In the preview clip below, released on the NCIS YouTube page on Dec. 24, actress Jeri Ryan makes her first appearance on the hit CBS show with a feisty attitude. Gibbs appears shocked when he discovers his two exes are friends and then becomes infuriated when he realizes he has no choice but to speak to them.

When Gibbs makes it clear that he doesn't want to associate with his ex-wife Rebecca, his other former spouse threatens that she will audit him for six months if he doesn't comply. The women then tell Gibbs they will meet him back at the NCIS office once he's done scoping out the crime scene where they unexpectedly approached him.
