Ahsoka featured the return of Ezra Bridger to the Star Wars galaxy. Ezra was introduced as the young protagonist of the animated series Star Wars Rebels, which concluded with him vanishing beyond the reach of the known galaxy. Ahsoka picked up the search for Ezra and Grand Admiral Thrawn, uniting Ezra's old allies, Ahsoka Tano and Sabine Wren. When their search came to an end in a distant galaxy on the planet of Peridea, Ezra was revealed to still be every bit the Jedi he once was. The season finale even included a meaningful nod to his Jedi master.
