Hothead finds an unconscious young woman lying on a hill near a wrecked ship. When she awakens at Castle Gradam, she reveals her name is Lisa, and that she is an escaped Earth slave from the Galran Empire. However it is soon discovered that she is in fact a Galra operative when she attempts to blow up the castle, and that Daibazaal has (falsely) promised to free the other slaves in exchange for her and her newly-Beastified brother's cooperation.
