Obi-Wan is in exile, so will presumably be haunted by everything that transpired in Revenge of the Sith.
Meanwhile, Darth Vader’s movie return has been teased by the same insider who predicted The Rise of Skywalker.
According to We Got This Covered’s source, who correctly leaked The Rise of Skywalker spoilers months before its release, Darth Vader has more appearances and cameos to come.
Certainly, there’s loads of space between his creation in Revenge of the Sith and downfall in Return of the Jedi.
