I have partially solved the mystery of Ethan Chandler. Like many watching the show most have speculated that he is a Werewolf but how? What is his story? The answer is in his wiki.
"At some time in his past, he visited a desolate Anasazi village where he remarked upon the pictures the natives had painted on the rocks, citing them as his favourite painting."
For those who don't know the Anasazi also known as the Ancient Ones where an ancestral Native American tribe that vanished mysteriously and where possibly victims or practitioners of cannibalism. They practiced a form of Witchcraft that included Skin Walking ie turning into Animals. Initiation as witch involved breaking Taboo, I.e. Bestiality, Necrophilia, Murder, Incest, Homosexuality. The Navajo and other Native tribes have a similar myth involving Skin Walkers or Wendigo.
Ethan came from a wealthy family but was disowned by his father. I believe Ethan's homosexuality may be the reason why.
The American military occupied Navajo territories and did horrendous things to them. I believe Ethan was possibly in the military and encountered the Skin Walkers during that time.
I believe that Ethan is a Witch/Shaman.
