Marvel Studios first TV series for Disney+ should be called ‘HahnVision’. WandaVision, the post-credit scene posing as a TV series, has cast a spell thanks to Kathryn Hahn’s overly friendly neighbour Agatha, who has pushed fans into speculation overdrive about her true nature. Well, now we know because in episode 7 it’s revealed she’s a powerful witch, Agatha Harkness (see: dudes on Twitter who have read all the comics for more info).
