CSI: Crime Scene Investigation, Season 2

Catherine:
You're racing me, Nick. We're driving the same car. (Nick keeps walking down the hallway) Nick! (he keeps walking) Nick, I'll have you removed from the case. You're confronting suspects before the evidence is processed. You're flying solo, cutting me out. What's going on?

Nick:
(takes a deep breath) Okay. There are some people you're supposed to be able to trust, you know? I was nine. And she was a last-minute baby-sitter. (Catherine's stunned) All I can remember doing afterwards is sitting in my room in the dark, staring at the door waiting for my mom to get home. But I've never told anyone before.

Catherine:
I'm sorry.

Nick:
It's what makes a person, I guess. I'm sorry, Catherine.
