"The Darkness Beneath"[]

Zed bumps into John in Heddwich, Pennsylvania while the latter is investigating an unusual death. Zed is surprised to finally meet John, and explains how she's been having dreams about him.. John accuses her of being a stalker, observing him from afar. He manages to slip away, however, Zed manages to steal his wallet. Later, Zed breaks into John's hotel room. When John arrives, Zed further explains her situation, she believes that it was destiny that brought them both together. She tells him that she has visions and even feelings that she cannot control. John doesn't believe her, so she channels the guilt and pain that he has through her. John deduces her ability as clairsentience, and puts it to the test. John puts the stolen slurry in her hand and she sees visions of Lannis' shower, and a tall crucifix. She is eventually overwhelmed, and John escapes.[2]

John warns her of the accompanying danger in his adventures, however, she remains unfazed and joins him. They both hear a siren, signalling a mine collapse, and rush towards it. Zed helps the miners evacuate. When John and the mine's manager are being drowned in slurry inside an SUV, Zed comes and saves John by breaking open the door. Afterwards, they go back to the pub.[2]

At the pub, Zed mentions how Ellis, the former priest, could be the one conjuring the evil in the mine. John once again uses Zed's clairsentience to locate Ellis' whereabouts. Zed manages to locate him in a creek, and they head towards him. There, John gives her a broom to ward off evil. After John realizes that Ellis isn't the one conjuring the evil, they both head to the mine. There, John and Zed ward off a Coblynau attacking the owner of the coal company and his son.
