>>114939773Ahsoka turns Sith and makes Ezra her apprentice. She joins forces with Maul to take out the Emperor and, of course, he betrays her by joining Sidious in the end. But she anticipated that and teamed up with Vader and so the five of them settle this in combat. After a violent brawl, she's the last Sith standing having slain her enemies, her apprentice and her master.
