Agatha All Along has revealed a major character identity one week after the “leak” of tie-in merchandise released as part of the show’s promotion. The latest Marvel Cinematic Universe (MCU) TV series – a spin-off to WandaVision – launched earlier this month, earning acclaim and reuniting viewers with a more stripped-down version of Agatha Harkness , who is played once again by Kathryn Hahn . In the series, Agatha recruits a ragtag bunch of allies to help her regain her former powers and to learn the secrets of the Darkhold , a mysterious tome featuring dark magic spells that is made of a substance found in the Hell Dimension.

(For those who don’t remember, this is the place in which Doctor Strange is shown repeatedly fighting Dormammu in his 2016 standalone film.) Two new characters introduced in the series are generating plenty of fan theories. While their names have been mentioned in the show, it’s believed that they are actually two different characters entirely – who are far more important than they have initially been presented to be.

The latest episode of the series has confirmed one identity with the Funko Pop toys appearing to reveal the other theor to be true. *Spoilers follow – you have been warned* In the show, Aubrey Plaza ’s character is called Rio Vidal AKA the Green Witch – but fans have theorised that she might have something to do with Blackheart, due to several comic book references featured in the show, including a nod to the character.
