Nick: Hey, Grissom. You wanna talk to me?
Grissom: Yeah. Sit down. (pause) I heard that uh, Kelly Gordon may be a suspect in your murder case.
Grissom: Is that a problem?
Nick: No. No, it's not a problem. Hey, by the way I heard the tape. I did a voice comparison. Sylvia Mullins is the other voice on that tape. She's Walter Gordon's ex-business manager so I'm pretty sure she had something to do with my kidnapping.
Grissom: But now she's dead.
Grissom: So... it's over.
