The episode title pretty much sums it up, but...Wow, what an episode!  Is the "Skin-Walker" legend more than just that?  After all, legends are always based upon aspects of real-life...Eerie, creepy and terrifying facts about the lore and (not necessarily) myths of Native American Shapeshifters...PLUS, "One Last Take" on the significance, meaning and potential reality of SPIRIT ANIMALS!  This is one episode you can't afford to miss....Well, you can "afford" to, but you know what I mean....;-)
