Mossad is Isreal's equivelant to our secret service from what NCIS has told me
Special Agent Kate Todd (Sasha Alexander) was killed in the season 2 final episode Twilight. She was killed by Ari Haswari (A rogue agent of the Israili Mossad (Israili Secret Service). Agent Ziva David (Cote de Pablo) who was to be her replacement, first appeared in the episode Kill Ari part 1, which was the first episode of the third season. She is an agent of the Mossad assigned to Gibbs team by the new NCIS director Jenny Shepherd to prevent Gibbs from killing her fellow Mossad officer and half brother Ari Haswari (even though he was guilty of killing an NCIS agent). In the 4th episode of Season 3 (Silver War), NCIS Director Jenny Shepherd officially gives Ziva a permanent position on Gibbs team as Mossad Liason Officer.
Yes there is a real Mossad.
Yes. Ziva's father is part of the storyline after Ziva is rescued from Africa by NCIS and Gibbs. The body of a US Marine who was also part of the ship Damocles that went down off the coast of Africa is found. Since Ziva and her partner from Mossad were part of the ship, Ziva's father Eli David is part of the storyline when they try to implicate that Ziva killed the Marine. But, Gibbs and Director Vance figure out this scheme and send off the Mossad officer without Ziva and tell Eli David that Ziva is property of NCIS and not Mossad.
"Mossad" is the full form of Mossad. The word translates literally as "council."
Cote de Pablo plays the role of Mossad officer ziva David. She joined the show at the beginning of season 3 to stop Gibbs from killing another Mossad operative Ari Haswari. She took over the position vacated by agent Kate Todd and stayed permanently with the team
No
The members of the Gibbs family that are dead are Shannon, his first wife, and Kelly, his eight year old daughter. They were killed by Mr. Hernandez when Shannon saw him kill a federal officer. Gibbs shot and killed him with a sniper in Mexico, where Hernandez was hiding out.
No. Ziva was captured at the end of Season 6 of NCIS in Africa by a terrorist named Salim. She leaves NCIS Team and joins Mossad at the end of season 6 and gets captured during one of the Mossad operations. In Season 7, Gibbs and team go to Africa and rescue her from the terrorist group and bring her back to USA.
