Bones Season 8 Quotes

Starling: Why'd she call you doctor?
Sweets: Because I'm a doctor. I'm a psychologist, a profiler.
Starling: You've gotta be kidding me. I'm working with a shrink.
Sweets: I'm more than just a shrink. The bureau gave me a gun. I should take the lead on questioning people. It's kind of my thing.
Starling: Just don't shoot me.
