Ahsoka's fifth episode brought one of the most complicated Star Wars concepts to life: the World Between Worlds. There, Ahsoka found herself face to face with her former master like she has time and time again – but this time, he's there the way she remembers him, as Anakin Skywalker rather than as Darth Vader. He's a physical manifestation of her past failures, and she must learn from him to move forward and become the hero everyone needs her to be right now.
