The Mentalist, Season 4

Wainwright:
You know that psychopathy test I gave Tibbs? I figured out why it didn't work. See, it's a rating scale based on observation, so the more time you spend with the subject the more accurately you can then observe their behavioral traits, and guess what I've been doing?

Jane:
[smiles] Oh, you haven't.

Wainwright:
Glibness and superficial charm. Check.

Jane:
You flatter me.

Wainwright:
Grandiose sense of self worth. You betcha. Cunning and manipulative. Poor behavior controls. Failure to accept responsibility for actions. So I cross-referenced all of my observations with your history as a thief and conartist and, uh, congratulations, Jane. According to the score you are a clinical psychopath.

Jane:
Wow. Well, that certainly explains a lot.

Wainwright:
Now I know what I'm dealing with, so I'll adjust accordingly.

Jane:
[smiles] As you should.
