Editor's note: Original showrunner Beau DeMayo was fired by Disney before the premiere of the first season and had announced they would remove his name from writing credits from the second season after an internal investigation and "the egregious nature of the findings..." without going into specifics. However, as of this trailer's release, DeMayo's name is included in the published credits as both executive producer and writer on the show's second season.
