Ahsoka has given Star Wars fans a something truly special in the first two episodes as it brings more characters from the beloved Star Wars: Rebels to live action. While the animated versions of the characters will always be loved, it's cool to see the characters cross into different mediums. Sabine and Hera are some of the main characters who make the jump to live action. The first two episodes of Ahsoka focus heavily on Sabine and her life after the Rebellion. While Sabine has grown her hair out long, she has a moment where she cuts her hair, which mirrors the moment when Kanan Jarrus makes the same decision.
