Not much has happened so far in Star Wars: Ahsoka, the latest Star Wars show on Disney Plus. Sure, Sabine and Ahsoka are reunited, and Sabine has resumed her training. But up until episode 4, the pair had mostly been talking about finding Ezra and Thrawn, and not actually doing it. Episode 4 shook things up in some pretty unexpected ways, including bringing in one of Star Wars: Rebels’ most complicated and important pieces of lore.
