Are you a witch??
In the Flashback of this episode, Agatha is tried, not for being a witch, but for stealing information from her coven above her “age and station.”
The park and waterfall at Elder Mills Road Campsite was used for this sequence. It was a location also featured in Season 2 of The Walking Dead.
