How far along was Ben Solo in his training with Luke Skywalker when he fell to the dark side and became Kylo Ren in Star Wars? Ben Solos turn is one of the most pivotal moments in the Skywalker saga. As revealed in Star Wars: The Last Jedi, when Luke sensed darkness in his nephew and briefly believed he needed to snuff it out before it could affect the galaxy, Ben felt betrayed, and Lukes new Jedi Academy burned down in the aftermath. Lukes short-lived moment of weakness was understandable he wanted to prevent his nephew from falling the same way his father did.
