Esterhaus, Bates and others in “Unfinished Business”

Esterhaus

You know, Fay, for as traumatic as these calls are, I wouldn't worry about the caller doing what he threatened to.

Bates

[nodding] It's true.

Esterhaus

Sick, lonely, cowardly types. They can't do anything but dial a phone.

Fay

[nodding, feeling reassured] I know.

Esterhaus

Of course, there was the Clausen case not long ago.

Fay

What's the Clausen case?

Bates

Sergeant...

Esterhaus

Uh, you don't want to know, Fay. She lived, though, and he was put away. [shakes her hand reassuringly] Nice seeing you, Fay. I'm sure you got nothing to worry about.
