Pete dated Wynonna in high school. During Pete's 19th birthday party, Wynonna left early claiming she had cramps. In actuality, she lied so that she could leave with his brother Kyle. During The Blade, Wynonna has to seek forgiveness from those she has wronged, so she finally admits this to Pete. Pete becomes upset and beats Kyle with a pool stick. He apparently does forgive her because in Bury Me With My Guns On, Wynonna drunkenly makes out with him at Shorty's until she has a traumatic flashback of being captured by Jack of Knives. When she pulls away, Pete pulls her back and aggressively asks for another kiss until Doc Holliday breaks them apart. Pete is seen one last time in I Walk the Line as one of the many citizen of Purgatory who were poisoned by Bobo and Big Bubba. He shows up at the Earp Homestead when Wynonna is changing out of her dress. He taunts her before Willa is able to knock him out by hitting him with a cast iron pan.
