Although Agent DiNozzo often flaunts his crass view of women, he usually doesn't have a hard time flirting with the fairer sex on and off the job. However, some women Tony has dated understandably revile him for his boorish behavior. Several women even prank Tony after he dumps them.
Tony also has a history of harboring romantic feelings for coworkers, as evidenced by his relationships with Special Agents Kate Todd and Ziva David. Throughout seasons one and two, Tony and Kate often tease one another, but mostly keep their relationship professional, until Kate's death at the end of season two. In the season nine episode, "Life Before His Eyes," Gibbs sees an alternate timeline in which Kate wasn't killed and she and Tony eventually marry and have a child. In reality, Tony mourns Kate long after her death, even naming his pet goldfish after her.
Tony's will-they-won't-they relationship with Ziva, dubbed "Tiva" by fans, spans more than 10 seasons. The two agents begin flirting with one another almost immediately during their first meeting, and they grow closer once Ziva joins the team as a Mossad liaison. By season 10, Tony and Ziva's actors were promising that "Tiva" would finally be addressed — but while Ziva and Tony do share a kiss, Ziva eventually departs NCIS, leaving little possibility of them sharing a relationship. However, Tony later learns that Ziva conceived a daughter, Tali, during the brief time they were together.
