Rey and Kylo meet and fight in the desert world, while the Knights of Ren battle Finn, Poe, Chewie and the droids. Rey and Kylo still share a Force bond, which causes them to experience Force flashes of past events as they fight. Kylo and the Knights of Ren retrieve the Wayfinder and return to the ruins of the Death Star in the jungle world to unlock the arsenals location. The Resistance follows him, but are ambushed by the First Order and nearly defeated before a local alien, Klaud, helps them escape. Finn recruits Jannah and her people as reinforcements to battle the First Order, while Rey confronts Kylo. Rey and Kylo learn that the Wayfinder actually contains Palpatines spirit. The Knights of Ren are loyal to him and manipulated Kylo into freeing him. Palpatine possesses one of the knights (Matt Smith) and announces his plan to seize control of the First Order and use the arsenal to subjugate the galaxy. He also reveals that he was behind Snoke. Luke Skywalker and Han Solo appear as Force ghosts and encourage Kylo to accept the light. Kylo then join forces with Rey to stop Palpatine. Rey and Kylo defeat Palpatine, but he then possesses Kylo. He urges Rey to kill him, and she reluctantly does. Palpatine is unable to possess Rey and is destroyed for the last time. The First Order is defeated and Palpatines arsenal is destroyed. Rey mourns Kylo and Luke's force ghost appears, he ressurects him. The film is rumoured to end with a sunset. So about Lando, he doesn't do much, he's just there with the heroes. Knights of Ren also have lots of scene where they are just there. The final battle will take place on the jungle planet, the Sith Fleet will be there to fight. The death star remains will make the final battle epic and Rey and Kylo will use force flash fights against Palpatine.
