The Widows are sister wives along with Constance Clootie to the demon Sheriff Clootie. At the start of the Earp Curse, created by Sheriff Clootie, Constance betrayed them all by sealing away her husband (with the help of Juan Carlo and Robert Svane) and imprisoning her sister wives. They spent around 130 years trapped (including being kept in BBD's storage) before being released when Doc Holliday accidentally left behind his temperamental dynamite at BBD's. In doing so, the dynamite caused a massive explosion, which destroyed many long kept artifacts of the Division, while also freeing The Widows from their wooden jail.
They are currently trying to break the three seals set by Constance, so that they can free their husband from Constance's magic.
Relationship: Sister wife; Enemy
The three of them were all married to the demon Sheriff Clootie. They seem to have not gotten along since Constance claims she was his favorite because of her magical abilities. They truly became enemies when Constance sealed away their husband and imprisoned the Widows.
