When He-Man throws Skeletor over his shoulder, his scabbard and sword are missing from his back while they are present in the scenes before and after. Stranger still, the same scene is shown again during the moral Teela is giving, and this time the sword and scabbard are present.
Two-Bad remembers Skeletors last experience with the Cosmic Comet but was not even in the series at the time. Obviously his dialogue was originally written for Beast Man.
