This December’s The Last Jedi is going to be another example of how Star Wars fans shouldn’t dismiss the canon animated series, as something The Clone Wars and Rebels introduced makes a live-action appearance.
The LA Times writer who attended the Disney Shareholder’s Meeting yesterday Tweeted that there’s a scene where Rey is surrounded by orbs of light.
