The Mentalist, Season 5

Lisbon:
You're putting your trust in the mistress of a serial killer. She's playing you.

Jane:
Playing me? How?

Lisbon:
You're blind. You're involved with her, it's clouding your judgement.

Jane:
There's no involvement. I feel nothing for her.

Lisbon:
Now you're really lying! ...I will make this very simple. I will not be a part of this and neither will you if you want to remain on the team.

Jane:
An ultimatum? Someone is playing a little too much poker... I confess. I may have some feelings, but if I have crossed any lines it is not because I like her. I will do anything I can to get to Red John, but you have known that since the start.
