Ain’t life a witch?
Episode 9, “Maiden Mom Crone,” reveals Agatha, years after she killed her coven, touring from city to city along with her son Nicholas “Nicky” Scratch – whom she made, sure, from scratch. No magic. This instantly places a goal on his again from Loss of life, however she permits Agatha to have an undetermined period of time with him.
Agatha and Nicky create “The Ballad of the Witches’ Highway” as slightly ditty between them. Agatha makes use of Nicky’s angelic voice and their track a couple of Witches’ Highway to lure curious witches into Agatha’s power-zapping traps.
Ultimately, Loss of life spirits Nicky away from Agatha, and Agatha turns her grief into centuries of killing, letting “The Ballad of the Witches Highway” turn into witch lore from which she preys and advantages.
