Criminal Minds, Season 6

Prentiss:
I knew you were watching me.

Doyle:
What's the expression? Keep your friends close, your enemies under surveillance.

Prentiss:

Doyle:
Seems hypocritical, seeing as I had to wait seven years.

Doyle:
Hello, Lauren. Oh wait, Lauren Reynolds died in a car accident, didn't she?

Prentiss:

Doyle:
You. Oh, not today, don't worry about that. But soon.

Prentiss:

(laughs) Well, that one does have some quirks.

Prentiss:
Come near my team, and I will end you.

Doyle:

Prentiss:
I was doing my job.

Tell me, Emily Prentiss, which do you think you are gonna be?
