The Toa enter the City of the Mask Makers. Tahu accidentally springs a trap that seals them in, and the group is ambushed by a horde of Skull Warriors. While Tahu and Kopaka bicker about leadership, Lewa flies off to scout ahead, leaving the other Toa to fend for themselves. Onua, attempting to prevent the Skull Warriors from keeping them in the city, accidentally collapses the bridge they took in, inadvertently forcing the Toa to stay.
