Aubrey Plaza is officially playing the green witch Rio Vidal on 'Agatha All Along,' but there are hints that she's actually Blackheart, the child of Mephisto.

When Aubrey Plaza was first announced as a dark witch in Agatha All Along, I thought, “That makes sense.” It was the same feeling for the actress who has dabbled in the dark arts, telling WSJ Magazine, “What’s better than playing in the witch-witchy worlds of witches?”

According to Aubrey Plaza, "Agatha All Along" has set out to cast a queer spell. The actress told Variety that the upcoming Disney+ "WandaVision" spinoff series is definitely the most LGBTQ+ friendly installment of the MCU.
