In Star Wars Revenge of the Sith, nnce his inevitable turn to the dark side had begun at the hands of Emperor Palpatine, Anakin Skywalker was dubbed Vader and the Anakin we knew was no more. However, when was the first time that Vader acknowledged this himself to the audience? It’s not in the films, but in the book. It’s a cool scene that takes place on Mustafar where he’s sent to wipe out the separatists before fighting Obi-Wan Kenobi.
