Waverly Earp is the youngest Earp sister. After losing her parents and eldest sister at young age, Waverly stayed behing in Purgatory when Wynonna eventually left as well. She grew increasingly interested in the Earp Curse and geared her education towards researching it and the outlaws Wyatt Earp had killed. In contrast to Wynonna, Waverly has a more optimistic attitude towards breaking the curse despite not being the Heir herself. At times, Waverly bitterly wondered why she couldn't break the curse herself, not realizing that it was because she wasn't an Earp to begin with.
