In the week since the release of Agatha All Along, fan speculation has run wild. Like its predecessor Wandavision, the Disney+ series weaves a complex, magic-focused narrative, making it perfect fodder for fan theories. Agatha All Along follows Kathryn Hahn’s Agatha Harkness three years after the Westview incident, which concluded with the Scarlet Witch trapping Agatha powerless with a false identity. Since then, she’s lived as a washed-up detective. The series also stars Aubrey Plaza as Rio Vidal, Sasheer Zamata as Jennifer Kale, All Ahn as Alice Wu-Gulliver, Patti LuPone as Lilia Calderu, and Joe Locke as the mysterious Teen.
