picked up by the Doctor, who faints dead away just as Sumner arrives to arrest the “conspirators”—and by Reverend Lukas, who believes it to be the call of his Goddess, and who leads his followers into the tunnels where most are absorbed by the Wirrrn. Chalfont is also transformed into a Wirrrn, but Sam and Kyle manage to escape. Sumner realizes he's been deceived, and the recovering Doctor realizes that there's more going on in the tunnels than he'd previously believed. Green Fingers informs the other Lodges about Dark Peaks’ activities and executes the Dark Peaks Patriarch; the remaining Dark Peaks Foamasi are targeted and killed by assassins from the other Lodges, and eventually Ritchie's wife and son are found and rescued.
