WandaVision Finale - 8 MASSIVE Easter Eggs, References And Secrets, Explained

If you aren't familiar with Scarlet Witch in the comics then you may be surprised to learn that Agatha Harkness isn't a villain. She can be morally ambiguous at times, certainly, but she's nowhere near as sinister as her MCU counterpart, and instead acted as a mentor to a number of different characters in the Marvel Universe - in particular Wanda Maximoff.

WandaVision ends Agatha's journey by having Scarlet Witch revert her personality back to Agnes, the charming, nosy neighbour audiences had gotten to know over the course of the series first seven episodes. Wanda initially refuses Agatha's offer for her to act as a mentor, but transforms Harkness anyway to access her knowledge on her own terms.

Is it kind of messed up? Yeah. But it's also a sort of clever, Hannibal-ised version of the pair's relationship in the comics, where instead of Wanda being taught by an elder witch, she'll get to consult Agatha as a villain as and when she needs to.

As things currently stand, it would be wise to expect Agatha to show up again in the future. Maybe not in as prominent a role, but certainly if Wanda decides she needs to learn more about her powers.
