<P> Season 6 focuses more on Ziva and Tony, but leaves their relationship undefined . Gibbs manages to have Ziva and McGee transferred back to the team in the premiere, but Tony is still acting as agent afloat on the USS Seahawk . In the following episode, Ziva accompanies Gibbs onto the Seahawk as part of a murder investigation and notices that Tony has pictures of her in a bikini pinned up in his room . After the investigation is closed, his deployment is ended prematurely and he is allowed to return to the team in the conclusion of the episode . </P> <P> As the season progresses, Ziva seems to have become involved with someone while in Israel but refuses to discuss it . In "Nine Lives", after she plans a visit to Israel, Tony looks through her desk and finds a picture of an unidentified man (Merik Tadros). Before she leaves, he tells her to have a good trip ("Nisiya Tova") in Hebrew, demonstrating that he had at least made some effort to learn that phrase . In "Cloak", Ziva disobeys Gibbs' orders to not engage during a war game, attacking the guards to defend Tony . Later they both say that they are "tired of pretending": Tony about the politics in the hunt for the mole within the team, which required the team to withhold information from each other, and Ziva for reasons undisclosed . </P> <P> Producers and writers for NCIS were initially divided over how to proceed with Tadros' character . In January 2009, some were suggesting possibly making him a relative of Ziva, an idea Cote de Pablo opposed . It was also proposed that Ziva would "stop toying with (Tony) completely" which would "drive him even more insane". De Pablo relayed, "We're going to play around with the idea that it could possibly be real love, and see how (he) deals with it ." In March, executive producer Shane Brennan stated, "You've got what you might want to call a triangle . It's a triangle with very, very pointy ends . Someone's going to get hurt ." He continued, "Something tragic will happen to Tony . Something tragic will happen to Ziva as well ." </P> <P> This comes to a head when Tadros appeared again portraying Mossad Officer Michael Rivkin in the "Legend" two - part, which also served as a backdoor pilot for the show's spin - off, NCIS: Los Angeles . He arrives in the United States during the NCIS team's hunt for members of a terrorist sleeper cell . Working independently, he draws ire from the agency when he kills suspects rather than bringing them in for questioning . Tony begins to doubt Ziva's loyalty to NCIS when she continues to defend Rivkin, and it becomes apparent by the end of Part II that she is involved in a relationship with him as the two are seen lying together in bed in the last few seconds of "Legend Part 2". </P>
