Agatha All Along hasn't been shy about acknowledging its WandaVision roots. From its Mare of Easttown-inspired opening to its bursts of suburban humor, Marvel's latest Disney+ series has been eager to remind fans of the fun they had watching its parent show three years ago. Thanks to certain lines and moments (see: one character's assertion that Wanda Maximoff is "definitely dead"), Agatha All Along has even poked fun at the Marvel Cinematic Universe's fandom and its theory-crafting tendencies.
In its latest episode, titled “Through Many Miles / Of Tricks and Trials,” the series takes that playful spirit further by indirectly acknowledging the biggest incorrect theory from WandaVision's original nine-episode run. In doing so, Agatha All Along has confirmed the existence of one particular demonic comic book figure in the MCU.
