Upon arriving all of the heroes are locked in the cell, and Gorgon tries to convince the heroes that Sibylline was in on the plan. Sibylline refuses to acknowledge Gorgon, thus it is revealed that Evil-Lyn was trying to frame Sibylline during her time at the Palace. The heroes escape the cell and battle Gorgon's guards. While Sibylline and Evil-Lyn battle it out, He-Man captures Gorgon, and Danton is returned to the throne as King.
