Eshel was responsible for faking Ziva David's death during a bombing at the David farmhouse, as well as supplying Tali DiNozzo, Ziva's daughter, to Tony DiNozzo. He also aided her in hiding from and tracking down the one directly responsible for the bombing, Mira Sahar Azam, even infiltrating her group (he implied he did this out of unrequited love for Ziva). Eventually, he managed to track Sahar down, resulting in Ziva and Gibbs tracking her down and her seemingly committing suicide by cop to avoid arrest, as well as Interpol taking down the rest of her cell. However, it turned out the "Sahar" that was taken down was a decoy, which resulted in the real Sahar (who had posed as Gibbs' next door neighbor Sarah) hiring an infamous international mercenary known as Daniel Cross with capturing him and taking him to a condemned factory to torture him for information, with Eshel, out of delirium and mistaking her for Ziva due to the strain of the torture, unintentionally betraying Tali's existence to her. Ultimately, he died from his injuries when Ziva and Gibbs arrived to rescue him (largely due to their being delayed in freeing him from his cuffs due to both Cross having the keys on him and the floor giving way), although not before he revealed Sahar's survival and cryptically told them that they had met the real Sahar beforehand.
