The following article contains spoilers for WandaVision.
While it seems WandaVision won't be returning for a second season, the hit Disney+ series is getting a spin-off with Katharyn Hahn's villainous Agatha Harkness taking centre stage. The series is in the early stages of development but is described as a dark comedy heavy on the comedy. WandaVision head writer Jac Schaeffer will oversee the as-yet-untitled series as showrunner, but at the time of writing, the project has not been given a series order, and Disney has made no official statement.
In WandaVision, Hahn appeared as though she had a fun supporting role as Wanda and Vision's nosy neighbour Agnes who seemed just as confused as the rest of the residents as to what was happening. However, Agnes turned out to be a powerful witch who survived the Salem Witch Trials and has set her sights on extracting Wanda's powers. In true WandaVision style, the reveal of her identity was anything but ordinary, with the catchy song Agatha All Along allowing Hann to go full-on comic book villain. Agatha even cast a spell over the Billboard Top 40, with the short song reaching number 36 in the charts.
Hahn has reportedly signed a new multi-project deal with Marvel that will see her wonderfully evil Agatha appear in a range of MCU titles over the next couple of years. So, it is fair to say that Wanda's spell to wipe her memory and leave her in the town wasn't as permanent as expected. That said, the MCU is diving headfirst into the Multiverse with What If, Spider-Man: No Way Home, and next year's Doctor Strange in the Multiverse of Madness, so it might not be the same Agatha at all.
WandaVision is available to stream on Disney+, and Spider-Man No Way Home arrives in cinemas on December 17.
