"Asuka's depression spirals out of control, so SEELE sends Kaworu Nagisa to NERV to serve as the replacement pilot for Evangelion Unit-02. Shinji and Kaworu develop a bond and become friends. However, it is soon revealed that Kaworu is the final Angel, and has been sent by SEELE to infiltrate Terminal Dogma. Kaworu commandeers Unit-02, forcing Shinji and Unit-01 to attack and defeat it. Kaworu reaches Terminal Dogma, but discovers that the giant, crucified being there is not Adam, but Lilith.[3] He then implores Shinji to kill him to allow humanity to survive. Shinji hesitates, but grudgingly kills Kaworu. Misato tries to reassure Shinji that he did the right thing, but he remains guilt-ridden over his decision to kill Kaworu."
