Ziva seems to have a good relationship with Ducky. When she comes back to NCIS with Tony and McGee, Ducky is the only one who has solid faith in her. In "Silver War", their friendship becomes more permanent when Ziva saves both of them from death at the hands of a murderer. Ducky is often seen sticking up for her when she has quarrels with Tony. She has also been seen going to him for advice and sharing a cup of tea with him. In Season 7, he persuaded her to briefly open up on the horrific series of events which led to her captivity in Somalia, culminating in her telling him that, "should keep [his distance her ... The ones who get too close always end up dead." Overall they value each other a lot.
