"Return of the Jedi" concludes the original trilogy's narrative with several major revelations and climactic events. After rescuing Han Solo from Jabba the Hutt, where Leia strangles the gangster with her own chains, the heroes learn of a second Death Star. The key twist is that, unlike the first, this station is already operational, and the Rebel fleet is flying into a trap set by the Emperor.
On Dagobah, a dying Yoda confirms that Darth Vader is indeed Luke's father and reveals there is "another Skywalker," whom Luke intuits is Leia. This reframes their relationship and establishes Leia's own connection to the Force. The film's climax is a three-pronged battle: Lando and the fleet engage the Imperial navy, Han and Leia's team battles on Endor to destroy the shield generator, and Luke confronts Vader and the Emperor. During their duel, Vader learns of Leia's existence and threatens to turn her to the dark side. This enrages Luke, who briefly gives in to his hatred and overpowers Vader, severing his prosthetic hand in a direct parallel to how Anakin lost his. Seeing what he is becoming, Luke casts his lightsaber aside, refusing to kill his father and fall to the dark side. The Emperor then tortures Luke with Force lightning. Unwilling to watch his son die, Vader lifts the Emperor and throws him down a reactor shaft, receiving fatal wounds in the process. A redeemed Anakin Skywalker dies in Luke's arms after asking to see his son with his own eyes. The Rebels destroy the Death Star, and the film ends with celebrations across the galaxy, as Luke sees the Force spirits of Obi-Wan, Yoda, and the redeemed Anakin Skywalker watching over him.
