The location show on the GPS tracker as the crime lab is actually Las Vegas City Hall.

This episode marks the first appearance of Anita Gillette as Lily Flynn, Catherine's mother.

The actor who plays Adam Novac (Alan Rosenberg) is Marg Helgenberger's real-life husband.

Catherine: I went out after work. Is it a crime to want a little human contact?
Grissom: I guess that's why I don't go out.

Adam Novak: No way you were never married. Oh, let me guess. You were young, he seemed more mature than he really was, he swept you off your feet, and uh, he let you fall.
Catherine: Bruised, but not broken.

Adam Novak: If she's got her mother's looks, you're in trouble.
Catherine: If I don't get home soon, I will be in trouble.

Lily: (to Catherine) What did you do, walk into a door?

Gil: Did you hear the one about the cop and the monkey who walk into a bar?
Catherine: I'm not in the mood.
Gil: Neither was the monkey.

Gil: He hit you.
Catherine: No, it was an accident.

Lily: I was a working mother too, you know?
Catherine: There but for the grace of God...

Catherine's line is actually a reference back to the episode "Slaves of Las Vegas" where she says the following:
Catherine: All my mother ever told me was cash up front.

The title of this episode is deceptive on the surface. Fans automatically assume the episode will be about Catherine Willows and will involve her weeping. The latter proves to be false and the former is only partially accurate. Yes, Catherine is the focal point of the episode but the reality is that the episode is more about Grissom than Catherine. It is another study of the relationship between these characters. A comparison of how they approach the outside world.

The title is a reference to the Weeping Willow tree which is most often used to represent sadness, loss and grief. The willow tree is also known for its ability to bend and survive a storm. This aspect is referenced in the line spoken by Catherine regarding her marriage “Bruised, not broken.” In fact this allusion is perfect for this character. She is a survivor who maker her life work no matter what is thrown at her. In this episode it would be having her personal life exposed to all of those she works with.

This can be compared to Grissom who is unwilling to bend. He pusher her off when she tries to tell him about Novac. He then blames Catherine when he’s blindsided by the revelation. He’s judgmental and over-reactive. His determination to finger Novac is as strong as it was with Sam Braun in No More Bets. The only instance in this episode that he shows any compassion is when he states “He (Novac) hit you” in reference to the cut on Catherine’s face. It is as if the two of them are replaying a scene from their past that both thought would never happen again. Ironically Catherine is as intent on convicting Novac as Grissom is.
