Phantom Traveler – The Advent of Demons
Phantom Traveler was a more important episode than any of us realized when it first aired. Beyond just revealing Dean’s hidden fears and Sam’s strength of leadership, it provided our very first introduction to demons. After viewing it again in the light of all subsequent episodes, I would submit it also served as the Winchester brothers’ practical introduction to demons. Given the revelation that demons have been behind all of the Winchesters’ travails, Phantom Traveler bears another look.
