Bones, Season 1

Booth:
You put a hit out on my partner?

Ortez:
She's not FBI.

Booth:
[punches him in the face, grabs him and points his gun right at his throat] I never said anything about FBI. She's my partner, see. And if anything happens to her, I will find you and I will kill you. I won't think twice. Come here, look in my eyes. [pushes barrel of the gun into his mouth and cocks it] Look at my face. If anything happens to her, I will kill you. This is between you and me, and nobody sees, nobody knows.
