CSI: Crime Scene Investigation, Season 10

Sara (catching Lindsey looking at files on Catherine's desk):
Those files are confidental, Lindsey. You know that. You're lucky your mother didn't catch you.

Lindsey:
I'm sorry.

Sara:
Something wrong?

Lindsey:
Not really.

Sara:
Not really, what?

Lindsey:
It's just... It seems that Shawn had a really rough life. I was thinking that I could've been a little nicer to him. A couple days ago, he tried to talk to me.

(flashback)

Shawn:
Hey, Lindsey, you're mom is a cop or a CSI or something like that, right?

Lindsey:
So?

Shawn:
I was just curious, um, how does one go about accessing fingerprint databases?

Lindsey:
Why you wanna know if you're already in the system?

(end flashback)

Sara:
Why would Shawn be interested in fingerprints?

Lindsey:
He was hitting on me, obviously. I think he even had a little crush on me.
