Ziva David first came on the show after SSA Caitlin “Kate”
Todd died in the hands of Ziva’s half-brother, Ari. She became an 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 an enduring sources after her precursor,
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 attendance and as such, Ziva became a valued
and respected member, a trait which prolongs to this day. After resigning from
Mossad in the aftermath of being rescued from Somalia during Truth or
Consequences, Ziva resigned from Mossad for good and became an NCIS Special
Agent.
