Tim Gonzales has loving edited together a trailer for an Ahsoka Tano feature film. Using old footage from Star Wars Clone Wars and Rebels, the story is focused on Ahsoka, one of the few worthwhile Jedi, as she proctors, the galaxies' remaining Jedi and faces off against her old Master.
This arc in Star Wars Rebels tries to lend Obi-Wan's lie credentials. The whole 'Vader killed Annikon Skywalker,' i.e. that Anni wasn't a massive asshole the entire time story.
He was and sematic bullshit seems to be a form 3 lightsaber move.
