When Eli is found, it is revealed that Vance and Eli had actually worked together during the op to stop the Russian and his hit team which was the career builder for Vance . The insider in NCIS was the same person who mounted the operation in Amsterdam and whose plan was foiled by Vance and Eli . It is revealed that the insider is Riley McAllister, former head of the San Diego field office, and that he mounted the operation so that his area of expertise, Russia, would come back into a post-Cold War play which would have allowed him to become Director . He had hired the Russian, the same man that he later sent Gibbs to assassinate in Paris along with Jenny Shepard, to kill Vance and he had set up the bomb at the safe house to have revenge on Vance and Eli .
