Wes Bailey was a patient of Mia Vallens.
Background[]
Buddy pretends to be Erica to Wes Bailey.
Wes' wife, Erica, suddenly died of a heart attack. Because of his sadness, he went to see psychologist Mia Vallens. The latter, a shapeshifter, made him move on by taking Erica's form and saying goodbye. However, six months later, Wes returned home one evening and found Erica at home. As she hugged him, Erica (who was actually the shapeshifter Buddy) grabbed a knife from behind Wes and brutally stabbed him in the stomach, killing him. The couple's neighbor saw Erica leave the house right after Wes was killed, which caught the attention of hunters Sam and Dean Winchester.
