CSI: NY, Season 6

Hawkes:
(bitingly) You may save my life in here, but you killed my sister. And there's no redemption for that. Not in my book, no matter how hard you try.

Reggie:
Don't you want to know what happened?

Hawkes:
My sister never had it easy. She got mixed up with drugs, met people like you. I can fill in the blanks, all right? Trust me, I see it all the time.

Reggie:
You're wrong, man. Maya was a good woman.

Hawkes:
(cynically) Yeah. A good drug addict.

Reggie:
No, man, she-she beat that. Maya was already clean when I met her. I wasn't, and she made the mistake of trying to help me.

Hawkes':
(surprised) She got clean?

Reggie:
Yeah. Listen, man... I was high at the time, right? And we got into a fight. You know I-I had no idea what was happening until it was over, man. I swear, I had no idea, and then I lied to the cops. I told them she got killed by some dealer she was trying to buy drugs from. After that, I was out of control. Took two more lives and ended up here. Man, not a day goes by I don't think about what I did.
