During the recap at the start of the episode, the footage of He-Man vs Adora from "Into Etheria" has been altered. In the recap version, He-Man is seen holding his Power Sword as he confronts Adora, who is holding the Sword of Protection. But in "Into Etheria", she was holding a nondescript sword while He-Man had her Sword of Protection (having lost his own sword earlier).
As Adora watches a procession of Etherian peasants passes by the Horde Troopers, the same character models keep walking past.
When He-Man breaks through the circular door of the Rebel's cell, his right arm appear to move through the remains of the door instead of over it.
