In the Season 7 episode "Reunion", Gibbs confronts Ziva about Director Vance's allegation that she had been ordered by Mossad Director David to gain his trust by killing Ari. She admits that she had been under orders to kill Ari when it became clear that he was out of control, but elucidates that she had never intended to go through with it, believing him to be innocent. She further confides to Gibbs her feelings on the subject of Ari's death and her family: "I would have lied to you. He was my brother, and you were nothing. But I was wrong about Ari, and you ... Now he is gone. Eli is all but dead to me and the closest thing I have to a father is accusing me...". Ziva reveals that when she finally killed Ari, it was truly to save Gibbs and she was not following her orders, re-earning Gibbs' trust. In the seventh season episode "Good Cop, Bad Cop", the bodies aboard the "Damocles" are recovered and Mossad attempts to make Ziva the scapegoat for the death of Staff Sergeant Daniel Cryer, USMC, one of the passengers. After he persuades her to tell her version of the story and she is cleared, Gibbs whispers something to her and kisses her on the forehead, causing her to break down in tears of relief. Mark Harmon later disclosed that he had improvised the final moments of the scene, and when questioned about what Gibbs said, replied, "Pablo's not gonna tell you any more than I am—I don't think. That's our secret." Following investigation into Ziva's role in the events aboard the "Damocles", Director Vance approves an exonerated Ziva's application to join NCIS after initially rejecting it. Director Vance hands the approved application to Agent Gibbs, who in turn transmits it to Ziva, whom he calls "Probie".
