Diane's 3rd husband was shot at the drive through window of a fast food joint. Now her 2nd husband had a gunfight at the window. See more »


Diane gives her login and password to McGee by announcing it in front of the entire team in a bullpen location. Surely, as a federal agent working on identity theft cases, Diane would know that this is, at best, a bad idea. At worst, because it's access information to a federal mainframe, this might be a firing offense or indictable offense. See more »


Senior FBI Agent T.C. Fornell: [Referring to Diane] It's getting late - with Lambert on the loose, she should probably sleep at your house tonight. I'll talk to you later.
[Tries to leave quickly. Gibbs stops him]
Leroy Jethro Gibbs: Yeah, you're right. She shouldn't be alone. And since you married her last, I think that means your place.
Abby Sciuto: [Watching from the side,] This is gonna be good.

Funny Episode Or One of Them!
4 January 2013 | by (Seymour Tennessee) – See all my reviews

Really a funny episode where Gibbs & Fornell are with their ex-wife Diane now an IRS agent as she is now married to a DHS agent. And he is missing. Much to both men's dismay.

As you have to throw in Tim McGee in the mix. As the men are not fond of their ex-wife as they three have to work together. Diane has some disdain for Fornell but she is kind of fond for Gibbs.

While they continue to constantly bicker and argue on a professional and personal level. Really a funny episode out of the usual case of the week thing, not that we NCIS fans mind.

But still it is a change of pace to see all three, as the second "devil" episode title with Diane being the you know what. Really Diane hopefully will still become a recurring character and charm or annoy her two ex-husbands whenever she is on.

Really don't find her annoying anymore!
