Diane Desmond caused a heap of trouble for Vincent Savino on “Vegas” last week. As you’ll soon see, though, what happened in the previous episode may just be the tip of the iceberg.

In this clip from Tuesday’s (Dec. 18) episode, “Estinto” — which you can see exclusively on Zap2it — D.A. Reynolds (Michael Reilly Burke) tips off Vincent (Michael Chiklis) that Diane (guest star Ivana Milicevic) may be an FBI informant. How else, Reynolds wonders, could she have gotten drug charges against her to go away?

Needless to say, Vincent is less than excited to hear the news. “What do you think she’s doing in Vegas?” he asks. “Do the math,” Reynolds replies. “She’s here to get info — take you down.”

Incidentally, “estinto” is an Italian word that means “extinguished.” It’s usually used in music, meaning to play very, very quietly, but considering the context of this clip, it might have another meaning too. So watch your back, Diane.

The episode also will feature Dixon (Taylor Handley) going undercover at the Savoy after a series of robberies there, and Ralph (Dennis Quaid) and Jack (Jason O’Mara) looking into the mob when a contractor is murdered. “Vegas” airs at 10 p.m. ET Tuesday on CBS.
