During the "Sidekicks and Henchmen" number one of the shots is of Hades, who is not a sidekick and actually has henchmen shown in and is noted as having them as heard in the number; however, he is shown because he is being iced by one of his (temporarily unseen) henchmen.
When the sequence of defeats is being viewed in the cauldron, the Evil Queen as the witch's can be seen, though she is the one watching them (and, unlike the earlier sighting of herself which she noted, she did not mention this so it cannot be reasoned that this makes sense).
