As Asuka's depression has grown to the point that she is reduced to a catatonic state, SEELE sends a replacement pilot for Unit 02 to NERV: Kaworu Nagisa. At first Shinji and Kaworu bond and quickly become friends; however, it is soon revealed that Kaworu is in fact the final Angel and has been sent to merge with Adam in Terminal Dogma at the bottom level of NERV headquarters. Kaworu commandeers Unit 02, and Shinji engages it with Unit 01 in a fierce fight while in free-fall as they descend to Terminal Dogma. Kaworu reaches the Angel in Terminal Dogma as Shinji defeats Unit 02, but realizes that the Angel is not Adam but Lilith. He then implores Shinji to kill him to prevent humanity from being destroyed. Shinji hesitates, but finally kills Kaworu. Later, traumatized by the day's events, Shinji tries to talk to Misato, but she is too distracted by her own struggles to be of comfort to him.
