is found uninfected, she continues to stay with Tony, lying about her condition to him even though she knows that the risk of infection is still imminent. She is devastated as he seemed about to die, and relieved as he survives. Kate's death would have a serious impact on Tony, which along with other events make Tony "grow up" during the following seasons. As shown in the episodes "Kill Ari 1 & 2", the team struggles to deal with the shooting, culminating in a scene in which Tony and McGee mourn over the dead body of their deceased colleague in Ducky's autopsy room. After Kate's death, like the other characters, DiNozzo also has a vision of her postmortem. Typical to Tony's chauvinistic personality, Kate appears in the Catholic schoolgirl uniform that he had been asking about in the episode "Bikini Wax". After telling him that she always knew what he was thinking, she realizes that she is wearing the uniform and quickly berates him.

In the season ten episode, "You Better Watch Out", Tony is shown to have a goldfish named Kate, whom he teases like his former partner (telling the fish she's "getting fat"), despite clearly doting on it. Special Agent Ziva David Throughout seasons four to ten, Ziva and Tony exhibit a high level of chemistry. Although their relationship was not explicit until the beginning of season 11 (when David's actress left the show), the close bond between the two ultimately resulted in their daughter, Tali. Special Agent E.J. Barrett E.J. is introduced in the season eight episode "One Last Score". She took the lead investigator position in Rota, Spain, which Tony declined. Tony and E.J. begin a sexual relationship shortly after her arrival, much to the disapproval of Gibbs. In a flashback in the season nine premiere Nature of the Beast, Tony confronted E.J. about her removal of a microchip from the body of a victim of the Port-to-Port killer. Subsequently, Tony suffers memory loss and E.J. disappears while another agent is killed. E.J. emerges from hiding in the episode "Housekeeping" and discusses events with Tony at a safe house while he is furious with her for her abrupt disappearance, but they go their separate ways after the killer is apprehended, with E.J. urging
