Lady in Waiting - S2.E5

The ""Green Earth"" comes upon a mysterious castle where they are greeted by a robot named Torg, the servant and companion of Gloria, the mistress of the castle. In complete denial about the alien invasion, Gloria claims to be awaiting the return of her grandfather, who left the castle six months earlier. Ringo, however, discovers that Gloria's grandfather passed away a year before the invasion, which means that Gloria is living in a fantasy world, out of touch with reality. When the aliens attack the castle, the Space Knights try to convince Gloria to leave with them, but she insists on remaining in the crumbling castle.
