Don't forget that the season two finale of Star Wars Rebels airs tonight at 9:00 pm on Disney XD. The hourlong finale entitled "Twilight of the Apprentice" will feature the long awaited reunion between Darth Vader and Ashoka Tano! Season two has been a rough ride at times, but it has all been leading to this. I've never been this excited for an episode of Star Wars Rebels. Check out this preview to get a look at the return of a certain Sith Lord!
