

Barba:
What did you do?

Benson:
I called you about this case.

Barba:
You know, when we first started working together, what was it, five years ago?

Benson:
Six.

Barba:
The world was an old movie. It was all black and white. And it was high noon. I was Gary Cooper. I was absolutely sure, absolutely, who were the good guys, who were the bad guys. And then you, you started to weasel your way into my world, and the black and white became different shades of gray. Don't. Don't say it. Before I knew it, there were blues and greens and yellows and reds. I'm you now, Liv. You opened my heart. And I thank you for it.

Benson:
And?

Barba:
I've got to move on.
