Star Wars: The Rise Of Skywalker - 26 WTF Moments
14. Luke & Leia Always Knew Rey Was A Palpatine

After her encounter with Kylo Ren and witnessing her own Dark Side potential, Rey exiles herself to Ahch-To with the intention of pulling a Luke and cutting herself off from the Force.
But of course, moments later she's met by the Force ghost of Luke, who gives her a soulful heart-to-heart, encouraging her to leave the island in his old X-Wing.
But before that, Luke casually reveals to Rey that both he and Leia were entirely aware that Rey was Palpatine's granddaughter the whole time, but he still decided to train her anyway.
While you can argue that this is some sort of cathartic redemption for Luke after failing to keep Ben Solo from succumbing to the Dark Side, it's still a pretty out-there revelation that's questionable in the very least.
If nothing else, it'll make rewatching The Last Jedi a little more interesting.
