In an interview with Deadline, Jac Schaeffer, the creator and showrunner of “Agatha All Along,” discussed the reasoning behind certain decisions made in the show’s final episodes. Schaeffer specifically addressed the moment when Agatha tells Billy Maximoff that she is not ready to see her son, Nicholas Scratch (who was officially introduced in Episode 8 of “Agatha All Along”), after she has become a ghost.

When asked if her fear stemmed from her guilt over not saving him or from having used their Witches’ Road song for evil purposes, Schaeffer acknowledged that both reasons contributed to her feelings. Additionally, she felt guilty because Nicholas “always leaned towards good” and “didn’t want to kill witches,” which left her with plenty of shame to deal with:

“It’s both. It’s the fact that she couldn’t save him, that she couldn’t find the knowledge or the power to save him, and it’s the fact that he always leaned good. He didn’t want to kill witches. He didn’t want to live her lifestyle. Instead of rehabilitating herself on his death, she doubled down, and as you said, she used his song to become essentially a mass murderer. I think there’s so much shame for her in that.”

Schaeffer examined the sequence in which Agatha was killing witches across different eras, noting that she seemed to be “someone grieving” in those moments. She emphasized the theme of shame, mentioning that it was “part of her connection point with Billy,” who reminds her of her late son:

“I watch that final sequence that we call ‘Agatha through time,‘ where the camera’s swirling around and she’s conning and killing witches through the ages, and what I see is someone grieving. She can’t get full. She can’t fill herself up, and so she’s just eating and eating and eating. I find it really heartbreaking. I think she has so much shame because she knows, but that’s part of her connection point with Billy. Obviously, he reminds her of Nicky, and she can get close to their goodness, but she’s not quite there herself if that makes sense.”
