Overview:The Gorgon returns to the museum from her exhibition and turns Mortimer into stone. The group place Merlin's crystal into a box, summoning Matt and Nikita into Purgatory. Alex tries to shine a mirror in The Gorgon's face so she turns herself to stone, but the group finds out she is immune to this. The YouTubers split up into two groups. One group is responsible for completing the statues to gain a piece of a medallion. The others enter the Minotaur’s maze to get the next piece of medallion needed to claim the next key. However, before they can get the key they must turn The Gorgon to stone. They must do a challenge to assemble a puzzle Colleen and Matt were winning but Nikita knocked over Colleens puzzle leaving Matt and Colleen to lose.
