Ziva David (pronounced dah-VEED) is a former Israeli Mossad officer and former NCIS Special Agent who was originally assigned to NCIS (agency) as a Liaison Officer for Mossad while also using her role to form something of a working relationship between both agencies.
She joined the team on a permanent basis after her predecessor, Caitlin Todd was killed in the line of duty by Ziva's half-brother, Ari Haswari although Leroy Jethro Gibbs was against her joining but he and the rest of the team later grew to accept Ziva's presence and as such, Ziva became a valued and respected member, a trait which lasted up until her resignation from NCIS and the Major Case Response Team.
In the aftermath of resigning from Mossad in the aftermath of being rescued from Somalia during Truth or Consequences (episode), Ziva eventually became an NCIS Special Agent which was revealed in the last few seconds of Good Cop, Bad Cop (episode).
Having served as a Probationary Agent since becoming an official agent at the end of Good Cop, Bad Cop (episode), Ziva became a fully-fledged NCIS Special Agent in the Season 9 premiere episode, Nature of the Beast (episode).
Like her colleagues, Anthony DiNozzo and Timothy McGee, Ziva resigned from NCIS to protect Gibbs in the Season 10 finale episode, Damned If You Do (episode) and as of the Season 11 premiere episode, Whiskey Tango Foxtrot (episode), Ziva remained a civilian and had also gone into hiding after discovering that she and her NCIS colleagues were being targeted by a group called the "Brotherhood of Doubt".
In Past, Present and Future (episode), Tony went to Israel where he eventually found Ziva and tried to persuade her to return to the United States but despite his best efforts, Ziva refused and opted to stay behind in Israel with NSA agent Eleanor Bishop later taking over the desk and position left vacant by Ziva's department from the team.
Ziva David was born on November 12, 1982 in Beer Sheva, Israel to Mossad Director/Deputy Director Eli David and his wife. She had an older half-brother, Ari Haswari, and a younger sister, Tali. Ziva served in the Israeli army for two years, as is compulsory for all Israeli women, and later joined the Mossad. She has said that no one from Mossad had recruited her — she volunteered. When Ziva joined Mossad isn't specified; however, Ziva was already a Mossad operative when her younger sister Tali was killed in a Hamas suicide bombing when Tali was sixteen years old.
NCIS Season 3
Ziva first appeared in the episode Kill Ari Part 1 (episode) when Mossad sent her to NCIS following the murder of Special Agent Caitlin Todd by Ari Haswari, who had gone rogue from Mossad. She got into a confrontation with Gibbs and stated that Ari was innocent, that he was still a member of Mossad and that he hadn't gone against Mossad nor was he responsible for Kate's death. She then secretly contacted Ari and promised to move him out of the country as well as promising to prove to Jenny that Ari was innocent while Ziva also told Ari that Gibbs was a man with blood in his eyes.
In Kill Ari Part 2 (episode), Ziva took matters into her own hands and attempted to move Ari out of the United States, presumably to protect him from Gibbs who was seeking revenge for Kate's death, even employing a courier to do but Tony witnessed everything and later informed Gibbs of the development. However, when she was later confronted with the damning evidence, she finally realized the truth and was personally responsible for killing Ari, saving Gibbs's life in the process while also revealing that Ari was her half-brother.
During a talk with Jenny, Gibbs revealed that Ziva was in the process of escorting Ari's body to Tel Aviv.
Ziva returned in Silver War (episode) where she revealed that she had become the Mossad/NCIS Liaison Officer, a move that left Gibbs and the whole team completely confused.
It was later revealed that Jenny had created the position and that she had assigned Ziva, believing that Ziva could learn from Gibbs although Gibbs was fiercely against the idea. However, Ziva later proved her loyalty when she saved herself and Ducky from a doctor who was attempting to kill them and as such, officially became DiNozzo's third partner while finally gaining the right to claim the locker and desk that had originally belonged to Kate as her own.
NCIS Season 4
NCIS Season 5
In the Season 5 finale episode, Judgment Day Part 1 (episode), Ziva was assigned to be part of Jenny's protection detail with Tony but after Jenny gave them the day off to go investigate the circumstances surrounding a former NCIS Agent's death, Ziva grew increasingly concerned and later convinced Tony to go searching for Jenny which they did. They soon ended up at a diner where they soon discovered Jenny's body among the numerous assassins that had been sent to kill Jenny herself with the grim discovery leaving both Tony and Ziva guilt-ridden and completely devastated over their failure to protect Jenny.
In Judgment Day Part 2 (episode), Ziva along with the rest of the NCIS team investigated Jenny's death. After the case ended, Ziva's liaison position was terminated under the orders of newly appointed Director Leon Vance who told her that she was also returning to Israel which left Ziva and the team stunned.
NCIS Season 6
In the Season 6 premiere episode, Last Man Standing (episode), Ziva temporarily rejoined Mossad and was seen singing undercover at a Moroccan bar. She got caught in an explosion but later survived and at the end of the episode, returned to NCIS.
In the Season 6 episodes, Legend Part 1 (episode) and Legend Part 2 (episode) which were the backdoor pilot episodes for the NCIS spin-off, NCIS: Los Angeles, Ziva and Tony had a huge argument over Ziva's supposed loyalty to NCIS as well as the fact that she had been in contact with fellow Mossad officer, Michael Rivkin. This prompted Tony to investigate Rivkin for himself and eventually led to the two agents meeting each other as well as the intense fight between both men in the last few seconds of Semper Fidelis (episode).
In the Season 6 finale episode, Aliyah (episode), Ziva performed CPR on Rivkin and accompanied him to hospital where she later informed Gibbs that Rivkin had succumbed to his wounds and died.
Hours later, Ziva, Vance, Tony and Gibbs arrived in Tel Aviv, Israel to meet Mossad who were demanding answers into Rivkin's death.
NCIS Season 7
Believed dead in the Season 7 premiere episode Truth or Consequences (episode), Ziva was nonetheless found alive and rescued by Tony and McGee, with Gibbs killing their captor Saleem Ulman with a sniper rifle.
In the Season 7 episode Reunion (episode), Ziva spoke to McGee, and he asked her why she was avoiding Tony. Later, Ziva caught Tony in the men's washroom and apologizes to him for saying that she could not trust him. She showed some of her feelings for him by kissing him on the cheek. At the end of the episode, Ziva was accepted back into NCIS, surprising both McGee and Tony who seemed happy about it.
Soon after, Ziva resigned from Mossad informing her father, Director David, via e-mail. She also submitted paperwork to officially become an NCIS agent and was eventually accepted. Ziva was granted probationary agent status pending her becoming a U.S. citizen.
NCIS Season 8Over the next several months, Ziva studied for and passed her citizenship test. She took her oath in the seventh-season finale, Rule Fifty-One (episode), becoming a U.S. citizen and a full-fledged NCIS agent and she received her American passport in Broken Arrow (episode).
In Swan Song (episode), Ziva was visibly shaken by the death of Mike Franks and broke down with Tony later comforting her in the elevator. The two were later joined by Abby and McGee.
In Pyramid (episode), Ziva was knocked out by the Port to Port Killer and eventually captured. It was revealed that Cobb didn't kill her, but he did kidnap her and stash her in his family's barn. He then gave himself up, but Ziva told the team that it was his way to get inside NCIS with Cobb later taking Jimmy Palmer and EJ Barret hostage. Ziva was also the only person who didn't attend Franks's funeral, presumably because she was busy talking to Ray at the time.
NCIS Season 9
In the Season 9 premiere episode, Nature of the Beast (episode), Ziva finally became a fully-fledged NCIS Special Agent after spending many months as a Probationary Agent.
In Engaged Part 2 (episode), Ziva traveled to Afghanistan to help rescue a kidnapped Marine who was originally thought to have died during an attack on the school the Marine was attending.
NCIS Season 10
In Extreme Prejudice (episode), Ziva and Tony survived the elevator and were eventually freed. They along with the rest of the team soon recovered from the effects of the blast and as such, aided Gibbs in searching for Harper Dearing although they weren't successful. Ziva later expressed disbelief at Gibbs going off to search for Dearing, calling Gibbs a stubborn fool for doing so although she eventually relented but still insisted that Gibbs was being stubborn.
Ziva suffered a great tragedy in Shabbat Shalom (episode) where her estranged father, Eli died after hit by machine gunfire. This prompted her to embark on a quest for revenge against the man responsible with the NCIS team aiding her albeit secretly.
Ziva eventually avenged her father but upon learning that NCIS was being investigated by Department of Defense agent, Richard Parsons, she along with Tony and McGee resigned from NCIS to protect Gibbs.
NCIS Season 11
Although she didn't appear in Whiskey Tango Foxtrot (episode), Ziva stayed in contact with Tony by sending him instant messages but upon learning that a terrorist group called the Brotherhood of Doubt were after them, Ziva later went into hiding.
With other agents
Special Agent Anthony DiNozzo
Ziva taunts Anthony DiNozzo in much the same way Caitlin Todd did before she was killed. Some aspects of Ziva's personality disturb and even intimidate DiNozzo, such as the fact that she sleeps with a gun in her hand, and her ability to sneak up on him without his knowledge similarly to Gibbs. Tony holds a higher rank than Ziva, but as Ziva is more lethal, more skilled, and better trained, they have a cat-and-mouse relationship, albeit with an unspoken attraction between them.
In Season 3 episode "Under Covers", Ziva and Tony were sent undercover as murderous assassins Sophie and Jean-Paul Rauniere and simulate having sex convincingly enough that the FBI agents who had them under surveillance began to believe that they really were having sex, multiple times. This topic came up several episodes later in "Boxed In" when Tony comments that they had not consummated the relationship. The situation is somewhat unclear, however, since in an interview with Cote de Pablo and Michael Weatherly for ET; de Pablo states that she thought they did at least once. Tony, in the Season 8 Episode "Dead Air," did not answer when McGee asked him if he and Ziva had sex.
In the Season 4 episode, "Shalom", Ziva learned that Mossad, apparently on her father's orders, had been spying on her for several months; the surveillance reveals that Tony had been visiting her at her apartment at least once a week for the past 3 months, leading to suggestions that the two had become intimate. She neither confirmed nor denied the implication in the episode, however it is established later in Season 4 that no apparent romantic link existed between them. The reason for his frequent visits are unrevealed as yet.
Nevertheless, beneath all the flirting and teasing, Ziva and Tony care very much for each other. In Season 4 episode "Dead Man Walking", Tony was surprised to see Ziva falling in love with the dying Lt. Roy Sanders, but he was supportive of her during the entire experience. In a later Season 4 episode "In The Dark", there was a reversal of roles as Ziva encouraged Tony to fight for what he loved after overhearing a conversation between Tony and his girlfriend Jeanne Benoit. Furthermore, throughout the fourth season, Ziva showed great concern for Tony regarding his frequent disappearances and his claims that he is visiting doctors' offices for tests. She initially worried that he may be having a medical problem related to his exposure to Y. pestis in Season 2 episode "SWAK." However, even after it was revealed that Tony had been visiting the hospital to see his girlfriend, a doctor at the hospital, Ziva still seemed perturbed by Tony's constant secrecy.
In one of the final episodes of Season 4, Ziva became increasingly concerned after Tony didn't answer her phone calls and comments to Ducky that "he [Tony] has his voicemail on, just like always when he's with her!" Ducky identified the jealously in her voice and commented that she is like "a mother with a toddler or perhaps a woman with a wayward lover." Although Ziva denied the suggestion that she is in love with Tony, her increasing interest in his relationship and her concern at his absence would appear to indicate that Ducky was correct and Ziva does indeed have romantic feelings for Tony.
Towards the end of the fourth season, Ziva and Tony had an increased number of scenes dripping with sexual tension and their mysterious attraction to each other. Interviews with Cote de Pablo and Michael Weatherly have also alluded to the fact that the two agents are attracted to each other, more specifically that Ziva has feelings for Tony, and that this attraction could be mutual.
In Season 5, Ziva's romantic feelings towards Tony appeared to be very strong. In the episode "Designated Target" Ziva questions Tony about soul mates. However, later in that season, Ziva's feelings toward Tony appear to have become more platonic. After Jeanne accused Tony of murder she told him to "be a man" and apologize to Jeanne, which he does. In the Season 5 finale, "Judgment Day Part 2," Tony and Ziva have a conversation about Jenny and Gibbs' "inevitable" relationship while working together in Paris.
Season 6 also shows signs of feelings between Ziva and Tony becoming more obvious. Ziva and Tony admitted to Gibbs that they miss each other, albeit nonchalantly in the first episode. When Ziva accompanied Gibbs onto the USS Seahawk as part of an investigation, she noticed Tony had three pictures of her in a bikini pinned up in his room (these pictures were taken during Judgment Day Part 1). They also had some tense moments on board the ship. The banter between them remained the same, but in "Nine Lives," Tony shows an interest in Ziva's vacation to Israel, which she takes despite the fact that she'd only just returned to the United States.
Upon finding a picture of a man on her desk, Tony's interest deepened, not knowing that the man in the picture was Ziva's Mossad partner. Tony also wished Ziva a safe trip (Nisiya Tova) in Hebrew, demonstrating that he took the effort to learn at least that phrase in her native language. In episode 8 ("Cloak"), Ziva and Tony were placed into a war game, during which they were arrested and assaulted by security personnel. They both rose to each others' defense physically — though they need to do so because Ziva broke orders not to engage and the soldiers attacked them. They shared a moment in an elevator where Ziva admits that she only fought the guards out of impulse. They both admit they are 'tired of pretending', while Tony meant he is talking about the mole hunt and lying to each other, Ziva made no such modifiers.
In Season 6 episode "Dagger," Agent Lee's sister Amanda was left an orphan at the end of the episode; Ziva and Tony looked after her in the NCIS building. Ziva was shown taking care of Amanda at her desk, watching over her as she drew; while Tony brought her breakfast. Tony notices that Ziva was upset but instead of approaching her, he glanced at her sympathetically.
In Road Kill (episode), Tony asked Ziva to go to a midnight screening of "Goodfellas" with him, but she decided to practice her air guitar instead.
In Silent Night (episode), showed the NCIS team working through Christmas. At one point Ziva and Tony were following a Vietnam veteran who stopped at the Vietnam War Memorial. Although Ziva had been teasing Tony about a former flame who has since remarried to a metro detective, she asked him if he ever regretted not having a wife and children around Christmas. Tony avoided the question and made an excuse to leave.
In the episode, Legend Part 1 (episode), Ziva received a phone call from another Mossad Agent, named Michael Rivkin who was in Washington, D.C. for an as yet undisclosed purpose, Rivkin wished to meet Ziva. In order to avoid any questions about the call Ziva lied to Tony and told him that she had a lead on the case.
In response to Ziva's evasions, Tony began prying into Ziva's affairs in order to learn more about her recent history, Tony went to see Dr. Mallard seeking information about Ziva's time in Israel after the team was dissolved because he was suspicious of her behavior. Ducky told Tony that Ziva was on assignment in Morocco and that she was almost killed. Tony reviewed the footage of the assignment, which revealed that the man who was her partner in Mossad, of whom she has a photograph, was present in Morocco. Tony asked Abby to run a facial recognition search. The search revealed that his name is Michael Rivkin, and that he is affiliated with Eli David, Deputy Director of Mossad and Ziva's father. In response to this revelation Tony deleted the results of the search and gave Abby strict orders not to say anything. Tony attempted to elicit information about Rivkin from Ziva by inquiring casually after Rivkin asking if he was in Washington. Ziva replied that he was not in D.C. any longer. He was trying to determine how loyal she is to NCIS without getting her in trouble with the director or with Gibbs.
In Legend Part 2 (episode), after ostensibly discovering the nature of Rivkin's mission in Los Angeles and his connections with Ziva, she and Tony met in conference with Gibbs, Macy and McGee via MTAC. Gibbs asked her directly if she knew Rivkin which, she answered affirmatively. Ziva's lack of openness with Tony on the subject of Michael Rivkin and her unwillingness to alter her stance by implying that she would answer only to Gibbs on this subject strained their relationship although both Gibbs and Tony are willing to do what is necessary to prevent Ziva from being hurt as demonstrated in the conclusion of "Legends Part Two" and "Semper Fidelis". During the fight between Rivkin and Tony a picture of Ari, Ziva and Tali together was broken during Tony's attempt to detain and arrest Michael Rivkin in a fight at Ziva's apartment. The fight later ended with Tony being forced to shoot Rivkin in self-defense.
In "Aliyah", Rivkin later died from his injuries in hospital, and his death triggered a series of events that saw Gibbs, DiNozzo, Ziva and Vance being summoned to Israel and eventually saw Ziva being left behind in Israel.
In Truth or Consequences (episode), the first episode of Season 7, Tony, while under the influence of a truth serum says that he "couldn't live without her," implying that he cares greatly for her.
In Jet Lag (episode), Tony and Ziva went to Paris and the hotel messed up their reservations, so they share a room. Both later claimed to have slept on the couch, though it was implied at the end of the episode that neither did.
In the episode Dead Air (episode), Ziva saved Tony from a bomb blast and landed on top of him as a result. His response is that he had missed the old Ziva and she responded by saying she could tell and Tony tells her not to flatter herself; it was just his knee (a reference to their assignment as a married couple in "Under Covers").
In Housekeeping (episode), the pair have an overdue talk, in which Tony says: 'You and I have a lot in common in that respect." They could have talked more, until Ziva's phone rings, revealing it to be Ray.
In the next episode A Desperate Man (episode) Tony shows interest in Agent Cruz's proposal.
In the season 9 finale episode, Till Death Do Us Part (episode) Tony and Ziva have a discussion about weddings. At the end of it, they give each other a look. Later on, after the bombing, Tony tells Ziva to leave as the last people are evacuated. She tells him that she won't leave without him, grabs him and leads him away. In the final few minutes, the pair escape in the elevator. As it begins to shudder, Ziva jumps on Tony to protect him and they fall over. As they are going down, they are holding hands and his arm is around her.
Special Agent Timothy McGee
Ziva and McGee are good friends. When she first moved to the United States, McGee showed her the best routes to work. Although she often joins Tony in teasing McGee, Ziva also has been shown to stick up for him against Tony as well. Ziva also has a very protective nature towards McGee, saying, in the Season 6 episode, Caged (episode), that if any of the women in the prison had hurt McGee she would "kick their ass" for him. Ziva also seems to intimidate McGee in a few episodes, but at one point he tried to comfort her when she is accused of murder. Over all they have a very good, platonic relationship.
Early in the series, Ziva was at odds with Abby as a result of the fact that Ziva's half-brother, Ari Haswari had murdered Abby's best friend and Ziva's predecessor, Caitlin Todd. Although they showed some degree of friendship towards each other, things eventually came to a head in Hiatus Part 1 (episode), leading at one point to a slapfight due to Ziva's comments about the possible death scenario of Agent Gibbs.
However, they were finally able to put their differences aside and become friends, this time on a more permanent basis. Tony, having taken temporary charge of the team made them hug each other before asking them to give each other "a deep tongue kiss", a request they both punched him on the shoulders for.
It is revealed in the Season 6 episode, Capitol Offense (episode) that Abby and Ziva were good friends when Abby put Ziva up at her apartment for an undisclosed amount of time while Ziva's home was being fumigated. Ziva later repaid Abby by giving her a cupcake which in turn was revealed to have been stolen and eaten by McGee.
By Season 6, Ziva had overcome her discomfort of accepting Abby's hugs and accepted them naturally, even giving Abby hugs as well.
In the Season 7 episode, Reunion (episode), after Abby's outburst at Ziva which detailed how she felt about the Rivkin incident, Abby gave Ziva another hug while also expressing her relief that Ziva had finally returned to NCIS, safe and sound.
Ziva has a close relationship with Donald Mallard, perhaps made upon Ziva saving his life from a rogue forensic anthropologist in "Silver War". In Season 4 epiosde "Witch Hunt", she was shown confiding in him over a pot of tea as he offered her comfort when she needed it.
Director Jennifer Shepard
Director Shepard was the one who introduced Ziva to Gibbs in Season 3 "Kill Ari Part 1." Director Shepard revealed to Gibbs that Ziva had saved her life. They had worked anti-terrorism together before Ziva joined NCIS.
Special Agent Leroy Jethro Gibbs
Ziva and Gibbs's relationship has undergone the most growth. Initially, Gibbs was very distrusting towards Ziva as she was Ari Haswari's control agent. Ziva also bore the brunt of Gibbs' anger after Caitlin Todd was murdered. After Ziva killed her own half brother Ari in order to save Gibbs' life, they shared the secret; Gibbs and Ziva are the only two who know that she killed Haswari. There is still tension, however, that continued up until the conclusion of the third season episode "Silver War" when Ziva saved Ducky's life.
Season 3 episode "Hiatus" showed how much Ziva is affected when Gibbs is critically injured in an explosion and awoke with memory loss. In "Hiatus Part 1," Ducky unintentionally chastised Ziva for not asking which hospital Gibbs was taken to after the explosion. She is visibly upset when he implies that Ziva didn't care for Gibbs like the rest of the team. She also found herself being slapped by Abby when she commented about Gibbs' possible death scenario. Ziva was shown in the bathroom following this, extremely upset by the fact that they think that she didn't care.
In the second part of the episode, Ziva snuck into visit Gibbs at the hospital in the night and begged him to remember despite his protests that he couldn't remember a single thing. When he became angry, Ziva used his hand to slap the back of her head, triggering Gibbs's memories. He remembered seeing Kate being gunned down on the rooftop by Ari and also recalled that Ziva saved his life, killing her brother to do it while Ziva broke down and cried in his arms. He remarked that he owed her later on in the episode.
Ziva looks up to Gibbs as a leader and often restrains herself from resorting to her assassin background in situations where Gibbs would not approve. Gibbs often uses this background to their advantage by choosing Ziva to interrogate certain suspects. When Gibbs saw Ziva being wheeled into an ambulance following an explosion in Morocco during the opening of Season 6, he became very worried and got in touch with her in Israel, revealing that he missed her. Prior to their parting at the conclusion of "Aliyah" Gibbs told Ziva to take care of herself and gave her a kiss on the cheek.
In the Season 7 episode, Reunion (episode), Ziva admitted to Gibbs that she was under orders from Director David to gain his trust and kill Ari in the process. Ziva confided to Gibbs that she volunteered for the mission in order to protect Ari. Gibbs replied "You killed your own brother Ziva!". Ziva having revealed this long held secret confided to Gibbs her feelings on the subject of her Ari's death and her family saying “I would have lied to you, he was my brother and you were nothing. But I was wrong about Ari and you. (...) And 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 not her orders, re-earning his trust.
When the bodies of those who had been on board the Damocles were recovered, Mossad attempted to make Ziva the scapegoat for the death of Staff Sergeant Daniel Cryer, USMC. At the conclusion of episode 7.04 entitled "Good Cop, Bad Cop." after he heard the rest of Ziva's story Gibbs whispered something to her that is still unknown. As he whispered to her, you could see her crying, but smiling.
Following investigation in to Ziva's role in the events aboard the Damocles Director Vance reconsidered an exonerated Ziva's application to join NCIS, approving it after initially rejecting it. Director Vance handed the approved application to Agent Gibbs who in turn transmitted it to Ziva, whom he called "Probie."
Gibbs has also developed a nickname for her: Ziver.
Ziva and Rivkin were part of the same mission in Morocco. During, this time a relationship developed between the two of them. Ziva acknowledged that she to an extent loved Rivkin, but that she had not yet ascertained the depth or the strength of her feelings toward him at the time of his death, a fact she admitted to DiNozzo in "Aliyah."
When she entered her apartment seconds after hearing gunshots following the fight that Tony and Rivkin were having against each other, Ziva reacted by rushing to Rivkin's side as she attempted to stop Rivkin from bleeding to death and even yelled at Tony to get an ambulance despite the fact that DiNozzo had been injured as well. Despite Ziva's best efforts, Rivkin later died in hospital which led to Ziva becoming angry and hostile towards Tony. It eventually led to an explosive confrontation in Israel where Ziva demanded to know why Tony hadn't shot Rivkin in the shoulder or any other non-vital part of his body during their fight, causing DiNozzo to remark that she really loved him. Ziva responded by saying that they would probably never know.
Ziva was forced to question whether what existed between them was real in light of revelations made by her father during his interrogation of DiNozzo, when DiNozzo tricked him into saying he "controlled everything." He later admitted he had underestimated DiNozzo.
During Ziva's partnership with DiNozzo, Director David assigned Mossad agents to follow her. Ziva's attitude towards him is to a degree one of ambivalence in the sense that she perceives that her father primarily views her first and foremost as a Mossad Agent, as illustrated by his conversation with NCIS Director Vance at the conclusion of "Last Man Standing" in which he called Ziva the sharp end of the spear. This fact was in reinforced by Ziva in episode 6.25 "Aliyah" when she told Gibbs that only Director David and herself had the power to authorize a kill order.
Since her rescue Ziva did not speak with her father at any great length because, as she pointed out to Gibbs "Eli is all but dead to me," until season eight, in which Eli showed up in Washington as a result of a terrorist threat. During that time she remained initially cold towards him, as she and Gibbs both believed that he had "left her to die in a desert." During a brief conversation in which Ziva confronted him over his passive response to the prospect of his own death, he replied, "I am saddled with responsibilities you cannot even begin to fathom...I do not have the luxury of allowing my feelings to dictate my actions. But there was a time when things were very different, when my house was filled with the sound of children laughing. You, and Ari, and Tali...there was a time." As they left to take Eli and Vance to a safehouse, Officer Hadar said to her, "His heart is hidden for a reason."
Later before he returned to Israel, Eli expressed regret over having allowed his work to take priority in his life, and they were able to come to terms with the past, as Ziva appeared to forgive him.
Ziva's relationship with her elder half-brother was extremely close. Ziva served as Ari's control officer and liaison with Mossad. Ziva initally attempted to shield Ari from Gibbs' efforts to capture or kill Ari. It was only when Ari attempted to kill Gibbs that Ziva realized that Ari had become a traitor. She was forced to kill Ari to save Gibbs's life. After his death Ziva accompanied Ari's body back to Israel for burial.
However, it was later stated by Vance that Eli ordered her to kill Ari as way to get rid of a traitor and to earn Gibbs respect at the same time; however, Ziva later revealed she saved Gibbs out of respect, not her orders.
Not much is known of Ziva's relationship with her sister. Tali was killed in a suicide bombing when she was sixteen. Ziva describes her younger sister at one point as, "the best of us", though her specific meaning is unclear. Tali appears several times in a family photograph of all three siblings, ranging in age from approximately six to sixteen.
Lt. Roy Sanders
Lieutenant Sanders was a nuclear inspector, who was poisoned by one of his partners via radioactively contaminated cigars, leading to a slow death. He formed a bond with Ziva when the team was investigating his murder in "Dead Man Walking", and she visited him at the hospital regularly. She recognized him by his orange watch cap he wore while running. Ziva can be seen in later episodes wearing his orange watch cap. In fact, in the picture of the Simpsons N.C.I.S parody, she is wearing a seemingly identical cap.
- In Timothy McGee novel Deep Six, the character based on Ziva is named Lisa.
- Ziva's NCIS hat is the same one that Tony originally wore and was forced to use as a target while on the shooting range in Marine Down (episode). With two bullets in it, Tony gave it to Abby because he didn't need it anymore. Two or three and half years later, the bullet-ridden hat re-emerged where it ended up in Ziva's possession in Silver War (episode)
- Also similarly to her predecessor, Kate Todd, Ziva tends to call Gibbs by his surname rather than "Boss" and they both sleep with their respective guns under their pillows.
- Ziva's "first time" was in a weapon's carrier.
- Is capable of lock-picking doors as seen in Deception (episode).
- Like Gibbs, Ziva is known for her dangerous driving style. She tells Amit Hadar that she will be driving the Mercedes ML when she, DiNozzo and Gibbs arrive in Tel Aviv and rendezvous with her father, Eli David, head of the Mossad although Eli insists that her mother taught her how to drive in the Season 8 episode, Enemies Foreign (episode), despite in the Season 3 episode, Deception (episode), Ziva stating that she had taught herself how to drive.
- As part of her Mossad training, Ziva also knows how to fool a polygraph.
- As revealed in the Season 6 finale episode, Aliyah (episode), Ziva's Mossad authentication code was "Gimel, Vav, Chet, Shin." (ג,ו,ח,ש).

- Ziva's actress, Cote de Pablo is originally from Chile and while Ziva is Jewish, de Pablo is Roman Catholic.
- Ziva celebrates her birthday, November 12 which interestingly enough is de Pablo's birthday in real life.
- In the episode, Life Before His Eyes (episode), in an alternate reality where as a result of Ari never murdering Kate, Ziva never joined NCIS and as such, remained part of the Kidon unit of Mossad before NCIS eventually arrested her with DiNozzo interrogating her. Her fate after that is unknown but it's presumed that she was either jailed or sent back to Israel.
- In the Season 4 episode Sandblast (episode), it is revealed that Ziva knows how to disarm explosives.
- Was seen wielding a Colt M4A1 Carbine during the Season 9 episode, Engaged Part 2 (episode).
- Like the rest of the team, Ziva has a SIG-Sauer P228 as her main weapon while a Smith & Wesson Model 340PD serves as her back-up weapon.

- Was seen eating breakfast at her desk during the Season 8 episode, Cracked (episode).
- In Dead Air (episode), two profiles of Ziva were shown: one when she was a member of Mossad and another which is her current NCIS profile.
