CSI: Crime Scene Investigation, Season 7

[Sara finds Keppler in Grissom's office, looking at the miniature models]

Sara:
Hi. What are you doing?

Keppler:
Just looking.

Sara:
What do you think?

Keppler:
Meticulous. Obsessive. Clearly knows his way around a modeling kit.

Sara:
Grissom didn't make those.

Keppler:
No? Hmm. Fits the profile. Bugs in bottles, Darwin desk set.

Sara:
He's a... bit of a collector of certain things.

Keppler:
Yeah, I knew a guy in Philly like that. Kept a case of thumbs in his closet.

Sara:
Friend of yours?

Keppler:
No, serial killer.

Sara:
Do you miss it?

Keppler:
What?

Sara:
Philly.

Keppler:
No.
