Part of the Earp curse is that every generation, 77 of Wyatt Earp's kills (called Revenants) return from Hell to RAISE Hell in Purgatory. It's up to Wynonna to banish them back to the underworld, but only her gun, Peacemaker, can do that. The following is the complete tally of the 77 that Wynonna (and Peacemaker) have sent back to Hell.
Episode 13 - Willa Earp: Fratenizing and dating the head Revenant in charge, Bobo Del Ray, lead to Willa's demise. Wynonna had no other choice but to put her long lost sister down. And while Willa wasn't a Revenant, she was guilty by association, she'll be forever immortalized in this gallery.
Episode 11 - Bar Revenant: Well, will you look at that? Willa continues to come into her own - Earp style. When this revenant gets mouthy with Willa and Wynonna, Willa does the honors. Bye, bye bar Revenant.
Episode 8 - Jack: This Revenant who had a penchant for removing the organs of women while they were alive, must have been a relative of Jack The Ripper. Also? Judging by his outfit, we're going to assume that he was a big fan of Doctor Who. Also? He was the last of the Seven that Wynonna set out to kill. Boom!
Episode 5 - Fish & Levi: This was one of Wynonna’s few mercy kills. Fish, who was actually a good guy despite being a Revenant, just wanted to find his lover Levi, who Doc drug across the Revenant safety line. Hence the awful facework. Not wanting them to go back to live under Bobo Del Ray’s rule, Wynonna put them them both out of their miseries.
Episode 3 - Sam: See that black goo? That means that he's dead (again) but his soul managed to escape- finding a new host in Wyonna's dear friend, Shorty (forcing Wynonna to kill him in order to send this Revenant back to hell).
