While Wynonna (played by Melanie Scrofano) attempted to trade Rosita for Peacemaker (by way of a veritable “Trial by Combat” in front of demonic nuns!), Doc aimed to put his and Wyatt Earp’s complicated past with the Clantons behind him, by negotiating a truce with Sheriff Holt after Waverly killed Mam. But just as Doc and Holt made peace, a shot rang out from behind them. Wynonna — having learned from Rosita that Mam would have been kidnapped Baby Alice’s buyer, and convinced the Clantons would have never stopped coming for her — had put a bullet into the rival heir’s back.
