Occasionally the director would miss something during the production of an episode. However the following mistake is a pretty big one to miss. During the opening scene of the season two She-Ra episode "Above It All" a group have gathered to listen to Bow's storytelling. Oddly we can see Swift Wind in many of the shots even though Adora has not yet transformed into She-Ra! A few minutes later the errors is corrected when Adora finally transforms into She-Ra, transforming Spirit into Swift Wind!
