In the season finale "Witch Way Now?", Phoebe discovers Cole is able to linger in the Demonic Wasteland, where vanquished demons go, because of his human soul. Phoebe visits him there, insisting to him that he move on to his afterlife. After she leaves, he accidentally discovers he can acquire the powers of other demons vanquished there. He becomes powerful enough to kill the beast that consumes the essence of those vanquished there and, finally, to escape. Once back in the real world, he saves the sisters' lives from a witch hunter.
