It's evaluation time. This episode highlights the differences between how Catherine and Grissom approach requirements of the job. Grissom is naturally very linear and logical, while Catherine demonstrates that her job isn't her life.
Grissom: The goal of any supervisor is to teach someone to take his place some day.
Willows: Are you considering me?
Grissom: Why not? You’re certainly qualified.
Catherine: We're mid case. Why do we have to do this now?
Grissom: I have to get this evaluation in, or I'm gonna get written up
Catherine: Okay. My goals. Mm ... oh, all right, okay. [sits in front of Grissom's desk] For starters, I'd like two consecutive nights off. I would like to
cut my triples down to ten a year instead of the usual twenty, and, uh, I would love to find a reliable baby-sitter, so I could have myself some kind of a
personal life.
Grissom: You don't have a personal life?
Catherine: I ... write this down: I haven't had sex in six -- no -- seven months.
Grissom: [looks at Catherine and sighs] How can I help?[Catherine looks shocked]
Grissom: You. Advance, I mean.
