Aliyah

With Rivkin later dying in hospital from his injuries despite Ziva's efforts to help him and Ziva's own apartment being destroyed in an explosion, Gibbs, Vance, DiNozzo and Ziva travel to Israel, having been summoned there at the request of Eli David, the enigmatic and powerful head of Mossad and also Ziva's father who is demanding answers in regards to Rivkin's death. As tensions rise, and based on information he gets from McGee and Abby who back in Washington are busy working on the laptop found in the wreckage of Ziva's home, Gibbs decides to leave Ziva in Tel Aviv where it is later shown that she has once again been recruited into Mossad and is embarking on a mission to stop a terrorist cell, taking Rivkin's place on the team. However the episode ends in a cliffhanger when it's shown that Ziva has been captured by the terrorists in Somalia that Rivkin had been investigating and the leader, Saleem Ulman is torturing her for information on NCIS.
