As the ep opens, Zarkon berates Haggar for their most recent failures. He blames the witch for making him look foolish, and she has the stones to reply with Thats not hard. Bwahahaha! Score one for the wart queen. She goes on to theorize that they've been losing so badly because the Robeasts have been weak after Voltron laid waste to their old Lazon factory on satellite Nuklon (referring to events in episode 45, One Princess to Another). Haggar reveals she's discovered a planet Zarkon's scouts have overlooked and that it's full of Lazon.
