Evan Hudson was a human who made a crossroad deal.
Evan made a deal with a demon at the crossroads to save his wife Julie Hudson, who was dying from cancer, in exchange for his soul. After ten years, he got Julie out of the house by going to see her sister and waited for the hellhound to take him, but Sam and Dean intervened. As Sam helped protect him from the hellhound, Dean summoned and trapped the demon and offered it a deal: release Evan or be exorcised and sent back to Hell. The demon refuses at first and Dean starts an exorcism. Evan and Sam are nearly killed, but the demon eventually relents and releases Evan to live a long and happy life with his wife in exchange for her freedom.
