9x07 Woulda, Coulda, Shoulda

Natalie Davis: I'm very sorry for what I did to Sara and to you. My foster father killed himself because of me. I was wrong to blame anybody else for it.
Gil Grissom: Is that how you really feel? Or is that how you think that you should feel?
Natalie Davis: I understand if you don't believe me. Psychopathic personalities are very often skilled at mimicking genuine emotion. But I'm truly sorry

DA Monroe: [DA Monroe is questioning Grissom about his motives for attending Natalie's transfer request trial] Then you are here for revenge?
Gil Grissom: I don't care about revenge. I have no stake in the outcome of these proceedings. Whether Natalie stays here or goes to prison is at the discretion of this court. I've been trying to believe that people can change, even people who are damaged. But I don't know if they can... [pauses] I just don't know.

Natalie Davis: [to Grissom] You're wrong about me. I really have changed. I have changed and I really do believe that people who do bad things need to be punished.
